Funding Nemo

The Coastal Jaeger Battlegroup need the Navy Nemo.

That’s the short version of the story. Acquiring the Patria Navy Nemo advanced mortar system mounted on a small vessel that can keep up with the other crafts used by the Coastal Jaeger Battlegroup is exactly the kind of force multiplier that is needed if today’s slimmed version of the Finnish Defence Forces is to be able to not only survive but also to conduct offensive operations on the modern battlefield.

As I touched upon in my post on the Åland islands, the archipelago is a battlefield unlike any other. There is no single frontline, and anyone attempting to control all islands will soon find themselves overextended to the point where they are unable to defend against a determined attacker. Instead, the defender has to concentrate their forces on strategically important islands, from where they can then extend zones of control over the lesser ones. This creates a situation of islands becoming isolated strongholds, with periods of calm being interrupted only by raiding or outright assaults. The fighting is usually swift and brutal, taking place at extremely close ranges, and with a very limited ability to either reinforce or resupply the forces involved, or to evacuate wounded for that matter. Any retreat will usually have to take place over open water under fire, further increasing the determination to stay in the fight for both sides. To only solution for the attacker is therefore to rely on surprise to create local man- and firepower superiority on a single island, throwing the defender literally into the sea. Naturally, on a grander scale this calls for a very delicate balance between overextending and leaving gaps in the defence, with the Hanko campaign of 1941 probably being the best historical case study to shine light on the dilemmas. Here, the Finns continuously stretched their defences too thin, and despite the Soviets strategically being on the defensive, they managed to score a number of operational victories by being active, keeping the initiative, and playing on the strengths of the attacker.

In the end, it was the German Army Group North and the fall of Estonia that sealed the fate of Krasnyi Gangut, the Soviet naval base in Hanko. After it became clear that the continued value of occupying the peninsula was limited, the Soviet withdrew the forces to Leningrad to shore up their defences there.

Many things have changed since the summer of 1941, but the basic premises remain the same. The Finnish Operational Forces, the spearhead of the defense forces and the units tasked with fighting the decisive battles, include a Coastal Jaeger Battlegroup, heir to the former wartime Coastal Jaeger Battalion (RANNJP). This is the sole unit in the Finnish wartime TOE which has offensive operations in the archipelago as its main task.

The Finnish Coastal Jaeger is a light infantryman. This is natural, as the archipelago rarely sees anything heavier than what can be carried on the back of the soldiers themselves. No-one is going to drag a MBT onto an island measured in acres, and even if an IFV could potentially be a formidable adversary after having swam out, it would probably soon find itself hampered by the close quarters of the battle. However, to establish the shock and awe needed for an amphibious assault, indirect fire will play a key role. The individual companies of the battlegroup feature light mortar troops with three 81 KRH 71 Y, 81 mm light mortars, and these are carried on two landing crafts. These are relatively light, and need to be set up on a neighbouring island within 5 km of the battlefield to be able to participate in the landing. Alternatively, they can be brought onshore and support the landing from the beach, as long as the island is big enough.

But while 81 mm mortars are a handy weapon for suppressing fire, the battelgroup will need heavier rounds if it is to be able to dig up an entrenched enemy. This is where the heavy mortars come into the picture. The TOE of RANNJP featured a single mortar battery with six heavy 120 KRH 92 mortars, towed by trucks. The basic mortar is a competent if somewhat unspectacular weapon. It is able to fire HE, flare, and smoke rounds, and features a max range of approximately 7.5 km while weighing in at 500 kg in its assembled state. However, it is the sole unit in the battlegroup that is carried on trucks and not on fast landing crafts, significantly reducing its effectiveness and tactical flexibility. This is especially problematic as the archipelago is a prime area for the indirect approach, with tactics such as skipping islands and isolating enemy strongholds by cutting off their supply lines. This becomes vastly harder if any potential targets have to be within ~7 km of controlled mainland where the small convoy of trucks and mortars can pull aside and set up positions. Further complicating the problem is the fact that the once mighty Finnish coastal artillery has been reduced to a shadow of its former self, with most of the fixed installations having been disbanded and the towed pieces having been transferred to the army. In conclusion, the Coastal Jaeger Battlegroup need a organic unit that can keep up with its fast assault crafts, and which can deliver heavy and accurate indirect fire support.

Luckily, the problem isn’t new, and as mentioned Patria has had a solution ready for over a decade. Originally this centred on the joint Finnish-Swedish AMOS twin-barrelled mortar turret. This was originally planned for and tested on the Swedish CB 90 H, but the 15 m long and relatively narrow vessel proved too unstable to carry the turret, and the number of rounds carried was also limited. The Swedish forces started planning for a new vessel, SB 2010, designed around the turret, while the Finnish Navy instead focused on a lighter single-barrel version. The former was eventually destined to remain on the drawing board, while the later became the Patria Nemo, which was successfully tested on a modified Jurmo-class fast landing craft. No order was however placed, and the focus of the Finnish coastal jaegers moved from the 15 m long Jurmo to the larger and significantly more versatile 18 m Jehu-class (also known as U700-class or Watercat M18 AMC).

Compared to the Jurmo, the Jehu marks a significant step up in all-round capability, including firepower (sporting a RWS with E/O-sights and 40 mm grenade-machine gun with a coaxial 7.62 mm PKM), protection (both ballistic and NBC), and mobility. Through and through, the Jehu is simply the best vessel in its (specialised) class worldwide, and has considerable room for up-gunning in the form of weapons fitted for but not with. This includes the Nemo, where the bigger hull would remedy the space and stability issues encountered on smaller vessels.

The Nemo-Jehu is exactly what the coastal jaegers need. Here is a highly mobile system, mounted on the same hull as their primary means of transport. It allows for both direct and indirect fire, and can also fire on the move. The mortar allows for operation of all standard 120 mm rounds, and has all the niceties one can expect from a modern turreted system (quick response time, MRSI with up to five rounds, high rate of fire, full NBC protection, …). While one should always treat the marketing slogans for modern systems with a grain of salt, there’s still plenty of situations where the simple number of barrels count for more than MRSI-capability, there is little to deny that three or four Nemo-Jehu’s would offer significantly better and more flexible indirect fire support than the current setup of six towed 120 mm mortars. The only benefit provided by the later would be the fact that they are easier to replace than the highly specialized vessels.

What it comes down to is, naturally, cost. In today’s cash-strapped defence forces, there are a number of programs that are all urgent and crucial for the units in question. Still, it is hard to argue that we should invest 34 million euros in new assault crafts for the coastal jaegers, and then not go the extra mile to buy three or four additional vessels to be able to effectively support the first twelve during amphibious landings. The unit price for the first twelve Jehu’s, a program cost of 34 million euros split equally over the whole series, is roughly 2.8 million euro per boat. The Nemo-Jehu is probably in the same range, depending on the number of hulls ordered, as the engineering costs are markedly lower. The concept is already here.

The Coastal Jaeger Battlegroup need the Navy Nemo. As the major units of the navy are starting to take shape, forgetting the smaller craft could prove to be a costly mistake.

In the interest of full disclosure, the company I work for is a component supplier for the Jehu-class.  All info given in this post is completely based on open sources, and represents my personal opinion only.

Back in Control

This morning the Swedish Commander in Chief surprised the better part of the Nordic defence community by announcing that the mechanised company recently deployed to Gotland as part of a readiness check won’t go back to Skövde where its parent unit, P4 Skaraborg Regiment, is based. Instead, active as of 0700 this morning, it is stationed on Gotland in defence of the island.

This is a drastic move. The new 18. Battlegroup, a mechanised battalion with a mechanised and an armoured company plus support units, is already in training on the Swedish mainland. However, it was planned to become active in 2018. This has now been changed to mid-2017, which together with the decision to transfer one of the existing companies to the island to cover part of the interim year is a major step (the company won’t have to cover the whole time alone, but the duty will be transferred to another unit at some point). Not only is there an economic issue at stake, with already the original Battlegroup Gotland putting added strain on an already stretched defence force, but also the personnel factor. Soldiers and officers with their homes and families in Skövde woke up to the news that they will be staying on the island until further notice. In a time when the defence forces has had a hard time filling its personnel needs, this is certainly not a decision taken lightly.

The unit has been laughed at, including being called “The Kamikaze Company” on behalf of its small size (150 persons), and Russian propaganda noting with poorly hidden contempt that the soldiers aren’t yet allowed to use the local firing range.

However, the situation isn’t as desperate as it seems at first glance. For anyone planning to invade the island, there is a huge difference having to meet no active soldiers at all, or having to do with mechanised infantry including their CV 9040’s. These modern infantry fighting vehicles come equipped with the classic 40 mm Bofors sporting a mix of modern APDS and HE ammunition. In effect, it is no longer enough to land an airliner full of paras on Visby airport, but the invaders need to bring more men and heavier weaponry. This means further preparations involving more people, leading to a lower likelihood of achieving surprise, in turn allowing the defenders greater notice and the possibility to further strengthen their defences with more units. Even in the face of a full-blown amphibious invasion, the unit together with the local Home Guard should be able to conduct a fighting retreat towards Visby, making sure the harbour is in Swedish hands long enough to allow the rest of the regiment time to arrive.

What is worrying, however, is the fact that the temperature around the Baltic Sea seems to have dropped drastically in just a few weeks. Swedish blogger Jägarchefen notes that the last three weeks have featured a number of stern statements by both Swedish, US, and Russian officials. This has now culminated in the Swedish decision not to stand down after a readiness exercise. What exactly has caused this development is not publicly known, but at the same time US vice-president Biden gave Sweden some form of security guarantees in the face of Russian aggression, Swedish officials have quietly upgraded the risk of an “isolated attack on Sweden” from “improbable” to “low”. Rumours are also circulating that the recent Russian exercise caused the Swedish Defence Force to very nearly raise their readiness, something which has not happened since the Russian invasion of Crimea. From the Finnish viewpoint, there is a natural question that deserves to be asked:

What does the Swedish Commander-in-Chief know, that our politicians pretend they don’t?

On Research Vessels and AIS-tracking

The appearance of Russian research vessel Akademik Nikolaj Strakhov (named for the 19th century philosopher with the same name) just outside of the Swedish island of Gotland last week caused some discussions on social media. In this blog post I will address two topics that caused discussion, controversy, and sometimes, misunderstandings: The vessel itself, and the AIS-system used for tracking its whereabouts.

Akademik Nikolaj Strakhov

To start with the vessel is built in Finland in the mid-80’s as one of four sisterships of the Akademik Boris Petrov-class. It is government owned, and apparently operated in a geological research role. Interestingly enough, the vessel seems to have spent over a year broken down in the Indian Ocean, due to bureaucracy and a lack of funds. It is however now back in business, and homeported in Kaliningrad.

The towing of the vessel following it breaking down outside of the Maldives in 2013

To be clear, the vessel behaves exactly as a geological research vessel would. It reported restricted maneuverability, and slowly coasted along on a general North-South course just outside of Swedish waters. “Restricted maneuverability” is a defined term that refers to a vessel “which from the nature of her work is restricted in her ability to manoeuvre as required by these Rules [COLREG] and is therefore unable to keep out of the way of another vessel”. This can be due to e.g. the vessel conducting dredging, cable-laying, towing, mine-clearing, or launching aircrafts. What it doesn’t include is vessels that have broken down, which instead use the signals associated with “not under command”. However, general research work often do fall under the restricted maneuverability, and e.g. survey work would certainly require the vessel operating at slow speed while unable to deviate from the planned course.

The problem obviously is that the Soviet Union and Russia has a long tradition of using civilian vessels such as trawlers and research vessels for more or less clandestine intelligence gathering. It is telling that the only picture of an Akademik Boris Petrov-class ship on Wikimedia is of Strakhov’s sister Lavrentyev being intercepted by Japanese and US forces. And with the Russians regularly employing all parts of the state apparatus in their full-spectrum conflict approach, it would be naive to believe that this scheme hasn’t continued. Is the Akademik a spy ship? That is impossible to say. FVÖ16, this year’s largest exercise conducted by the Swedish Air Force, saw Gotland having being host to a number of units. Also, the Nynäshman-Ventspils and Stockholm-Fårö-Ventspils subsea cables are found in the area, as well as the brand new Markgrafenheide-Helsinki cable, meaning that even if the vessel would only be conducting bottom mapping, the research would indirectly produce data which would be of some value for the Russian Armed Forces.


The AIS system is best thought of as the maritime equivalent to the frequently discussed transponders carried (or not) by aircraft. For the technical part, it sends packets of data over the normal VHF-band, which usually include the vessel’s name, position, heading/course, speed, and potentially a number of other pieces of information (turn rate, heel, destination, ETA, current mode of operation, …). The system provides a simple and inexpensive way of keeping track of traffic in an area, as well as quickly recognising important features of other ships operating in your area (such as restricted maneuverability). It is also employed in distress transmitters, with AIS-SART transmitters being small self-contained AIS-transmitters  that can either be brought along in a survival craft or, in the worst case, be left floating when a vessel sinks.

However, it is important to be aware of the limitations of AIS.

To begin with, as noted the AIS signal is basically just a pre-programmed and automatic VHF-radio. It has limited range, which can be limited further by bad weather or atmospheric conditions. It is also possibly to turn it off by the flick off a switch, in case you are heading somewhere you don’t want to be seen. There are legitimate scenarios where this is the case, with e.g. merchant ships turning off their transmitters if they fear they are at risk for a pirate attack.

The system has also started to show its age, and while this contributes in making it affordable, it also means that it is designed with openness prioritised over security. As such, it can relatively easily be compromised by hackers, which can feed false data into the system. This can include drawing fake tracks, creating non-existent vessels, or making existing ones disappear. While this caused quite a stir when a publicised case took place a few years back, there has so far not been any major incidents caused by hacking the system. One issue working against any malicious use being successful is that there are a number of happy amateurs, commercial, and state actors following up the marine traffic around the globe, so any attempt would be discovered in a relatively short span. Part of the reason behind this is that there regularly appear faulty information on the AIS system due to broken sensors or operator error. However, in the same way that transponders shouldn’t be seen as telling the whole truth on airliner traffic, AIS shouldn’t be trusted to convey the whole picture of maritime traffic.

Squadron 2020 – Made for the Finnish Coastline

laivue2020_uusi_logoThe acquisition of four multi-purpose corvettes by the Finnish Navy as part of the Squadron 2020 (fi. Laivue 2020) program received some serious flak by BGen (ret.) Lauri Kiianlinna in Helsingin Sanomat last Friday, of exactly the kind I warned would become widespread due to the Navy’s somewhat lacking marketing of the project. While I agree with Kiianlinnas assessment that the Army need further funds and that the ground based air defence needs to be fleshed out, many of the points raised in opposition of the project are either based on misunderstanding or in some instances flat-out wrong. As noted, this is partly a failure on the part of the Navy, who in today’s economy more than ever has to explain not only what they need, but also why. A simple “Trust us, we’ve checked the issue” (while correct) is no longer enough to the public or the other cash-strapped branches of the defence forces.

Finland is for all practical purposes an island, and the only way we will keep our supply lines open for any extended time is through cargo vessels that enter the Baltic Sea in the Danish Straits, before sailing up the length of the Swedish coast until arriving in Finnish ports. This means that while the navy cannot win any wars for Finland, it can certainly lose them.

As such, Finland will need a navy to escort our merchant vessels at the very least until they reach Swedish waters. Currently this is done by a number of smaller vessels operating together to perform different individual roles:

  • The Hämeenmaa-class minelayers are operating as the squadron leader/flagship, while having a limited ASW- and anti-air capability
  • The Hamina-class FAC provide anti-ship missiles and a limited anti-air capability
  • The Rauma-class FAC provide ASW-capability in the form of the only dedicated submarine-hunting sensor in the Finnish Navy as well as featuring limited ASW-weaponry. If the towed array is left home, it can instead use anti-ship missiles

It should be noted that a three-ship squadron like this faces a number of tough choices:

  • A total of no more than 16 ITO 04 (‘Umkhonto’) surface-to-air missiles featuring a short 14 km range are available for air cover
  • For the Rauma to find a submarine it needs to listen for it, meaning that it would prefer to keep some distance to the other ships. However, doing so lessens the protection offered by the short-range ITO 04 mounted on the other vessels
  • None of the vessels sport any torpedoes, so If a submarine is found the vessels will attack it by driving towards it well within torpedo range while firing ASW-mortars

These ships, especially the Haminas, are very potent for their class. However, there is only so much equipment that can be fitted into the limited hull sizes available. Both of the FAC-classes also lack the ability to operate in ice, due to their light (and vulnerable) aluminium hulls. Their small size also seriously hamper their endurance, forcing them to return to port at short intervals. For a navy in which hiding in the cluttered archipelago is a central part of the doctrine, having to frequently return to fixed points to bunker up on fuel, supplies, and weapons, is far from ideal.

The need for bigger hulls

The size is not a product of the urge to venture further into the Southern Baltic Sea or on international missions, but of the need to provide vessels that are able to operate in Finnish waters year-round, able to handle the varied threats they may encounter.

This is where the main problems of the opinion piece are. The new ships will not further strain the limited air defence resources available, they will not be sitting ducks, and they will not be restricted by ice. On the contrary, they will be able to hide better than the current fleet due to being less reliant on visiting known locations, they will carry their own air defence, and their big steel hulls will offer them ice-going capability as well as better resistance in the face of battle damage.

Of great interest is the vertical launch system (VLS) seen on the render pictures released by the navy. I have discussed these in greater detail on the blog earlier, but the conclusion is that they would bring a marked increase in the air defence of not only the ship themselves, but also of the general area of operations. In fact, in the best of world’s we might even get to see the Aster 30 onboard the corvettes, which would finally give the (southern parts of the) country a measure of protection against ballistic missiles. As such, the claim that these would tie up valuable air defence resources is wrong, and instead they might actually free up army units.

The discussion regarding the range of the weaponry is somewhat simplified. The max practical range is nowadays rarely reliant on what the sales material claim the missiles are capable of. Instead, the main question is how far out the enemy can be accurately located. Another issue that one rarely want to fire all missiles straight at the enemy, because A) it makes it easier to defend against compared to if the salvo is routed to come in from different angles at the same time, and B) it gives the enemy a vector to follow back to the location of our firing battery. To sum it up, the Navy wont fire anti-ship missiles, either from trucks or naval vessels, to Gotland any time soon, regardless of how the range rings look on the map.

When it comes to anti-submarine weapons, it seems like we will finally get a ship armed with torpedoes and proper sensors, which will make it possible to locate and fight off one of the most elusive threats our shipping lanes currently face. This is especially important as we currently lack any kind of airborne ASW-capability, and the only way to find submarines lurking outside of our archipelago is through the use of ships.

The other possibility is to assume that we can keep our waters protected without own ships, which is an interesting concept on paper. By employing shore-based anti-ship and surface-to-air missiles we would be able to ward off any intruders, or so the theory goes. However, by the very nature of these systems, they lack the operational mobility to keep up with merchant vessels moving in Finnish waters along the coast, and as such need to be pre-positioned so that they can cover the expected enemy attack vectors. They then need to be fed target data, and feature a redundancy in both firing units and sensors, so that the enemy isn’t able to create a gap in our defences where they can strike at our lifeline with impunity simply by knocking out a battery or two.

This can all be done, but to be fair it is highly doubtful if this advanced network of mutually supporting coastal sensors, truck-mounted anti-ship batteries, submarine hunting helicopters, and surface-to-air missiles, would be any cheaper than the corvettes. Crucially, the system would lack the flexibility offered by a surface squadron of multirole vessels, which are able to move with the merchant convoys, carrying their own sensors as well as weapons to fend of air, surface, and sub-surface threats. The similarities to the discussions regarding ground based air defences contra getting new fighters are striking. This isn’t a case of “either/or”, but rather that a strong defence will have to be made up of multiple layers of different systems with their own strengths and weaknesses working in unison, and I fully expect the Navy to start looking into replacing the truck-mounted MTO 85M at some point in the future.

When it comes to coastal defence, I would like to see Squadron 2020 and ground units being networked with our HX-fighters, to let the fighters provide accurate target data through the use of a modern data link while letting the others act as silent ‘shooters’ with their radars turned off.  This is a concept which for example Saab already has as an option for which includes both their air units and naval command and control systems, and one would assume that there is a requirement for HX and Squadron 2020 to be able to communicate with each other.

It isn’t about the Navy against the Army or the Air Force. At the end of the day, we’re all in this together.

Epilogue: The Panssarilaivat – White Elephants of the 1930’s

The Väinämöinen-class of two coastal defence ships (fi. Panssarilaivat) has long been regarded as the schoolbook example of wasted money. Being expensive and manpower intensive, they took almost no part in the Second World War, and the navy still managed to lose one of them with a large loss of men during one of their few wartime sorties.

However, while I agree that it was a strange decision to invest in major surface units when the army lacked anti-tank weaponry and artillery shells, the other side of the story is often forgotten. The war did play out in an extremely surprising way. The Winter War was fought almost entirely while the sea was frozen, and when the Continuation War broke out it didn’t take long until the Germans had occupied the whole southern coast of the Baltic Sea from the Danish Straits up to the outskirts of Leningrad. This made the relatively strong and modern Baltic Fleet trapped in their bases around the city until the end of the Continuation War. The exception was the submarine fleet, which every summer broke out to try and wreak havoc amongst Finnish and German shipping in the face of Finnish and German subchasers and submarines (until the Germans and Finns installed two nets over the entire Gulf of Finland!).

If things would have played out differently, and Finland would have had to stand alone, two floating coastal fortresses could suddenly have proved to be rather useful after all.

Estonia Leads the Way

In the stream of Russian snap drills that have come to be part of the ”new normal”, news broke today of a more surprising snap exercise, held by Kaitsevägi, the Estonian Defence Forces. In a surprise move, Estonia has launched an unannounced exercise involving the whole standing army made up of two infantry brigades, the aptly named 1. and 2. Jalaväebrigaad (est. infantry brigade). The exercise does not include calling up reservists.

What is truly astonishing is the rapid expansion undertaken by the Estonian Defence Forces as a whole. Before the Russian invasion of Crimea the Estonian army consisted of a single light infantry brigade, featuring wheeled transports in the form of the Patria (Sisu) XA-180EST and XA-188 APC as the only vehicles with any kind of armour protection, and while a nice long-term expansion plan had been drawn up already in 2007, little of this had materialised. The Estonian army was a professional force with ample of experience from Afghanistan and Iraq, as well as from UN missions, but it was woefully undersized and lacked key weapons systems and capabilities to be able to defend its homeland from an aggression by a modern mechanized force.

However, everything changed with the Russian invasion of Ukraine, and a number of planned procurements shifted into high gear. These included the acquisition of surplus CV9035NL infantry fighting vehicles from the Netherlands (also source of the earlier XA-188) and modern Javelin anti-tank missiles, of which especially the former is a key element in the 1. Jalaväebrigaad’s transformation into a (light) mechanised brigade. The years since have also seen the delivery of the first Mistral M3 short-range air defence missiles, which together with the Saab Giraffe radars they are networked to significantly boosts the integral air defence capability of the 1. Brigade.

The numbers have also grown, with the Kaitseliit (volunteer Defence League, roughly corresponding to the National Guard) receiving a record number of applicants in 2015 and crucially the 2. Jalaväebrigaad being activated in 2014. The brigade might be young, but it traces its roots back to the Estonian War of Independence and the Julius Kuperjanov Partisan Battalion (est. Ülemleitnant Kuperjanovi partisanide pataljon). With the 1. Brigade being formed around the capital of Tallinn in the northern parts of the country, the new brigade is situated in the south-eastern parts of the country, proudly wearing the arms of Livonia and colours of the city of Tartu, opposite the border of Pskov and the Russian 76th Guards Air Assault Division.

Even more importantly, the army has stepped up its training regime, both in size and in complexity. The annual spring exercise of 2014, Kevadtorm 2014, was the largest held in the country up to that date, but was surpassed by the corresponding Siil 2015 exercise the following year. Siil 2015 was not only the biggest Estonian exercise to date, but it was also the first time the whole brigade took to the field to practice as a coherent unit, the first time the artillery battalion fired all their guns as a unit, and the exercise ended with the first time the whole brigade stood at attention together in a magnificent lõpurivistus (literally “finishing alignment”). To these can now be added today’s snap drill, specifically meant to test the ability of the army to respond swiftly to the emergence of a new threat (something one can’t help but feel would be a sorely needed exercise in Finland as well).

While Tallinn might be worried about their eastern neighbour, they are certainly not going to just lay flat in the hope of not provoking the bear. Instead, they are doing the best they can to plug the holes identified in the capabilities of their armed forces. The fact that certain key capabilities, such as air policing, are provided by NATO, means that they seem to be doing quite well with the limited resources they can muster with 2% of the GDP.

The next time anyone tries, Estonia is determined to not give in without a fight.

MTA 2020 – Bigger Hulls and Added Capabilities

While the growth in size from the current fast attack craft to the upcoming MTA 2020 has been noted by many, there seems to be a lack of appreciation for the added possibilities that comes with this.


Currently, the two Finnish classes of fast attack crafts have different secondary roles, where the Rauma-class has the possibility to equip a towed array for hunting submarines, and the Hamina-class sports (a very limited number of) Umkhonto surface-to-air missiles. In practice, this means that any task force, either a pure naval squadron or one escorting a convoy of merchant shipping, will have to feature at least one vessel from each class in order to have even a theoretical capability of meeting both threats. However, even in that case, the possibility of offering any kind of mutual protection remains limited, as the Rauma-class preferably would have to scout in front of the task force to be able to notice submarines laying in ambush (and this means a distance measured in kilometres to get a noise-free environment for its towed array), while the rather limited 12 km range of the Umkhonto means that any venturing subhunter or larger convoy will have an air defence cover only in their immediate vicinity. The limited number of missiles also means that it is entirely possible for a single Hamina to expand all its missiles trying to fend off just one or two airstrikes, after which the sole air defence weapon left is the 57 mm Bofors gun with proximity or time fused shells.

In practice, at least two vessels with Umkhontos are needed to provide any sort of air defence umbrella, either Hamina-class FAC’s or the far larger Hämeenmaa-class minelayers which also feature a similar eight-round launcher. This is both due to the low number of missiles and to get better coverage. This means that we would need to employ a third of all vessels featuring air defence capability for any given task force. A similar situation arises in the case of the ASW-capable Rauma-class.

The bottom line is that currently the Finnish Navy can’t be expected create more than two effective task forces at any given time, and even then, their effective endurance in combat will be limited by the relatively small supply of on-board weapons. Their ability to stay at sea for any prolonged time (i.e. longer than a few days) is also limited due to the small size of the crews. The fast attack craft also lack the capability to operate in ice, which is a significant drawback given the fact that the sea is often frozen over for at least four months each year.

Squadron 2020

It is to remedy these deficits that the new Laivue 2020 (Finnish for Sqaudron 2020) will be made up of corvettes, and not fast attack craft. This is a shift in a long-standing tradition of employing light vessels to deliver shoot-and-scoot style attacks on enemy fleets, but also gives the Finnish Navy serious new capabilities that will heighten the total effect of not only the navy, but the Finnish Defence Forces as a whole.

To begin with, the employment of larger steel hulls, gives the ability to operate a serious naval task force in ice for the first time in decades. This in itself is a major shift, though not necessarily a game changer, as it can be assumed that enemy fleet movements will also be drastically reduced during the winter.

Of far greater importance is the fact that the navy can now create a task force also for mission that require extended stays at sea, such as escorting friendly shipping or hunting submarines further out at in the Baltic Sea (currently, the Finnish ASW-strategy is that our chains of underwater listening posts will detect any intruders, after which our units on call will rush to the scene and either drive away the intruder or sink it), before they can take up positions outside of our main ports. While it is easy to dismiss the need for extended operations with the swift nature of most newer conventional wars, such as Georgia and Crimea, the capability could come in handy in prolonged times of heightened tensions, where solid intelligence is a must for the political decision makers. This endurance is heavily tied to having larger crews, as well as larger supplies of fuel, food, munitions, and other basic goods.

VLS – The Big Deal

The upgraded armament is of huge importance. The numbers below is based on the concept shown to the general public at last week’s press release, and is to be taken as an early draft (this is emphasized by the Navy). Still, while the details of the armament can and probably will differ when the vessels are launched, the general capability will probably be as shown.

The number of anti-shipping missiles is set double compared to the Hamina and Rauma-classes, which gives some added tactical opportunities. Also, while the thought of hunting submarines with depth charges and rockets/mortars is optimistic at best and suicidal at worst, the likely reintroduction of torpedoes into the arsenal of the navy would provide a much needed boost to the Finnish anti-submarine capability. However, most importantly, the vessels are set to feature a vertical launch system, VLS, in the bow.

The VLS-system in the picture seems to be around 4-5 meter in width and around 2-3 meters in length. This corresponds to two Sylver VLS-cells. The Sylver VLS is a French system, in use with a number of navies around the world. The basic layout is that each cell consists of eight tubes, and is available in four different lengths. The lengths provide rooms for progressively longer (obviously) and more complex missiles, so that while the shortest Sylver A35 only holds “traditional” short- to medium-range surface-to-air missiles, the full-length A70 already offers land-attack capability through the SCALP N and BGM-109 Tomahawk cruise missiles. The A70 is however too large for a corvette, and I have a hard time seeing cruise missiles being a priority for the navy (especially as some modern anti-shipping missiles, such as the Saab RBS15 Mk III, has a secondary land-attack capability). The interesting versions are the midsize A43 and A50, which provide the ability to employ the Aster 15 and Aster 30 (A50 only).

The Aster missile has been offered to the Finnish Defence Forces before. Some ten years ago, the Finnish Army sought a new surface-to-air missile to replace the Buk. Eventually, the NASAMS II was chosen, with the runner up being the SAMP/T-system (fr. Sol-Air Moyenne Portée Terrestre), featuring the Aster missile mounted on a transporter erector launcher coupled with a mobile Arabel-radar and assorted control and guidance systems. Unlike the NASAMS, the Aster 30 provides the ability to intercept and destroy ballistic missiles such as the (in)famous Iskander, and then Chief of Defence Admiral Juhani Kaskeala was clear about the reasoning behind the choice of NASAMS over Aster:

“Instead of one Cadillac, we bought 4 Volvos. Now we are getting more missiles than with the other option.”

The NASAMS is a very good medium-ranged system, and the increased number of batteries compared to the SAMP/T was very much needed for a country the size of Finland. Still, the fact that Finland completely lacks any kind of even theoretical defence against ballistic missiles left something of a bad taste. With the announcement by Rear Admiral Takanen that Laivue 2020 will be able to provide area defence with the use of their surface-to-air missiles, one can ask if the defence forces are about to get the highly anticipated anti-ballistic missile capability after all? The modular nature of the Sylver means that with a “small” extra cost, the flexibility of the system increases drastically. A brief recollection of the missiles available to the Sylver:

The A35 can employ the following missiles:

  • VT1: French IR-seeking short-range missile for self-defence. The corresponding ground-based version of the Crotale missile is in use with the Finnish Army (ITO90M), so would provide some degree of commonality (although it can be discussed if it gives any synergy effects worth mentioning). The unique aspect of the VT1 is that no less than four missiles can be crammed into a single Sylver launching tube, providing ample supply of close-range missiles,
  • Umkhonto: South African IR-seeking short-range missile for self-defence (a radar-guided version with slightly longer range is also available). In use with the Finnish Navy as ITO04,
  • CAMM: IR-seeking short-range missile for self-defence, based on the British ASRAAM air-to-air missile,
  • MICA: The MICA is a medium-range missile with an active-radar seeker. In its air-to-air versions it is performing much the same role on the Rafale and Mirage 2000 as the AMRAAM is on our Hornets.

In addition to the above, the A35 can employ:

  • Aster 15: An advanced medium-range missile, providing local area defence at somewhat longer ranges than the MICA.

In addition to the above, the A50 can employ:

  • Aster 30: Similar to the Aster 15, but featuring a much larger booster, providing longer range and an anti-ballistic missile capability. The capabilities of the Aster 30 is currently being expanded upon through the new Block 1NT and Block 2 missiles, which will provide significantly better anti-ballistic missile performance.

In addition to the above, the A70 can employ:

  • SM-2ER Block IV: The Standard Missile-2 Extended Range is an American long-range surface-to-air missile, which also has a terminal phase ballistic missile defence and secondary anti-shipping ability,
  • SCALP N: The SCALP N is a ship-launched cruise missile for attacking ground targets at long (over 1,000 km) range. It is based on the air-launched Storm Shadow/SCALP,
  • TLAM: The Tomahawk Land Attack Missile is a US ship-launched cruise missile for attacking ground targets at long (over 1,000 km) range.

The nice thing with a VLS-system like Sylver, or the larger US Mk 41 VLS for that matter, are their versatility. When traditional launchers have often been weapon specific, leaving little room for variety based on tactical needs, the loadout of the VLS-cells can be tailored to suite the expected threat scenario of individual missions. And if Laivue 2020 get (even a limited) anti-ballistic missile capability, this would plug what is perhaps the largest single capability gap in the current order of battle of the Finnish Defence Forces. As said, the A70 is likely out of reach for a vessel this size (though one should never underestimate the Navy that put four 10’’ guns on a 3,900 ton ship), but the A50 just might fit in.




With that said, it would certainly be great if suddenly an additional billion appeared, that we could replace the ships on a 1:1 basis…

Ocean X Team and the Midget Submarine that wasn’t

The mysterious submarine found inside Swedish waters this week (27.07) has turned out to be the Imperial Russian submarine Som, lead ship of its class. The vessel sank in a collision with the Swedish steamer Ångermanland (also reported incorrectly as being named Ingermanland). In a bizarre twist of fate, Ångermanland was coming from the port of Mäntyluoto, Pori, in what was at the time the Russian Grand Duchy of Finland, carrying packages for Russian POW’s held in Germany. The Som was originally laid down as the Fulton by the legendary Electric Boat Company, and served as the prototype for one of the US Navy’s first submarine classes, the Plunger-class, . The details of the sinking have been known [1, 2, 3], but the exact location of the wreck has so far not been determined.

During the first few hours after the find was publicised there was a host of speculation about the location, origin, and age of the wreck. This was largely created by the fact that the Ocean X Team gave very limited info to media:

The submarine looked “modern”, but could be from the 80’s, it was found roughly 1.5 nautical miles (2.75 km) from the coast, clearly inside Swedish waters, and the hatches were closed. No to very little damage was visible externally. The vessel was roughly 20 meters in length, and around 3 meters wide. And there were what looked like Cyrillic signs on the wreck.

Added to this, a small amount of video clips were released, without any comments regarding which part of the hull was in picture at any given moment. A single multibeam sonar picture of the wreck in its entirety was also released.

All in all, the original picture given was that the submarine was a midget submarine, dating from the time of the great Swedish subhunts, or newer. This, coupled with the Cyrillic lettering, made the wreck politically sensitive.

However, things soon started to fall apart for Ocean X Team.

Age, identity, and origin

Submarine designs have varied greatly over the 100+ years they have been in active service. The early submarines had usually a somewhat cigar-shaped hull, with the conning towers being either completly absent or very low (the terms ‘sail’ and ‘conning tower’ are often used interchangeably in English, although this is technically incorrect). The leading designer of this time was John P. Holland of the abovementioned Electric Boat Company, which either directly through exported designs or indirectly by influencing other designers set the pattern for these early vessels. Som is an example of the former, with Hajen, Sweden’s first submarine, is an example of the latter. Hajen was designed and built in Sweden, but clearly patterned after Holland’s designs. It currently resides as a museum ship in Marinmuseum in Karlskrona.

In the years leading up to and during the WWI, the hull form started to evolve, with the top of the hull becoming flatter and the bow and stern becoming more ‘shiplike’, first with straight plumb bows, and later with different kinds of raked or angled bows. The submarines started growing larger, and the sails became higher and more pronounced. The large amounts of railings used on the early designs started to be replaced by removable railings mainly used when the vessels lay at anchor. Welding also started to be used more and more instead of traditional rivets, until eventually the submarines became of all-welded construction in the years leading up to WWII. These boats, optimised for performance on the surface, would reach their climax in the early 40’s. The classic German U-boats of the Type VII and Type IX classes belong to this group.

During the war and in the immediate post-war period, advances in propulsion for submarines, and in search radars for the submarine’s adversaries, meant that the focus shifted from surface to sub-surface operations. As such, the hull forms started to shift yet again, with the decks becoming smaller (relative to the hull size), and everything started to become rounded to lower drag and avoid turbulences. All kinds of fixed railings disappeared.

As a general rule of thumb, midget submarines (which started to appear during WWII) have followed roughly the same pattern as the conventional submarines, but are smaller.

In other words, in the same way as a car-enthusiast finding the remains of a rusted car in a backyard would have no problem in telling whether it’s a fifties American muscle car or an eighties Japanese compact, no one with even a basic knowledge of submarines should have any problem with determining the wreck of a Holland-type submarine such as Som from that of a post-WWII midget submarine. Especially if the hull is “largely intact and not showing any signs of damage”.

With regards to the lack of vegetation and sediments, several people, most notably Ola Oskarsson, noted that more or less all wrecks in the Baltic Sea that are found at depths deeper than 40 meters shows very little growth or sediments, and as such this is not an indication that the wreck is new. Who is Ola Oskarsson then? He’s the founder, member of the board, and Market Developer of MMT, a Swedish diving and sea survey company that has found numerous wrecks, including submarines of varying age and the Swedish Air Force DC-3 downed by Soviet fighters in the fifties (however, unlike Ocean X Team, MMT have never found an UFO…).

Within hours of the discovery it was soon clear that the most likely candidate for the wreck was Som. It was one of relatively few submarine-classes ever built to measure around 20 meters in length (Som having an LOA of 19.3 m), with even WWI submarines often measuring 30 meters and above, and midget submarines usually (to the extent that one can generalise a midget submarine) being 10-15 meters in length. Several details also matched, and the Som was supposed to have sunk in Swedish waters west of the Åland Islands. As it was a Tsarist-submarine, the pre-1918 spelling, “Сомъ”, would also have included the hard sign ‘Ъ’, which was visible in the videos released from the wreck.

The scam is revealed

The really interesting part was when it started to become clear that Ocean X Team had deliberately been searching for the Som for at least a year.

In July 2014, Peter Lindberg (confirmed to be the same Peter Lindberg that’s part of Ocean X Team through cross-matching e-mail addresses used) asked for details about the fate of Som, and received the general story and the location of the wreck “between SwartklubbenArholma”. In both Finnish and Danish news, iXplorer Ocean Research, the Russian/Icelandic team that was revealed to have been the source which found the coordinates in a Russian archive before handing them to Ocean X Team, confirmed that they had been looking for the Som:

“We’ve been looking for it for about two years now. Ocean X Team is one of the companies we have been working quite a lot with.”

Did Ocean X Team know that it was the Som you were looking for?

“Maybe some in our team decided to conspire a bit, I don’t know why. Anyway, it is clear that this is a Russian vessel, but it is far from being a modern one.”

Alexey Mikhailov (aka “Max Rite”) in Helsingin Sanomat

Of added interest was the fact that the videos shown had the date stamp 15.07, i.e. the Ocean X Team had twelve days to shift through the material before presenting it to media. Note that while we do not know the full scope of the material available to Ocean X Team, it is most probably far longer than the short second clip shown publicly, and includes video of the nameplate.

Ocean X Team’s response when faced with the allegations that they had knowingly concealed the age and identity of the submarine to get added publicity, was to state that they thought Som would be “much further south”, that they haven’t been able to compare the sail with any pictures to be certain of the ID of the class (the Som had an extensive rebuild in 1914, and there are apparently no detailed drawings of the final outcome), that the picture of the nameplate found by Peter Krantz had evaded them (a fact Lindberg admitted was “embarrassing”), and that they had received “very limited information” from iXplorer.

Peter Lindberg is trying to tell us that a professional team with years of experience diving in the Baltic Sea:

  • Didn’t know about the special conditions in the Baltic Sea that preserves old wrecks really well,
  • Were so sure of the reported position of where the Som went down, that they, despite the relatively primitive navigational aids found on board a coastal steamer in 1916, didn’t even consider the possibility it could be wrong,
  • That Ocean X Team during almost two weeks of analysing the material and comparing it to their research, wasn’t able to come up with a plausible ID of the wreck,
  • That the above is true despite them capturing the nameplate of the ship on film,
  • That iXplorer is lying when they affirm that Ocean X Team knew that the coordinates sent should lead to Som,
  • That when they themselves were unable to confirm what wreck they had found, they didn’t ask iXplorer what they thought the coordinates should lead to,
  • That they did not find it odd that the the damage of the wreck (some “pipes” in the sail being bent, the vessel otherwise looking intact) exactly matched the damage Som suffered according to the master of S/S Ångermanland (“[T]he submarine [probably] received a light push, damaging the periscope, but not the vessel itself”, article in DN 24.05.1916, found by historian Lars Gyllenhaal),
  • That they were not able to distinguish the classic lines of a Holland-type vessel from a modern midget submarine despite the team having researched the Som for at least a year and having twelve days to go through the pictures of the wreck,
  • Despite knowing there was a submarine confirmed to have sunk in the general area, they still found it more likely that the wreck was from an unknown “modern” midget submarine, even when there were no indication that any midget submarine would have sunk in the area,
  • And finally, they didn’t even care to mention the Som in the opening speculations, despite it fitting the description of the wreck on numerous points.

Except for the point about iXplorer lying about whether or not they had forwarded the info that the coordinates given should lead to Som, I find all of the bullet points above highly questionable. I am no diver, but I find wreck hunting extremely interesting, and have a general picture of how this is usually conducted. Any diver looking for a wreck will tell you that the lion’s share of the work is the background research, spending hours and hours in archives and scanning old newspapers and official reports. This also seems to be the case here, with at least a year, probably more, of background work going into this project before the wreck was actually found. That they during this year would have missed such basic facts as the name Som being spelled with a hard sign, or the general shape of a Holland-class submarine, means that the Ocean X Team is either sloppy, incompetent, or lying. In light of their earlier successes, I find the first two rather unlikely.

A far more likely explanation than ineptitude is that the whole thing is a PR-stunt made to bring publicity and hard cash to the team, something that is supported by the poor financial state of the company. The sums taken for publishing the material might also be of interest: 10 seconds of video goes for 35,000 SEK (~3 700 EUR), while still pictures go for 10,000 SEK (1 055 EUR) a piece according to DR.


Much has been made about the Russian connections, and how the borderline hysteria the initial reports created has been used by Russian state-controlled media to discredit the Swedish subhunt which last year was able to confirm foreign underwater activity deep inside Swedish waters.

Still, to say that Ocean X Team is on Putin’s payroll is to jump to conclusions. It may well be that the idea of presenting the find as a potential modern-day intruder stemmed from Russia, and was proposed to Ocean X Team by iXplorer as a great way (or so it seemed at the time) to get more publicity out of an otherwise very niched find. If this is the case, one can safely assume that Ocean X Team believed iXplorer would support the story, and not throw them under the bus at first opportunity. It may also be that the idea came from Ocean X Team themselves, and that Russian state propaganda simply decided to take advantage of the opportunity.

Wherever the idea originated, it was ruthlessly used by the Kremlin for their own purposes. I find it entirely possible that Mikhailov, having served as a diver in the Russian Northern Fleet, was sincere in wanting to find the submarine and the last resting place of his brothers in arms, and that either he or someone closer to one of Kremlin’s intelligence agencies somewhere along the way realised that the project could also provide an opportunity for a propaganda coup as well. This would be supported by the time scale: we know that Ocean X Team, and presumably iXplorer as well, has worked on finding Som at least for a year, probably longer. The need for a submarine-based propaganda story aimed at Sweden was far smaller/non-existent last July, not to mention two years ago in the pre-Crimean age of European security.

At this point, the best Ocean X Team could do is probably to come clean, admit they tried to enlarge the public interest in the story by leaving out certain details, and apologies to the media, the public, and the experts they misled. Admitting to having been outsmarted by iXplorer might hurt, but trying to stick with a story that’s basically telling the world that they don’t know how/didn’t care to do proper research will probably hurt even more in the long run. Naturally, if there have been undeclared money transfers involved as some has hinted at, coming out might not be possible unless they are prepared to have a talk with the Swedish tax agency (bad case) or SÄPO (worse case).

…And on a lighter note, it seems Finnish media has greater trust in the amazing powers of crowd-source information gathering than Swedish 😉
