Saab to supply 9LV for Pohjanmaa-class

On April 9, 2019 By Corporal FriskIn Finland, Naval6 Comments

The Finnish MoD today announced that they have shortlisted Saab as the preferred supplier for the combat management system, CMS, for the upcoming Pohjanmaa-class of corvettes. This does not only mean that Saab’s 9LV CMS will be at the heart of the vessel class, but also that Saab will be the main supplier and integrator of the naval systems of the vessels.

Due to Finnish internal politics the contract for the system won’t be signed just yet. As a political stunt, the outgoing prime minister Juha Sipilä dissolved the government shortly before the Finnish parliamentary elections. While the ministers stayed on as caretakers up until the elections held later this week, the main shipbuilding contract as well as the CMS contract were deemed too important to be handled by an acting minister of defence. As such, the formal contract will be signed only once Finland have a new government in place, which likely will take another month or two. However, the decision to name Saab as the preferred bidder after all three shortlisted candidates have made their best and final offers makes it highly unlikely that the decision to hand it to Saab would be overturned at the last moment.

The contract is a significant one from a Finnish point of view, with the total value likely to be in the range of hundreds of millions of Euros. Despite missing out on replacing the outgoing RBS 15SF (MTO 85M) anti-ship missiles, this further cements the position of Saab as the key systems supplier of the Finnish Navy. Not only will Pohjanmaa- and both FAC-classes have the 9LV once the Hamina-class have undergone their MLU, a number of sensors and other weapons have also been acquired from Saab. These include CEROS fire-control sensors, TP 47 light-weight torpedoes, and the Trackfire RWS which will be found on most Finnish surface combatants as well as auxiliaries.

Today’s press release doesn’t further elaborate on why Saab was chosen, but it is highly likely that the reasons mentioned by Saab when they discussed the offer last year eventually where the ones to seal the deal: Price, robustness, a “comprehensive industrial participation package”, “pretty advanced” capabilities when it comes to converting between national and international data links, and having a harmonised C3I system with both the Hamina-class as well as with the Swedish ships of the Swedish-Finnish Naval Task Group (SFNTG).

Saab will now get to integrate the main weapons systems, the Gabriel SSM, ESSM SAM, Bofors 57 mm guns, and the TP 47, as well as all the sensors and data links into a single working platform. Several of the sensors are still unconfirmed, but in accordance with earlier information it seems highly likely that the key sensor will be Saab’s Sea Giraffe 4A FF. This will be part of the SLIM (Saab Integrated Lightweight Mast), which will also feature ESSM equipment and a single rotating Sea Giraffe 1X. Operating on the X-band, the 1X has shorter range but better resolution compared to the S-band of the 4A. The SLIM will be delivered as a complete subassembly to the yard, which can then install it as a module. It is also likely that the vessels will be fitted with the Kongsberg ST2400 towed array for operations in the ASW-role*, as well as the Saab TactiCall integrated communications system.

The final look of the vessels is slowly taking shape, with only a few key pieces still unconfirmed. These include the length of the Mk 41 VLS tubes, though it seems likely they will be of the full ‘Strike Length’-versions, as well as the secondary gun system responsible for close defence against airborne threats and munitions as well as against smaller surface targets. It is probable that by the time we celebrate Navy Day in early July these last pieces of the puzzle will have been confirmed, and the building of the vessels can finally begin in earnest.

*I am working in another, unrelated, division at Kongsberg Maritime. However, all information regarding the ST2400 I have is from open sources. The guess is purely based on the fact that the ST2400 has been ordered for the Hamina MLU, and so far most new systems acquired for the Hamina MLU has also found their way to the Pohjanmaa-class.

9LV offered for Squadron 2020

On May 12, 2018 By Corporal FriskIn Finland, Naval6 Comments

1.2 billion Euros. That’s the quoted cost for Finland’s four new Pohjanmaa-class corvettes being built under the Squadron 2020-project. An estimate thrown around is that roughly half of that sum is the ship itself, and the other half is the naval specific items. While Rauma Marine Construction, RMC, has more or less secured the shipbuilding contract, the fight is still on for the “battle system”. This consists of the weapons, sensors, combat management system, and their integration into the vessel, and with a contract likely coming in at over half a billion Euros, it has certainly grabbed the attention of the shortlisted companies.

One of these is Saab (the other two being Atlas Elektronik GmbH and Lockheed Martin Canada Inc), and this means that I find myself together with a small group of Finnish journalists and their photographers in a nondescript conference room at Saab’s facilities in Järfälla just outside of Stockholm. The large site include a number of different production as well as R&D facilities, and everything is designated a protected site by the Swedish authorities, meaning that we have to pay close attention to what we are allowed to take pictures of. The reason is simple.

Things happen quite often, more than you know.

What exactly happens is left open to imagination, but it is clear that it includes both cyber security as well as people physically moving around in the vicinity of the site.

But if Saab isn’t too keen on discussing the details of attempts at intelligence gathering directed against them, they are very keen on discussing Finland. “It’s almost a home market for us”, senior director for Naval Combat Systems Mickael Hansson explains. “We are very proud of that as well” he says and points to the currently installed product base in the Finnish Navy. This covers everything from the Trackfire remote weapon system which the Navy has developed something of a love affair with (it has been bought for all three classes being built or undergoing MLU’s during the last years), via radars, remotely operated vehicles, communication systems, missiles, and on to the 9LV combat management system.

The 9LV is found in the Rauma-class, and soon in the Hamina as well as the system was chosen for the MLU. When asked what he believes were the deciding factors, Jonas Widerström, Saab’s Naval Sales Director Finland, mentions price, harmonisation with the Rauma-class, and above all the robustness of the system. Widerström should know, being a retired naval anti-aircraft officer having served aboard Swedish corvettes he has ample experience of the 9LV. Interestingly enough, the Hamina-class currently sports Atlas Elektronik’s ANCS 2000 but instead of upgrading this the Finnish Defence Forces chose to tear it out and replace it with Saab’s offering. While the Hamina MLU technically isn’t related to the Squadron 2020 CMS contract, it is clear that the MLU-contract means that Saab is the favourite for the larger deal as well. And Saab doesn’t beat around the bush when it comes to this.

We want to win this.

How is Saab then planning on doing this? The talking points comes as no surprise. They include a “comprehensive industrial participation package” and the value of having a harmonised C3I system with not only the Hamina-class but with the Swedish ships of the Swedish-Finnish Naval Task Group (SFNTG) as well. The 9LV is also sporting “pretty advanced” capabilities when it comes to converting between national and international data links and “very good sensor fusion software” with a rapid response time. Saab also points out that they have worked with the ESSM before on the Halifax-class (ironically as part of a team led by Lockheed Martin Canada), a system which “can be, maybe be on the SQ2020”.

To top off the offer Saab is bringing their own sensor suite. This is centered around the Saab Lightweight Integrated Mast (completely unironically abbreviated SLIM) which will be manufactured by Saab and delivered as a complete subassembly to the yard for installation aboard the ship. As a parenthesis, Saab explained that the renders showed this particular SLIM-setup “on another ship” and not on the Pohjanmaa-class. Hmm, I wonder what ship that could be…?

The mast sports a number of sensors and communication antennas, the most important of which are the vessels main active sensors: the Sea Giraffe 4A FF (Fixed Face) and a single rotating Sea Giraffe 1X found inside. Keen readers of the blog will remember that Saab originally planned for a setup with a single rotating 4A accompanying the rotating 1X, and while the head of marketing and sales for Surface Radar Solutions Pontus Djerf (another retired commander) maintain that it is an solution that’s “often good enough”, the fixed face version is more future proof and provides additional benefits. As the project has proceeded, this has led Saab to swap out the rotating 4A to the FF. The fixed 1 x 2 meter AESA-arrays cut response times, but it does not replace the need for the 1X. Instead the two complementing radars operate in S- and X-band respectively (in addition any CEROS FCS-systems would bring a K_u-band radar to the ship) which brings a certain amount of redundancy and jamming resistance while also providing radars optimised for slightly different roles. In short, the 4A looks at the larger picture, while the 1X has shorter range but better resolution. Notably both radars sport features borrowed from Saab’s work with artillery location radars and small targets (such as UAV’s), or C-RAM and ELSS respectively.

These are all interesting features for the Finnish Defence Forces, because as opposed to blue water fleets, the Finnish Navy is very much a force present on the right flank of the battlefield in any potential conflict. As such, the corvettes will play an important role in the grander picture (‘joint’ is a keyword for both the Squadron 2020 and the HX-programs) when it comes to establishing situational awareness and providing medium-ranged anti-aircraft support around the most populous areas of Finland. To be able to fill the needs of higher command, a serious sensor array of both active and passive systems coupled with an effective combat management system and the datalinks to share this information. Saab seems confident that they have the solution, and that they do so at a balanced cost/performance-ratio. We will have to wait for a few months and see if the Finnish Navy agrees.

Saab Bound for Naval Grand Slam?

On January 5, 2018January 6, 2018 By Corporal FriskIn Finland, Naval8 Comments

As the modernisation of the Finnish Navy’s surface fleet continues, Saab has managed to secure two key contracts. Earlier, it was announced that Saab would provide the new anti-submarine torpedoes set to be fielded by both the modernised Hamina-class FAC as well as the new Pohjanmaa-class corvettes (Squadron 2020). In many ways this was the low hanging fruit for Saab. Not only is development of their new torpedo well underway with Sweden as the launch customer, it is also based on proved technology in the form of the earlier Torped 45, making it possible to operate the older version from the installed tubes until the new Torped 47 is ready. Perhaps crucially, it is one of few weapons of its class designed with an eye to use in littoral and brackish waters, key features of the operating environment of the Finnish Navy.

This week Saab landed a bigger fish, as it was announced that they will provide the combat management system, fire-control system, integrated communication systems, as well as optronic sensors for the Hamina MLU. The odd bird out is the fact that the order include the CEROS 200 optronic sensor, which is already fitted to the vessels. Either these are worn out to the extent that buying newer is cheaper from a maintenance point of view, or there have been internal upgrades of the CEROS 200 since the original deliveries almost twenty years ago that have not been reflected in the name of the product, but are extensive enough to warrant buying complete units and not simply giving the CEROS its own MLU.

Another interesting inclusion is the Trackfire remote weapon station, with the Hamina now being the third class in the Finnish Navy to receive the RWS. The use of the Trackfire on the Hamina isn’t specified, but the wording in the press release does seem to indicate a single system per ship. As such, while it is possible that two stations per vessel will replace the port and starboard manually operated 12.7 mm NSV heavy machine guns mounted amidships, the likelier scenario is that they will take the place of the main armament. There has been talk (so far unconfirmed?) that the main 57 mm guns (Bofors Mk 3) of the Hamina vessels will be removed as weight saving measures and transferred to the four Pohjanmaa-class vessels, and this would fit right in. While the Trackfire is usually seen fitted with a heavy machine gun as the main armament, it is capable of holding “lightweight medium calibre cannons”, i.e. weapons up to and including low-pressure 30 mm ones. This is not an unheard of solution, with e.g. the Israeli Typhoon RWS being used with a number of the different Bushmaster-series of cannons as the main or secondary gun on a number of different naval vessels out there. A 30 mm Bushmaster, the Mk 44, is already found in Finnish service on the CV 9030 IFV, but before anyone gets too enthusiastic it should be noted that this uses a longer high-pressure round, so there is no synergy to be had. Instead, something like the M230LF, based on the chain gun found on the Apache helicopter, is the more likely candidate.

Dropping down in calibre from 57 to 30 mm is not necessarily a bad thing, as the main use of the weapon will likely be air defence and intercepting light craft. Modern 30 mm rounds will do quite some damage against soft targets such as warships as well, though naturally you won’t win a gun fight against a large vessel sporting a 3 or 5 inch gun anytime soon (to be fair, if you find your FAC up against a destroyer at gun range something has likely gone very wrong already at an earlier stage of the battle).

At the heart of the Hamina order is the 9LV, an open architecture system which allows integration of different sub-systems, sensors, and weapons into a single integrated package. As such, different building blocks can be integrated into CMS systems from other manufacturers, or other manufacturers’ subsystems can be integrated into the 9LV CMS. That Saab gets this kind of a complete deal including both the CMS, FCS, integrated communication systems, and part of the weaponry is significant, especially when looking towards the soon to be decided contract for a main systems integrator for the Pohjanmaa-class, a job which will likely be of significantly higher value than the Hamina MLU.

The main implications is that this makes Saab the front-runner for the Pohjanmaa-class CMS. Earlier the Rauma-class FAC received the 9LV during its MLU, and now on the Hamina 9LV is replacing Atlas Elektronik’s ANCS 2000-system. While the requirements for the CMS of the Hamina and the Pohjanmaa are not completely identical, there certainly is something to be said when the former replaces one of the shortlisted CMS’s with the another one, instead of simply upgrading it. It should also be remembered that several subsystems, including most weapons, will be the same for both vessels.

Yet another noteworthy development is that Saab recently announced a new fixed face version of their Sea Giraffe, in the form of the Sea Giraffe 4A FF. I have earlier questioned whether Saab’s twin rotating mast solution would satisfy the requirements of the Navy, and it seems clear that the 4A FF is a possible solution for the Pohjanmaa’s main long-distance sensor. As Saab is also well positioned to secure the order for the new PTO2020 surface-to-surface missile, they just might be on track to secure all major Finnish naval contracts they are bidding for.
