Finland goes GBAD-shopping

In a long-awaited move, the Finnish Defence Forces Logistics Command yesterday sent out the RFQ for a new ground-based air defence system “with a high ceiling”. The corresponding RFI went out in 2018, and under the current schedule the procurement will be finalised before the end of 2022 and the system will become operational during the latter half of the 20’s.

For a more general overview of the current state of the Finnish high-end ground based air defences (and why we won’t acquire an anti-ballistic missile capability), I recommend that you check out my sub-chapter on Finland in the FOI anthology “Beyond Bursting Bubbles“, but the long story short is that Finland acquired the Buk-M1 in the late 1990’s as part of a deal to cover the Russian debt stemming from the Soviet clearing accounts. Unfortunately, worries about the ability of Russia to counter the system meant that they had to be retired quite soon thereafter, with the last conscripts training on the system in 2005. Exactly when (if?) the system was withdrawn is unclear, but it seems to have survived in (limited?) service past Crimea.

In any case, a replacement system was acquired under what would become the ITO12 procurement, which saw SAMP/T and NASAMS II face off in a competition won by the NASAMS. The reason behind the choice was bluntly described by then Chief of Defence, Admiral Kaskeala:

Do we buy one Cadillac or four Volvos?

In any case, the ‘Volvo’ has scored a number of successes around the world, and is generally seen as a potent system, but one that suffers from short range due to the poor performance of its AIM-120C AMRAAM missile when fired from a ground-based launcher. Janes lists it as having an estimated max range of 20 km, though this is partially offset by the launchers being able to be placed up to 25 km out from the fire direction centre (FDC). The ceiling is rather uncertain, with The Drive mentioning 50,000 feet (15,000+ meters), but on the other hand then-Finnish inspector of the ground-based air defences, colonel Sami-Antti Takamaa, in an interview in 2018 stated that the new system (which should be able to go significantly higher than NASAMS) should have a ceiling of 8,000 to 15,000 meters. There’s likely an apples-to-pears situation in the numbers above, with Takamaa referencing the effective engagement altitudes which are quite a bit below the theoretical maximum.

However, for most situations the maximum specifications isn’t as interesting as other factors. The ability to deploy the systems with the launchers dispersed, the active seeker of the missiles, modularity, and the modern C4I architecture are of greater value. However, the fact that the NASAMS would lose in top trumps against the system it replaced means that there is a gap above the coverage provided by Finnish SAMs, and one that can only be covered by fighters.

This leads us to the current ITSUKO-program, where throughout the focus has been on increasing the air defence capabilities at high altitude. This is interesting, as most countries discuss their different classes of SAM’s in terms of range rather than ceiling, and clearly shows which operational problem the FDF is trying to solve. Obviously, with increased ceiling comes increased range (though one shouldn’t think of the effective engagement zone as a half-sphere above ground, as the routes chosen by modern missiles and the physics involved makes things a bit more complex than that), but this is largely seen as a secondary bonus. In the earlier quoted article, major general (engineering) Kari Renko of the Finnish Defence Forces Logistics Command explained that “Increased territorial coverage means that we have more batteries operational”, and struck down the notion that a meaningful increase in territorial coverage could be achieved solely by increasing the range. In effect, this is due to the large area of Finland, which means that the difference in coverage between differently ranged systems, especially at low range, is small enough that it is negligible at the operational or strategic level.

Here it is good to remember that as none of the current systems are to be replaced, the number of operational batteries will in fact go up. This in turn means that, in the words of current inspector of the ground-based air defences, colonel Mikko Mäntynen, the “fighters will get a higher degree of freedom”. While this is all good and true, there is a nagging feeling that this might be an attempt to cover for the fact that HX won’t reach 64 fighters. Let’s hope that feeling is unfounded…

The news yesterday was that the field competing has been cut down by half. Of the ten companies that received the RFI in 2018, five are still in the competition bidding for the role as prime contractors. These are Kongsberg Defence and Aerospace (KDA), Diehl Defence, MBDA, Rafael, and IAI. Missing from the list are all American companies, as well as Swedish defence company Saab whose RBS 23 lacks the punch to compete in this race (note though that Janes gives the max altitude as 15,000 meters, again showing that 15,000 meters max doesn’t necessarily mean that your system can effectively handle engagements at 8,000 to 15,000 meters). However, it is entirely possible that Saab appears as a subcontractor in some of the bids, as their Giraffe 4A radar has had a tendency to do so in other places. Raytheon is a long-term active partner to KDA, and it is no surprise that they are confirmed to be working together with them here as well (even if rumours had hinted at them also bidding separately as a prime, presumably with the MIM-104 Patriot). Another of Raytheon’s joint programs might also show up…

Of those bidding, Diehl is without doubt the odd one out. As far as I am aware of, Diehl has nothing bigger than the IRIS-T SLS (which recently entered Swedish service as the RBS 98). Being based on a short-range IIR air-to-air missile, it suffers from a 5,000 meter ceiling (again according to Janes), leaving it even shorter-legged than the NASAMS. To be completely honest, I have no idea about what Diehl is planning to offer.

Edit 30 October: Diehl in fact has a longer-ranged version. There is quite a bit of confusion in their designations in open sources (I’ve e.g. seen SL, SLS, and SLM all refer to just different launchers firing the same IRIS-T missile, and I’ve even seen the Swedish EldE 98 referred to as SLM!). However, Diehl’s SLM is in fact a rather different missile with a seriously longer range thanks to a larger rocket and an aerodynamic nosecone that pops off once the target is within range of the missile’s IIR-seeker. This dual-mode (firing solution and early tracking being provided by radar and datalink until switching to final guidance by IIR) is rather interesting and could potentially be more difficult to spoof compared to more traditional solutions. The missile has been test-fired successfully, but the operational status seems to be rather uncertain. Thanks to f-pole for clearing things up!

KDA is the obvious favourite, being able to offer the AMRAAM-ER for the NASAMS-system. The AMRAAM-ER in essence combine booster of the ESSM and the front unit of the AMRAAM to produce a completely new missile with “50% increase in range and a 70% increase in altitude” compared to the current AIM-120C-7.

In other words, KDA can simply offer more of a system already in service with the Finnish Army, but with ability to use either the shorter-legged AMRAAM or the longer-legged AMRAAM-ER according to need. The modularity of the NASAMS also means that integrating a host of other missiles is possible, should the FDF be so inclined (spoiler alert: they’re probably not). That kind of synergy effects could very well be hard to beat, but the competition isn’t giving up without a fight.

As noted earlier on the blog, MBDA has had a surprisingly difficult time in landing any major contract with the FDF. The obvious system for them to offer is the Land Ceptor/CAMM-ER. The missile is an operational system with the British Army and the specifications on paper seems to be a good match, but it is difficult to see it outmatching the stiff competition.

The question about what the two Israeli companies will offer is more open. Rafael is able to offer the SPYDER, which is a truck running around with a bunch of missiles on its back. It offers the ability to fire both the Python 5 highly-manoeuvrable short-range IIR-missile, but also the Derby longer-ranged missile. The overall concept is rather similar to that of the NASAMS, with a modern C4I architecture and air-to-air missiles adopted for ground-based use, and while not as prolific as the NASAMS it has scored a few export successes from serious customers such as Singapore. However, most numbers found in open sources seem to indicate that the SPYDER lacks the range and ceiling to be able to offer a meaningful improvement over the current NASAMS. This would in turn mean that the system offered is the David’s Sling, which uses a two-stage Stunner-missile (also known as the SkyCeptor). The missile is perhaps best known internationally as the PAAC-4 missile for the US Patriot-system, which is a joint program between Rafael and Raytheon to produce a significantly cheaper missile with better performance compared to the current PAC-3 that is used for anti-ballistic missile work with the Patriot battery. The Stunner is designed from the outset to be able to easily integrate into other systems, meaning that it is possible that the weapon could communicate better than some of the competition with the current systems found in the Finnish integrated air defence network. Still, it does feel that the ABM-capable is a bit of overkill in a competition against missiles such AMRAAM-ER and CAMM-ER (remember that several high-ranking officials and generals at different times have shot down the idea that Finland would be interesting in pursuing a real ABM-capability), unless the offer really is one we can’t refuse.

IAI has a more varied, and at least on paper, more suitable range of weapons, with the BARAK-series being the logical contender. This include a range of missiles, with the BARAK-LRAD missile being the most likely version on offer here. This is part of the general BARAK MX-system, and is developed in parallel with the BARAK 8 for the Indian Navy. Crucially, IAI’s Elta-division has a large portfolio of radars (including the ELM-2311 C-MMR which was recently acquired by the FDF for use as a counter-battery radar), and as such it would be interesting to see which radars they would pair with their interceptor for the bid.
