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.
