The DDS has announced a 180 million zark update for it's Caspian Sea and Barents Sea frigates (Terran Sea A & B types). The update, which is known as Terran Sea Update 2108A (TS2108UA) will take place early next 2108 and is intended to bring the frigates up closer to Arafura Sea standard. The ships will receive 360 CIWS and a number of system updates giving them full FIDO 1.0 capabilities and bringing them closer to Open Architecture 2.0.
The ships will be made ready to receive the 5036-A combat suite (though not actually to be fitted yet because of a lack of availability of the combat data management system and cost). The 4 Caspian Sea frigates may receive the suite in a further update in the Spring.
The ships will also be made ready for TPM-2 though the new missile launcher and handling systems will not be fitted at this stage. They will be able to datalink with the new missiles.
