The CDR took place in Bergen and confirmed the technical viability of HENSOLDT's systems, validating the technical planning and execution of the upgrade process.

The modernization project, under a contract worth approximately €40 million, was signed with the Norwegian Defence Materiel Agency (NDMA) last October. The ULA class submarines, which were originally fitted with SERO 14/15 periscopes, are now set to receive cutting-edge HENSOLDT periscope and optronic mast systems. The upgrade will extend the operational lifespan of multiple submarines.

The Royal Norwegian Navy (RNoN) is in the midst of modernizing its submarine fleet, transitioning from the aging Ula-class to the more advanced Type 212CD, a product of German-Norwegian cooperation. This shift is driven by Norway's strategic need to maintain a robust undersea capability, especially given its proximity to the increasingly active Russian submarine fleet in the Arctic and the North Atlantic.

Currently, Norway operates six Ula-class submarines, which have been in service since the late 1980s. Despite their age, these diesel-electric submarines have undergone significant upgrades to their combat systems, sensors, and life-extension measures to remain operational until the new submarines are fully integrated. These upgrades will allow the Ula-class boats to continue service until the 2030s.

The future of Norway’s underwater forces lies with the Type 212CD submarines. The initial order, placed in 2021, consists of four submarines, with two more planned, bringing the total to six. The first submarine is expected to be delivered by 2029, with the entire fleet operational by the mid-2030s.

The 212CD class brings substantial advancements, including air-independent propulsion (AIP) systems, which allow for extended submerged operations, and enhanced stealth capabilities through a redesigned hull and quieter propulsion. These features will make the submarines significantly harder to detect, especially in Norway's operational waters, which are crucial for NATO's northern flank defense.
