Norway's new Type 212CD diesel-electric submarines (SSKs) will introduce air-independent propulsion (AIP) to the Royal Norwegian Navy (RNoN), significantly enhancing its underwater capabilities. This advancement is expected to be a game-changer, as stated by the commanding officer (CO) of one of Norway's current in-service boats.
Currently, the RNoN operates six Type 210 Ula-class SSKs, which are set to be replaced by up to six Type 212CD submarines, with the first delivery slated for 2029 and subsequent deliveries extending into the mid-2030s. These new submarines are being developed through a strategic collaboration with Germany, initiated in 2017, marking the beginning of a broader defense partnership formalized in 2023.
Originally, the RNoN planned to replace the Ula-class boats with four Type 212CDs. However, rising regional security concerns and underwater challenges led Norway’s Chief of Defence, General Eirik Kristoffersen, to advocate for six new submarines. In April 2024, the Norwegian government proposed to parliament the acquisition of at least five new submarines as part of a long-term defense strategy extending to 2036.
The Type 212CD submarines will bring crucial new capabilities to the RNoN, particularly through AIP technology. The CO of the Ula-class boat HNoMS Utvaer emphasized that AIP is a significant game-changer. Unlike the current Ulas, the Type 212CD’s fuel-cell AIP will reduce the need for ‘snorting’ at periscope depth, a noisy and visible process that increases vulnerability to various threats.
This capability is demonstrated by the Royal Swedish Navy’s Gotland-class SSKs, which utilize a Stirling fuel-cell AIP system, allowing them to remain submerged without snorting for several weeks. The introduction of AIP aligns with the RNoN's focus on enhancing stealth and operational capability in its challenging regional waters.
In addition to AIP, the Type 212CDs will allow the RNoN to explore new capabilities such as strike capabilities with the Kongsberg Naval Strike Missile (NSM). The Ula-class boats, although not equipped with strike capabilities, remain formidable with up to 14 weapons and advanced torpedoes like the Atlas Elektronik DM2A3 Sea Hake.
Despite their age, the Ula-class submarines maintain high operational effectiveness through regular upgrades and maintenance. This includes new sonars, command and information control consoles, and advanced navigation equipment. The CO of Utvaer praised the robust maintenance process, which ensures high material readiness and prolongs the operational life of the submarines.
The continuous upgrade and maintenance efforts reflect the RNoN's commitment to maintaining a capable and ready submarine fleet, even as they age. This dedication ensures that the Ula-class boats remain potent platforms until the new Type 212CD submarines are fully integrated into the fleet.
