Type 212CD submarine

A €5.5 billion contract for development and procurement of the six submarines was placed with TKMS on 8 July 2021 after the German and Norwegian governments reached an agreement in principle in March. This followed an extensive period of negotiation between industry and the two governments which took place after Norway had, in 2017, decided on an extensive naval partnership with Germany and TKMS for their replacement project. The Ula-class submarines were also built by TKMS/HDW. In Kiel, a German-Norwegian Building Program Office (BPO) is to be set up and tasked with representing the two states in matters of design, construction and acceptance. Management will alternate between a German and Norwegian representative, with a third of the staff being Norwegian. Afterwards, a Lifetime Management Program Office (LMPO) is to be established in Haakonsvern Naval Base. Management will also alternate, with a third of the staff being German. The office is to handle questions concerning maintenance and repairs of the submarines. Norway will establish maintenance facilities for both countries submarines. According to the Norwegian Armed Forces Long-Term Plan adopted by the Norwegian Parliament on June 4, 2024, Norway will purchase two more submarines in addition to the four submarines already ordered from Germany. Norwegian and German U212CD (Common Design) submarines are to be based together in Southern Norway. A Norwegian Ministry of Defence official told Janes on 7 June 2024 that a new base for the U212CD, including infrastructure, would be built at Haakonsvern, where Norway's current Ula-class submarines are already based. The new infrastructure will include pier, maintenance, and test facilities for the U212CD. Critical design review In August 2024, the Norwegian Ministry of Defence announced having completed the design review of the Type 212CD programme. As a result of completing the Critical Design Review (CDR), the production of the submarines will be intensified. ==Submarine design==

The submarines will be based on, but nearly twice the size of the current Type 212A class and features a new stealth design—the hull will be diamond-shaped to deflect emissions by the active sonars common on modern anti-submarine warfare (ASW) ships. Propulsion Just like the Type 212A, the submarines will be fitted with a hydrogen fuel cell-based air-independent propulsion system, although they will receive two (MTU 4000 series) diesel engines instead of one. The overall endurance is to be increased as well. Command and control systems The first batch of German Type 212A uses the MSI-90U Mk 2 CMS combat system which was developed by Kongsberg. A new combat system ("ORCCA") to be developed by kta naval systems, a joint venture between TKMS' naval electronics division Atlas Elektronik and Norwegian manufacturer Kongsberg will be installed on the boats and is claimed to allow the analysis of larger amounts of sensor data as well as to improve interoperability with allied forces. The contract was signed in December 2025 (NOK 3.5 billion / €291.8 million). Sensors Two photonics masts including sensors from Hensoldt (OMS 150 and OMS 300) will be used instead of the hull-penetrating periscope of the previous U212A class for search, surveillance and attack functions. A Hensoldt panoramic surveillance system will be installed while Kongsberg will contribute the active SA9510S MKII Mine Avoidance and Navigation Sonar as well as echo sounders for navigation. Weapons The submarines will feature four tubes for DM2A5 heavyweight torpedoes and Germany plans to fit the IDAS air-defense missile to theirs. In December 2024 it was reported that the Bundestag passed funding for the submarine launched version of the IDAS Missile. ==List of boats==

Future operators ; (6) : 2 boats to be delivered in 2032 and 2034. The contract was signed in July 2021. The submarines are to be delivered from 2029 to 2035. : In June 2023, the Norwegian Defence Chief recommended to increase the order to 6. In December 2025, the government made the decision to purchase the 2 additional submarines. The purchase was approved by the parliament in January 2026 and the contract was signed. In July 2024, Canada publicly unveiled its plan for the future of its navy, which includes up to 12 submarines. On August 26, 2025 the Type 212CD was shortlisted alongside the KSS-III Batch-II as the only qualified options under the Canadian Patrol Submarine Project. In March 2026, Norway and Germany submitted a joint government-to-government offer to Canada for participation in the submarine programme. : Several agreements were signed with Canadian industries to localise the production, and include: :* Seaspan Shipyards signed a teaming agreement with TKMS to get a sovereign capability for the sustainement and through-life support of naval ships. :* Magellan signed an agreement for the production of heavy torpedoes and their maintenance, and participates in the development and production of anti-torpedo torpedoes. :* Strategic Teaming Agreement signed with EllisDon related to long-term infrastructure to support the CPSP. :* TKMS signed agreements related to indigenous Canadians developments with: :** Songhees Development Corporation, Des Nedhe Group Defence and Glooscap Ventures, :** Inuit Development Corporation Association ; (3 additional) :According to the Zielbild Marine 2035+ plan, the German will operate from 6 to 9 Type 212 CD, and it includes the successors to the Type 212A, which would mean up to 3 additional Type 212 CD to be ordered. Failed bids ; : The Type 212CD was in competition with the pair Saab Kockums / Damen with a Blekinge derivative submarine and with Naval Group who proposed the Orka-class. TKMS had offered an expeditionary variant of the Type 212CD submarine to the Netherlands; the Type 212CD E. This variant has a surface displacement of c. 3,100 tons and a submerged displacement of c. 3,450 tons. In addition, the boat has a length of more than 80 meters. ; :The Polish Navy planned to purchase 3 attack submarines as part of its Orka programme. The mentioned competitors include the A26 Blekinge, the KSS-III, the S-80, the Scorpene SSK, the U212 NFS and the Type 212CD. :Ultimately, the Polish Navy selected the A26 Blekinge in November 2025. == See also ==
