Project history

A €5.5 billion contract for development and procurement of the six submarines was placed with TKMS in 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/

, 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. Construction of the first submarine is planned to begin in 2023.
