Ula class submarines are a Norwegian military submersible design, stemming from a 1972 decision to modernize the submarine fleet of the Norwegian navy. The construction of the vessels was an international project: the combat systems were made in Norway, the attack sonar was from Germany, the flank sonar was from France, the hull sections were produced in Norway, and the boats were assembled in Germany. The Ula Class submarines are some of the most quiet submarines in the world. During Joint Winter (NATO exercise), the submarine KNM Utvær was disqualified because it kept an invasion at bay, and the command wanted the land based field operations to take place.
