In order to test the whole variety of new equipment and train cadets on it and retrain officers, an experimental and training ship of Project 13040 with a displacement of 6,000 tons was developed and prepared for construction. The most valuable thing is that it had almost the entire range of weapons. The development was carried out by the Northern Design Bureau in 1985-1986. The same Design Bureau simultaneously (1985-1986) developed a patrol and rescue vessel of Project 10590 ice class for work in the northern seas and the Far East. The need for such a vessel was acutely felt. Ships of this class were not built for a very long time, practically since 1952, with the exception of small "border guards" of Project 745.
