BBC Project 1174 had many shortcomings, so as directed by the Commander of the Soviet Navy Admiral S. Gorshkov was started to develop a full-fledged amphibious assault ship, which was carried out development of all 80 years. Character and purpose of the ship changed during development. The original purpose of the ship were only landing operations. UDC had to have a continuous deck, allowing use as helicopters and aircraft vertical takeoff and landing Yakovlev Yak-38. General Staff proposed project to transform 11 780 ships in the universal aircraft-carrying ships, equipped them with a bow ramp and providing basing and other aircraft.
Assumed the construction of two ships - "Soviet amphibious assault ship Kherson" and "Soviet amphibious assault ship Kremenchug". Ships standard displacement of 25,000 tons can only be built on the Black Sea Shipyard, so began the "struggle for the stocks." At this time, the stocks CSY was scheduled to begin construction of aircraft carriers Project 1143,5. The General Staff, attaching great importance to the construction of UDC, offered to build them instead of aircraft carriers.
This is opposed Commander of the Navy. Realizing that the construction of UDC, because of the lack of required shipbuilding capacity is likely to lead to the abandonment of the construction of aircraft carriers project 1143.5, went to the trick. As directed by the Commander of the nose, right on the flight deck, was placed AK-130, Research Institute of the Navy job was "scientifically" prove the existence of such weapons and its location. As a result, the General Staff had become indifferent to the project, but construction was delayed.
At the request of the Minister of Defense Marshal Ustinov objectives of the project was added to 11 780 in peacetime tracking enemy submarines in the ocean zone. Ultimately, all these changes have led to the ships of the project and 11 780 were not included.
In the ASW variant of the ship would carry 25 Kamov Ka-27. In landing variant - 12 transport helicopters Kamov Ka-29. In the dock the camera - 4 landing craft Project 1176 and 2 amphibious hovercraft Project 1206.
The lead ship of the class, Kherson, was put into operation in the late 1980s.
