The Ugra class was the NATO reporting name for a group of seven submarine tenders built for the Soviet Navy in the late 1960s. The Soviet designation was Project 1886. One further ship was built for the Indian Navy to a modified design. The ships were intended to provide afloat support for Soviet submarines, including supplies, water, torpedoes, fuel, and battery charging; minimal repair facilities, and were often employed as flagships/command ships for submarine squadrons. A subclass, the Borodino class, of two ships were constructed for use as training ships and lacked missiles and the ability to support submarines. Instead, the Borodino class had classrooms and training facilities.
