For ordinary operations in areas of the seas with shallow depths, diving vessels and boats of various displacement were used in the Navy of the USSR. Project 376 cutters were a large series of cutters that were built for the Soviet navy as well as civilian users starting in 1955 and are in use up to this day on the rivers and harbors for Russia. Diving boats of this project served on all fleets of the USSR and later - the Russian Federation. In total, more than 600 boats of this type were built.

Diving boat RVK-438 commissioned on 1975 and was assigned to the Black Sea Fleet Fleet.

Now in service.
