 Two submersibles of this design were built at Leningrad. They operated together with support vessels "Divnyy" and "Gordyy", which were converted from 393 type whale catchers.
 In 90s submersibles and support vessels became unnecessary. "Divnyy" sank at Novorossiysk in 1993. In 2000 refloated and scrapped. "PLB-76-01" sank at Novorossiysk too. "PLB-76-02" sank at Sevastopol. Four years later she was refloated and are waiting for further fate.
Purpose of the vessel:     - underwater teleshooting, filming and photography
    - hydrometric observations
    - sampling of water, soil and benthos when submerged
    - search and recording of fishery objects, and prediction and estimation of their stock
