Akademik Krylov Projects 852 and 856bis
Units of the Akademik Krylov class (projects 852 and 856bis Russian classification) were oceanographic research vessels that are no longer operational. These are not to be confused with the Akademik Krylov general cargo ships built 1940 and before (Summer DWT: 8,000 tons).
The Russian classification is Ekspeditsionnoye Okeanograficheskoye Sudno ( Expeditionary oceanographic vessel). The Akademik Krylov are characterized by large size and a displacement rather high. They were buit in two versions (Project 852 and Project 856), though these differences between the two are not known. These were well-equipped ships to carry out research, and are also equipped with a helipad for helicopters.
The Akademik Krylov units were built in Szczecin Poland, and entered into service between 1974 and 1979. They have been phased out since the early 1990s, due to high operating costs. The last time one of these ships was seen taking the sea dates back to 1997.
Altogether six were built. The class lead unit Akademik Krylov was sold in 1993, while Leonid Sobelyev was scrapped in 1996. The remaining four units (Admiral Vladimirskiy, Ivan Kruzenshtern, Leonid and Mikhail Demin Krupskiy) seem to have been held in reserve, but it is not impossible that some of these have been scrapped.
