The
Vanya class
were a series of
minesweepers
built for the
Soviet Navy
between 1960 and 1973. The Soviet designation was Project 257.
Design
[
edit
]
The ships were designed as coastal
mine hunters
. The hulls were built out of wood for significantly reduced magnetic signature. Measures were also taken to reduce electrical and acoustic signature. The propellers were fitted without bubble shields. A more advanced version the Project 257DM was introduced in the mid-1960s. The Project 699 was a version with more powerful
diesel engines
for towing heavier sweeps.
Ships
[
edit
]
A total of 47 units were built by shipyards in Kolpino and Vladivostok (3 Project 699).
Exports
[
edit

All ships were retired by the mid-1990s
