The Vanya class were a series of minesweepers built for the Soviet Navy between 1960 and 1973.

The hulls were built out of wood for significantly reduced magnetic signature.

Measures were also taken to reduce electrical and acoustic signature.

The Project 699 was a version with more powerful diesel engines for towing heavier sweeps.

[1] A total of 47 units were built by shipyards in Kolpino and Vladivostok (3 Project 699).
