The Yakovlev Yak-6 (NATO reporting name: Crib)[1] was a Soviet twin-engined utility aircraft, developed and built during World War II.

In order to minimise the use of scarce resources, the aircraft's fuel tanks were made of chemical-impregnated plywood rather than metal or rubber.

It could accommodate two crew side-by-side in an enclosed cockpit with capacity to carry four passengers or 500 kg (1,100 lb) or cargo.

[5][6] The second version was a light night bomber (designated NBB - nochnoy blizhniy bombardirovshchik - Short Range Night Bomber), capable of carrying up to 500 kg of bombs on racks under the wing centre sections and with a defensive armament of a single ShKAS machine gun in a dorsal mounting.

[13] After the end of the Second World War, some Yak-6s were supplied to allies, while it remained in large scale service with Soviet forces until 1950.
