ORP Kaszub is a corvette of the Polish Navy, in service since 1987,[3] the sole ship of the Project 620 class.

[4] The work on her design began in 1971,[citation needed] but the construction of the first ship started only in 1984, being laid down at Stocznia Północna (Northern Shipyard), Gdańsk on 9 June 1984.

Kaszub was launched on 11 May 1986,[1] but was found to have a warped hull and propeller shafts, which required repair.

[5] At first, Kaszub saw little operational use, being loaned to the Polish Border guard from 1990 to January 1991.
