ORP Kaszub is a corvette of the Polish Navy, in service since 1987,[3] the sole ship of the Project 620 class. She was the first ocean-going warship built in Poland. As of 2012 she is in active service.[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.[2] When the ship commissioned on 15 March 1987,[1] Kaszub was not fitted with much of the planned armament, with a 9K33 Osa (NATO codename SA-N-4 Gecko) surface-to-air missile launcher being omitted because of its unreliability on small, high speed ships, while the ship's main gun armament was absent because of stability problems.[5] Originally it was planned to build 7 ships of this class, but in the end only one was constructed.[5]

At first, Kaszub saw little operational use, being loaned to the Polish Border guard from 1990 to January 1991. In September 1991, the ship was fitted with a AK-176 76 mm (3.0 in) gun turret forward[2]
