The Grom class was a destroyer - class of the Polish Navy in World War II and after.

The two Polish warships were built in Great Britain between 1935 and 1937, evacuated to Great Britain as part of Operation Beijing before the start of the war, and took part in various Allied naval operations during World War II.

Construction and design features

To complement the outdated Wicher class destroyers , the Polish Navy ordered from the British shipyard John Samuel White & Co Ltd. two more modern heavy destroyers at Cowes on the Isle of Wight . Construction of both ships began in 1935. The ships' operational concept included coastal protection and escort protection .

With the three steam boilers , the two Parsons turbines on two shafts together 54,000  hp power levies, the destroyers were up to 39.5  knots go, which they, the speed of the destroyer Farragut - Porter - La Fantasque - or tribal - Class exceeded.

The ships were relatively large with a maximum displacement of 2,400  ts for the shallow and narrow waters of the Baltic Sea .

Due to the size of the ship and the range of 3,500  nautical miles , the destroyers were theoretically able to escort convoys of allied forces from Great Britain and France to both Gdynia and Constanța in Romania .

The Błyskawica was in use for almost 40 years and was rebuilt and modernized several times. The modifications took place in 1941, 1942 and 1951. The armament was mainly adapted to the new operational tasks and the standards of the respective allies.
