The Grom-class Destroyers: ORP Błyskawica (H34) and ORP Grom – Fast and Heavily Armed Icons of WWII

The Grom-class destroyers, consisting of ORP Błyskawica and ORP Grom, were among the most powerful and fastest destroyers of their time, playing key roles during World War II. Designed for the Polish Navy, these ships were notable for their impressive speed, capable of reaching 39 knots (72 km/h; 45 mph), and their heavy armament, making them formidable opponents on the high seas.

ORP Grom and ORP Błyskawica were launched in the late 1930s, just before the outbreak of the war. These ships were designed with a dual purpose: to defend Polish shores and provide support to allied naval forces. They were equipped with advanced weaponry for the time, including multiple torpedo tubes, dual-purpose guns, and anti-aircraft capabilities.

Tragically, ORP Grom met its fate on May 4, 1940, during the Norwegian campaign in World War II. The ship was sunk in Ofotfjord, near Narvik, by German aircraft. Despite its loss, ORP Grom had already made a significant impact during the campaign, providing essential support to allied forces.

ORP Błyskawica, on the other hand, survived the war and is now preserved as a museum ship in Gdynia, Poland. Błyskawica continued to serve with distinction throughout the conflict, participating in key operations, including convoy escorts and engagements against enemy forces. Today, visitors to Gdynia can explore the ship and learn about its storied history, as it remains a proud symbol of Poland’s naval heritage.

The Grom-class destroyers are remembered for their speed, strength, and the crucial roles they played during World War II. ORP Błyskawica, in particular, stands as a living reminder of the bravery and resilience of the Polish Navy during one of the most challenging periods in history.
