ORP Jaskółka was the lead ship of her class of minesweepers in the Polish Navy at the outset of World War II.

Jaskółka was built at Gdynia; launched 11 September 1934; and commissioned 27 August 1935.

[1] On 1 September 1939, Jaskółka under the command of captain Tadeusz Borysiewicz, along with other minesweepers, engaged in combat with German aircraft on their way to execute a bombing raid of the Hel Peninsula, in what became known as the Battle of the Gdańsk Bay.

On the night of 12 September, Jaskółka and Czajka fired upon German positions.

On 14 September, Jaskółka was sunk after it was hit by a German bomb in the port of Jastarnia.
