HMS Hussar was a Royal Navy Halcyon-class minesweeper of World War II.

As the Allied armies advanced following the invasion of Normandy, Hussar, Britomart, Jason and Salamander were assigned to the 1st Minesweeping Flotilla (1MF) clearing Axis minefields north of Normandy to open additional ports to supply the advance.

On the afternoon of 27 August 1944, they were sweeping off Cap d'Antifer in preparation for the battleship Warspite and monitors Erebus and Roberts to engage Le Havre coastal artillery delaying the advance of Canadian troops.

The squadrons responded with 16 Typhoons armed with 20 mm cannon and High Explosive "60 lb" RP-3 unguided rockets.

[1] In a well-executed attack out of the sun at 13:30, the Typhoons sank Hussar and Britomart; and Salamander was damaged far beyond economical repair and written off as a constructive total loss.
