Convoy PQ 15 was an Arctic convoy sent from Iceland by the Western Allies to aid the Soviet Union during World War II. It sailed in late April 1942, reaching the Soviet northern ports after air attacks that sank three ships. Twenty-two ships arrived safely.
The convoy consisted of 25 merchant ships and was accompanied by one auxiliary, the oiler RFA Gray Ranger, which travelled with her own escort of destroyers.
The Close Escort was led by Commander J. Crombie in the minesweeper HMS Bramble and consisted of two other minesweepers and four trawlers, joined later by four destroyers and the antiaircraft ship HMS Ulster Queen.
There were two support groups: a Cruiser Cover Force led by Rear Admiral H. M. Burrough in the light cruiser HMS Nigeria, with the heavy cruiser HMS London and two destroyers; and a Distant Covering Force led by Admiral John Tovey, comprising the battleships HMS King George V and USS Washington (BB-56), (Rear Admiral Robert C. Giffen, USN, commanding), the aircraft carrier HMS Victorious, the heavy cruisers USS Tuscaloosa (CA-37), and USS Wichita (CA-45), the light cruiser HMS Kenya, and 10 destroyers.
