HMS Strongbow was an S-class submarine of the Royal Navy, and part of the Third Group built of that class.

Strongbow was detected on the surface off Port Swettenham, Malaya on 13 January 1945.

Japanese escorts, minelayer Hatsutaka, sub chaser CH-9, auxiliary sub-chaser CHa-41 and one other, soon arrived to attack her.

Strongbow managed to escape but sustained such depth charge damage during a 14-hour attack that she was rendered unfit for further service.

She was decommissioned at Falmouth in June 1945, and scrapped at Preston in April 1946.
