HMS STRIKER (D 12) - Attacker-class Escort Aircraft Carrier
including Convoy Escort Movements

HMS Fencer, sister-ship (Navy Photos/Mark Teadham, click to enlarge) return to Contents List 

ATTACKER-Class Escort Aircraft Carrier obtained under US/UK Lend Lease Agreement. The ship was under construction at San Francisco by Western Pipe and Steel Corporation a mercantile and laid down on 15th December 1941. After requisition by the US Navy for conversion to enable her to be used as an auxiliary aircraft carrier (CVE) named USS PRINCE WILLIAM she was launched on 7th July 1942. One of nine similar ships she was later selected for transferred to the RN.  Changes in the US design were made based on the experience gained with the earlier ARCHER Class and included a larger hangar. Propulsion machinery consisted of two steam turbines driving a single shaft instead of Diesel engines used for previous ships. Her build was completed on 28th April 1943 and she was formally transferred to the RN on 29th April when she commissioned as HMS STRIKER.  British radar outfits were fitted.. This name had not  previously used for a Royal Navy warship
