ATTACKER-Class Escort Aircraft Carrier obtained under US/UK Land Lease Agreement. The ship was under construction at San Francisco by Western Pipe and Steel Corporation and had been laid down on 6th October 1941 .She was requisitioned by the US Navy for conversion as an auxiliary aircraft carrier on 26th December 1941 and was launched on 5th March 1942 as USS HAMLIN.


Transferred to the RN with 9 others of this Class after their the design changes authorised by the U S Navy were based on experience gained during build of the earlier ARCHER Class which included a larger hangar. The propulsion machinery was two steam turbines driving a single shaft instead of Diesel engines used for previous ships. She was formally transferred to the Royal Navy and commissioned as HMS STALKER on 21st December 1942 before the build completion on 30th October 1942. The name had been used previously by at Trawler hired in 1915.
