Edited by Gordon Smith, Naval-History.Net

HMS Battler (Navy Photos, click to enlarge) return to Contents List 

ATTACKER-Class  Escort Aircraft Carrier obtained inter US/UK Land Lease Agreement.  The ship was under construction at Pascagoula, Mississippi by Ingalls and had bean laid down on 15th May 1941 for mercantile use as ss MORMACTERN.  She was requisitioned by the US Navy on 26th Dec. 1941 for conversion as an auxiliary (AVG) to be named USS ALTAMAHA and was launched on 4th April 1942 


This ship was transferred to the RN on 31st October 1942 when build was completed and and commissioned for service as HMS BATTLER, a name not previously used for an RN ship. Design changes made, based on the experience gained during build of the earlier ARCHER Class, included a larger hangar. Her propulsion machinery consisted of two steam turbines driving a single shaft as compared with Diesel engines used for previous conversions.
