Escort Carrier

Ex Mormactern
Ex USS Altamaha AVG-6


HMS Battler was built in the USA at Ingalls, Pascagoula, Mississippi on 15 April 1941, being laid down as mercantile Mormactern, launched 4 April 1942, converted as USS Altamaha AVG-6, and transferred to the RN on completion 31 October 1942. She was commissioned as HMS Battler on 15 November 1942.

The "Attacker" Class were the second batch of escort carriers built in the USA for the Royal Navy, the lead ship - Attacker - having originally been intended to be one of the "Avenger" Class. They were also the first escort carriers to be ordered after the USA entered the war; the USN kept the other 10 vessels ordered at the same time, as these became the "Bogue" Class. Speed was increased to18 knots, although overall size and displacement were much the same as the earlier classes. Although the first of the class arrived in the UK in January 1943, none actually commenced active service until August of that year. Once the ships were ready for action they soon proved themselves, both as convoy escorts and fighter support ships for amphibious landings.

HMS Battler served in WWII providing convoy escort in the Atlantic and Indian Ocean. She returned to the USN on 12 February 1946. She was scrapped at Baltimore.
