Escort Carrier

Ex Mormacgulf Ingalls
Ex USS Breton ACV-10
Became Aagtekerk 1948,  E-Yung 1967


Chaser was built in the USA at Pascagoula, Mississippi, where she was laid down as mercantile Mormacgulf Ingalls on 28 June 1941, and launched 19 June 1942. She was purchased by the USN on 9 April 1943 as USS Breton ACV-10, and transferred to the Royal Navy.

HMS Chaser, as part of the "Attacker" Class was one of 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. Once the ships were ready for action they soon proved themselves, both as convoy escorts and fighter support ships for amphibious landings.

Chaser's war service included Convoy escort, mainly on Arctic routes. Aircraft from one of her squadrons, 816 squadron, assisted in the sinking of the German submarine U472 on 4 March 1944, and aircraft sank U366 and U973 in the following two days.

Chaser was returned to the USN on 12 May 1946, after which she became mercantile Aagtekerk 1948, and E-Yung 1967. She was scrapped at Kaohsiung in 1972.
