Long Island Class.
Long Island Class Escort Carriers
The Long Island-class escort carrier was a two-ship class, originally listed as "AVG" (Aircraft Escort Vessels). They were converted from merchant ships.
The first ship of the class - USS Long Island, originally AVG-1, later ACV-1 then CVE-1 - was launched on 11 January 1940, and served in the United States Navy through World War II.
The second and last ship of the class - HMS Archer (D78) - was launched on 14 December 1939, and served in the Royal Navy through World War II. It is also listed in U.S. Navy records as BAVG-1; the "B" presumably stood for "British".
