USN:
USS Yorktown (CV-5) in Dry Dock No. 1 at the Pearl Harbor Naval Shipyard, receiving urgent repairs from damage received during the Battle of the Coral Sea, she left Pearl Harbor the next day to participate in the Battle of Midway. 29 May, 1942
October 21st 1944, USS New Mexico at Puget Sound Navy Yard.
USS Admiralty Islands (CVE-99) off the California coast, 30 August 1945
The
Casablanca class is unusual and interesting from a postwar standard.
During WWII, these and the
Bogue classes were considered the worst of the CVEs, and they were often assigned to transport and training duties (by July 1945, 22 combat, 10 training, and 25 transports). According to early 1944 aviation schedules
Admiralty Islands, and all of the last eight
Casablancas, was initially slated to be a combat carrier, but a month after completion she was assigned to the Carrier Transport Squadron, where she remained until the end of the war.
After the war, the US had 45 remaining
Casablanca class carriers, and kept 34 in reserve until the late 1950s for potential use as helicopter carriers and aircraft transports (most struck en masse 1958-1960). Of the 11 struck and scrapped in 1946-1947, the reasons behind why certain ships were retired isn't clear. For example, of the four Taffy 3 CVEs to survive,
Kalinin Bay (severely damaged and becoming a transport carrier after repairs) and
Kitkun Bay (combat carrier to end of war despite a January 1945 kamikaze) were struck in 1946, but
White Plains (which had major machinery damage form shellfire) and
Fanshaw Bay stayed in reserve.
But
Admiralty Islands history is clear. DANFS makes many constant references to machinery trouble, including one time when two of her four boilers were inoperative. While there were three different boiler manufacturers for the class, there is no obvious pattern of ships with Babcock and Wilcox boilers like
Admiralty Islands being retired early: four of the 16 were struck in 1946-1947, compared to five of 15 Foster Wheeler ships and two of 14 Combustion Engineering ships.
