Aircraft facilities


Aircraft fuel stowage was 1 020 500 l. There were 3 heavy cranes for handling seaplanes.

Project history


First USN modern purpose-built seaplane tenders. According to the design, each of them should maintain two seaplane squadrons and provide small repair of aircraft. For this purpose the deck aft has been exempted for placing of aircrafts requiring repair, and there was a hangar in a superstructure with necessary equipment. Seaplanes were lifted onboard by three powerful cranes (one on aft part of the aviation deck and two on a superstructure). Hull had underwater protection, aviation fuel tanks took places below a waterline. Total stowage of an aviation fuel notably exceeded accepted for aircraft carriers.

Ship protection


There was 4-compartment underwater protection.

Modernizations


1941, Curtiss: + CXAM-1 radar

1942 - 1943, both: - 10 x 1 - 12.7/90; + 2 x 4 - 40/56 Mk 1.2, 12 x 1 - 20/70 Mk 4, Mk 26 radar

1945, Curtiss: (presumably) - CXAM-1 radar

1944 - 1945, both: + 2 x 4 - 40/56 Mk 1.2, presumably SG, SK radars

1.1946, both: 4 x 1 - 127/38 Mk 30, 4 x 4 - 40/60 Mk 2, 12 x 1 - 20/70 Mk 10, 30 seaplanes, presumably SG, SK, Mk 26 radars
