Aircraft facilities

 (fd - 7,349 m², ha - 2,920 m² / 18,687 m³): Flight deck: 268.2 x 27.4 m. Hangar: 129.2 x 22.6 x 6.4 m. Elevators: fore (9.0 x 18.1m, 7.3t) and aft (8.9 x 10.6m, 2.7t). One 47m catapult F Mk 1. Aircraft fuel stowage in 1942: 520 500 l.

Project history

Largest and fastest aircraft carriers of their time. They were laid down as battlecruisers, but after Washington conference re-ordered as aircraft carriers (CV2 and 3 22.11.1922 and 30.10.1922 respectively). Concerning applied construction and architecture decisions Lexington and Saratoga appreciable effected on the further development of aircraft carriers. Their flight deck and outside hangar sides were designed as a part of hull construction, participating in providing of the longitudinal strength (unlike the subsequent ships, having the flight deck and a hangar fulfilled as a superstructure). Similar constructive decision has ensured a certain prize in hull weight and allowed to make a single-level hangar completely closed. Aft from hangar there were repair shops, there were holds for taken apart planes below it. Two elevators were arranged close enough to each other. Aft one was intended only for fighters, and fwd for heavy planes. Curious feature of fwd elevator was that it could lift aircrafts with the length of a fuselage bigger of elevator length with help of additional folding 6x8m hatch. At the same time presence of only two elevators on so huge ships became serious miscalculation of designers and later negatively affected efficiency of combat usage of carrier aircraft.

Lexington and Saratoga had unusual turbo-electric machinery with huge power: 180000hp. Turbo-generators were installed in central compartments, and boiler rooms at the left and to the right of them alongsides. According to 1920th tactical doctrines, aircraft carriers were armed by 8 203mm guns in four turrets.

Ship protection

Main 178mm belt had 161.5m length and 2.9m height. It was connected with flat 51mm main deck at upper edge. Underwater protection had 4.8m depth and included 4 compartments.

Naval service

Lexington 7.5.1942 during battle in Coral sea was badly damaged by Japanese carrier aircraft (from carriers Shokaku and Zuikaku, received two torpedo and two 60kg bomb hits), abandoned by crew and torpedoed by destroyer Phelps. She foundered 8.5.1942.

Saratoga 11.1.1942 was damaged by a torpedo from Japanese submarine I16 and was under repair till late May, 1942; 31.8.1942 she was again torpedoed by Japanese submarine I26 and returned to service in late November, 1942; during Iwo Jima landing 21.2.1945 she was badly damaged by Japanese aircraft (hits of four bombs and two kamikazes), returned to service in May, 1945; later she was used at nuclear tests at Bikini, damaged 1.7.1946 and sunk after explosion 25.7.1946.
