二次世界大戰資料庫 (WW2DB)

ww2dbaseThe SOC observation biplanes were built by Alexander Solla of the Curtiss-Wright Corporation. The first batch of aircraft were delivered to the United States Navy in late 1935, and by the end of the production run in 1938, 258 aircraft were built. Beginning in 1940, the Naval Aircraft Factory license-built 44 aircraft under the designation of SON. In 1941, the nickname Seagull was assigned. Although by the time WW2 began they were terribly out-dated, they continued to serve aboard battleships as gunfire observers and aboard cruisers as scouting aircraft. They were typically launched by catapults and recovered after landing in the relatively smooth-water "slick" that the turning mother ships could create on the open sea. When being stowed aboard ships, their wings folded back to conserve space. A few of them remained in US Navy service after WW2.
