ww2dbaseThe Vigilant aircraft was designed in response to the 1938 United States Air Corps request for a new two-seat light observation aircraft design. The prototype aircraft, which took flight on 15 Jul 1940, was designated YO-49 during the evaluation period and O-49 upon acceptance. During the war, Vigilant aircraft operated as an artillery observation aircraft, towed gliders, and transported passengers and supplies. In Apr 1942, the US Army gave the O-49 Vigilant aircraft a new designation, L-1 Vigilant. They were made obsolete in 1942 upon the arrival of newer designs.

ww2dbaseDuring the design's production life, 324 examples were built.
