The Aeronca L-3 group of observation and liaison aircraft were used by the United States Army Air Corps in World War II. The L-3 series were adapted from Aeronca's pre-war Tandem Trainer and Chief models.

Design and development[edit]

In 1941, the United States Army Air Corps ordered four examples of the Aeronca 65 TC Defender, designated YO-58, for evaluation of the suitability of light aircraft for observation and liaison purposes. (It also placed similar orders with Piper and Taylorcraft Aircraft). Service tests during the US Army's annual maneuvers proved successful, and resulted in large orders being placed. In 1942, the O-58 was redesignated L-3.[1][2]

When American forces went into combat after Pearl Harbor, the Army Air Force used the L-3 in much the same manner as observation balloons were used during World War I — spotting activities and directing artillery fire. It was also used for liaison and transport duties and short-range reconnaissance which required airplanes to land and take off in short distances from unprepared landing strips. Liaison pilots would train on L-3s before moving on to front-line aircraft like the Piper L-4 or the Stinson L-5. Some L-3s were shipped to north Africa, and subsequently given to the Free French Forces in the area at the time. At least one of the aircraft served with US forces in Italy.[citation needed]

The TG-5 was a three-seat training glider of 1942 based upon the O-58 design. This aircraft retained the O-58's rear fuselage, wings, and tail while adding a new front fuselage in place of the engine. In all, Aeronca built 250 TG-5 gliders for the Army. The Navy received three as the LNR-1.[3]
