The Aeronca O-58, later redesignated the L-3 Grasshopper, was a light observation and liaison aircraft used by the U.S. Army during World War II. Based on the Aeronca Model 65 Defender, it was one of several civilian aircraft adapted for military use under the "Grasshopper" program, designed to support ground forces with reconnaissance, artillery spotting, and communication.
The L-3 was known for its short takeoff and landing (STOL) capabilities, enabling it to operate from improvised airstrips close to the front lines. It featured tandem seating, excellent forward and side visibility, and minimal instrumentation, making it simple to fly and maintain. While unarmed and vulnerable in combat zones, its strategic value came from its agility and reliability in challenging field conditions.
L-3s were instrumental in the early phases of WWII, particularly in training missions and stateside operations, before being supplanted by more advanced liaison aircraft like the Piper L-4 and Stinson L-5. Today, surviving L-3s are treasured for their historical significance and role in shaping modern forward air control strategies.
