The OV-10 Bronco, a rugged, maneuverable, twin-turboprop, multimission aircraft, was designed and built by North American at Columbus, Ohio. The Bronco complemented the performance requirements between jets and helicopters. Faster and more tactically versatile than helicopters, yet slower and more maneuverable than jets, the Bronco utilized tactics not possible with either. The OV-10D night observation system (NOS) featured a unique night observation and target marking system that included forward-looking infrared (FLIR) and laser designator/ranger. With uprated 1040 SHP turboprop engines and fiberglass propellers, NOS provided greater range, improved performance and greater survivability.
