North American Rockwell OV-10A Mockup


The OV-10A is a twin-turboprop short takeoff and landing aircraft conceived by the U.S. Marine Corps and developed under a U.S. Air Force, Navy and Marine Corps tri-service program for a Light Armed Reconnaissance Aircraft (LARA). The North American Rockwell aircraft first flew on July 16, 1965. The first production OV-10A was ordered in 1966, and its initial flight took place in August 1967.
The Broncos US military missions included observation, forward air control, helicopter escort, armed reconnaissance, gunfire spotting, utility and limited ground attack. The USAF acquired the Bronco primarily as a forward air control (FAC) aircraft. Adding to its versatility is a rear fuselage compartment with a capacity of 3,200 pounds of cargo or five combat-equipped troops or two litter patients and a medical attendant.

On July 6, 1968, the Marines first OV-10s arrived at Marble Mountain, Vietnam, and flew its first mission that day. The first Air Force OV-10s also arrived shortly thereafter. The nearly 300 aircraft were all produced at Air Force Plant Number 85 at Port Columbus Airport in Ohio. The last one was built in 1976.

The Air Force retired their last OV-10 in 1991, but the Marines continued to operate theirs until July 1994. Foreign governments and other US Government agencies – Bureau of Land Management, Bureau of Alcohol, Tobacco, and Firearms, and the California Department of Forestry and Fire (CDF) – continued to operate OV-10s.

AIRCRAFT HISTORY

The Fort Worth Aviation Museum has three OV-10s – this USMC aircraft, a USAF aircraft, and the production mockup. This is the full-scale factory mockup of the OV-10A, c/n NAA-001, that was made in Columbus, Ohio. It was acquired by the museum in 2001. The aircraft is made from a mix of materials.
