The North American Rockwell OV-10 Bronco is a light attack and observation aircraft developed in the 1960s as a counter-insurgency (COIN) and forward air control (FAC) aircraft. The original concept was for a rugged, simple, close air support aircraft integrated with forward ground operations.

A "tri-service" specification for the Light Armed Reconnaissance Aircraft (LARA) was approved by the U.S. Navy, Air Force and Army and was issued in late 1963. The specification called for a twin-engine, two-man aircraft that could carry at least 2,400 pounds of cargo. Various armaments to be carried included four 7.62 mm machine guns with 2,000 rounds, external weapons including a 20 mm gun pod and various sized rockets.

In August 1964 the North American Model 300 was selected and a contract for seven prototype aircraft was issued in October. The YOV-10A Bronco's maiden flight on 16 July 1965 and the OV10 became one of the premier counter-insurgency aircraft for the next 30 years.

North American Rockwell YOV-10A Broncos Bureau Numbers 152879 - 152885

152879 (NOV-10A - MSN 300-1) First listed at the North American Factory in Columbus, Ohio on January 27, 1967. Navy Aircraft History Cards (NAHC) from 1968, 1971 and 1972 show it first at NPRC R&T in Columbus until it went aboard the USNS Independence (CVA-62) on March 11, 1968. It then went to DCASC in Phoenix, Arizona. 152879 is listed as being at NATC Flight Test in Patuxent River, Maryland in 1969 and at NPRC Flight Test in Columbus, Ohio until April 24, 1971. SOC due to damage Jun 7, 1973.

152880 (MSN 300-2) First listed at the North American Factory in Columbus, Ohio on January 27, 1967. It is next listed at NPRL RDT&E in Columbus in 1971. To MASDC as 1V0015 on October 10, 1977. Returned to service. Reported at Mid-America Air Museum, Liberal, KS, on loan from Marine Corps Air-Ground Museum, Quantico, VA in the Spring of 2004. Photo: 152880

152881 (MSN 300-3) First listed at the North American Factory in Columbus, Ohio on January 27, 1967. Transfered to All Service Test & Evaluation at NAS Patuxent River, Maryland on August 28, 1967. Assigned to NASA on March 29, 1968. Next listed at NASA's Ames Research Center, NAS Moffett Field, CA Apr 8, 1968 to Oct 7, 1976. Registered as 718. Used for boundary layer control, STOL and V/STOL research. Served as the test bed for the rotating-cylinder-flap concept. The wing of the aircraft was modified to incorporate a two-segment flap located aft of the hydraulically driven rotating cylinder. The rotating cylinder in this case energized the boundary layer, thus keeping the airflow from separating from the wing flaps. At the same time, the cylinder also deflected the propeller thrust to provide a powered-lift component to the wing lift. Registered as N718NA Jun 25, 1969, cancelled May 26, 1976. Was with Yankee Air Force, Ypsilanti, Michigan. Destroyed in fire at Yankee Air Museum Sep 9, 2004.

YOV-10D - NSA Binh Thuy Vietnam - 1971

155395 was the first of two OV-10As converted to YOV-10Ds. The Marines wanted to make more of the Bronco by adding new sensors and heavier armament. North American Rockwell modified Bureau Numbers 155395 and 155396 to "YOV-10D" configuration in 1970. The gun sponsons were removed and a three-barrel General Electric M197 20 millimeter Gatling cannon in a turret was added under the rear fuselage. The Bronco's cargo space was used to accommodate the turret system and cannon ammunition. The nose was extended 30 inches to accommodate a turret-mounted "forward looking infrared (FLIR)" video imager. (Photo - YOV-10D 155395) After stateside tests at the Naval Air Weapons Staion China Lake, California the YOV-10D NOGS Broncos were shipped to Vietnam on April 26, 1971.

The two YOV-10Ds arrived in Vietnam on May 7, 1971 for combat evaluation with the VAL-4 "Black Ponies" at NSA Binh Thuy. Before & after the NOGS operated with the Black Ponies in 1971, average 20 mm ammunition usage was 5,138 rounds a month; from June 5 to August 13, 1971 the average usage went up to 50,527 rounds as the Black Ponies & NOGS fired 151,580 rounds. The YOV-10Ds flew 207 missions with 275 confirmed enemy kills and 23 injured, 63 sampans were destroyed and at least 30 damaged, 39 structures were damaged and 14 were destroyed, 19 secondary fires were noted and 36 secondary explosions were heard, 7 bunkers were destroyed and 19 damaged and 4 supply caches were destroyed/damaged. On January 31, 1972 155395 left VAL-4 at NSA Binh Thuy and returned to China Lake on February 1, 1972. 395 remained there until May 25, 1972.

155397 (MSN 305-8) First listed at the factory in Columbus, Ohio on March 15, 1968. To HML 267 at the USMC Base at Camp Pendleton, California on March 25, 1968. To the USMCR Base at Los Almitos, California from March 6, 1969 to September 7, 1970. Sent to VS-41 at NAS North Island in San Diego, California as a replacement for 155460 from September 9, 1970 to January 18, 1972. Then to VMO-2 at Camp Pendleton until June 28, 1972. 155397 crashed on April 30, 1981 and was written off as Damaged Beyond Repair. The pilot survived and was the only occupant of the aircraft that had taken off from Marrakesh Menara Airport, Morocco.
Morocco acquired six ex-USMC OV-10A-model airframes that were delivered in 1981 after being refurbished by Rockwell in Columbus. It was originally intended that Morocco would get 24 aircraft but political problems lead to the delivery of only 6. In January 1981 fifteen Marines made up of personnel from VMO-1 and VMO-2 formed a mobile training team called MTT-1-81 to train the Moroccan Air Force how to maintain and fly the OV-10 aircraft.
This was the first time Marines had ever been used for this purpose. They spent six month in Morocco at the Kenitra Air Base providing training. The first two aircraft flew over in February of 1981. Their route took them from Columbus, Ohio up the east coast of the U.S. and Canada over to Greenland, Iceland and then down the west coast of Europe and into Morocco. Two more followed in March and April.
The aircraft were to be used in the civil war being waged in the south by the Polisariso insurgents. During the operation of the aircraft one crashed and was destroyed, and another made a wheels up landing but was scrapped as repair was not within their capability. With the end of the war the aircraft were used for border and coast patrol, flying out of the Kenitra Air Base. In June of 1991 the OV-10A made their last flight to Meknes air base where they were put into storage.
The aircraft were last seen in April 2001. They were considered to be in very good shape, although there were minor things needing repair (stemming from the fact that they had been sitting for an extended period of time.)

155490 (MSN 305-101) Received new from the factory, 155490 was accepted by VAL-4 at NAS North Island on January 12, 1969. This airframe was only seven months old when it became VAL-4's first combat loss on July 19, 1969. 155490 was struck by enemy fire and crashed near the Three Sisters Mountains; 45 miles west of Saigon near Ap Bac, Chau Doc Province, South Vietnam. Per operational diary for US Navy Squadron VAL-4: "Bu No 155490 was shot down by enemy ground fire Saturday night, July 12 [1969]. Both pilots are classified as missing in action but there is little reason for hope. The airplane was observed to be receiving fire at 2,700 feet altitude, entered a shallow dive, and struck the top of a mountain 1,700 feet high. Explosion and fire ensued. No ejection seat rocket flame or inflated parachutes were in evidence. Air cover remained over the area all night and the next day, monitoring emergency radio frequencies, but received no signals. A survey of the crash site from the air the next day revealed that the aircraft had broken up upon initial contact with the top of the mountain and spewed parts over a wide area for several hundred yards down the mountainside. Since the mountains and valley below are occupied by enemy forces and there is no suitable terrain to land a helicopter in the area, there is no intention at this time for further investigation at the crash site. Since there was no radio transmission from the aircraft and that it appeared to be out of control after being hit by the ground fire, it is concluded that both pilots probably received fatal or incapacitating injuries prior to the crash". Both crew - Lt. Aubrey Grady Martin (pilot) and Lt.(jg) Roy Dean Sikkink (observer) - posted as MIA/KIA. The body of Lt. Martin was later found, and repatriated to the US on 31 July 1974, but not formally identified until 14 June 1977. The remains of Lt.
