Developed from Cessna Skymaster

The Cessna O-2 Skymaster (nicknamed "Oscar Deuce") is a military version of the

psychological operations
(PSYOPS) by the US military between 1967 and 2010.

Design and development

The O-2 lacks the 337 propeller spinner

In 1966, the United States Air Force (USAF) commissioned Cessna to build a military variant of the Skymaster to replace the Cessna O-1 Bird Dog.

Both the civilian and military Skymasters were low-cost twin-engine piston-powered aircraft, with one engine in the nose of the aircraft and a second in the rear of the fuselage. The push-pull configuration provided centerline thrust, allowing simpler operation than the low-wing mounting of most twin-engine light aircraft, and allowed a high wing to be used, providing clear observation below and behind the aircraft.

Modifications made for the military configuration included fore-and-aft seating for a pilot and observer, instead of the six seats of the civilian version; installation of view panels in the doors (for improved ground observation); installation of flame-retardant foam in the wing-mounted fuel tanks (slightly increasing weight, and reducing maximum fuel capacity by 3%); installation of military, rather than civilian, communication and navigation equipment and antennas; removal of

propeller spinners
; increased gross weight (5,400 lb vs. 4,400 lb in civilian version), with component strengthening as required to support the increase; and removal of interior upholstery.

The first O-2 flew in January 1967, and the plane went into production shortly thereafter. Performance (especially at cruising altitudes) was degraded due to the added antennas and significant weight increase, but was considered sufficient for the anticipated low-level operation.

Operational history

United States

U.S. Air Force

O-2B Skymaster dropping leaflets over Vietnam

The USAF took delivery of the O-2 Skymaster in March 1967 and the O-2A also entered the U.S. Army's inventory during 1967, from USAF stock. By 1970, a total of 532 O-2s had been built, in two variants, for the USAF.

During the

psychological operations
(PSYOPS) role.

While it was intended that the Skymaster be replaced in the FAC mission by the

OV-10 Bronco, the O-2A continued to be used for night missions after the OV-10's introduction, due to the OV-10's high level of cockpit illumination, rendering night reconnaissance impractical.[1] The O-2 was phased out completely after additional night upgrades to the OV-10.[2][3]

A total of 178 USAF O-2 Skymasters were lost in the Vietnam War, to all causes.[4]

Following the Vietnam War, the O-2 continued to operate with both

U.S. Air Force and Air National Guard
units into the late 1980s.

U.S. Navy

Six former USAF O-2A airframes were transferred to the

T-34C Turbomentor
aircraft transferred from the Naval Air Training Command.

U.S. Army

Of the six USN aircraft mentioned above, two were transferred to the

Davis-Monthan AFB, Arizona.[5] Two O-2As were used at Laguna Army Airfield, Arizona as part of testing programs carried out by the Yuma Proving Ground. These were retired in October 2010 and sent to a museum.[6]

South Vietnam

35 USAF O-2 aircraft were later transferred to and operated by the former

Republic of Vietnam Air Force.[3]

El Salvador

During the

FMLN
formations and direct air strikes against them, playing a major role in forcing the rebel movement to abandon large-scale operations.

Near the end of the war in 1990, the rebels' acquisition of

SA-7 missiles resulted in the loss of two O-2As, while another was destroyed by mortar fire, and two more were lost in crashes.[7]

Civilian use

CAL FIRE

In the mid-1970s, the

Davis-Monthan Air Force Base. The best 20 were selected and shipped to Fresno, California. These aircraft had been FAC aircraft in Vietnam and were shipped back to the United States in containers, and were disassembled and on pallets when they arrived at Fresno. A crew of California Conservation Corps
(CCC) members under the supervision of a CDF Battalion Chief, who was an FAA Certificated Mechanic with Inspection Authorization (IA), reassembled the aircraft.

They were placed in service in 1976, and served CAL FIRE for more than 20 years, until replaced by a fleet of

OV-10 Broncos.[8]

Variants

Version designed for use in forward air control missions, with underwing ordnance hard points to hold rockets, gun pods or flares. 513 delivered.[3]
O-2B
Version designed for psychological warfare, equipped with loudspeakers and a leaflet dispenser, and not armed. Thirty-one former civil 337s were converted to O-2Bs.[9]
