Aircraft and History
The O-2A Skymaster, known as “Oscar Deuce” is a small twin engine aircraft used primarily as a Forward air controller (FAC) and psychological operations (PSYOPS). The USAF starting using the O-2 in 1967 in the Vietnam War as a replacement for the O-1 Bird Dog. With just a few years service, the O-2 was intended to be replaced by the OV-10 Bronco but the O-2 remained in service, primarily for night operations.
The USAF requested Cessna to make a military version of its 337 Super Skymaster with “hardpoints” under the wings, additional windows for observers and new cabin arrangement. A unique feature of the Skymaster is the engine arrangement. Unlike traditional twin-engine aircraft with engines on each wing, the Skymaster has one in the nose and another on the rear fuselage. This arrangement allows centerline thrust so if one engine loses power, aircraft control (in yaw) is minimal if any at all which is a significant safety advantage.
