The Rockwell OV-10 Bronco in Luftwaffe markings at the Kraków Air Show 2010.
OV-10 was used during the 1960s through the 1990s as an airborne observation and attack platform, being one of the finest counter-insurgency aircraft ever built.
Powered by two turbo prop engines, with its short high lift wing, maneuverable, rugged and with excellent handling characteristics, in U.S. Air Force, Navy and Marine Corps service the Bronco fought in Vietnam and the 1991 Persian Gulf War before the last was retired in 1995. Several foreign countries still operate the aircraft in guerrilla wars, including the Philippines (Luftwaffe Broncos were retired in 1990).
Boeing has recently put together plans internally to build a modernized, improved version of the OV-10 Bronco, called the OV-10X to satisfy a possible Air Force requirement for a light attack plane. While the aircraft would maintain much of its 1960s-vintage rugged external design, the 21st century modernizations would include a computerized glass cockpit, intelligence sensors and smart-bomb-dropping capabilities.
