Cessna O-2A Skymaster. This military version of the Cessna 337 Super Skymaster saw active service in Vietnam and other theatres of war in the Forward Air Control role. Versatile, and much loved by its crews, there was also an O-2B 'psyops' version, equipped with powerful loudspeakers and a leaflet dispenser. This O-2A is seen at the Plymouth Airshow in Massachusetts, USA, and is shown with a typical load of white phosporus rockets, used to mark enemy targets. As well as US Armed Forces, they served no less than 14 other nations. #USAF #Cessna #CessnaO2A #CessnaO2B #vietnam #Massachusetts #FAC #PlymouthAirShow #USA #photography #aircraft #forwardaircontrol #aviationphotography #aviationlovers #avgeek #vietnamwar #aviation #kpym #plymouthmunicipalairport #airshow
