The Cal-Fire OV-10 Bronco was originally a turboprop light attack and observation aircraft. Built by North American Rockwell in the 1960s as a special aircraft for military COunter INsurgency(COIN) combat, its primary mission was designated as a Forward Air Control (FAC) aircraft. The canopy design offers excellent visibility, a very important feature when it came to CDF/Cal-Fire upgrading from the old Cessna O-2 Skymasters.
