North Vietnamese SAM Downs U.S. F-4 Phantom
July 24, 1965
North Vietnamese troops fire multiple Soviet-built, radar-guided, surface-to-air missiles (SAMs) at a flight of U.S. Air Force F-4 Phantoms over North Vietnam. One SAM downs the Phantom flown by pilot Captain Richard P. Keirn and radar intercept officer Captain Roscoe H. Fobair. This is the first instance of a SAM successfully destroying a U.S. aircraft in Vietnam, a significant moment in the history of air combat. Fobair is killed. Keirn successfully ejects and is captured. He spends almost eight years as a POW.1
