The USAF introduced the F-4C Phantom II into the Vietnam war in April 1965 from Ubon RTAB, Thailand. The F-4C/D soon became the Air Force’s principal fighter over the North, destroying 85 MiGs by the close of 1968. This book describes how the USAF turned a gunless naval interceptor into an opponent to the more nimble VPAF MiGs. It explains how the Air Force gradually followed US Navy initiatives in the use of the F-4’s missile armament but employed very different tactics and aircrew training. The roles of key personalities such as Col. Robin Oldany are discussed, together with armament and markings, crews and engagements.
