McDonnell F-4B Phantom II, part four

The F-4B Phantom II also served with the United States Marines Corps, when the VMFA-314 "Black Knights" squadron received the F-4B in June 1962 at Marine Corps Air Station El Toro, in California. The first ones to be deployed in a conflict were the ones of the VMFA-531 "Gray Ghosts" when, on 10th May 1965 they were assigned to Da Nang air base, in the Republic of Vietnam, in order to provide air defence for the USMC.
The main role of the F-4B there was to provide close-air-support missions and soon later, more squadrons, VMFA-314, VMFA-232, VMFA-323 and VMFA-542 arrived at the Da Nang airfield.
Three MiGs were claimed by the USMC's F-4Bs, two of them while in an exchange duty with the Unites States Air Force, at the cost of 75 airplanes lost, most of them to anti-air fire and ground accidents.
