The Skyknight was the only Korean War jet fighter that also flew in Vietnam.
EF-10Bs served in the Electronic warfare role during the Vietnam War until 1969.
The large interior provided ample room for electronic equipment.
U.S. Marine Composite Reconnaissance Squadron One VMCJ-1 Golden Hawks began operating the EF-10B on 17 April 1965 under Lt.
Col Wes Corman at Da Nang Air Base Republic of Vietnam with six aircraft.
No more than 10 EF-10Bs were in Vietnam at one time.
The Electronic Warfare (EW) Skyknight was a valuable Electronic countermeasure (ECM) asset to jam the SA-2 surface-to-air missiles (SAM) tracking and guidance systems.
VMCJ-1 made history when its EF-10Bs conducted the first USMC airborne radar jamming mission on 29 April 1965 to support a USAF strike mission.
Four EF-10Bs also supported a massive strike on the SAM sites near Hanoi on 27 July 1965.

Many U.S. aircraft were lost to SA-2s in Vietnam and the electronic attack on the associated radar systems was known as "Fogbound" missions.
The F3D also dropped chaff over the radar sites.
The first EF-10B lost in Vietnam was to an SA-2 on 18 March 1966, while four more EF-10Bs were lost in Vietnam to accidents and unknown causes.
Their mission was gradually taken over by the more capable EA-6A "Electric Intruder", an Electronic Warfare/Electronic Countermeasures (EW/ECM) variant of the Grumman A-6 Intruder attack bomber.
The EF-10B Skyknight continued to fly lower–threat EW missions until they were withdrawn from South Vietnam in October 1969.
The U.S. Navy's EKA-3 Skywarrior and the USAF's Douglas RB-66 Destroyer also took on EW missions.

The U.S. Marine Corps retired its last EF-10Bs in May 1970.
