[2] The Falcons were re-designated Marine Fighter Attack Squadron 334 (VMFA-334) on 1 August 1967 and again transitioned airframes to the F-4J Phantom II.

The squadron arrived at Da Nang Air Base on 1 September and combat operations began almost immediately.

VMFA-334 remained in Vietnam until September 1969 when they were relocated to Marine Corps Air Station Iwakuni, Japan.

From there they flew air support over the US Navy intelligence ship the USS Pueblo, which had been attacked and captured by North Korea.

In March 1971 VMFA-334 returned to MCAS El Toro and was decommissioned later that year on 30 December 1971.
