How many air-to-air kills did the USAF's F-104 achieve in Vietnam?
Short answer
None: the USAF's F-104 recorded no air-to-air kills in Vietnam and was barely involved in aerial combat. Even so, it deterred MiG interceptors and performed well in close support. Between April and December 1965 it flew 2,937 combat sorties, and the war total reached 5,206.

The F-104C in Southeast Asia
The Starfighter saw action in the Vietnam War in 1965, seven years after the F-104C entered service in 1958 with the USAF's Tactical Air Command as a multirole fighter and fighter-bomber. On April 19, 1965, the 476th Tactical Fighter Squadron of the 479th TFW arrived at Da Nang Air Base to help protect American F-105 Thunderchief fighter-bombers against MiG-17s and, above all, against the MiG-21s that the Vietnamese air force was starting to operate. The F-104 was also used extensively as a barrier combat air patrol (BARCAP) escort for the EC-121D Warning Star early-warning aircraft patrolling off the North Vietnamese coast.
No air-to-air kills
The F-104s were barely involved in aerial combat and recorded no air-to-air kills during the conflict. The North Vietnamese were well aware of the F-104's performance, and pilots of the 479th TFW had the impression that the MiGs deliberately avoided engaging them. The F-104s deterred MiG interceptors and performed well as close support aircraft.
Sorties flown and losses
From the first F-104 deployment in April 1965 through December, the Starfighters flew 2,937 combat sorties. Five aircraft were lost: one from the 476th TFS, deployed from April to July 1965, and four from the 436th Tactical Fighter Squadron, deployed from July to October 1965. Afterward, the F-104s flew another 2,269 combat sorties, bringing the war total to 5,206.
