In 1948 the USAF, Marine Corps and US Navy were concentrating on
converting over to an all-jet force. When the Korean War started in June
1950, the USAF had built up a sizable jet force in the Far East, while
the US Navy was in the early stages of getting F9F Panthers operational
as replacements for its piston-engined F8F Bearcats. At about this time,
the Marine Corps had also begun using the Panthers in limited numbers.
Operating from aircraft carriers off the Korean coast, F9Fs helped stop
the North Korean invasion within two weeks of the communists crossing
the 38th Parallel. The Panthers, escorting carrier-based AD Skyraiders
and F4U Corsairs, penetrated as far north as Pyongyang, where they
bombed and strafed targets that the North Koreans thought were out of
range. The Panthers also took the battle all the way to the Yalu River,
long before the MiG-15s became a threat. The F9F's basic tasking was
aerial supremacy and combat air patrols, but they also excelled in
bombing and strafing attacks. The Marine Corps, with its two Panther
squadrons, was also involved in close air support and interdiction near
the frontlines. There were a total of 32 Panther squadron deployments
during the war, along with several special detachments that operated the
F9F-2/5P unarmed photo-reconnaissance versions.
