After being designated a Naval Aviator and commissioned as a
Second Lieutenant, Foss served cats instructor at
Pensacola, Florida and later attended the Navy School of Photography, at which time he was assigned to
Marine Photographic Squadron 1 (VMO-1) which was stationed at
NAS North Island in
San Diego, California. Eager for combat, he qualified in Grumman
F4F Wildcats while still assigned to VMO-1 and was eventually transferred to Marine Fighting Squadron 121
VMF-121 as the excutive officer. In October 1942, VMF-121 was deployed to the
South Pacific and became part of the
Cactus Air Force in the
Battle of Guadalcanal with Foss serving as the executive officer. On combat missions he led a flight eight Wildcats that became known as
Foss's Flying Circus. He shot down a
Japanese Zero in his first combat on
October 13, but his own plane was hit and with a dead engine and three more Zeros on his tail, he landed at full speed, no flaps and minimal control on the American runway at Guadalcanal, barely missing a grove of
palm trees http://www.medalofhonor.com/JoeFoss.htm.
By the time Foss left Guadalcanal in January
1943, his Flying Circus had shot down 72
Japanese aircraft, including 26 credited to him. As America's "ace of aces" he received the
Medal of Honor during a
White House ceremony in
1943, and appeared on the cover of
Life magazine.
Even though all of Foss' 26 victories were gained as a Marine Corps officer, the service continues recognizing
Gregory Boyington as its leading
ace. This is due to Boyington's wartime claims of 6 victories scored while serving with the
American Volunteer Group (Flying Tigers) prior to rejoining the Marine Corps, though the documented records prove otherwise (AVG records only show 2). (See Dr. Frank Olynyk,
Stars and Bars: A Tribute to the American Fighter Ace, 1995). Currently, the Marines
credit Boyington with 28 victories: six with the AVG in
China and 22 with the Marine Corps, the last two being unwitnessed. Boyington's total score recognized by the American Fighter Aces Association is 24: 2 with the AVG and 22 claimed with the Marine Corps. Boyington thus ranks behind Foss (26) and Robert M. Hanson (25).
A postwar attempt to film a story of Foss's life, starring
John Wayne, fell through when Foss refused to allow the producers to add a fictitious love story.
