Flying Tigers was the popular name of the 1st American Volunteer Group (AVG) of the Chinese Air Force in 1941-1942. Arguably, the group was a private military contractor, and for that reason the volunteers have sometimes been called mercenaries. The members of the Flying Tigers had lucrative contracts with the Chinese government with salaries ranging from $600 for a pilot to $750 for a squadron commander. These salaries were three times what they had been making in the U.S. forces. They were mostly former United States Army (USAAF), Navy (USN), and Marine Corps (USMC) pilots and ground crew, recruited under Presidential sanction and commanded by Claire Lee Chennault. The group consisted of three fighter squadrons with about 20 aircraft each. It trained in Burma before the American entry into World War II with the mission of defending China against Japanese forces.
The Tigers shark-faced fighters remain among the most recognizable of any individual combat aircraft of World War II, and they demonstrated innovative tactical victories when the news in the U.S. was filled with little more than stories of defeat at the hands of the Japanese forces.
The group first saw combat on 20 December 1941, 12 days after Pearl Harbor (local time). It achieved notable success during the lowest period of the war for U.S. and Allied Forces, giving hope to Americans that they would eventually succeed against the Japanese. While cross-referencing records after the war revealed their actual kill numbers were substantially less, the Tigers were paid combat bonuses for destroying nearly 300 enemy aircraft, while losing only 14 pilots on combat missions. In July 1942, the AVG was replaced by the U.S. Army 23rd Fighter Group, which was later absorbed into the U.S. 14th Air Force with General Chennault as commander. The 23rd FG went on to achieve similar combat success, while retaining the nose art and nickname of the volunteer unit.
