Before Pearl Harbor, before the United States was officially at war, a hundred American pilots resigned their military commissions, boarded ships to Asia, and went to fight the Japanese in the skies over China and Burma. They were mercenaries in everything but name. They flew cast-off fighters with shark teeth painted on the nose. And in less than seven months of combat, they built a legend that hasn’t faded in 85 years.

The Flying Tigers — officially the 1st American Volunteer Group — were the brainchild of Claire Lee Chennault, a retired US Army Air Corps officer who had been advising Chiang Kai-shek’s Chinese air force since 1937. Chennault knew something Washington didn’t want to admit: Japan’s air power was devastating China, and the Chinese had almost nothing left to fight back with. He needed pilots. He needed aircraft. And he needed them before the diplomats were ready.

With secret approval from President Roosevelt, Chennault recruited pilots from the US Army, Navy, and Marine Corps. They were offered salaries of $600 a month — plus a $500 bonus for every confirmed kill. In 1941, that was extraordinary money. The volunteers signed contracts with a front company called the Central Aircraft Manufacturing Corporation, resigned their commissions, and sailed to Burma as civilians.

Outgunned, Outclassed, Outfighting

Their aircraft was the Curtiss P-40 Warhawk — a solid, dependable, and deeply average fighter. It was slower than the Japanese Ki-27 and Ki-43 fighters it would face. It climbed worse. It turned worse. In a classic dogfight, a P-40 pilot against a Japanese fighter was a dead man.

Chennault’s genius was refusing to fight classic dogfights. He developed tactics that exploited the P-40’s two advantages: it was heavier, which meant it dove faster, and it was tougher, which meant it could absorb punishment that would shred a lighter Japanese aircraft. His pilots would climb above the enemy, dive through the formation at high speed, fire a burst, and keep going. No turning. No chasing. Hit and run, again and again.

The results were devastating. In their first engagement on December 20, 1941 — just thirteen days after Pearl Harbor — the Flying Tigers intercepted a formation of Japanese bombers heading for Kunming and shot down at least three with no losses. Over the next seven months, the AVG racked up 297 confirmed aerial victories while losing just 14 pilots in air combat. The kill ratio was staggering for any unit, let alone one flying an inferior aircraft.

The Shark Mouth

The nose art wasn’t original — the shark-mouth motif had been used by RAF No. 112 Squadron on their P-40s in North Africa, and a Flying Tigers pilot spotted the design in a magazine. But it was the Tigers who made it immortal. Painted on the cowling of their P-40s, with eyes above and teeth below the air intake, the shark mouth became the most recognisable insignia of the Second World War. It’s been copied on aircraft, cars, surfboards, and tattoos ever since.

The AVG was disbanded on July 4, 1942, absorbed into the regular US Army Air Forces as America’s war machine fully mobilised. Some pilots stayed on. Others went home. Chennault was recommissioned as a general and continued to fight in China for the rest of the war.

They fought for money, for adventure, and — when the bombs fell on Pearl Harbor — for a country that hadn’t yet asked them to fight. The Flying Tigers existed for barely half a year. Their legend has outlived every aircraft they ever flew.
