History
The first production P-40s began to appear in May 1940, and the US Army elected to defer delivery of the new fighter to allow production and delivery of the export version (known as the Hawk 81A) to France. However, the initial production version was hardly combat ready, lacking armor protection and self-sealing fuel tanks, and deliveries weren’t able to be made until September 1940. By then France had fallen and the RAF had taken over the production order from the French Air Force. The British replaced the two .30 caliber Browning machine guns in the wings with guns chambered for .303, but retained the two .50 caliber machine guns in the nose. With some armor protection and self-sealing fuel tanks, the new machine was designated the “Tomahawk IIA” for RAF service, and was virtually identical to the US AAF’s P-40B, which began to reach service units in early 1941.
For the next variant, the P-40C model (Tomahawk IIB to the RAF), improvements were made to the self-sealing fuel tanks and an additional .30 caliber machine gun was added to each wing, which increased gross weight and reduced the maximum speed. By the time the Japanese attacked Pearl Harbor, the Army had 62 P-40Bs and 11 P-40Cs in Hawaii, the majority of which were destroyed on the ground. However, several survived the initial attack and were able to score the AAF’s first “kills” of the war.
Two weeks later, on December 20, 1941, the American Volunteer Group, aka the “Flying Tigers”, took to the skies in their P-40Cs Warhawks and destroyed six of ten Japanese bombers attacking Chinese Kunming.
Strengths
- Durability — The P-40 can absorb considerable battle damage and still bring its pilot back home.
Weakness
- Guns — Four .30 caliber and two .50 caliber guns are insufficient to deal much damage to enemy planes, particularly bombers.
- High Altitude Performance — While it is nimble and agile at low altitudes, the lack of a decent supercharger makes the P-40 a sluggish performer above 10,000 feet.
