In all, the P-40 proved itself a worthy and rugged fighter.
The Curtiss P-40 Warhawk was the third most widely produced American fighter of World War II, after the North American P-51 Mustang and the Republic P-47 Thunderbolt. First introduced in 1939, the P-40 was a staple of the Allied air forces throughout North Africa, the South Pacific, and China.
While the P-40 has gained a reputation as a lackluster air superiority fighter, best used only in a close air support role, the P-40’s actual combat record suggests adequate air superiority performance. Indeed, more than 200 Allied fighter pilots became aces in the P-40.
Introducing the P-40 Warhawk
Over 13,000 P-40s were built—all in Buffalo, New York, at the Curtiss-Wright Corporation’s main production facility. The P-40’s design was based on the Curtiss P-36 Hawk, which saved time and costs relative to building a new plane from scratch. Originally conceived as a pursuit aircraft, the P-40 was agile at low and medium altitudes, but did not have the power to perform impressively in the thinner air at higher altitudes. Similarly, it lacked climbing power; climbing to 15,000 feet took the pilot over six minutes. However, the aircraft did have an impressive dive speed. The maximum speed for the P-40 was just 361 miles per hour, with a range of 716 miles, and a service ceiling of 29,100 feet.
The P-40’s lack of power stemmed from the Allison V-1710 engine, which produced just 1,040 horsepower and was hardly powerful compared to the P-40’s peer fighters. Eventually, the engine was upgraded to a 1,200 horsepower Allison or a 1,400 horsepower Packard Merlin, each of which was more capable and allowed for better performance at high altitude.
The P-40 Goes to War
The P-40 was excellent with respect to its turning radius; it could out-turn most of its adversaries in the North African and Russian theaters. However, in the Pacific Theater, the Japanese Mitsubishi A6M Zero and Nakajima Ki-43 Hayabusa could easily out-turn the P-40 at low speeds. Accordingly, P-40 pilots were advised against engaging in Japanese fighters for long duration dogfights, in which pilots tended to bleed energy and engage at lower speeds—conditions which favored the tighter-turned Japanese fighters.
The P-40 did get high marks for ruggedness and durability. The aircraft’s semi-modular design allowed for easy maintenance in the field, which was especially helpful while deployed to the far corners of the Earth. The P-40 was structurally very strong, with a five-spar wing design that allowed the aircraft to pull high-G maneuvers, survive mid-air collisions, and even record some ramming attack victories.
For armament, the P-40 relied on six 0.5-inch M2 Browning machine guns, all situated in the wings. The P-40 could also carry up to 2,000 pounds worth of bombs on hard points under the fuselage and wing.
In all, the P-40 proved itself a worthy and rugged fighter. While not as cutting-edge or impressive as the P-51, Supermarine Spitfire, or Messerschmitt Bf 109, the P-40 played an important role in the Allied victory.
