History of the Curtiss P-40 Warhawk
The Curtiss P-40 "Warhawk" series of fighter jets is a further development of the Curtiss P-36 "Eagle" series (see elsewhere on this page). The Warhawk became the legendary aircraft of the famous American Volunteers (AVG) fighting the Japanese in China and earned the nickname "Flying Tigers". The P-40 was often replaced by new, upgraded models as the war progressed, but it remained one of the most important Allied fighter jets at the start of World War II - used by a desperate US, UK and Soviet Union.
During the Japanese attack on Pearl Harbor on December 7, 1941, a pair of P-40s piloted by American pilots George Welch and Ken Taylor successfully lifted off, while Soviet pilot Nikolai Fyodorovich Kuz Netsov, Peter Pokryshev and Stephen Novichkov all became ace pilots in their Lend-Lease P-40s. P-40 is fine. A solid shooting platform at the time, limited by the number of productions and the economic needs of the war.
Ultimately, technological developments found in upcoming fronts like the Grumman F6F Hellcat and Vought F4U Corsair drive the P-40's utility and advantages.
From 1939 to 1944, approximately 13,738 P-40s were produced. Operators include Australia, Brazil, Canada, China (Taiwan), Egypt, Finland, France, Indonesia, Netherlands, New Zealand, Poland, South Africa and Soviet Union, Turkey, United Kingdom and United States.
Some fell into the Imperial Japanese Army and were reinstated to fight for their new owners.
The P-40 Warhawk is not a great aircraft in any class, but can be a deadly combat machine in well-trained hands. It deploys an impressive 4 x .50 caliber Browning M2 heavy machine guns (up to 200 to 235 rounds each) in its nose and wings.
This was later complemented by the airframe's ability to carry a modest bomb load to increase the workload of the wartime workhorse. The Warhawk featured a liquid-cooled inline-piston engine at the peak of its design, unlike the more popular air-cooled radial aircraft in many fighter types at the time, including the P-36 Hawk.
The engine consists of an Allison V12 engine with over 1,000 horsepower.
Although the French Air Force ordered the P-40 early in the war, the eventual fall of France forced the order to be moved to Britain, where it was quickly renamed the Tomahawk. The British version was fitted with an off-the-shelf .303 machine gun instead of the .50 caliber type. Some Tomahawk models ended up in the hands of American Volunteer troops stationed in China, which in turn provided more and more aerial victories for looting Japanese fighters and bombers. Early P-40 models included the P-40B and P-40C, as well as the Tomahawk I, Tomahawk IIA, and Tomahawk IIB.
These services ran from 1941 to 1943, mainly through North Africa, China/Myanmar/India, the Philippines and Pearl Harbor. During the "Continuing War", Soviet troops fought over the Eastern Front and Finland.
The P-40B variant introduced cockpit and fuel tank armor, while the C variant featured a fully armored fuel system, reducing speed.
Further improvements to the P-40 product line resulted in the "D" model, which improved the performance specifications of the Allison piston engine. By this time, the armament had grown to a 6 x 12.7mm machine gun, and an optional undercarriage bomb rack was added, allowing the deployment of a 500-pound bomb, increasing the aircraft's versatility. The hood is slightly modified.
In addition to the diverted French Warhawks/Tomahawks, the British ordered their own P-40D models, naming them "Kittyhawk". As such, notable successors include the P-40D, P-40E, Kittyhawk Mk 1 and Kittyhawk Mk Ia.
These served from 1942 to 1943 and fought for New Guinea, Guadalcanal, Kokoda, Milne Bay, Darwin, North Africa and China.
From 1942 to 1942, the P-40K, P-40M and Kittyhawk Mk III were all seen in the war. The rear wing of the K model has been improved and has a larger area, while the rear wing of the M model is overall lengthened. These serve Guadalcanal, Kokoda, Milne Bay and Darwin.
The P-40F, P-40L, Kittyhawk Mk II and Kittyhawk Mk IIa introduced the Packard-Merlin engine and lost the top mounted engine air intake. The armament varies among the new brands, and some have elongated hulls.
These airframes flew over North Africa, the Mediterranean and the Pacific in 1943 with the U.S. and Free French Air Forces.
The P-40N, Kittyhawk Mk IV and Warhawk series were seen over the Mediterranean and Southwest Pacific theaters in 1943-1944. These features are a revised rear cockpit section that promises improved situational awareness. The elongated hull promotes more internal volume and stability.
Some versions lack wing guns to save weight.
As a result, the Warhawk front was increasingly overtaken by a new generation of enemy fighters in the war. Regardless, the Warhawk, in its various guises, continued to thrive wherever it saw service in the final weeks of the conflict, cementing its status as one of the classic American fighter jets of WWII.
