Curtiss P-40 Warhawk

Curtiss P-40 Warhawk

The 1944 Curtiss P-40 was conceived as a pursuit aircraft and was agile at low and medium altitudes but suffered from a lack of power at higher altitudes

The single-seat Curtiss P-40 Warhawk was obsolete when it was drafted for service at the start of World War II. But it was the best fighter that the United States had available in large numbers, according to a report at the Museum of Flight. Despite continued improvements, the P-40 never equaled the capabilities of its German or Japanese adversaries. But it had one priceless advantage, “It was available and being efficiently mass-produced when needed most.”

The solid and reliable Warhawk was an effective weapon when its strengths were leveraged: diving passes and rapid departure without engaging in a turning dogfight with more agile opponents.

According to Airplane-Online.com, the P-40 was a descendant of the “Hawk” line produced by the Curtiss-Wright Aircraft Corp. in the 1930s and 1940s. It shared certain design elements with its predecessors, the Hawk and Sparrowhawk.

The all-metal fighter was first flown in 1938, and the P-40 was kept in production until 1944. The P-40 was the third most-produced American fighter, after the P-51 Mustang and P-47 Thunderbolt.

Warhawk in Wartime

With its six .50-caliber Browning machine guns and a 700-pound bombload (one 500-pound and two 100-pound bombs), the P-40 served in all theaters of operation. The U.S., Britain, Canada, Australia, New Zealand, Free French, South Africa, and Russia flew the Curtiss fighter.

“The British called it the Tomahawk (B and C models) and Kittyhawk (D and E models). The F through R versions were known as Warhawks in U.S. service. The N model had decreased fuel capacity and increased armor, along with other minor system changes, relative to its predecessors.

“The most famous P-40 unit was undoubtedly the American Volunteer Group, better known as the ‘Flying Tigers.’ Painted with a shark-mouth face, the P40 had great success flying the plane in China and Burma in early 1942.

In the hands of a skilled pilot, the P-40 could exceed its limitations and out-maneuver and out-fight anything in the sky, Flying Tiger ace David L. “Tex” Hill said in 2005 interview for DefenseMediaNetwork.com.

“It was sturdy and handled well, except in a spin, but you never piloted a P-40 without wishing you had something a little better,” Hill said.

P-40 at Pearl Harbor

P-40s engaged Japanese aircraft at Pearl Harbor and in the Philippines in December 1941. They also served in North Africa in 1943 with the 99th Fighter Squadron, the first African American U.S. fighter unit.

Though often slower and less maneuverable than its adversaries, the P-40 Warhawk earned a reputation in battle for extreme ruggedness. It served throughout the war but was eclipsed by more capable aircraft.

More than 13,738 P-40 fighters were built from 1939-1944 at the Curtiss plant in Buffalo, Ny.

NOTE: This is another image from my dad, Paul Smith Maynard, who worked four decades in aviation as an engineer. Dad began his career in about 1943 after graduating from West Virginia University. He started with the Curtiss-Wright Corp., an early pioneer in making flying machines. He went on to work at North American Aviation and Rockwell International.

My dad, Paul Smith Maynard, worked for nearly four decades in aviation as an engineer. His specialty was metals, or metallurgy. Among his tasks was to determine at what point a metal part would fail. He experimented with new, lightweight metals and honeycombed metals that were lighter but strong. He evolved into rocketry, so I consider my dad a rocket scientist, though he would decline that attribute.

Dad began his career in about 1943 after graduating from West Virginia University. He started with Curtiss-Wright Corp., an early pioneer in making flying machines. It was founded by Glenn Curtiss, the father of naval aviation, and the Wright brothers, renowned for history’s first flight. Dad worked at the plant in Columbus, Ohio, where I was born in 1954.

Post-World War II, Curtiss-Wright shut down its Aeroplane Division in 1948 and sold the assets to North American Aviation. Dad was among the assets moved to NAA, which was a leader in aerospace contracts. It eventually would merge again and become Rockwell International, also in Columbus.

Occasionally, dad would bring home glossy PR photos of airplanes and prototype or maybe a chunk of some special metal. Lately, I’ve been going through his boxes of work paperwork and found a trove of early warplanes and other prototypes from Curtiss-Wright to Rockwell.

Among the pictures was this black-and-white image of a 1917 Curtiss Goupil Duck on floats. It emerged during a pissing match between Glenn Curtiss and the Wright Bros. The Wrights felt that certain elements of wing design fell under their patent of 1906, based on “wing warping.”

The Patent Battle

With their patent, the Wrights hoped to gain a monopoly on manned flight. The patent would require anyone building aircraft to pay a royalty to them. It is a fascinating story, well told by Airways magazine.

In 1908, Glenn Curtiss sought to circumvent the Wright’s patent by using ailerons, rather than wing warping. Ailerons use moveable flaps in the wings, which are considered more efficient and simpler for lateral control.
Among my dad’s photos was this 1917 Curtiss Goupil Duck, which used a design by French engineer Alexandre Doupil’s birdlike monoplane glider from 1883.

The plane was never developed. At the start of World War I, the U.S. government persuaded Wright to release the patent for combat aircraft to be developed.
