The P-39, [[Bell Aircraft]]’s most successful fighter, sported a number of new design features for the time, including tricycle landing gear and an engine mounted behind the cockpit.  Its most well-known aspect was a 37 mm cannon mounted in the nose and fired through the propeller hub.  In fact, the beginning of the fighter can be traced to a demonstration of the T-9 37 mm gun by the American Armament Corporation in early 1935.  Bell executives present were so impressed by what they saw that they instigated the design of an aircraft that could fire the gun through the propeller hub.  The position of the big gun meant that the engine had to be moved to the middle rear of the plane, and this left room for a nose wheel.

The new plane first flew in April 1938, and went into mass production in August 1939.<ref>''The World’s Great Fighters: From 1914 to the Present Day'', by Robert Jackson, Amber Books, 2001</ref>

The P-39 was powered by an Allison, 1325 hp, liquid-cooled engine.  However, the [[turbosupercharger]] was removed in the production models, hampering their performance at high altitude.  Top speed was 380 mph, and range was 1475 miles (with a centerline drop tank).  In addition to the cannon, armament consisted of two heavy machine guns in the nose and two or four machine guns in the wings. <ref>''The Illustrated Encyclopedia of Combat Aircraft of World War II'', by Bill Gunston, Salamander Military Press, 1990</ref>

The P-400 was a variant built for the [[RAF]], with a 20 mm gun in the propeller hub.  However, after a short period of operation, the RAF discovered that the fighter was not suitable for their purposes.  The USAAF took them back in late 1942, sending them to North Africa and the Pacific.  Most of the Airacobras had never even been taken out of their crates before being returned.  Several P-400s were also sent to the Soviet Union.

American P-39s were most prominent in the first year of the Pacific war, partly because Airacobras and [[P-40 Warhawk|P-40s]] were the only planes available in the first months.  They were used mainly in the ground attack role, although they could hold their own in air combat at low altitude.  The nose cannon was slow-firing and often jammed, but when it hit, it was devastating to the lightly armored Japanese planes.

When the war began and the Japanese forces swept south towards [[Australia]], P-39s were rushed into action.  In April of 1942, Airacobras of the 8th Pursuit Group were deployed on the front line in [[New Guinea]], and their first combat mission was on April 30.  13 P-39s, led by [[flying ace|ace]] and veteran of the Philippines campaign [[Boyd Wagner|Boyd “Buzz” Wagner]], performed an offensive sweep of the Japanese airfields at [[Lae]] and Salamaua.  The Americans had surprise on their side, and strafing runs took out a fuel dump, radio station, and three seaplanes at anchor.  Defending [[Mitsubishi Zero|Zeroes]] responded, and four P-39s and four Zekes were shot down in the melee.  Three of the American pilots bailed out safely and eventually made their way back to base.  Three of the Zeros were downed by Wagner himself.

In May, P-39s were involved in the defense of [[Port Moresby]], downing almost twenty of the enemy while suffering heavy losses.  P-39s saw heavy action through the rest of 1942, mainly used to provide air support to Allied forces.

By the beginning of 1944, the only Airacobras left in the theater were specialized models used for photo-reconnaissance.  All other units had been re-equipped with [[P-38 Lightning]]s or [[P-47 Thunderbolt]]s.

In 2004, the wreckage of an American P-39 was discovered deep in the jungle in [[Fiji]].  It had crashed, killing the pilot, while on a mission in late April of 1942.  The pilot’s remains were returned to the US Air Force.<ref>[http://www.taipeitimes.com/News/world/archives/2006/07/14/2003318738 Fiji hands over lost pilot’s remains]</ref>

Out of a total of over 9500 Airacobras produced, almost 5000 were supplied to the Soviet Union via [[Lend Lease]], and it was in Soviet hands that the plane scored its greatest successes.  Air combat on the Eastern Front tended to be at lower altitudes, which minimized the P-39’s disadvantages, and in the right hands, the fighter proved deadly.  Over a hundred Russian pilots, including three of the five top scorers, became Airacobra aces, and the highest scoring P-39 pilot ever was [[Hero of the Soviet Union]] Gregori Rechkalov, with an even 50 victories with the American plane, including several Bf-109s.<ref>[http://www.acepilots.com/planes/soviet_p39_airacobra.html Soviet P-39 Aces]</ref>

With its 37 mm cannon, the P-39 was highly effective against ground targets as well, although, contrary to popular belief, it was not a tank-buster.<ref>[http://www.chuckhawks.com/airacobra_iron_dog.htm Airacobra or Iron Dog?, The Obscure Career of Bell’s P-39 in the Soviet Union]</ref>
