The United States was the "Arsenal of Democracy" in World War II, but even this arsenal had to get a little help from allies. The British, in fact, loaned us some of their planes during that conflict. Here are four planes we borrowed from the Brits.
1. Supermarine Spitfire
Yes, even though the United States had the P-40, P-38, P-47, P-51, F4F Wildcat, F6F Hellcat, and the F4U Corsair, they had to acquire the plane that won the Battle of Britain.
The American Spitfires mostly saw service in North Africa and Italy, according to SpitfireSite.com, until they were replaced by P-51s. United States Army Air Force Spitfires scored almost 350 kills during World War II.
The Spitfire is also notable for being the plane that got Jimmy Doolittle chewed out by Eisenhower.
2. Airspeed Horsa
Okay, this is technically a glider. Still, the United States needed a glider to bring in heavy gear for units like the 82nd and 101st Airborne Divisions. The Airspeed Horsa fit the bill with its ability to carry a lot of troops and gear, and the United States got 301 of the planes for D-Day, according to the book World War II Glider Assault Tactics.
3. Bristol Beaufighter
This was a multi-role heavy fighter, which packed a huge punch (four 20mm cannon, six .303-caliber machine guns). According to Combat Squadrons of the Air Force, the United States operated four squadrons of Beaufighters in the night-fighter role. These squadrons operated in the Mediterranean Theater of Operations, eventually switching to the P-61 Black Widow.
4. De Havilland Mosquito
This plane was very versatile, used for photo reconnaissance, as a night-fighter, as a heavy fighter, and even as a light bomber. The Army Air Force used a number of these planes in all of those roles during World War II, but historynet.com noted that most of them were crashed because this airborne hot rod was difficult to fly.
America may have missed out — the Mosquito is considered a legend.
Even today, America's importing warplanes: The A-29 Super Tucano is a Brazilian design, while the AV-8 Harrier was British.
