On 18 April 1942, airmen of the US Army Air Forces, led by Lt. Col. James H. (Jimmy) Doolittle, carried the Battle of the Pacific to the heart of the Japanese empire with a surprising and daring raid on military targets at Tokyo, Yokohama, Yokosuka, Nagoya, and Kobe. This heroic attack against these major cities was the result of coordination between the Army Air Forces and the US Navy, which carried the sixteen North American B-25 medium bombers aboard the carrier USS Hornet to within

The Mission and the Man In January 1942, Gen. Henry "Hap" Arnold selected Lt. Col. James Doolittle to lead Special Aviation Project No. 1, the bombing of Japan. Doolittle, who enlisted in the Army in 1917, became a flying cadet and received his commission in 1918. In the late 1920s and the early 1930s, he won the prestigious Schneider, Bendix and Thompson aviation trophies. He made the first blind flight in 1929 during which he took off, flew and landed while being completely dependent upon aircraft instruments. Doolittle left the Army Air Corps in 1930, but when war appeared imminent, in 1940 he returned to active duty. Although the Doolittle Raid of April 18, 1942, caused only minor damage, it forced the Japanese to recall combat forces for home defense, raised fears among the Japanese civilians, and boosted morale among Americans and our Allies abroad.
North American B-25B Mitchell The B-25 medium bomber was one of America's most famous airplanes of World War II, and more than 9,800 were built. It saw duty in every combat area, being flown by the Dutch, British, Chinese, Russians and Australians in addition to U.S. forces. Although the B-25 was originally intended for level bombing from medium altitudes, Pacific Theater aircrews often used it at low level to attack Japanese airfields and strafe and skip bomb enemy shipping.
The U.S. Army Air Forces chose the B-25 for the Doolittle Raid because it was the only aircraft available with the required range, bomb capacity and short takeoff distance. The B-25Bs and 24 trained volunteer crews came from the 17th Bombardment Group, Pendleton Field, Ore.
The airplane on display at the museum is a B-25D rebuilt by North American to the configuration of a B-25B used on the Tokyo Raid. It was flown to the museum in April 1958.
The Training The crews selected for the mission received their training at Eglin Field, Fla. Lt. Henry L. Miller, a Navy pilot from Pensacola Naval Station, provided assistance on how to take off within 300 feet, the available distance on the carrier USS Hornet. The crews also practiced cross-country and night flying, navigating without radio references or landmarks, low-level bombing and aerial gunnery. They completed their training in mid-March and later flew to San Francisco to board the carrier.
The Bombsight Instead of the Norden bombsight, which was ineffective at low altitudes, Capt. C. Ross Greening, pilot and armament officer for Doolittle's group designed a replacement bombsight (seen in the nose of the aircraft). This bombsight was connected to the cockpit through the pilot direction indicator, allowing the bombardier to give the pilot aircraft turn directions without relying on voice communication. Using materials costing 20 cents, the metal working shops at Eglin Field manufactured the bombsights.
The Aircraft Carrier The newly-built aircraft carrier USS Hornet was chosen to carry Doolittle's B-25s toward Japan. In March it sailed to Alameda Naval Air Station near San Francisco to load the Army Air Forces aircraft, 72 officers and 64 enlisted men. On April 2, 1942, not wanting to sail at night because of an inexperienced crew, the Hornet's captain, Marc A. Mitscher, left for the secret mission in broad daylight.
