19 April 1942: On the day following the Halsey-Doolittle Raid, Lieutenant Colonel James Harold Doolittle, United States Army Air Forces, the leader of the B-25 strike force, was advanced two grades to the rank of brigadier general.
(Doolittle had been promoted to lieutenant colonel on 2 January 1942, and served just 108 days in that grade. He did not hold the rank of colonel.)
Upon his return to the United States Brigadier General Doolittle was presented with the Medal of Honor by President Franklin D. Roosevelt in a ceremony at The White House.
His next assignment was to the Eighth Air Force as it prepared to deploy to Europe.
18 April 1942: Task Force 16, under the command of Vice Admiral William F. Halsey, Jr., U.S. Navy, approached the Japanese islands on a daring top secret joint Army-Navy attack.
Planning for the attack began in January 1942 under orders from Admiral Earnest J. King, Commander-in-Chief United States Fleet. Captain Donald B. Duncan, U.S. Navy, was responsible for the plan.
The operation was carried out by Task Force 16 under the command of Vice Admiral William F. Halsey, Jr., United States Navy. Task Force 16 consisted of two aircraft carriers, USS Enterprise (CV-6) and USS Hornet (CV-8), four cruisers, eight destroyers and two oilers. There were two air groups, consisting of eight squadrons of 54 fighters, 72 dive bombers, 36 torpedo bombers, and one squadron of of 16 medium bombers. Lieutenant Colonel James Harold (“Jimmy”) Doolittle, U.S. Army Air Corps, commanded the Strike Group of North American Aviation B-25 Mitchell bombers aboard Hornet.
With the land-based Army bombers secured to Hornet‘s flight deck, her own fighters had been struck below. The air group from Enterprise provided Combat Air Patrol for the task force. The plan was to bring the B-25s within 400 miles (645 kilometers) of Japan, have them take off and carry out the attack, then fly on to airfields in Chinese territory.
At 0500 hours, the task force was sighted by a Japanese picket boat while still over 700 miles (1,127 kilometers) away from Tokyo. At 0644 another vessel was spotted by the task force. Fearing that surprise had been lost, Admiral Halsey ordered the bombers launched while still 623 miles (1,003 kilometers) from land.
The sixteen B-25s were successfully launched from Hornet and headed for their assigned targets. The lead airplane, B-25B serial number 40-2344, was flown by Lieutenant Colonel Doolittle.
Single B-25s attacked targets in the cities of Tokyo, Nagoya, Osaka and Kobe.The first bombs were dropped on Tokyo at 1215 local time. This was the first offensive operation carried out by the United States of American against the Empire of Japan during World War II.
The actual destructive effect of the attack was minimal. It had been hoped that there would be psychological effects on the citizenry, however the arrival of the American bombers coincided with an ongoing air raid drill, and many thought it was all part of the drill.
Militarily, however, the attack was a stunning success. Four Japanese fighter groups, needed elsewhere, were pinned down at home, waiting for the next attack.
Not a single B-25 was lost over Japan. One landed in Vladivostok where the crew and airplane were interred by the “neutral” Soviets, but they eventually were able to get home. The rest continued on toward China, though without enough fuel to reach their planned destinations. Four B-25s made crash landings, but the crews of the others bailed out into darkness as their planes ran out of gas.
Five of the airmen were killed. Eight were captured by the Japanese, two of whom were executed by a military court, and another died in prison.
For his leadership in the air raid, James Harold Doolittle was promoted to the rank of Brigadier General, and was awarded the Medal of Honor by President Franklin D. Roosevelt. General Doolittle’s Medal is in the collection of the National Air and Space Museum.
The President of the United States of America, in the name of Congress, takes pleasure in presenting the Medal of Honor to Brigadier General [then Lieutenant Colonel] James Harold Doolittle (ASN: 0-271855), United States Army Air Forces, for conspicuous leadership above the call of duty, involving personal valor and intrepidity at an extreme hazard to life while Commanding the First Special Aviation Project in a bombing raid of Tokyo, Japan, on 18 April 1942. With the apparent certainty of being forced to land in enemy territory or to perish at sea, General Doolittle personally led a squadron of Army bombers, manned by volunteer crews, in a highly destructive raid on the Japanese mainland.
War Department, General Orders No. 29 (June 9, 1942), Amended by Department of the Army G.O. No. 22 (1959) & No. 4 (1960)
27 March 1942: After three weeks of intensive training at Eglin Field, Florida, twenty-two North American Aviation B-25B Mitchell twin-engine medium bombers of the 34th Bombardment Squadron (Medium), 17th Bombardment Group (Medium), U.S. Army Air Force, under the command of Lieutenant Colonel James Harold Doolittle, completed a two-day, low-level, transcontinental flight, and arrived at the Sacramento Air Depot, McClellan Field, California, for final modifications, repairs and maintenance before an upcoming secret mission: The Halsey-Doolittle Raid.
The B-25 had made its first flight 19 October 1940 with test pilot Vance Breese and engineer Roy Ferren in the cockpit. It was a mid-wing airplane with twin vertical tails and retractable tricycle landing gear. The first 8–10 production airplanes were built with a constant dihedral wing. Testing at Wright Field showed that the airplane had a slight tendency to “Dutch roll” so all B-25s after those were built with a “cranked” wing, using dihedral for the inner wing and anhedral in the wing outboard of the engines. This gave it the bomber’s characteristic “gull wing” appearance. The two vertical stabilizers were also increased in size.
The B-25B Mitchell was operated by a crew of five: two pilots, a navigator, bombardier and radio operator/gunner. It was 53 feet, 0 inch (16.154 meters) long with a wingspan of 67 feet, 7.7 inches (20.617 meters) and overall height of 15 feet, 9 inches (4.801 meters). The The B-25B had an empty weight of 20,000 pounds (9,072 kilograms) and the maximum gross weight was 28,460 pounds (12,909 kilograms).
The B-25B was powered by two air-cooled, supercharged, 2,603.737-cubic-inch-displacement (42.668 liter) Wright Aeronautical Division Cyclone 14 GR2600B665 (R-2600-9) two-row 14-cylinder radial engines with a compression ratio of 6.9:1. The engines had a Normal Power rating of 1,500 horsepower at 2,400 r.p.m., and 1,700 horsepower at 2,600 r.p.m. for takeoff, burning 100-octane gasoline. These engines (also commonly called “Twin Cyclone”) drove three-bladed Hamilton Standard Hydromatic variable-pitch propellers through 16:9 gear reduction. The R-2600-9 was 5 feet, 3.1 inches (1.603 meters) long and 4 feet, 6.26 inches (1.378 meters) in diameter. It weighed 1,980 pounds (898 kilograms).
The medium bomber had a maximum speed of 322 miles per hour (518 kilometers per hour) at 15,000 feet (4,572 meters) and a service ceiling of 30,000 feet (9,144 meters).
It could carry a 3,000 pound (1,361 kilograms) bomb load 2,000 miles (3,219 kilometers). Defensive armament consisted of a single Browning M2 .30-caliber machine gun mounted in the nose, two Browning M2 .50-caliber machine guns in a power dorsal turret, and two more .50s in a retractable ventral turret. (The lower turrets were removed from all of the Doolittle B-25s.)
North American Aviation, Inc., built 9,816 B-25s at Inglewood, California, and Kansas City, Kansas. 120 of these were B-25Bs.
14–15 January 1935: James Harold Doolittle set a Fédération Aéronautique Internationale (FAI) World Record for Speed Over a Recognised Course of 329.98 kilometers per hour (205.04 miles per hour).¹
Doolittle took off from Union Air Terminal, Burbank, California, at 5:27 p.m., Pacific Standard Time, 14 January (8:27 p.m., Eastern Standard Time). Also on board were Mrs. Doolittle and Robert Adamson (1871–1935), an executive with the Shell Oil Company.
The airplane was an Airplane Development Corporation V-1A Special, NC13770, owned by American Airlines and leased to Shell.
Doolittle crossed overhead Floyd Bennett Field at 8:26 a.m., Eastern Standard Time, 15 January. He then landed at Newark Airport, New Jersey, at 8:34½ a.m. The flight from Burbank to Brooklyn had a duration of 11 hours, 59 minutes, and broke a record set two months earlier by Eddie Rickenbacker.
The Airplane Development Corporation Model V-1A (commonly known as the “Vultee V-1A”) was a large, all-metal, single-engine, low-wing monoplane with retractable landing gear. The V-1A was designed as a high-speed airliner and was of full monocoque construction. It could be flown by one or two pilots and carry up to eight passengers.
The V-1A was designed by Gerard Freebairn Vultee and Richard Palmer,² based on an earlier design by Vultee and Vance Breese, who were working for the Airplane Development Corporation, which they had founded in 1932, but which had been acquired by the Cord Corporation. The prototype made its first flight 19 February 1933 with test pilot Marshall Headle at the controls.
NC13770, serial number 24073, was the eighth V-1A built, and was one of the original ten ordered by American Airlines. The V-1A was 37 feet, 0 inches (11.278 meters) long with a wingspan of 50 feet, 0 inches (15.240 meters) and height of 10 feet, 2 inches (3.099 meters). The wings had root chord of 11 feet, 3 inches (3.429 meters) and tip chord of 5 feet, 0 inches (1.524 meters). Total wing area was 384.0 square feet (35.675 square meters). There was 3° dihedral. The V-1A had an empty weight of 5,212 pounds (2,364 kilograms) and gross weight of 8,500 pounds (3,856 kilograms).
The Vultee V-1A was powered by an air-cooled, supercharged, 1,823.129 cubic-inch displacement (29.785 liter) Wright Aeronautical Division Cyclone 9 R-1820-F2 (R-1820-20 or R-1820-102), a nine-cylinder radial engine with a compression ratio of 6.4:1. This was a direct-drive engine with a Normal Power rating of 691 horsepower at 1,950 r.p.m., at Sea Level. It required 87-octane gasoline. The engine turned a three-blade propeller with a diameter of 10 feet, 0 inches (3.048 meters). The R-1820-F2 was 3 feet, 7-3/8 inches (1.102 meters) long, 4 feet, 5-3/4 inches (1.365 meters) in diameter, and weighed 937 pounds (425 kilograms).
The V-1A had a cruise speed of 215 miles per hour (346 kilometers per hour) and maximum speed of 235 miles per hour (378 kilometers per hour). The airplane’s service ceiling was 23,000 feet (7,010 meters). In standard configuration, it had a range of 1,000 miles (1,609 kilometers).
NC13770 was later sold to Harry Richman of Miami Beach, Florida, who christened the airplane Lady Peace. During the Spanish Civil War, the airplane was captured by the Nationalists. It was used as a transport for the Aviación Nacional Grupo 43, identified as 43-14, and named Capitán Haya. Its U.S. registration was cancelled 8 October 1937. It is believed that the airplane was scrapped in the early 1950s.

² Richard Palmer was the designer of Howard Hughes’ record setting H-1.
26 October 1925: Lieutenant James Harold Doolittle, Air Service, United States Army, won the Coupe d’Aviation Maritime Jacques Schneider (commonly called the Schneider Trophy) when he placed first flying his Curtiss R3C-2 float plane over a 217-mile (349 kilometer) course near Bay Shores on Chesapeake Bay, Maryland.
Doolittle’s average speed for the seven laps around the triangular race course was 232.57 miles per hour (374.29 kilometers per hour). The second-place airplane, a Gloster-Napier III flown by Captain Hubert Broad, averaged 199.16 miles per hour (320.52 kilometers per hour).
Doolittle also set two Fédération Aéronautique Internationale (FAI) world records during the race: World Record for Speed Over 100 Kilometers, with an average speed of 377.83 kilometers per hour (234.77 miles per hour);¹ World Record for Speed Over 200 Kilometers, 377.16 kilometers per hour (234.36 miles per hour).² On the following day, Doolittle set a third FAI record: World Record for Speed Over a 3 Kilometer Course, 395.5 kilometers per hour (245.75 miles per hour).³
A contemporary news article commented on Jimmy Doolittle’s performance:
“. . . according to reports Lieut. Doolittle’s cornering was superb, and must have been to a great extent responsible for the excellent performance. Reports from America—coming, it is thought, from a reliable source—indicate that one particular engine out of the 12 built for the Pulitzer and Schneider Trophy races proved exceptionally good, as will often happen in a batch of engines, and it is believed that this engine was fitted in Doolittle’s Curtiss-Army Racer. This fact, taken in conjunction with the masterly handling of the machine, would seem to account for the wholly unexpected average speed maintained, which was, of course, far and away ahead of the speeds of the British and Italian competitors.”

The R3C-2 was a single-engine, single-seat, single-bay biplane, equipped with pontoons for taking off and landing on water. It was built especially for air racing. Two R3Cs were built for the United States Navy and one for the Army. (The Army aircraft is identified by a Navy Bureau of Aeronautics serial number (“Bu. No.”) A-7054. It does not seem to have been assigned an Air Service serial number.) The airplane and its V-1400 engine were both built by the Curtiss Aeroplane and Motor Company, which had been founded by Glenn Hammond Curtiss. The R3C-2 was converted from the R3C-1, the land plane configuration which had been flown by Lieutenant Cyrus Bettis, AS, USA, to win the Pulitzer Trophy Race just two weeks earlier.
The RC3-2 is 22 feet long (6.706 meters), an increase of 2 feet, 3.5 inches (0.698 meters) over the R3C-1 configuration, resulting from the replacement of the fixed wheeled landing gear with the single-step pontoons. The upper wing span is 22 feet (6.706 meters), with a chord of 4 feet, 8¼ inches (1.429 meters). The lower wing span is 20 feet (6.096 meters) with a chord of 3 feet, 3¾ inches (1.010 meters). Weight empty was 2,135 pounds (968 kilograms) and maximum takeoff weight was 2,738 pounds (1,242 kilograms).
Constructed of wood, the fuselage has four ash longerons and seven birch vertical bulkheads. The framework is covered with two layers of 2-inch (51 millimeter) wide, 3/32-inch (2.38 millimeter) thick spruce strips. These were placed on a 45° diagonal from the fuselage horizontal centerline, with the second layer at 90° to the first. These veneer strips were glued and tacked to the frame. The fuselage was then covered with doped fabric. The wings and tail surfaces are also of wood, with spruce ribs and a covering of spruce strips.
The single-bay wings are wire braced and contain surface radiators made of thin brass sheeting. The radiators contained 12 gallons (45.4 liters) of water, circulating at a rate of 75 gallons (283.9 liters) per minute. By using surface radiators to cool the engine, aerodynamic drag was reduced.
The Curtiss V-1400 engine was developed from the earlier Curtiss D-12. It was a water-cooled, normally aspirated, 1,399.91-cubic-inch-displacement (22.940 liter), dual overhead cam (DOHC) 60° V-12, with a compression ratio of 5.5:1. The V-1400 was rated at 510 horsepower at 2,100 r.p.m., and could produce 619 horsepower at 2,500 r.p.m. It was a direct-drive engine and turned a two-bladed duralumin fixed-pitch propeller with a diameter of 7 feet, 8 inches (2.337 meters). The propeller was designed by Sylvanus Albert Reed, Ph.D. The V-1400 engine weighed 660 pounds (299 kilograms).
The R3C-2 had a fuel capacity of 27 gallons (102 liters). Its range was 290 miles (467 kilometers).
Jimmy Doolittle was one of America’s foremost pioneering aviators. He set many records, won air races, tested and developed new flying equipment and techniques.
He was a highly-educated military officer, having earned his Bachelor of Arts from the University of California Berkeley School of Mines, and M.S and D.Sc. degrees in Aeronautical Engineering from the Massachusetts Institute of Technology.
During World War II, Colonel Doolittle planned and led the famous Halsey-Doolittle Raid against Japan, 18 April 1942, for which he was awarded the Medal of Honor.
As a brigadier general, he commanded 12th Air Force in North Africa. Promoted to major general, he was given command of the 15th Air Force in the Mediterranean Theater, and commanded 8th Air Force as a lieutenant general, 1943–1945.
After the war, Lieutenant General Doolittle was placed on the inactive list. On 4 April 1985, by Act of Congress, James H. Doolittle was promoted to General.
