The North American B-25 Mitchell series of medium bombers went on to become one of the classic American aircraft designs to emerge during World War Two. Designed as early as 1939, the series was built to specifications as required by the United States Army. The B-25 would go on to gain national fame in the United States as the aircraft used by the famous "Doolittle Raiders", the end result having shown the American ability to bomb the heart of Tokyo from a USN carrier stationed in the Pacific (USS Hornet).

The B-25 was initially designed as a three-crew, high-mounted wing bomber utilizing twin Pratt & Whitney R-1830-S6C-3 radial engines. By the end of its production run, the system would be overhauled to include 5 to 6 crew members in various gun positions, a shoulder-mount wing assembly and twin Wright GR-2600-A71 radial engines. After over 9,800 were produced, the Mitchell had evolved into a host of variants that included trainers, dedicated ground strike, reconnaissance and torpedo carriers.

The more identifiable B-25's were a twin-engine design with the radials mounted underneath either wing element. The forward fuselage was of a greenhouse-type design affording the forward-located gunners and bombardiers a good field of vision. The pilot and co-pilot sat in a raised location just behind the nose assembly and had good vision forward, above and to the sides. A top dorsal turret was included and was mounted with twin .50 caliber machine guns. Waist gunner positions were added with single .50 caliber guns, as was a twin .50 caliber gun position in the tail. The B-25 made use of a powered-tricycle landing gear system and a decent internal bomb bay. Twin rudder assemblies differentiated the system from the other similar-looking twin-engine medium bombers of American design.

Initial B-25 designs limited the crew to just three, whereas a fuselage widening helped to increase width and seat the pilot and co-pilot side-by-side. Armor and self-sealing fuel tanks were already common in about 40 developmental models of the "A" variety. The "B" model would go on to feature 119 production aircraft with powered dorsal and ventral turret emplacements but the rear tail gunner position removed.

It would not be until the valuable and definitive "C" models joined the lines that the B-25 would come into its own. C-model construction would leap into the 1,600's and featured an autopiloting system, underwing hardpoints, provision for torpedo carrying and the identifiable forward-fixed 4 x .50 caliber machine gun pods on either side of the lower-front fuselage.

Following the C-models would be the very similar "D" series that varied in only being produced on a different production line facility. The next "G" models would feature a large-caliber 75mm cannon in the nose followed by "H" models with a similar gun system and upwards of 18 defensive machine guns positioned throughout the aircraft. Dedicated ground strike models were even featured with a devastating array of 8 x .50 caliber machine guns in a forward-fixed assembly mounted in the nose.

One of the sixteen North American B-25 Mitchell medium bombers that took part in the famous Doolittle Raid of 1942, 'The Ruptured Duck,' along with Doolittle's own aircraft is one of the best known of the aircraft that took part. Conceived as a way to boost the morale of a nation still reeling from the attack on Pearl Harbour, the Doolittle Raid consisted of the USAAF flying a number of B-25 Medium bombers off an aircraft carrier close to Japan, bombing Tokyo and then flying on to land in China. While material damage would be slight, the effect on morale back in America, and detrimentally in Japan, would be huge. 'The Ruptured Duck' got its name from scraping its rear fuselage on the runway during training. After bombing Tokyo the aircraft flew on to China where it crashed into the sea near Shangchow. All of the crew survived, though the pilot Lt. Ted Lawson lost a leg in the ditching.

As well as serving with the US armed forces the Royal Air Force would also use the North American B-25 Mitchell in high numbers to replace it's Douglas Boston and Lockheed Ventura aircraft and the type entered operational service with the RAF on the 22nd January 1943 when twelve aircraft supplied form both No. 98 and No. 180 Squadrons attacked the oil installations at Ghent. As well as the RAF B-25 Mitchells would serve with various air forces around the world including Canada, Holland and China.

By the time production had finished 9,984 B-25's had been built and served in various roles including reconnaissance and wing de-icing experiments and continued in service outside of the US until 1960.
