Martin B-57 Canberra
Design and Development
At the outbreak of the Korean War in 1950, the USAF found itself in dire need of an all-weather interdiction aircraft. The existing inventory of piston-engined Douglas B-26 Invaders had been dispatched in this capacity at the very start of the conflict; however, within only a few months within the theatre, the B-26 had suffered a very high rate of attrition and successes with the type were typically limited. In response to these needs, the USAF requested the British government to provide a private demonstration of the English Electric Canberra, a newly developed jet-powered bomber. On 17 August 1950, the Canberra demonstration was performed at RAF Burtonwood, Warrington, Cheshire, England; during the following month, a team of US test pilots and engineers visited English Electric's Warton factory to perform a series of flight tests and a detailed technical assessment of the aircraft.
On 16 September 1950, the USAF formally issued a request for a jet-powered bomber; the sought aircraft had to possess a top speed of 630 mph (1,020 km/h), ceiling of 40,000 feet (12,190 m), and range of 1,150 miles (1,850 km). Full all-weather capability and a secondary reconnaissance role also had to be included in the design. The American contenders included the Martin XB-51, the North American B-45 Tornado and AJ Savage. To expedite the process, only projects based on existing aircraft were considered and, unusually, the service considered foreign aircraft. These included the Canadian Avro Canada CF-100 and the British English Electric Canberra, which had not yet officially entered service with the Royal Air Force (RAF). Aviation authors Bill Gunston and Peter Gilchrist commented that "It seems likely that this first batch of trials convinced the Americans that the Canberra was ideal for the job, but in order to satisfy the US Senate a competitive evaluation of all likely contenders had to be arranged"

Martin B-57 Canberra
The Martin B-57 Canberra is an American-built, twinjet tactical bomber and reconnaissance aircraft that entered service with the United States Air Force (USAF) in 1953. The B-57 is a license-built version of the British English Electric Canberra, manufactured by the Glenn L. Martin Company. Initial Martin-build models were virtually identical to their British-built counterparts; Martin later modified the design to incorporate larger quantities of US-sourced components and produced the aircraft in several different variants.

The B-57 Canberra holds the distinction of being the first jet bomber in U.S. service to drop bombs during combat. The Canberra was used extensively during the Vietnam War in a bombing capacity; dedicated versions of the type were also produced and served as high-altitude aerial reconnaissance platforms (the Martin RB-57D Canberra), and as electronic warfare aircraft. The B-57 Canberra was also sold to export customers abroad; further combat use was seen by the Pakistani Air Force during the Indo-Pakistani War of 1965 and the Indo-Pakistani War of 1971.
