Martin B-57 airplane model. After the Korean Conflict began in 1950, the U. S. Air Force looked for a jet-powered medium bomber to replace the aging Douglas B-26 Invader. Korean war experience revealed an urgent USAF need for a high-performance jet-powered night-intruder aircraft capable of precise nighttime and bad-weather weapons delivery on moving targets located hundreds of miles from home base. The need was considered so pressing that the time usually required for development of a new aircraft was deemed unacceptable. Hence, an existing "off the shelf " aircraft was sought to fill the mission requirements. From a number of candidate vehicles, including the previously discussed North American B-45 Tornado, the English Electric Canberra bomber was selected to fill the USAF night-intruder role. In March 1951, the USAF contracted with the Glenn Martin Company to build the Canberra in the United States under a licensing agreement with English Electric. The first Canberra in American colors flew in 1951 with the first American built Canberra or Intruder in 1953. The Martin-built B-57 made its first flight on July 20, 1953. When production was terminated in 1959, a total of 403 Canberras had been produced for the USAF.
