History
Created to replace the piston-engined B-26 Invader, the twin jet engine tactical bomber B-57 Canberra was produced by US aircraft company Martin in the 1950s. Derived from the British aircraft EE Canberra it was produced in several versions to perform not only bombing but recon, electronic warfare, ground attack and dive bombing duties. The B-57B, developed for bombing missions, was the main version produced. It was characterized by the adoption of a new cockpit with two crew members arranged in tandem and under-wing hardpoints able to be armed with a wide range of weapons. The first units produced were armed with eight 12.7mm machine guns installed within the wings and later substituted with four 20mm cannons.
