Martin B-57 Canberra

The B-57 was a twin-engine jet bomber operated by the U.S. Air Force, built by the Glenn L. Martin Company. It was an American-built version of the British English Electric Canberra, produced under license, and entered U.S. service in the 1950s. It was notable as the first foreign-designed combat aircraft to be adopted and manufactured in quantity in the United States after World War II.

The B-57 was developed as a tactical bomber and reconnaissance aircraft, prized for its good performance at altitude and its versatility. Martin produced a number of variants, including specialized high-altitude reconnaissance versions with greatly extended wingspans for surveillance and weather research.

The aircraft saw extensive combat service, most notably during the Vietnam War, where it was used for bombing and interdiction missions. Some specialized B-57 variants remained in service for many years in reconnaissance and research roles long after the standard bomber versions were retired.
