The Martin B-57 Canberra was created for the USAF back in 1953 to function as their tactical bomber and photo-reconnaissance aircraft. The organization behind the production of this aircraft under license from the first producer, English Electric, was Glenn L. Martin.

Development

The original versions of the Martin B-57 Canberra were like in the British-made Canberra, but then Martin made numerous modifications to make the aircraft a more American one. 

In September 1950, the USAF put out a requirement for a new attack aircraft designed around a serviceable bomb load and speed. Turbojet engines were to be utilized for propulsion to accomplish the desired performance.

Specifications needed a speed of about 630 miles per hour along with a range out to 1,150 miles, as well as a service peaking near forty thousand feet. That would make the aircraft a difficult target for interception by the ground-based fire or energy, offering the design more impunity over the battlefield in a tactical bomber role. 

Of the submissions received, the British English Electric Canberra was shockingly picked over the local Martin XB-51 bomber prototype. The Martin B-57 Canberra itself was a record-setting, with two engines, multi-crew bomber whose ordnance-hauling capabilities and performance played well into the standing USAF requirement. 

Orders and Deliveries

The Martin B-57 Canberra made its very first flight in July 1953, and by the time the production finished in 1959, a total of 403 versions were created. It readily adapted to different roles, including toss bombing for nuclear weapons and testing the strange Low Altitude Bombing System (LABS). 

Canberra functioned with distinction along with the USAF for over three decades despite its first WWII technology. Scheduled to be retired in the late 1950s, a set of crises kept the Martin B-57 Canberra in the Air Force inventory, which involved service over the Vietnam War up to 1983. 

Design

The Martin B-57 Canberra was enhanced to make the B-57B have a more UDS touch. Thus, the tandem seating was launched for the two crew members: one for the navigator and one for the pilot, together with an all-new canopy.

The airbrakes were changed from being under the wings to being under the fuselage. 

Engines

The first Martin B-57 Canberra was picked as B57A that had the similarity to their British counterparts, as they’re geared with two of the Armstrong Siddeley Sapphire engines that were also created locally in America under the Wright Company license. 

However, the B-57B model was run by two of the Wright J65 turbojet engines, each of which designed a thrust of 7220 pounds. That enabled the Martin B-57 Canberra to fly at a very top speed of 598 mph while cruising speed was nearly 475 mph. 

Performance

Three of Martin B-57 Canberra fly today along with NASA for environmental and weather study for more than sixty years after the plan first flew. The airplane was picked for its all-weather and high-altitude capabilities, capacity to fly night and day, as well as its 2,500-mile range.
