Tthe 마틴 B-57 캔버라 1953 년 미국 공군 (USAF)과 함께 서비스에 들어간 미국 내장 트윈 제트 전술 폭격기 및 정찰기입니다. B-57은 Glenn L. Martin Company에서 제조 한 British English Electric Canberra의 라이센스 제작 버전입니다. 초기 마틴 빌드 모델은 영국이 만든 모델과 매우 유사했습니다. 마틴은 나중에 미국에서 조달 한 대량의 부품을 통합하도록 설계를 수정하고 항공기를 여러 가지 변형으로 생산했습니다.
Tthe 마틴 B-57 캔버라was a rare example of a British aircraft design (the English Electric Canberra) being licensed and mass-produced in the United States. While it excelled as a tactical bomber and “night intruder,” theEB-57Bwas a specialized electronic warfare (EW) conversion. These aircraft were packed with jammers and sensors, used primarily to train air defense crews by simulating enemy electronic attacks—blinding radars and disrupting communications to keep the “defenders” sharp.

Design Features: The Art of Jamming
The “Tandem” Cockpit:Unlike the original British version where the navigator sat in a dark hole in the fuselage, Martin redesigned the B-57B with a fighter-style tandem cockpit under a long, continuous canopy. This gave the Electronic Warfare Officer (EWO) better situational awareness.
Rotary Bomb Bay:The B-57 featured a unique rotary bomb bay door. On the EB-57B, instead of bombs, this bay often housed massive internal electronic jamming suites and cooling systems for the high-powered vacuum tubes of the era.
Wing-Mounted ECM Pods:To expand its frequency coverage, the EB-57B frequently carried specialized Electronic Countermeasures (ECM) pods on its underwing pylons, allowing it to simulate a wide variety of Soviet radar-interference signatures.
Wright J65 Engines:The US versions swapped the British Rolls-Royce Avons for the Wright J65 (a licensed Armstrong Siddeley Sapphire). These provided excellent low-altitude performance, essential for the B-57’s original mission as a “night intruder.”
Cold War Service & The “Aggressors”
Electronic Aggressor Squadrons:The EB-57B was the backbone of the 17th and 19th Defense Systems Evaluation Squadrons. They flew against US and NATO radar sites to find “holes” in the defense network and train operators to “burn through” enemy jamming.
Vietnam Service:While the EB-57B was a trainer, its bomber brother, the B-57B, was a legend in Vietnam, notably during the “Patricia Lynn” reconnaissance missions and as the first US jet bomber to be deployed to the conflict.
Longevity:The Canberra airframe was so robust that some highly modified versions (WB-57F) arestill flying todayfor NASA, used for high-altitude atmospheric research and satellite sensor testing.
The “Whistling Wheelbarrow”:Ground crews gave the Canberra this nickname due to the high-pitched whine of its engines at idle and its tricycle landing gear configuration.
