Design and Development
The B-47E Stratojet was designed by Boeing in response to a US Air Force requirement for a high-altitude, strategic bomber. The aircraft's design was influenced by the German Messerschmitt Me 262 jet fighter, which had been studied by American engineers after World War II. The B-47E's unique design featured a swept wing and a streamlined fuselage, allowing it to achieve high speeds and altitudes.
Key Features
The B-47E Stratojet had several key features that made it an effective strategic bomber:
- Swept Wing: The B-47E's swept wing design allowed it to achieve high speeds and stability at high altitudes.
- Streamlined Fuselage: The aircraft's streamlined fuselage reduced drag, enabling it to reach high speeds and maintain fuel efficiency.
- Six Jet Engines: The B-47E was powered by six General Electric J47 turbojet engines, which provided a combined 42,000 pounds of thrust.
- Advanced Avionics: The aircraft featured advanced avionics, including a bombing navigation system and a defensive radar system.
Operational History
The B-47E Stratojet entered service with the US Air Force in 1951 and played a significant role in the Cold War era. The aircraft was used for strategic bombing missions, reconnaissance, and as a deterrent against the Soviet Union.
Notable Missions
The B-47E Stratojet was involved in several notable missions, including:
- Operation Redwing: In 1956, a B-47E Stratojet dropped a nuclear bomb over Bikini Atoll as part of Operation Redwing, a series of nuclear tests.
- Operation Chrome Dome: In the 1960s, B-47E Stratojets were used for Operation Chrome Dome, a mission to deter Soviet aggression by maintaining a fleet of bombers in the air at all times.
