The B-47 Stratojet: a sleek, swept-wing icon of the Cold War, and a pivotal aircraft in aviation history. This jet-powered bomber, developed in secrecy after WWII, was the backbone of the US Strategic Air Command (SAC) during the tense nuclear standoff with the Soviet Union. Capable of speeds exceeding 600 mph and carrying a massive nuclear payload, the B-47 was a formidable deterrent. But beyond its raw power, the Stratojet was a marvel of engineering, pushing the boundaries of aerodynamic design and jet propulsion.Its revolutionary swept-wing configuration, inspired by captured German data, was a radical departure from the straight-wing bombers of the past, allowing for unprecedented speed and maneuverability at high altitudes. Six powerful General Electric J47 turbojet engines, slung in pods beneath the wings, provided the thrust needed to carry its heavy bomb load over intercontinental distances.This wasn’t just a war machine; it was a technological leap forward. Did you know the B-47’s thin, flexible wings were designed to flex upwards by as much as 17 feet during flight? Or that it pioneered the “bicycle” landing gear configuration, with two main gear units in tandem, requiring outrigger wheels on the inboard engine pods for stability on the ground? These innovations, while seemingly odd, were critical to the aircraft’s performance.The B-47’s development wasn’t without its challenges. Early models suffered from engine problems, and its high landing speed and unique handling characteristics demanded exceptional skill from its pilots. In fact, the aircraft was so demanding that it earned the nickname the “Widow Maker”.Among the many test pilots who tamed this beast was the legendary Colonel Walter J. Boyne, USAF (later Director of the National Air and Space Museum). Boyne, a highly decorated pilot and prolific aviation author, flew the B-47 during its early operational years and contributed significantly to understanding its complex flight characteristics. He later recounted his experiences, highlighting the B-47’s crucial role in maintaining nuclear peace during a very dangerous period. There was a special program named “Operation High Flight,” where the crew members had to maintain their flight proficiency on the airplane, especially with refueling and long-range flying.Another thing that was not known by many was that the B-47 program was not just about building bombers. It also gave rise to the RB-47, a specialized reconnaissance variant that flew daring spy missions deep into Soviet airspace, gathering crucial intelligence during the height of the Cold War. There were also several other variants, like the EB-47 or the WB-47, that were built for different roles.While ultimately overshadowed by the larger and more powerful B-52, the B-47 Stratojet remains a symbol of American ingenuity and a critical chapter in the history of the Cold War. It was a groundbreaking aircraft that paved the way for future generations of jet bombers and left an indelible mark on aviation. Join us as we explore the legacy of this remarkable machine, the pilots who flew it, and its vital role in a world on the brink.General characteristicsCrew: 3Length: 107 ft 1 in (32.64 m)Wingspan: 116 ft 0 in (35.36 m)Height: 28 ft 0 in (8.53 m)Wing area: 1,428 sq ft (132.7 m2)Aspect ratio: 9.42Airfoil: NACA 64A(.225)12 mod (BAC145)Empty weight: 80,000 lb (36,287 kg)Gross weight: 133,030 lb (60,341 kg)Max takeoff weight: 221,000 lb (100,244 kg)Zero-lift drag coefficient: 0.0148 (estimated)zero-lift drag coefficient area: 21.13 ft2 (1.96 m2)Powerplant: 6 × General Electric J47-GE-25 turbojet engines, 7,200 lbf (32 kN) thrust eachPerformanceMaximum speed: 607 mph (977 km/h, 527 kn)Cruise speed: 557 mph (896 km/h, 484 kn)Combat range: 2,013 mi (3,240 km, 1,749 nmi) with 20,000 lb (9,100 kg) bombloadFerry range: 4,647 mi (7,479 km, 4,038 nmi) with underwing tanksService ceiling: 40,500 ft (12,300 m)Rate of climb: 4,660 ft/min (23.7 m/s)Wing loading: 93.16 lb/sq ft (454.8 kg/m2)Thrust/weight: 0.22ArmamentGuns: 2 × 20 mm (0.787 in) M24A1 autocannon in a remote controlled tail turret withBombs: 25,000 lb (11,340 kg) of ordnance, including:2 × Mk15 nuclear bombs (3.8 megaton yield each), or4 × B28 nuclear bombs (1.1–1.45 megaton yield each), or1 × B41 nuclear bomb (25 megaton yield), or1 × B53 nuclear bomb (9 megaton yield), or28 × 500 lb (227 kg) conventional bombs
