It was also adapted to a number of other missions, including photo reconnaissance, electronic intelligence and weather reconnaissance, remaining in service as a reconnaissance platform until 1969 and as a testbed until 1977. ", "DT Handbook-Handbook of Damage Tolerance", "1958 – B-47 explodes over southeast Tulsa. Between 21 March and 10 May 1956, 16 RB-47Es and five RB-47Hs operating from Thule performed overflights the length of Siberia 156 times under Project HOMERUN. About 25 surviving airframes exist in museum collections worldwide.  The J47 or "TG-190" was a redesigned version of the TG-180/J35. Small outrigger wheels on the inboard engines kept the airplane from tipping over when it was on the ground.  Boeing's B-52 Stratofortress, in contrast, generally had six crewmen, five officers and one enlisted, with more internal cabin space. It was sluggish on takeoff and too fast on landings, an unpleasant combination. Killed in the crash were Lt. Col. Lamar Ledbetter (41,98th Bomb Wing, Standardization and Evaluation division), Captain Donald J. Livingston (31, Aircraft Commander)343rd Bomb Sqdn, Lt. Thomas Hallgarth (22, Navigator)343rd Bomb Sqdn, and Lt. Michael R. Rebmann (23, Co-pilot)343rd Bomb Sqdn. On 4 December 1957, a MacDill Air Force Base B-47 exploded in mid-air over Choctawhatchee Bay, Okaloosa County, Florida. But modifications to a large fleet (especially structural modifications) As the landing gear arrangement made rotation impossible, it was designed so that the aircraft rested on the ground at the proper angle for takeoff. Fittings for nine such units were built into each side of the rear fuselage, arranged in three rows of three bottles. Lloyd, Alwyn T. "Boeing's B-47 Stratojet". The co-pilot reported that the MiG-19 jammed his MD-4 FCS (that aimed the tail guns), rendering it defenseless. The Soviets filed an angry complaint with the US government, which attributed the overflights to "navigational difficulties". Its final destination was Chanute AFB where it was used as a maintenance and familiarization aircraft. In actuality, a wheel door had broken away and prevented the control surfaces being fully active. Its top speed and combat radius superiority to the Soviet fighter jets were the deciding factors. Operational practice for B-47 bomber operations during this time went from high altitude bombing to low altitude strike, which was judged more likely to penetrate Soviet defenses. Six Allison J35-2 turbojet engines slung in pods beneath the swept-back wings gave the prototype Stratojet nimble performance, and helped to validate a design concept still widely used today. Peacock, Lindsay. Every large jet aircraft today is a descendant of the B-47. With a maximum gross weight
On 22 November 1958, a B-47B crashed while taking off from Loring Air Force Base in Maine, killing all four crew members on board. , Pleased with the refined Model 450 design, in April 1946, the USAAF ordered two prototypes, to be designated "XB-47". The total bombload capacity was to be 10,000 lb (4.5 metric tons).  One exploded over southeast Tulsa, Oklahoma, killing one crewman and raining debris over at least 8 square miles, witnessed by thousands of people on the ground. , Other interceptions resulted in losses. One of these set a course speed record of 601.187 miles per hour (522.417 kn; 967.517 km/h). , During the late 1940s, the bomber was hailed as the fastest of its class in the world. , Analysis work by Boeing engineer Vic Ganzer suggested an optimum sweepback angle of about 35 degrees.

Bill Gunston, a leading aviation writer, has observed that the B-47 was “design so advanced technically as to appear genuinely futuristic.” In addition to its high speed and sleek configuration, the B-47 was highly automated. The configuration of the B-47As was close to that of the initial XB-47 prototypes. , Starting in 1950, several models of the B-47 included a fuel tank inerting system, in which dry ice was sublimed into carbon dioxide vapor while the fuel pumps operated or while the in-flight refueling system was in use. Two cars were crushed, killing two occupants and injuring a third. Some B-47's were modified Once deployed, modifications were numerous. As was the practice at the time, the B-47 was carrying a single 7,600 lb (3,400 kg) Mark 15 nuclear bomb without its core.  "Reflex" missions proved the long-endurance (eighteen hours) and long range capability of the B-47 and aircrews. For greater comfort, both heaters and refrigeration systems were present in the cockpit to manage the cockpit environment. Three of the four crew and two civilians on the ground were killed. Wolfe, in charge of bomber production, for a ride on the XB-47. It handled well in flight, the controls having a fighter-like light touch. During this exercise, the F-86 collided with the B-47. The last RB-47H was retired on 29 December 1967. Three B-47E aircraft flew to Australia for demonstration purposes, but RAAF declined the B-47E as technically outdated and too resource-intensive. The aircraft hit the ground at an angle of 50 degrees. These last examples were given the new designation of RB-47K. The B-58, planned as a replacement for the B-47, started Upon retirement, XB-47 (46-066) was restored and placed on display at the Octave Chanute Aerospace Museum in Rantoul, Illinois, remaining there until the museum announced its closure due to financial difficulties in April 2015. of 116 feet. The majority of B-47 scenes were filmed at MacDill AFB, Florida utilizing aircraft from the 306th Bombardment Wing. "Fifty years later: Jet crash memorial to be dedicated in Comfrey". It had veered about 30 miles east due to inclement weather. Shorty afterwards 31883 arrived, followed by 31940, 31963, 32138, 31966 and 31915. The last USAF operational aircraft, WB-47Es assigned to the Air Weather Service, were withdrawn from use in September 1969. Moreover, forward basing of strategic nuclear forces was becoming
 The next year, this concept evolved into a formal request-for-proposal to design a new bomber with a maximum speed of 550 mph (800 km/h), a cruise speed of 450 mph (725 km/h), a range of 3,500 mi (5,600 km) and a service ceiling of 45,000 ft (13,700 m). restricted by space limitations. The B-47 needed defensive armament only in the rear because no fighter was fast enough to attack from any other angle.
