Humans have never paid as much attention to the role of long-range bombers as during World War II. In the European battlefield and the Pacific battlefield, advanced long-range bombers attacked thousands of miles and dropped deadly aerial bombs to accelerate the victory of the war. In the 1940s and 1950s, many popular products emerged, including the B-52 "Stratofortress" bomber.
B-52 has been synonymous with long-range bombers for a long time. The B-52 was established in 1948, achieved its first flight in 1952, and was delivered to use in 1955. The development process was smooth. Many people suspect that the B-52 has been in service until now, with a long history of nearly 70 years, and it is likely to have the support of German World War II black technology.
B-52 can be regarded as a milestone in human bomber technology after the end of World War II.
In November 1945, the soldiers who had just won the Pacific War were not immersed in the joy of victory. The desire for an intercontinental range bomber gave birth to a "crazy" research and development plan. This imaginary bomber will have a combat radius of 5,000 miles, equivalent to 8,050 kilometers. Even from the current perspective, this is extremely difficult to achieve.
Finally, Boeing's Model 462 program won the tender and later became the XB-52 test machine, which was the predecessor of the B-52. After a series of experiments and adjustments, the B-52 was officially approved in 1951 and began to be delivered the following year.
The body of the B-52 has a slim and straight cylindrical shape. This design is easy to manufacture and helps reduce errors. Its power source is 8 sets of YJ57-P-3 engines built by Pratt & Whitney. They are divided into four groups and installed in a special engine nacelle, which plays an important role in stabilizing the center of gravity of the wing profile. Even if the vertical tail is severely damaged, the B-52 still has a chance to return safely.
B-52 can be equipped with Mk28, Mk39, Mk43, Mk53 and other big killers, and it can also be equipped with AGM-28 "Beagle" cruise missile. Its maximum take-off weight can reach 220 tons, and its speed can reach Mach 0.81, which is equivalent to 1000. Kilometers per hour,It is worth mentioning that the B-52 ultimately failed to achieve the goal of a combat radius of 8,050 kilometers, but 7,210 kilometers.
B-52 later developed eight different models of improved models, the latest model is B-52H, a series of advanced technologies are added to B-52H, let it glow with youthful vitality belonging to the 21st century . To date, there are still 76 B-52 bombers in service, and perhaps they can remain in service until 2050.
