The B-52 has a take-off weight of 22 1 ton and eight TF33-P-3/ 103 turbine engines, each with a thrust of 75.7 dry cattle, so it can carry 27 tons of bombs. In addition, the maximum range of the B-52 is16100km, and it can fly continuously for 22 hours. Because the ceiling can reach the stratosphere of the earth 16800 meters, it is nicknamed "stratosphere fortress".
The B-52 bomber is a long-range strategic bomber with eight engines. The B-52 bomber is used to replace the B-36 bomber for strategic bombing missions. 1948 put forward the design scheme, 1952 made the first flight of the first prototype, and 1955 started mass production and put into use. Eight models, such as B-52A, B, C, D, E, F, G and H, have been developed successively, and the production was stopped in 1962.
There are 76 B-52 aircraft in active service, which are still the main force of strategic bombing of the US Air Force. The US Air Force budget allows the B-52 to remain in service until 2050. This makes the service time as high as 90 years. One of the reasons why the United States is willing to let the B-52 continue to serve is that the B-52 is the only type of strategic bomber in the United States that can launch cruise missiles.
