What is yb 60?

YB-60 is a prototype jet-powered strategic bomber that was developed by the United States Air Force (USAF) in the late 1950s. It was a modification of the B-52 bomber, featuring a tailless design with six engines mounted in pairs on the wings. The YB-60 was designed to replace the B-52, and was supposed to be faster, more maneuverable, and have a longer range than its predecessor.

However, after a series of test flights, it was found that the YB-60 was less stable and less fuel-efficient than the B-52. The USAF ultimately chose to continue with development of the B-52, which became one of the most successful bombers in history, while the YB-60 prototype was retired and eventually scrapped.

The YB-60 was an interesting historical artifact that represented a bold attempt to modernize the USAF's strategic bombing capability during the early Cold War period. However, it ultimately proved to be less viable than the existing B-52 design, and its failure helped shape the direction of military aviation development for decades to come.
