Developed by Boeing, the B-52 is a heavy bomber with an unlimited range thanks to aerial refueling. It can carry payloads weighing up to 20,000 pounds and an array of weapons to include cluster bombs, precision guided missiles, and nuclear weapons. The first B-52 flew in 1954 and the B model entered service in 1955.

Fin span reduced, ailerons deleted, nose radome enlarged. A Boeing B-52G made a record flight around the US, covering 9,000 non-refueled miles in 18 hours 30 minutes. I worked on the B-52G DFCS at Travis AFB from 1963 to 1966. Years later while working in the telecom I came across an old friend 58-0158 at Fairchild AFB while the 5th BW was there.
