As the advent of jet aircraft began to emerge in the late 1940s and early 1950s, Convair started design on a swept-winged version of the B-36 with all-jet propulsion. It also designed and built a prototype large-scale transport plane, the Convair XC-99.

The B-36G and the YB-60

In March 1951, the US Air Force authorized Convair to convert two B-36Fs to B-36Gs.

Since the jet aircraft was so different from production B-36 models, the designation was later changed to YB-60.

The eight-engine YB-60 shared 72% of its parts with the B-36. The fuselages of the two aircraft were nearly identical, although the YB-60 had a longer, pointed nose with a needle-like instrument probe, instead of the B-36's rounded nose.

The wingspan of the plane was 206 feet, the length 171 feet.

One YB-60 prototype was completed, S/N 49-2676, and used in test flights, with its maiden flight on April 18, 1952; a second prototype plane, S/N 49-2684) was never completed.

The YB-60's competitor was the Boeing B-52 Stratofortress, which the Air Force selected as its next generation of heavy bomber.

The B-52 could fly about 100 mph faster than the B-60. The two YB-60 planes were scrapped in July, 1954.
