KB-50J on display at the Pima Air And Space Museum. The Pima museum is across the road from the famous US Air Force boneyard at Davis Monthan AFB. As a result, the Pima museum has a huge collection of retired military aircraft, especially those from the Air Force.

This photo shows the large air intakes under the engines, something that the B-29 did not have. The nose glass also differs, with a single flat piece of glass for the bomb sight, and a second single piece of glass for the rest of the nose. Something that is not as easy to see in this photo are the two additional jet engines mounted under the wings. These jets provided additional speed to help the KB-50J keep up with the early jet bombers such as the B-47. Even with the jet engines, the KB-50J was not up to the task of refueling a B-47, which lead the USAF to go after an all-jet tanker as quickly as they could.
