B-58D/E

Last revised September 21, 2020



There have been persistent rumors that B-58D and E Hustler versions were planned, but there is no evidence that such designations were ever officially allocated by the USAF. In addition, even if there were such designations issued, it is not at all clear what kind of aircraft to which these designations refer.

Drawings of a Hustler variant powered by a pair of Pratt & Whitney J58 turbojets have been seen, but it is not certain if these represent either the B-58D or E. There was also some thought of a Hustler version powered by four Pratt & Whitney J75 turbojets and equipped with downward-folding wingtips. The B-58 proposal with four Pratt & Whitney J75 engines and downward-folding is actually the B-58MI (Model Improvement) project. Again, it is uncertain if this aircraft is the B-58D or E, or perhaps some other paper project. Anyone out there have more information?
