Convair B-58A serial number 55-665 was unique due to the extended nose radome. This was in support of the YF-12 program: the AN/ASG-18 radar from the YF-12 was grafted onto the nose of the B58, and a special pod was constructed that would carry a single AIM-47 missile on a deployable “trapeze” launch rail like the YF-12.
SN 55-665 is one of the few surviving examples of the B-58. Sadly… “surviving” is a relative term. It’s sitting in the Mojave desert at Edwards Air Force Base, out in the approximate middle of nowhere; it has been stripped of pretty much everything including not only engines but also nacelles. It was placed there not as a gunnery target, but a photo target for satellite reconnaissance systems. (satellite imagery can be seen HERE) The desert is a benign environment for long term storage of metallic aircraft, but it it still non-optimum. It can clearly be found and climbed upon, which seems not only disrespectful but also unwise.
Seems to me that this aircraft should be taken to a museum and restored. However, restoring it to the appearance of a flyable aircraft would seem a virtual economic impossibility given its depleted state. Still… it does seem that it could be cleaned up, some missing bits restored, and put on display as a “cutaway” showing the inner workings of the aircraft.
