Hypersonic Surface-To-Air Missile (HYSAM)

I cannot say I've seen this one. Hypersonic SAM?

Very highly-swept wings and tailplanes on what I guess is your generic ogive forebody, possibly an elliptical one or flattened on the bottom half. Aft end of a hollow box-like structure can be seen under the tail which then seems to ramp up on the bottom, suggesting an expansion ramp.

Apologies for the hipsters in the second photo. The parallelogram object appears to be an engine cowl, and the nose ogive is definitely flattened a bit on the bottom leading into the cowl. The tail expansion ramp can be seen in clear profile.

seems that this was one of many HYSAM variations studied (more on these in the evening)

Interesting approach with the compression ramp. First thin sidewalls, then the ramp closing in vertically. I guess this simplifies design greatly.

A variation of a 3-D "sidewall" compression inlet, ala the NASA Langley 3-Strut inlet without the struts.
