Apparently this program is being rapidly prototyped. The initial test shape has flown on a B-52 to test vibration and areodynamic characteristics, with IOC rather optimistically stated as being 2022.

Since there is no information concerning the system that I can find outside the basic fact it is a boost/glide type hypersonic, I wanted to open the floor to wild speculation. Predecessors? Guidance? Target set? In regards to the former, it seems like a very wide body missile. The B-52 carrying it looks to have had its port heavy stores beam modified with two unique hard points to carry the weapon, with only one carry point occupied. That seems to point to weight/clearance/separation issues that would limit it four weapons in an operational configuration. The missile itself is very wide and I suspect is not a custom build - the Russians and later Israelis rapidly introduced high speed weapons by co-opting high speed ground based artillery. But the US has no such weapons. Available pictures of the test object look faintly like they might be based on GBM or Minotaur I/II family, themselves derived from Minuteman III. In this case I'd venture the second stage motor - thoughts?

So I guess we don't know if it can attack only ground targets or also sea targets? Maybe optional low field nuke version is possible down the road?

Why not go back to the AGM-28 Hound Dog missile envelope//pylon?  10K lbs weight, 40ft length.  S/F....Ken M

I think sea targets would be a much lower priority, especially for the USAF. Even the USN wasn't especially concerned with anti-surface until recently. Plus I think terminal guidance against moving targets will be *far* more challenging than hitting static targets which could just involve GPS/INS guidance. I don't see any reason why nukes would be useful unless you share the Russians' paranoia concerning ABM defenses.

The goal is a conventional weapon with precision and extreme speed and altitude. Hound Dog doesn't fulfill that requirement.

^ I mean that size frame, not the exact missile.  Less legitimate qualification stuff, as well as reduced bullshit pogue paperwork and opportunity for waste fraud and abuse.  S/F....Ken M

I don't see what that would buy you - if its a different missile using a different motor, you'd still have different CoG and such. It would still be completely different certifications, captive carries, etc. I suspect the project does use a current missile as its basis to save time and design work, but I think it is something much more modern and solid fueled that hasn't previously been air launched.

They keep trying, and so far they only wasted money.

Hanging things on airplanes is more difficult than you seem to think.

USAF has an entire program (Seek Eagle) to insure that munitions separate cleanly from the aircraft without causing damage. There's various YouTube videos that show munitions porpoising back in the airstream and impacting the aircraft.

You know you're an aircraft nerd when you hear 'separation issues', and instead of thinking of your child or last girlfriend, you ponder if the next B-61 mod 12 will work out:
