I know. Its strange. But that is what the USN mentioned in work its previously funded to Castelion. We could be looking at a surface launched version with a booster and an air launched system without one so that's also something to consider.

Air-Launched Blackbeard likely won't have the booster.
That or they're planning on developing a smaller booster for the Navy version...

Here Is What Trump's Gargantuan $1.5T Defense Budget Has In It

The U.S. military is pushing to make huge investments in many programs in Fiscal Year 2027, but also some notable cuts.

(Sry for going off on a tangent)...I'm still puzzled how guidance works on a hypersonic missile? Not only the nose shape on scramjet missiles, but the problem of plasma. USN wants anti ship scramjet missile. Which means targeting moving ships. Don't they have to slow down to below mach 5 in terminal phase of the attack?

I doubt that plasma is an issue at ~Mach 5. A lot of AAMs and SAMs enter that speed range, although usually only briefly at their max velocity. A high altitude missile might simply mount it’s terminal sensor in a ventral, look down position - on something like HACM I would think the compression ramp between the tip and the intake would be a relatively cool piece of the airframe (compared to the nose or control surfaces) where you might locate a sensor. Alternatively, have some kind of cover that ejects in the terminal dive to the target. Pretty much every hypersonic becomes supersonic in the dive through the thicker lower atmosphere.

This has been figured out...
The US has weapons that reach well into the Hypersonic realm.
THAAD 's max speed can reach something like Mach 9+, as it's sensor's guide itself into the incoming missile. The SM-3(IIA), I've read can go over Mach 12, so..!

I would suspect that those kinds of speeds are attained at altitudes high enough that there enough atmosphere to create a strong plasma shell. The SM-3 is entirely exoatmospheric, so it doesn't even try to deal with plasma. In BMD terms, plasma is probably only a significant problem for low-altitude, high-speed interceptors like SPRINT, which was externally controlled.

They're both IR seekers. They're not trying to get RF through plasma. (Which you'd have to do if you were using a radar seeker.) Pershing II used a radar DSMAC but I seem to recall reading something like "it's eyes didn't open" until it got below certain speed.
