Lockheed Martin AGM-183 Air-Launched Rapid Response Weapon (ARRW)

I thought ARRW was a reworked HTV-2. That was flown twice. It terminated early in both but had enough data to confirm the aerodynamics/flight control seemed to work. I believe it was the thermal protection on the 2nd flight that caused problems.

No way. That thing was launched with a Peacekeeper ICBM (essentially).

If you read the April 2020 issue of Air Force magazine, there is an article starting on page 28 covering the various hypersonic projects. At the bottom of page 29 it says (paraphrasing):

The DARPA program, called Tactical Boost Glide was to serve as the basis for ARRW

The appearance of the ARRW and HTV-2 are pretty similar. I can believe the HTV-2 was bigger and needed a large booster but a scaled down version might still be the design base for ARRW.

I think some graphic designer took liberties with the copy/paste. A glider as small as that in the second picture doesn't have enough volume to hold much of anything.
 
Is there a warhead on this or is it pure kinematics to destroy the target?
 
It is undoubtedly the more advanced design with greater capability. Just hoping the flight testing goes well. Worst case, presumably HCSW could be dusted off next year if major problems arise. The glider is supposed to be from DARPA TBG - has that ever been flight tested?

No it hasn't been flight tested, but the ARRW program will follow after TBG has been flight tested which should happen sometime in the short term. TBG also has a second vendor allowing the USAF to re-evaluate at a later date in terms of which BGV the prefer for the long term. So basically by keeping TBG and ARRW alive (USAF has funding for TBG as well as it was a joint USAF-DARPA effort) they are bringing three BGV's through flight demonstrations (C-HGV, TBG-LM, TBG-RTX). That is a better ROI for USAF and broader DOD R&D dollars than going all in on just one. At the end of the day they have to establish an acquisition program for the ARRW and then build some sort of acquisition program that right sizes the buy to make all this affordable.

Wouldn't matter. The booster is only 30" dia. Makes the glider what. . .5" thick, maybe?
 
If there is a warhead, I think it would only be a bursting charge to fragment the glider for soft targets. The diameter as noted above is ~31 inches/80cm; there couldn't be room for much more than a guidance, power source, and control surfaces.

Er, Tomahawk is 52 cm in diameter and carry 450-kg wahread.

The Tomahawk is also a one piece weapon basically with a small booster.

The AGM183 is mostly booster with a small missile part. That black arrow head on the end of the weapon.

That is the AGM183 kill vehicle, that is the part that flys off to do the work and ONLY THAT. The rest of it is basically a booster to get up to speed and attitude. Think more Saturn 5 set up, BIG OLD ROCKET, with an itty bitty tiny command and life support module. That little arrow head has all the eletrics, batteries, fuel, and the warhead to hit the target with.
 
More over, not only is the terminal glider not very wide, the shaping of the projectile means it will be waffer thin. The conical glider the USN is developing will have much more room, but will be less aerodynamically efficient.
 
Any warhead or kill capability will be based on the ARRWs target set which would have been defined by the USAF quite early on (when they put the T in TBG). That would also impact guidance and other trades.

Then again the size of guidance systems have shunk a lot in the last ten hears.

It is now possible to make a quad mode seeker the size of a cellphone these days, looking at the GDU53s. Hell the Army has a tiny GPS guidance kit in the PGK. And batteries have come an extremely long way too.

Either way, it will not surprise me if the Arrw has a sizeable warhead thanks to the guidance being tiny.
 
Is there a speculated range and impact velocity for the warhead? My google-fu hasn't really found much. Did see one article speculating on 2,000km range but that seems high to me. I've read Mach 20 as well but I'm not convinced that's it impact velocity.

Mach 20 has nothing to do with this vehicle, anywhere in it's flight profile, at impact or no.

A 1,000 km range has been attributed to the ARRW by the defense media and later used in a bunch of CRS reports. Not sure whether any official USAF publication has cited it but that is what we have to go by for now.
 
No stats are published, and since it is a glide weapon 'speed' and 'range' are very relative things...once the glider is released, you trade one for the other.
 
One would think that the 1,000 km number came to the media via the AF or Lockheed and if so would likely represent some sort of realistic range of the weapon given its intended use case. I think it was first reported by Steve Trimble. Even then, I don't think you'd want to spend a Billion dollars developing the weapon, and then a considerable amount trying to create an industrial base to produce them, just to launch them as if you were launching a ballistic missile. These would be reserved for, at least initially, the harder to reach targets, or those that are extremely time-critical.

Thank you I just say WOAW !! Do you think it will fit inside the B-21 bay ?

ARRW's range: "handfuls of hundreds of miles"?

"...DOD describes its hypersonics programs with terms like “medium” or “long” range. What does that mean?

“We’re very cautious about attaching numbers to exactly what we mean,” Lewis said in an interview. “All these systems wind up flying really long distances.”

For medium range, though, he said, “we’re talking about handfuls of hundreds of miles. Long range, we’re talking … a couple thousand nautical miles. It’s intentionally fuzzy.” The Pentagon, he said, is “still figuring out the concepts. That’s part of what we’re going to be exploring with our upcoming flight tests.”..."

Is it just me or ARRW diameter look very small? barely thicker than JASSM

Jassm is 550mm wide, Arrw is 750mm.
The shot makes you see the entire breadth of jassm while arrw full aspect diameter is not visible.
 
The missiles have different paint schemes. Is one instrumented and one just a dummy round?

"For the test, the B-52 was loaded with two representative ARRW Instrumented Measurement Vehicles (IMVs) carried in tandem under the port wing pylon. The forward missile of the pair was the principal trials subject, known as IMV-2. After flying a series of orbits to the north of Edwards, the B-52 transited to the Point Mugu Sea Range, south of the Channel Islands off the coast of southern California. From there IMV-2 transmitted positional and telemetry data to the range’s ground stations."

Yes, IMV-1 was the aft store and was unpowered.
