What is the max speed of the ARRW? I have seen many articles claim that it can reach Mach 20, really? I doubt it.
The ARRW, now assigned the designation AGM-183A, evolves from the Tactical Boost Glide (TBG) programme launched in 2014 by the Defense Advanced Research Projects Agency (DARPA). By using a rocket to boost the missile to very high altitudes, the unpowered ARRW then glides down to lower altitudes at speeds up to Mach 20.

I don't know why you doubt it unless you have actual hard information from the program that claims otherwise. Multiple publications have referenced Mach 20 for the TBG/ARRW and this sounds about right for the type of weapon it is envisioned. Lockheed and DARPA have had nearly a decade post HTV-2 to work to solve some of the challenges associated with such type of weapons and incorporate lessons learned and other improvements since then.

Lockheed Martin claims both USAF hypersonic programmes
The US Air Force has selected Lockheed Martin to rapidly develop and field both new hypersonic missiles launched as a response to surprise developments in high-speed weapons by China and Russia, newly-released acquisition documents confirm.www.flightglobal.com
The first weapon, the AGM-183A Advanced Rapid Response Weapon (ARRW, pronounced “Arrow”) is an outgrowth of the DARPA’s Tactical Boost Glide program. ARRW is a rocket carried aloft by an aircraft such as a B-52 bomber and has a top speed of up to Mach 20.
I don't think that size of whole design can reach Mach 20....
Let’s hope nuclear and conventional
Why would you think it could?I don't think that size of whole design can reach Mach 20....
In June 2018, the Air Force announced it was looking to purchase new pylons for the B-52 to carry multiple, unspecified 20,000-pound class weapons.
I have a feeling it is the whole thing having read about ArcLight. If a 6.5m long 533mm missile can deliver a 90kg warhead 2,000nm, then the same missile increased to 800mm diameter can probably carry a 200kg warhead the same distance and if you can carry a dozen of them, that helps target saturation.Maybe that thing that was shown on the B-52 is only the upper stage of the missile.
Incorporating only the upper stage would make absolutely no sense for a carry test. Not having part of the missile body attached would completely invalidate any aerodynamic or vibroacoutic data collected during the flight. Also, why would the suspension lugs be on the upper stage?

Why fly a Pershing II like this:

Point being, if the weapon does include a booster stage, not doing the aerodynamic testing with the booster stage is useless. Worse, actually, because it wastes time and resources testing a configuration that would have no relevance to the operational weapon. So this is clearly the whole weapon and there will not be a booster, at least not initially.
I think what was suggested is that what is shown might be one complete weapon and the same thing with a booster might be another complete weapon. Sort of like a Derby and Derby-MR. But that's a complete guess, the 20,000lb weapon might just be a completely different weapon.Point being, if the weapon does include a booster stage, not doing the aerodynamic testing with the booster stage is useless.

Oh, OK, I see that. I suspect it's not likely, since the speed regimes for the two notional configurations would be really different, implying different payload vehicles. The 20,000-pound weapon is probably something else entirely.
