Interesting ROK report on hypersonics here, includes some interesting references, including a UK blended body research project of DSTL UK.
Why is common hypersonic glide body warhead using a double conical design with 4 large fins, which is a symmetrical design.
And the agm183 arrw warhead uses a flat body assymetrical design with two wingtips and no fins?
What are the advatanges and disadvantages of each design?
Also warhead/packing volume. I remember seeing the brochure for ARRW and it has a pretty small warhead. View: https://twitter.com/masao_dahlgren/status/1164990693518929920?Why is common hypersonic glide body warhead using a double conical design with 4 large fins, which is a symmetrical design.

The biconical glide body is less efficient (more drag) because it has to maintain a higher angle of attack to generate lift. It is apparently easier to construct (or possibly model) and was designed in 80’s as part of the DARPA SWERVE project. It was a lower risk glider that could be rushed into service. The USAF equivalent was to be HCSW. The other glider was from the much more recent DARPA Tactical Boost Glide program and has superior performance, but was less mature technically. Congress forced the USAF to consolidate to a single hypersonic glider weapon program and they went for the higher risk TBG based system which was apparently smaller and lighter weight, allowing more to carried (presumably HCSW was large enough only one could be carried per B52 HSAB). The USAF also has the HACM program long term, and it seems that the much lower weight/cost of scramjets is where USAF would rather be - enthusiam for AGM-183 seems lukewarm. The US Army and USN stuck with the biconic glider to reduce risk.
Most likely LRHW. JFC-2 and 3 need to take place soon.Possible IR-CPS test?
Mysterious Launch Out Of Cape Canaveral Appears Imminent (Updated)
All signs point to an imminent test launch of an exotic system, possibly of the hypersonic variety, from Cape Canaveral Space Force Station.www.thedrive.com

"Last weekend saw a scrubbed Hypersonic Missile test from Cape Canaveral, Florida (see a previous post). It looks that another Hypersonic Missile test is upcoming next week, this time in the Pacific in front of California. Lines of evidence point to this Pacific test being another test of the hypersonic AGM-183 ARRW."
"An odd Navigational Warning, NAVAREA IV 221/23 (text of warning below, areas mapped above), was published on March 1, suggesting a launch from Cape Canaveral with a time window from March 2 tot March 6. The jury is still out on what it is, although opinions are converging on a missile test, possibly a test of the hypersonic LHRW."
Safe to assume not very as little as they've said about it.But how successful was the test?
1. Broke away from the planeBut how successful was the test?

2 .....
3. Fell to the ground or into the water
two of the three items were completed successfully
Quitting isn't the way to figure this out. I can't believe this has to be said. Our government is pathetic.Isn't ARRW supposed to be the 'safe, simple, soon' option? If HACM is proceeding better anyways, might as well go all in with that.

Yep. These idiots seem to think if they cancel a program and wait ten years that next time there won't be any problems.Quitting isn't the way to figure this out. I can't believe this has to be said. Our government is pathetic.
The problem with hypersonic research in the US is the start-stop, start-stop, start-stop to programmes and funding, what they need is a long-term research programmes with consistent funding.
Hypersonic ship-killer: Navy taps Lockheed, Raytheon to start developing HALO missile - Breaking Defense
HALO is the follow-on program to the Long Range Anti-Ship Missile, produced by Lockheed and used on both Navy and Air Force warplanes.breakingdefense.com
In February, the 1st Multi-Domain Task Force (1st MDTF) long-range fires battalion, 5th Battalion, 3rd Field Artillery Regiment (5-3 LRFB), deployed the Long-Range Hypersonic Weapon (LRHW) system over 3,100 miles from Joint Base Lewis-McChord, Washington to Cape Canaveral, Florida during Thunderbolt Strike, a full rehearsal of expeditionary hypersonic launch capabilities.

More like 1990 - I've seen little evidence anybody over here has woken up. Mostly just revisiting well-worn paths.1990-2020 - The Hare takes a nap.
Well they're actively trying now, just reincarnated as a tortoise.More like 1990 - I've seen little evidence anybody over here has woken up. Mostly just revisiting well-worn paths.
Very confusing to reuse a very common and well-known name for an entirely different program.
