Didn't a US test recently achieve Mach 15 or over? And one of the programs aims for >Mach 20 top speeds.

Doesn't AGM-183 fall under the ARRW program umbrella?

I'm not aware of anything recent in the US flying Mach 15. Maybe they tested one of the missiles designed to be used by the USN and US Army? (Boost glider based on the ancient SWERVE test vehicle. More a maneuvering RV than a true glider though.)

AGM-183 and ARRW are the same vehicle. Apparently the documentation is a bit deceptive. There is money allocated for one more test and money for follow on development allocated somewhere else.

"This is not the correct take (I've pointed it out to Steve in comments below the tweet). The RDT&E or prototyping funding for ARRW is going away in FY-23 because it is expected to end the development and prototyping phase of the program. This would have happened in FY-22 had there been no delays. The AF has opened up an ARRRW line in its procurement budget. This currently includes $40 MM funding for tooling and AUR production but that is apparently being diverted to cover the shortfalls on the testing side to make up for the delays. However, if the program is successful over the next 12 months, the AF can request reprogramming, and the Congress can add dollars into this procurement account to avoid a gap between FY-23 RDT&E completion, and additional FY-24 funding.

All in, the AF has build a mechanism to finish ARRW development and testing, and to begin buying the missile once it is ready. Whether they do this, and at what pace, will be highly dependent on how the program is executed by the armament directorate and Lockheed Martin."


I recall the US expressing doubt in how effective hypersonic weapons are due to exorbitant costs. They haven't planned on cancelling projects due to costs but it's an interesting comment on this class of weapons. Seemingly suggesting they haven't worked out how to control the costs from getting crazy and making the weapon essentially near useless except as a doomsday nuclear delivery system which I recall being something one of the articles claimed is how they expect China to operate hypersonics - as nuclear delivery only because it is simply too expensive to use conventionally.

There is also the time to target aspect. If a target of opportunity is spotted that needs to be taken out ASAP a high speed weapon might be the only way to hit it before it moves again. Hypersonics (and good C3/I) is the best way to do that. I'd wondered about the Russian use of Kinzhal and Bastion in Ukraine. Maybe they were fleeting targets.

I'd argue it's because these weapons are not exactly anywhere near as useful to the US as it is to China. A result of the military postures and doctrine of the two with China being in a defensive position and requiring A2AD, also making expensive forms of A2AD worthwhile. Meanwhile the US wants power projection and hypersonics aren't exactly any more effective than any other PGM. Their aim is control of air and sea so that airborne assets can use PGMs - considerably cheaper and easier to make than hypersonics. However it's very difficult to use a PGM to sink a carrier and even a hypersonic at 10x the cost or 100x the cost of a PGM is well worth it if it is able to perform this role.

So their "lack of trying" is more down to these reasons.

It's not lack of trying. It's lack of commitment. Too often the US quits at the first sign of difficulty. But yeah, there hasn't really been a pressing need, I'll give you that.

And come on, yeah US funding isn't infinite but it is as close to being effectively unlimited as any other. Over 4% of GDP (the largest GDP sum mind you) compared to China's not even 2% GDP spent on military. Okay lots of bases to maintain and higher pay for pretty much everyone. That's still at least similar available funding. It's just they don't see anywhere near as much value as China does and this is down to the military posture of the two.

I'd argue the US, effectively, has a smaller budget than China all things considered. Everything on the list costs less in China.

On the same topic, looks like USN has now put it's foot down on hypersonic cruise missile.

We will see if they actually field it by then.

I should add that LR SAM for F-35 doesn't mean engaging it at the extent of its range but basically being able to carry more energy to improve its interception probability at far closer ranges. Let's say tracking and launching missile at F-35 can be done at range 100km, this would give a 200km ranged missile a lot of energy at 100km away from launch site. F-35s have stand off weapons of range well beyond 100km though so of course the only hope of engaging F-35s would be at longer ranges otherwise at least these missiles can be used in defence of ships against anti-ship missiles. All assumes detection tracking and fire control are all working effectively at range.
If China can consistently lock onto and fire missiles at F-35 from even 70 km out with J-20, US military would completely freak out. Keep in mind that there is nothing particularly special about LR ASM or F-35 carrying them. Of all the ways that F-35s can threaten PLA, carrying JASSM or LRASM externally to attack Chinese surface ships are not high up on that list. In fact, it wouldn't be more threatening (in y mind) than the bug doing the same thing. Sure, they will be harder to track than harpoon or SM-2, but with multiple aerial and surface combatant datelined together, they should be able to pick a lot of them up at the same time.

A future Chinese carrier group will need to be able to track hundreds of missiles of intercepting them. Keep in mind that a USN carrier group can track of thousands of targets and handle hundreds of anti-ship missiles.
The only counter PLAN has against this are the dedicated A2AD weapons mentioned and maybe subsurface capabilities. Surface ships can extend the range of A2AD and are all sensor nodes but they lack the range to directly engage USN carrier groups because aircraft outrange PLAN surface ships' "conventional" anti ship weapons coordinated wave attacks. Throwing handfuls of YJ-18s cannot be assumed to do much except expend USN interceptors.

Actually, aside from their recent development, YJ-18s are just about the most ideal anti-ship missiles you can find. They combine the long range and low profiles of subsonic missiles with terminal high supersonic missiles.

Now, I think your concern is that PLAN will be going against USN carrier group alone. That seems to be a premise. In fact, I don't see any scenario where PLAN would risk exposing its surface combatants to US air power without any kind of air cover. That would be a really stupid thing to do. Even for shipborne ASBM, they still need aerial assets to help them find US carrier group and target correctly.
Therefore the long term deterrence to achieve is force parity because there are always going to be counters to latest weapons no matter how impressive they are when they are new. A peer force in conjunction with world leading A2AD is going to be ideal and enough for a Taiwan scenario. Only one of those may not be enough to discourage US involvement in any Taiwan scenario. Right now China only has the A2AD side and building up the conventional force.

We have seen several major development in Chinese anti-ship missile programs in the past 15 years:
1) the proliferation of long range high subsonic missiles like YJ-83s and YJ-62s. As impressive as it was (like 8 YJ-83s per Type 022), that didn't really trouble or scare USN. USN faced much stronger threat in the Cold War.
2) the proliferation of long range high supersonic missiles like YJ-12 and YJ-18 on both bombers and surface warships. This is actually much more dynamic threat, since you could have Type 055s launch a whole bunch of sea-skimming supersonic missile at something like AB. Since I haven't been following things for 5 years, I can't tell you if USN freaked out over this. I would think they have not since the threat level here is no higher than Cold War days (missiles have gotten better but so have surface warship AAWs)

3) the likely proliferation of air and sea launched ASBM and hypersonic anti-ship missiles. I remember the alarm that went up when ASBM news first came out (in fact, it was my entry on informationdessimation which got subsequently posted on the Drudge Report and USNI) that caused very high alarms. I am waiting over the next few month to see if we get the same type of alarming article from US military that we saw when the HGV FOB tests were conducted. I think we will. That could spur a huge push from USN to devote addition funding for interceptors and radar system to defend this. I think this will push USN carrier groups to be further out.

Yeah, that's where the US is cripplingly behind. "Risk" is a 4-letter word that strikes terror into anybody near the pursestrings in the US. That's how you get three failures on HyFly and then they quit without ever seeing if the damn thing actually works. Same is happening to ARRW. It's had three failure, none of which has even got to the booster firing, and now they've zeroed out the funding for it. I think it gets one more attempt but then, regardless of outcome, there is no money. Compare SpaceX 's Starship to NASA's SLS. Same thing.

I don't think US military had the same impetus as PLA to push HGV/HCM development. USN carrier group would be able to overwhelm any defense with air launched AShMs and a barrage of SM-2. It's only in the past 5 years that PLAN is building a robust enough surface combatant fleet that might theoretically be able to defend against saturation attack from USN carrier groups. Are there any other navies capable of defending against saturation attack of hundreds of missiles? PLA pushed for hypersonic missile development because USN is capable of dealing with saturation attacks.

I think what you have pointed to is a real problem with US military, but it's not the only high level problem. Fundamentally, US military believes that it needs to be able to dictate warfare anywhere around the world with much less loses than its adversaries. While that worked when everyone was spending less than 1/10 of DOD's budget, that doesn't work well when China is at 1/3 of US' military budget with significantly lower development and production cost. I mean the Chinese costs is many folds lower. When you pursue this high threshold level, you are driven to pursue capabilities that your adversary don't need to pursue. For example, USN will likely be devoting an obscene amount of money to protect its carriers against the ever improving PLAN hypersonic AShM. PLAN likely will not be chasing similar type of capabilities.

I'd argue the US, effectively, has a smaller budget than China all things considered. Everything on the list costs less in China.
Yes. And anyone that has the recent inflationary pressure in America knows how much things cost here.

What evidence do you have that this is anything but fantasy?

LRASM probably has the lowest RCS of anything flying, an intelligent passive guidance system, 450kg warhead, and a 500km+ range. So the stealthiest cruise missile on the planet being fired by a stealth aircraft is "nothing particularly special" huh? :rolleyes:

Except your little missile is ponderously slow lol. Little value to low RCS after it's crested the horizon, not like it wouldn't be immediately detected in any case. Crawling at turtle speed even in terminal phase, easy to destroy with short range and point defences. Will be even more of a joke once laser CIWS are fielded.

What I'm more curious about is whether the LRSO would have a chance of penetrating mainland airspace especially to attack silos, seems that is its main mission anyway without a conventional warhead option.

I'm confused here. Are you saying it's a fantasy that USAF would freak out or that China can consistently lock onto and launch missiles at F-35 from 70 km out?

What I said may not be too clear, but I was responding to the idea that "tracking and launching missile at F-35 can be done at range 100km". Simply saying that even if this can be done at 70 km, it would be quite the unexpected scenario and cause freakout in US military establishment.

In the context of F-35 launching it? Having F-35 carrying weapons externally can only hurt its stealth profile. Making it more easily trackable. A bug carrying 2 LRASM and launching them from standoff range would be just as lethal. LRASMs launched from warship would be similarly lo profile. I don't see why F-35 launching it makes things more difficult than a saturation attack from other platforms.

As for LRASM itself, it wouldn't be different than tracking any other sea skimmers. You still rely on network of sensors both in the air and surface combatants, CEC, advanced datalinking and such. Maybe you can't deal with as many of them coming at you at the same time as you would with SM-2/6s, but they are still subsonic missiles flying sea skimming profiles that wouldn't be that difficult to intercept once you are able to track it.

Yes, they would be upset. There's nothing to suggest it's reality. Or even close to reality.

It's a matter of degrees. It would still be WELL outside trackable range at launch.

Wouldn't be different except for that whole stealth thing. That makes it a LOT different. It's also got a lot of ESM equipment onboard. That's what enables it to actively react to threats to it. It doesn't just blindly run out with an active radar seeker broadcasting it's position.

I'm sure it does. But you also seem to be unaware of China's counter stealth development in the past 20 years. I will leave it as that.

Have somebody explain to you what "stealth" and "reaction time" mean.

You can't hit what you can't see. I'll bet you think a hypersonic weapon will be more survivable against a laser. :p

I'm aware of the claims. Still wiating for Russian "plasma stealth" when it comes to claims. The fact that China's newest fighters incorporate stealth (and you can be sure their new bomber will as well) demonstrates even the Chinese agree with its utility.

Stealth just means reduction of radar range not invisibility, a stealth missile popping out of horizon at a range of 40 km will get spotted by modern warship, the distance is so close that raw radar power burn through whatever stealth. After that it is a long 120 seconds of subsonic flight (crawl) to reach it's target, good luck with that

A better indicator would be whether PLAN/PLAAF jump on the stealth missile bandwagon and procure their own LRASM, so far it looks like they favor the Bruce Lee philosophy (speed) and not the ninja philosophy (stealth)
