On Kinzhals, Patriots, etc.

What can be intercepted with which means depends on quite a number of factors and their mutual effects: where the incoming missile is launched from, where its target is, where the "anti-missile" launcher is...

1/
...and, perhaps most importantly, where the defending side's radars are (detecting, targeting, etc.).

How coordinated the "incoming" and "outgoing" salvos are also very important.

2/
On Kinzhal as a "real hypersonic weapon" I hoped everything was decided back in 2018: speed above 5 Mach, maneuvering inside the atmosphere, a significant "non-ballistic" part of the trajectory - bingo, this is it. That said...

3/
...hypersonic does not equal invulnerability, but should, in general, increase the probability of overcoming air/missile defences and reduce the required salvo per target. The emphasis on air/missile defence penetration or accuracy for is highlighted based on political needs.

4/
What's also interesting is that "hypersonics" are believed to lose more velocity on a conventional trajectory than a classic ballistic missile, plus terminal guidance might require slowing down, so the velocity drops even more.

5/
Accordingly, this very terminal phase is where it is most vulnerable, especially if you know exactly where it's coming from. If it flies directly into a missile defense battery, theoretically the intercept could be more successful. That said, if it does a classic "gorka"...

6/
...and arrives steeply, in a notional scenario the attacker's chances increase, but in reality there should be layered air and missile defenses to cover each other.

7/
It is a questionable idea to hit an area soft target with a single unitary penetrator, as CNN tries to convince us - but we are already used to not being surprised by anything. Claiming mass intercepts of everything while there are videos of explosions is also strange.

8/
And, yes, don't forget that any sophisticated technology, and missiles certainly are, is prone to failure. In short, the fog of war hasn't really dissipated much.

Think with your heads.

9/
P.S. About Storm Shadow/SCALP-EG - first confused by the lack of intercepts, now confused by the overclaims. (not really)

There is little doubt that the flight missions in these rather advanced cruise missiles are being prepared, shall we say, not at the local level...

10/
...and those are operated according to, well, military science. At the same time RU Air Defence Forces were being prepared for exactly this kind of threat. All in all, we are learning in a real way.

In a bloody way.

Rather long interview with Vladimir Degtyar, head of Makeyev design bureau and basically liquid-fuel missiles tzar: rg.ru/2022/11/23/sil…

Sarmat in serial production (probably he means parts of it)

1/
Sarmat warheads have are GLONASS-assisted and covered in some sort of stealth coating that complicates their detection and trajectory calculation both in the atmosphere and in outer space

2/
Cooperation with VNIITF on payloads included "combining izdeliye bodies (aeroshells? warheads?), expanding the range of standard sizes, solving the problems of hypersonic flight"

Rather big and detailed interview with Yuri Borisov, current had of Roscosmos, about challenges and plans: tass.ru/interviews/163…

[In Russian, but will make a thread later]
Industrial approach to satellite-building planned to switch from current ~15 satellites per year to a satellite per day. Existing approach might give 40 per year though, but a change is needed to achieve modern mega-constellation capability. Expected around 2026...
Sphera project will be a major instrument: five orbital communication constellations and five new Earth remote sensing constellations based on smallsats. First stage with 127 spacecraft by 2026.

The more I see footage of Chinese TELs, the more I think their operational mode is very different from what we are used to in the Russian SRF.

1/
Russian best practices: off-road chassis, patrols deep in the woods, launch from unprepared positions, long caravans of guard, command and support vehicles. And Krona light shelters.

2/
Looks like PLARF focus is on motorways and probably the idea is to leave hardened shelters, tunnels, etc., launch, roll back (reload?..). Given their military and civilian construction and automobile production capabilities, there might be A LOT of decoy shelters and TELs.

Nice #hyperhype X lethal autonomy from Sandia circa 2019.

I've been arguing publicly that autonomy has some role for hypersonic weapons since around early 2019 as well:)

A thread on Zmeyevik, new RU hypersonic weapon reported by TASS earlier this week ().
Looks like it was under development for a while, although there were no tests mentioned or observed, which, does not mean that there were no tests at all.
1/
Making fast AShM is quite traditional for SU and RU school, and the ballistic missile is a good option (also, R-27K SLASBM). Still, given its range and speed one needs a serious ISR and targeting capabilities, and also terminal guidance.

2/
Maneuverable reentry vehicles (MaRV) and hypersonic glide vehicles (HGV) as a subtype of those make sense to be a primary payload type in this case, however there are obvious gaps in Russian ISR capabilities anyway.

New name for the Russian hypersonic weapons geeks: Zmeyevik. According to TASS sources, an anti-ship ballistic missile with HGV payload for the Navy coastal missile units, to strike large surface targets, somewhat like DF-21D or DF-26.

tass.ru/armiya-i-opk/1…

#hyperhype
Sources claim that the project has been under development for a while already.

"Zmeyevik" is a kind of serpentinite rock, as usual. But also this thing often found in bathrooms. And in moonshine makers:) ImageImageImage
On a sad note, nothing new about targeting for such weapons. Also traditionally.
