5/The wide scale deployment and production of several hundred SM-3 IB exo-atmospheric interceptors a year on USN Aegis combatants since 2017 is calling the Chinese 1st Island chain A2AD based on anti-ship ballistic missiles.
6/The Chinese anti-access air defense (A2AD) system is in turn a copy plus adaptation (W/ASBM) of the Russian A2AD systems.
Russian's A2AD system's role was to push E-3 Sentry AWACS and KC-135 tankers 250-to-350Km behind the FLOT so the Russians could control their own air space
7/...& keep A-10's and F-16's with laser guided munitions off the back of their troops.
8/The Russians have concerns for the SM-3, but not directly regards it's A2AD systems.
What the Russians are concerned about is America's deployment of enough SM-3 IIA ABM's to stop a simultaneous attack of EMP nuke equipped DPRK & Iranian ICBM's.
9/The production of the SM-3 IIA starts in 2021, building up to hundreds of interceptors a year.
The war stock goal is a 100% kill on a simultaneous Iranian & North Korean ICBM strike with four available ship-deployed SM-3 IIA's per whatever ICBM force these two powers have.
10/... (AKA Two volley's of two SM-3 IIB missiles per incoming ICBM on deployed Aegis combatants.)
If you are a Russian looking at what would be left over after a US 1st strike on a Russian nuclear force of 570 ICBM's, a 48 strategic bombers plus 12 subs in SLBM bastions...
11/...that is utterly terrifying come 2024(+).
A ragged Russian strategic 2nd strike hitting an intact US Navy Aegis ABM force could mostly bounce because the post 1st strike Russian C2 could not generate a coordinated attack to saturate it.
12/The Russians are now looking for surges of USN Aegis missile defense combatants off the US coasts in the same way NATO was looking for surges of Soviet Subs as a war indicator. And given the regular work ups and rotations of CVBG's, that's a problem.
13/Avangard hypersonic glide vehicle on IRBM's & ICBM's would enable a SEAD strike on the fixed ground based ABM radars supporting Aegis ships to allow a ragged Russian 2nd strike take out American cities and POL.
14/Russian Avangard HGV would not be a strategic 1st strike missile.
It is too slow and it's heat signature can be tracked from Geosynchronous orbit by US DSP satellites.
15/Russian nuclear doctrine is also focused on "demonstration/intimidation" single nuke strikes as a part of their strategic doctrine and Avangard delivers that capability...
...outside SM-6 and THAAD interceptor range.
16/This brings up the need to define hypersonics. A hypersonic glide vehicle is a term of art. There are two primary categories of hypersonic weapons
Hypersonic glide vehicles (HGV) & launched from a rocket before gliding to target. It is a type of depressed trajectory MaRV
17/ Hypersonic cruise missiles are powered by high-speed, air-breathing engines, or “scramjets,” after acquiring their target.
20/The combination of GMD & SM-3 upper layer and either a SM-6, THAAD, PAC-3 lower gives a two layer IRBM/ICBM defense that frustrates nuclear missile attack planning to the point no rational actor will do so without a massive saturation attack.
Hence HGV's to avoid GMD/SM-3.
21/American national interest in hypersonics are related to the Russian & Chinese A2AD systems & to the USAF Standoff Munitions Application Center (SMAC)
24/The US Military drive for hypersonics along with the low/stealthy stand off munitions like LRSAM seems to be develop the missile equivalent of a multi-trajectory artillery time on target (TOT) with integrated EW/cyber elements like MALD-X & Grey Wolf to overwhelm the A2AD C3I.
25/25 The USA has lost it's edge in electronic warfare compared to peer opponent A2AD systems.
But it has replaced part of what was lost via better planning & simulation used for multi-vector stand off munitions & decoys TOT against SAM batteries or what they are defending
@LarrySchweikart@GoroOuter If Sir Henry Phelps Brown & Sheila Hopkins did not address the massive shift in industrialization by electrification covering 1920 - 1965 they have a methodological problem.
The shift from line shaft & belt mechanical power transmission to electrical had huge productivity plus.
@LarrySchweikart@GoroOuter The widespread use of electric motors small enough to be connected directly to each piece of machinery meant any location with a concrete slab and electrical connections could be a factory.
It also made factories built post 1920 both easier to relocate and harder to destroy.
@LarrySchweikart@GoroOuter This is why the Soviet Union could relocate it's factories during the German invasion of 1941.
It is also why strategic bombing of German factories did not degrade production like pre-war air power theorists expected.
@downix@RupprechtDeino Structural carry modifications to the missile frame would be where the cost in the SM-6 upgrade would live.
However, compared to the new AIM-260 rocket ramjet design. An air-launched SM-6 would be longer ranged & have a much bigger installed base to work from upon introduction.
@downix@RupprechtDeino Vibration hardening from carrier launch & air carriage is another one of those "not easy" issues.
The AIM-120's carriage on F-16 wing tip hard points in the 1990's & 2000's in the various no-fly zones killed a generation of Slammer war shot dead, dead, dead.
@downix@RupprechtDeino Needs must when the devil drives. The SM-6 needs the delta vee a SM-3's 21 inch diameter booster can provide to get on a reciprocal trajectory for an HGV.
Granted, you are going to need ablative coating for the upper atmosphere as opposed to exoatmosphere flight.
Also granted
@downix@RupprechtDeino ... you are going to have issues with ionization for the radar at high supersonic speed requiring a back up sensor.
And likely the SM-6 stage atop the SM-3 booster will need a AMRAAM type multiple pulse solid rocket motor modification for the HGV intercept profile.
@downix@RupprechtDeino Raytheon's corporate engineering culture is capable of these sorts of modifications rapidly because they have had a stable and long experienced engineering team for the Standard missile that almost no other defense contractor in the world can match.
1/This is a tweet thread on the drone campaign inside the on-going Azeri-Armenian War.
Most have focused on the drone strike videos, myself included, but it is the C4ISR system behind it that makes it the Spanish Civil War of the 21st Century.
C4ISR is this thread's subject
2/Too appreciate the Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) portion of the Azeri drone campaign requires some background.
