This is going to be a JDAM-ER 🧵to try and explain the battlefield impact of the weapon in the Ukrainian Air Force, AKA the PSU.

Essentially this is a glide bomb kit version of the ubiquitous JDAM that pairs well with the PSU Su-24 fleet, the Soviet answer to the USAF F-111.
1/8
The ability of the Su-24 to fly transonic on the deck in a low density integrated air defense environment means there are a lot of low level holes in radar coverage to lob a stick of glide bombs out of, at high speed, inside occupied Ukraine.

2/8
The PSU would be able to hit a number of just over 100 km Russian logistical targets with a 60 km low altitude penetration & JDAM-ER toss bomb attack profile.

See examples⬇️

3/8
The JDAM-ER is the result of a US-Australian cooperation agreement where in the Australians developed a glide kit for the Boeing JDAM five years ago that comes in several flavors & ranges.

It is unclear if the jet engine version of the JDAM-ER will be provided to the PSU.

4/8 Image
If jet powered JDAM-ER was provided, PSU Su-24's don't have to enter occupied Ukrainian air space to kill Russian logistical targets.

160 nautical miles is ~296 km, just shy of the ATACMS 300km.

5/8
And if it wasn't.

The Russian Army should still worried about the Kerch Straits Bridge catching some JDAM-ER as they have GMLRS style microelectromechanical systems (MEMS) inertial measurement units (IMU) that let them ignore Russian GPS jamming.

6/8

One more thing, unless the Russians park a 24/7 A-50 Mainstay AWACS orbit over Crimea.

The SU-24 plus JDAM-ER combination just made Sevastopol untenable as a fleet base.

The JDAM-ER MEMS inertial guidance is as accurate as GMLRS, enough to plink warships at their piers...
7/8 ImageImageImage
...even if the GPS is jammed.

The arrival of JDAM-ER in the PSU's SU-24 Fleet is when Russia's lack of air superiority in Ukraine will kill them.

Russia faces a logistical dilemma in occupied Ukraine for which it has no good solutions.

Crimea is a de facto island fed by road and rail bridges Ukraine can now destroy at will, and Russia cannot stop.

And Ukraine is destroying those bridges.

1/ Image
Russia's air defense has suffered a nearly complete "Lanchester Square Collapse" proximate with the Ukrainian mass deployment of both 150 km range AI truck hunting drones and bridge busting FP-2 OWA drones.

Any route Russian trucks take to Crimea will result in parking lots near replacement pontoon bridging for both those kinds of drones to exploit.

"Trucks that mass together...die together.

Saving Space Access From Kessler Syndrome

Elon Musk’s plan for XAI satellite data centers, and all use of space for any purpose, faces inevitable collapse until a solution emerges for the problem of Kessler Syndrome (see Wikipedia). 🧵

1/
This will occur when enough collisions of small orbital debris pieces from old dead satellites hits the steadily increasing number of new satellites until the whole thing spirals into mass collisions.

Kessler Syndrome computes that this will destroy all existing

...communications, navigation, observation and research satellites in low/medium orbit, and prevent all further satellites launched, for 40+ years, until enough pieces fall out of orbit into the Earth’s atmosphere.

Do you remember all the 2023 US Navalist accounts o X that screamed at @johnkonrad and I about pointing out the containerized anti-ship OWA drone threat to the US fleet.

Welcome to 2026 Ukrainian anti-ship OWA drone threat, you US Navalist yo-yo's. ⬇️

"Operation Spiderweb with Chinese characteristics" is coming for you all, and we have the receipts.

We need a whole lot of air defense guns everywhere to stop drones that you guys still refuse to fund.

2/ Image
For fun and reference of guns versus missile air defense, this YouTube test scenario pits 100 Shahed-136 one-way attack drones against the historic US Navy Task Force 38.1 from 1944.

Just...no. The 8th AF fudged its accuracy numbers.

It excluded "gross error" bombing runs beyond 3,000 feet from the target. Which were above 10% of all 1944 bombing runs.

Below, the inner circle is what a 1944 1,000 foot (304m) CEP in WW2 looked like when dropped from 400(+) four engine heavy bombers.

Using this document:

THE UNITED STATES STRATEGIC BOMBING SURVEY
Bombing Accuracy, USAAF Heavy and Medium Bombers in the ETO
MILITARY ANALYSIS DIVISION
First Edition 3 November 1945
Second Edition January 1947

You find both mission failures & gross errors were "excluded data"
2/ Image
And that both increased altitude and the number of combat boxes involved made CEP worse.

There are sound photographic reasons I'm talking about Russia's domestic fuel tanker supply distribution chain breaking down.

Dead tanker trucks can't move fuel.

Plus additional tanker trucks diverted & moving from 🇷🇺 to 🇺🇦 can't deliver fuel domestically either.

Fuel🧵

For additional photographic proof of 🇷🇺 tanker truck supply distribution breaking down, see here in Belgorod:

And see here elsewhere in Crimea:

This manpower sweep problem is actually a lot worse for the Russians than Western military intelligence is capable of giving credit.

It takes a Russian labor gang about 3 hours to load 16 tons of wooden boxes w/o a convenient box car to truck line up. (below upper right)

Because the Russian Army doesn't use pallets, forklifts, telehandlers nor D-rings anywhere in their supply chain to strap down pallet loads.

You need massive numbers of conscripts to load and unload from train cars to trucks & vice versa.

See⬇️
2/
This has a whole lot of knock on effects in how the non-mechanized Russian supply system works in the age of GMLRS & drones.

You see here a commercial to tactical truck swap of wooden boxes in the Russian Army operational/strategic depths.
