Now that Ukraine has confirmed its use of a S-200/SA-5 Gammon.

We can discuss what this video tells us about the RuAF A-50 crew, the planes equipment and what shot it down.

First, it shows 80 plus seconds of irregular countermeasures release.

1/
80 seconds is neither consistent with a computer controlled electronic countermeasures system nor with Russian friendly fire incident as Buk, S-300, S-350, and S-400 missile travel to between Mach 6.7 to Mach 7 within their engagement envelope.

We saw flares in the video, but it is certain that radar chaff was also released, but was unseen in the dark.

As a 5V28 missile of the S-200/SA-5 has a radar signature rivaling a Mig-25 Foxbat.

This extended A-50 countermeasures release _is_ consistent with a S-200

...engagement with radar warning receiver blaring at a VKS pilot that a 5N62M SQUARE PAIR was in its initial fine tracking to get accurate range and angle for a Mach 3 missile at over 250 km.

The A-50 crew would start toggling expendable countermeasures when SQUARE PAIR radar dropped range finding modulation into pure 'monochromatic' carrier wave illumination.

...and in the clipped text below

Various accounts say the VKS A-50 crew was climbing after take off at the time of the missile attack.

The crew should have dived - HARD - to get below the radar horizon of the S-200 5V28 missile shot and dumped most of the expendable

...countermeasures in the final dozen seconds of the engagement to fill the seeker engagement basket with expendable decoys.

The A-50 crew did neither because it lacked both modern electronic warfare equipment and training.

7/
By way of comparison, the Late Cold War era EF-111A Ravens and EA-6B Prowler's had the S-200/SA-5's measure during Operation El Dorado Canyon in 1986.

Could there be something else going on here?

Air Power Australia reported that the S-200 was exported to Belarus, Uzbekistan, Bulgaria, the Ukraine, Czechoslovakia, Hungary, Poland, India, North Korea, Libya, Syria, and more recently Iran.

Poland did a digital upgrade to their S-200/SA-5 Gammon system before it was withdrawn from service.

It was reportedly in storage when the Russo-Ukrainian War began.

And Air Power Australia also reported that hybrid digitized interfaces & software

...were available for the S-300PMU2 Favorit / SA-20 Gargoyle & S-400 Triumf / SA-21 to control the S-200 Vega/SA-5 Gammon and its 5N62 Square Pair engagement radar so the latter would only illuminate/update the 5V28 missile.

See⬇️

11/ Image
Given that Ukraine has been provided Integrated Air and Missile Defense (IAMD) Battle Command System (IBCS) Engagement Operations Center (EOC) from the USA.

It's likely IAMD was plugged into the SQUARE PAIR for an illumination/uplink only kill.

12/

Think of it as another "Franken-SAM" with the S-200 in the same firing role as the proposed Patriot and S-300 Franken-SAM hybrid.

If only because there are more 5V28 missile available to shoot from East European NATO stocks than S-300's 5V55 missiles.

Let us be clear what has happened here.

Ukraine has a drone armed merchant raider lose in the Mediterranean hunting Russian shadow tankers.

Upshot: There will be more elsewhere on the world's oceans in the near future effecting maritime trade.

2025 Merchant Armed Raider 🧵
1/
@grok answered the following questions for me:

" Please summarize the pre-World War 1 to 1942 career of merchant armed raiders and compare that data to Ukraine's recent drone attack in the Mediterranean with a drone armed commercial vessel."

2/ Image

This is @grok's final summary:

"In essence, Ukraine's approach modernizes the raider concept—swapping guns for drones and merchant disguises for stealthy launches— but lacks the historical volume due to the conflict's constraints.

US Ground force flag ranks deny this 2025 reality 🤡⬇️

"The Ukraine war has exposed a large and increasing gap between Western reconnaissance doctrine and modern conventional battlefield reality.
1/3
In Donetsk, reconnaissance operators face constant drone surveillance, electromagnetic degradation, and hyper-local combat conditions that invalidate long-held assumptions about stealth and standoff intelligence, surveillance, and reconnaissance (ISR).

2/3
This article contends that NATO must, with urgency, reform its reconnaissance doctrine, training, and force structure to survive and efficiently operate in a drone-saturated battlefield."

I said this about the US Navy in 2023 (⬇️)

....and the institutional failures on display in the USS Truman CVBG Red Sea deployment proved me correct in 2025.

1/2
Every competent USN surface officer knows in their gut an anti-aircraft cruiser should not be operating with downed identification friend or foe (IFF) and Link-16 data link with no E-2 Hawkeye AEW support.

Those officers know in their guts that radar skin paints alone from their ship's SPY-1 will be borderline for high tempo engagements...

Just...listen...to this video clip with your eyes closed.

The predominant sound isn't artillery.
It isn't assault rifles.

It is the scream of drone rotors coming close, punctuated with the explosion of the drone upon impact.

1/3
That sound drama isn't World War One or any "medium intensity" conflict since 1918.

It is the sound of how 21st century Peer-to-Peer conflict is fought.

A conflict Western ground militaries are obsolescent in equipment to face.

2/3
That Russo-Ukraine War video is a soundscape US Army National Training Centers are too obsolete/incapable of replicating, because US Army flag ranks are allergic to training with high densities of small/cheap/many FPV drones.

WW2 is calling again with Ukraine developing Drone version of SHORAN.

SHORAN was a WW2 blind bombing system using two radio stations and an electromechanical computer.

In 1938 an RCA engineer named Stuart William Seeley, while attempting to remove "ghost" signals from an experimental television system, discovered he could measure distances

...by time differences in radio reception.

Instead of building a radar unit with this discovery, he proposed using this technique for precision ground-based radio beacon navigation bombing aid.

One the DCMA quality inspectors on my team worked at an EMALS contractor in Texas.

I can't say more than the Chinese tested their EMALS at subsystem level (unlike the USN) with the knowledge the four catapults needed to be independent of each other for operations,

EMALS🧵
1/5
...based on how the USN f--ked up their EMALS design.

That is, when any single EMALS catapult on the Ford class goes down for any reason. They all can't be used.

2/5
As strategypage dot com put it in 2019:

"EMALS proved less reliable than the older steam catapult, more labor intensive to operate, put more stress on launched aircraft than expected and due to a basic design flaw if one EMALS catapult becomes inoperable,
