We normally don’t comment on political statements, however in his 23 APR 2025 social media post US President Donald J. Trump made 9 (nine!) factually false or misleading statements about UA so we had to address that.

🧵w/ references ->
Image Statement #1: misleading.

Brief (and potentially incomplete) notes from a fresh interview w/ UA F-16 pilot:
- what missions F-16 and M2000 jets now perform
- their performance in UA
- RU glide bomb threat counteraction
- strike planning and intelligence
..and more
🧵
- the interviewee trained in the first group [of UA pilots to train on F-16]

My brief (and rough) notes from an interview w/ Andriy Kobzar - a (now retired, after injury) commander of a Ukrainian German-supplied PzH-2000 (). This video interview (in Ukrainian) adds details on top of the interesting text interview referenced below
🧵
Is RU-UA war an artillery war:
- yes
- the role is dominant, the tactics evolves
- for RU, FAB/UMPK gliding bombs are playing some of arty role (because they have a lot of them and a lot of aviation)

Second half of my quick notes from an interview w/ UA Air Force head of aviation Gen. Serhii Holubtsov (). For the notes on the first half of the interview see linked thread.

The second half was mostly about F-16s and a little bit about JAS 39 Gripen.
🧵
F-16
Munitions:
- all airplanes will have improved "sight" (in Ukrainian usually that mean improved radar - no further details given), will [also] have pods for ground attack targeting

Quick notes from an interview w/ UA Air Force head of aviation Serhii Holubtsov (published today).

I normally don't do translations, but I see a lot of mistranslations/misinterpretations of this interview - thus this thread.

Notes of 1st half below🧵:
JDAM and other guided bomb use by UA:
- the quantities are limited thus limited effect on the battlefield
- enough airplanes have been modified to use them by now
- domestically UA produced glide/guide kits to be tested "in a few weeks"

Brief update (with geolocations) on Malovodne-Burne (Mariupol) rail line construction by RU occupational forces.

Based on geolocated media footage we confirm that in Novomykhailivka area there will be a railroad segment (of undetermined length) with 2 parallel tracks.
🧵⬇️ Image Geolocation 1: video taken at Malovodne-Burne rail / hwy (T0508) intersection near Novomykhailivka.

RU patrol ship Sergei Kotov was attacked by UA USVs on 5 MAR 2024.

Together w/ @COUPSURE, @kromark, @LoLManya we find the likely attack location based on AIS coordinates of nearby vessels & sat. imagery:

Image First, we noticed a nearby cargo vessel with a peculiar shape of cranes. We looked through the vessels near Kerch Strait w/ AIS on and found a likely candidate: TWIN STAR () marinetraffic.com/en/ais/details…

On 14 FEB 2024 RU ship Caesar Kunikov was sunk by UA USVs off Crimea coast.

While *qualitative* location was immediately determined (), *precise* location wasn't.

Here, we computationally determine the precise location of the USV and the ship.

Thread🧵👇
Image Using computational photography, we determined the location of the USV/POV and Caesar Kunikov ship.

POV/USV ≈ 44.38733, 33.88549
ship ≈ 44.38881, 33.88481

They were located roughly 1.6-1.8 km off the Crimea coast.

Fire (planned or accidental) was reported tonight (07 FEB 2024) at Votkinsk Machine Building Plant test site.

Based on triangulation of available imagery we estimate its location within the test site:

rocket engine testing facility ~ 56.9386, 53.4142

Image The plant itself () manufactures various kinds of ballistic missiles ranging from tactical/SRBMs (Tochka-U, Iskander-M) all the way to ICBMs like Topol-M.en.wikipedia.org/wiki/Votkinsk_…

On early morning 02 FEB 2024 RU corvette “Ivanovets” was attacked and sunk by UA USVs ().

Based on star positions seen in the extended video () we time and geolocate it:

In this thread we will do a deep dive on RU construction projects in occupied south-eastern Ukraine:
- new railway
- existing highway renovation
- rebuilt natural gas pipeline
- new water pipeline Image Image

RU IL-76 crashed earlier today (24 JAN 2024) in Belgorod oblast.

Analysis of the sound from a video recording of the crash reveals crash location (based on sound/light delay): ~50.888, 37.340

There likely was an explosion within first ~0.3 seconds of the crash.

@GeoConfirmed
Image Also, evidently, the aircraft was already losing parts / disintegrating shortly before the crash as seen in the video (obvious in higher quality video downloaded directly from Telegram, e.g. ): t.me/astrapress/467…

On 13 AUG 2023 RU military boarded Sukru Okan bulker ship in Black Sea close to Turkish coast.

In this thread we computationally determine where and when this likely happened by analysis of publicly available videos combined with AIS vessel tracking data.

Image The key of this analysis was determination (by computational analysis of Sun position) of the time when the two published videos showing boarding and deboarding of RU military were taken.

This allows the videos to be approximately mapped onto the available AIS track. Image

Significant RU air defense activity was reported in Rostov-on-Don (RU) within last 7 days.

Based on social media photo/video evidence we determined the air defense location to (roughly) the north east side of Rostov International Airport (~ 47.265, 39.830).

New road and possibly bridge construction can be seen in Sentinel-2 imagery near RU-occupied Staromar'ivka, Donetsk Oblast. May be related to reported RU railroad branch construction (below).

Possible bridge construction: ~47.4236, 37.8615

Sentinel-2 data for Vesele airbase in RU-occupied Crimea is now available.

Apparent burn marks in the area that looks like a newly constructed (after JUN 6) ammunition storage in the north-west corner of the airbase.

Bavovna/explosions/shooting is being reported in RU-occupied Sebastopol. RU sources report a USV (marine drones) attack.

(verification and geolocation a little later)

So far two explosion-like sounds have been reported (at 03:31 and 03:44). t.me/Crimeanwind/28…

The latest Ukraine assistance package included 4000 "Zuni aircraft rockets"(defense.gov/News/Releases/…).

What's interesting about them is that they have a laser guided option developed about a decade ago by MBDA in cooperation with Elbit Systems, General Dynamics, and Honeywell

-> Even basic unguided Zuni rockets would be useful to Ukraine and could be used just like S-8 or S-13 are used now (see illustration below). One advantage of Zuni is their range is almost double that of S-8/13.

However, these rockets have a laser guided precision option too

Reports of explosions in Melitopol

Viewpoint at (46.843526,35.358159)

Looking towards a number of large warehouses (purple arrow shows approximate direction below)

@GeoConfirmed Image -> Presumably from the same event: "something's burning at Gidromash plant in Melitopol".

I'm 95% sure about this camera geolocation: (46.848568, 35.364974)

No street view, but Yandex map gives good view of the facades matching the photo

About Sea Sparrow surface-air missile adaptation to UA Buk-M1 SAM systems that Politico has reported yesterday (politico.com/news/2023/01/0…).

It's not as surprising as it may seem at first.

In fact, Raytheon (Sea Sparrow manufacturer) and Polish WZU-2 worked on this in 2007+

-> ImageImage As early as 2007 Wojskowe Zaklady Usbrojenia Nr 2 (WZU-2, Grudziadz, Poland) announced working on adapting Sea Sparrow RIM-7 missile to 2K12 Kub (SA-6) SAM system -- Buk predecessor. In 2012 a prototype was shown using RIM-162 ESSM missile on 2P25 Kub launcher.
