Video. The 110th Mechanized Brigade released a video of the destruction of a russian Su-25 jet on June 10.

Bravo, warriors!

I'm not actually sure you can confirm loss from that movie. Couldn't see anything to be honest?

At the end, there is a big black plume rising from the ground (at about 1/4 from the right side of the video). Of course, no guarantee this is an SU-25 being smoked, though the coincidence with all that is happening is quite high ......

When that missile gets launched would the aircraft it's targeting be aware immediately or does it home entirely passively? A lot of the time the target seems to be unaware.

According to their information, air defense systems are also moved from Crimea to Belgorod region of Russia.


​​​​​​​

What does Russia have more on heavy stuff than the AD systems (after effectively abondonning the Sevastopol navy harbor) ?

Looks like once the AD systems have left, there is little stuff left to effectively defend Crimea against any party wanting to take possession of the Crimea. IE, without AD systems, any heavy army & airforce stuff will be vulnerable against air attacks.

The start of "shortening the frontline", as it was called 80 years ago ? Given Crimea was/is extremely important for Putty, it would be a big LoF for him and effectively crumbling the SMO.

Depends on the missile's guidance system. If it is a passive heat-seeker e.g. Stinger, then no warning. If it is an active radar-guided unit, then certainly and am unsure about whether laser-guided missiles.can be detected. The pilot will be looking for smoke-trails from missiles, but that's going to be of limited use due to restricted vision.

Interesting interview with Prof Justin Bronk of RUSI - F-16 covered 14:00 > 24:00

https://www.youtube.com/watch?v=72QpCqBgrPU

How in the hell does your country get invaded and you not go to full mobilization?
Justin remarks on this early in the video and then goes on to discuss the 500,000 Russians in theater. (It appears that Ukraine has 200,000 under arms?)
EDIT TO ADD
Mooch is the goods.
A few more points to take away from Justin's very informative brief.
1. Crew survival a huge benefit in Western Armor
2. Russians are a learning military: have figured out EW answer to GPS guided munitions.
3. 152mm Russian laser guided howitzer shells, drones with lasers designating.
4. ATACMS is not a GPS cripple.
5. EUCOM's posture has become in the last two decades an avenue to project power into CENTCOM, and Justin sees that as its current prime purpose. Interesting take.
6. Over 8,000+ missile strikes on Ukraine since war started. And Ukraine is still in the fight.
My caustic observation is "Air Power au outrance advocates need to pay attention to that"
Many other issues raised, and the training piece was a good one.

7. Any of us who know the business already knew that F-16 isn't a silver bullet, and I appreciated Justin re-emphasizing that point.

Germany with allies will transfer 100 missiles for Patriot air defense systems to Ukraine, - German Defense Ministry head Pistorius.

Video 🍿 TEARS OF THE ORC.

“My legs can’t move and I really want to live. We’ll give up, we’ll surrender,that’s it.”

Orc Oleg Vesnin from the 83rd Air Assault Brigade of the russian army told how difficult it is for the orcs at the front.
​​​​​​​
“Three days without food, without water. I’m very thirsty,” — he complains.

The wounded commander remained with him, and the third orc “left behind, he probably died.” Near the place where they are now, there were five wounded and four more dead orcs.

Vesnin, together with a wounded commander with the call sign “Butcher,” is going to surrender in order to “live at least a little longer.”

Video 🇷🇺 Putin's Borisoglebsk-2 is done

One of the most expensive targets destroyed by FPV 💥

The Borisoglebsk-2 electronic warfare system is one of the most powerful in Russian service. The cost reaches 200,000,000 dollars.

One of the vehicles of this complex was destroyed by the soldiers of the Taistra unit of the 10th Separate Mechanized Brigade.

I was astounded at the image resolution of the recently destroyed SU-57. I assume that is a satellite photo as the overhead position was the same in the before and after pictures. If this is the resolution that is sent out to the general public the actual must be astounding. Where I'm going is how are these targets, such as the EWS, found? It must be target sharing from NATO to the Ukrainians. Hopefully this is real time information and access is expanded......

If you are referring to the image posted by ORAC #11043, with text "@KHERSONDESIGNER",
it is not reality, it is not a HiRes sat picture. It is computer rendered (Photoshop, game graphics....)

There is a real-ish before/after sat image of the damaged SU-57 posted by ORAC #11006

KHERSONDESIGNER on X has a nice render of a Mirage with Ukrainian roundels :)

One of the characteristics of active EW is sending out a huge amount of radio signals. Just home in / triangular on that, and you have your EWS .......

And, indeed the SU-57 picture resolution is astonishing. Better than I have ever seen before.

On second glance it looks like a digital render, or at least a very ‘improved image’ . A google search for ‘ Khersondesigner’ brings up a few more pieces of digital artwork, a Backfire being shot down and an attack on the Crimea bridge. Be good if it was a satellite image though..

Media are expecting an announcement in the next day of American partriot to ukraine. Expected to be one currently in poland this is number 6. Netherlands announced part of another launchers + radars (7th)

Javier Mieli (argentinian president) has announced they are wanting to send thier 5 super Étendards to ukraine

Satellite ground image resolution
 
Wikipedia: KH-11 KENNEN Resolution and ground sample distance

A perfect 2.4-meter (94 in) mirror observing in the visual spectrum (i.e. at a wavelength of 500 nm) has a diffraction limited resolution of around 0.05 arcsec, which from an orbital altitude of 250 km (160 mi) corresponds to a ground sample distance of 6 cm (2.4 in). Operational resolution should be worse due to effects of the atmospheric turbulence.
This references Fried, D. L. (October 1966). "Optical Resolution Through a Randomly Inhomogeneous Medium for Very Long and Very Short Exposures". Journal of the Optical Society of America. 56 (10): 1372–1379.

An appropriate Gaussian blur on the image might have made it more believable.

One of the interesting things about SpaceX's 'Starship' is that, if successful, it will be able to carry substantially larger diameter mirrors into orbit (payload bay is 8 metres in diameter) , enabling the taking of higher resolution images from orbit. That said, large monolithic mirrors are both difficult and expensive to manufacture, so it probably makes more sense to produce a segmented mirror like the James Webb Space telescope, and add adaptive optics - which the Starship could happily carry with its vast payload capacity. A seven metre aperture on a mirror gives a theoretical best ground sample distance of roughly 2.5 cm.

Of course, aircraft don't fly at 250km altitude, and can use smaller aperture optics with image stabilisation and adaptive optics to get good images. U2s are not the only examples of this. Flying directly over a Russian airbase might not be a good idea.

I think KH-11 Kennen images in reality end up with a 10-15cm ground sample distance.

The Ukrainians have been sending, if not swarms, multiple UAVs to attack such targets. With the latency of the precise positioning of targets such as individual aircraft it does not stretch the imagination to presume a some are equipped with satellite, or even Russian mobile phone net, linked cameras for pre-strike recce ahead of the bombers, and those towards the end for post-strike recce before self-immolation.

When you don’t have satellites other options come into play.

Not saying that occurred here - but they’d be stupid not too….

ORAC 12th June 2024 14:28

They can’t have many left, that’s 6 gone in 72 hours.

A S-300 system near Belbek and two S-400 systems near Belbek and Sevastopol were struck this night, The Ukrainian General Staff reports.

It is rumoured that two (and a possible third) radars were destroyed.

Atesh partisan movement reports destroying a satellite communication station in the Moscow region of Russia.

The sabotage was carried out on the territory of the 584th Guards Anti-Aircraft Missile Regiment (military unit No. 62845) in the city of Klin, the movement reports.

According to them, this has weakened the whole air defense system of Moscow region.

📷 After and before: Atesh
