An interesting radar signature caught with Sentinel-1 in todays images at (45.34947, 32.50320), Mayak, Crimea (09/05/2023).

Usually the C-band interference does not come in X-shape. It is also notable that there is no long range interference like in your average AA radars. If pinpointing where the X marks the spot by overlaying both Sentinel-1 and Sentinel-2 images, we're guided to this small spot with light colored items.

There is also an active radar dome complex nearby to the east.

Short🧵on new 🇷🇺 fortifications.

Russia has recently built a roughly 200km long uniform AT-ditch from Donetsk to Rostov. The building of this trench segment started in Dec 2022 and it was completed few weeks ago.

From Donetsk📌47.1676,39.5381
To Rostov-on-Don📌48.2002,38.0027 For now it is just the antitank-ditch complete with a few 'strongholds' along the way. It is highly likely to evolve in the liking of the trench line built in Luhansk: likely next to appear will be infantry trenches and with time dragons teeth accompanied by mine fields.

A thread🧵on Luhansk oblast mammoth 🇷🇺 trench project.

The start of this project was issued at the same time as the withdrawal from Kherson (end of oct).

I'll go through some of the data available and point the obvious *without going in too deep*.

1/20(n) The project has been going on already for over a month now and mostly all AT-trenches are now ready. Placement of dragon's teeth is still taking place and almost no infantry trenches have yet been completed in the most important strategic chokepoints.

So, based on the news of "Kherson's capital being moved to Henichesk" illuminates what we have seen in the past days and weeks.

Besides strategical importance, now it has also symbolical value.

Let's dig in a bit.

The P-47 has been in the back of my mind for a while now. Why fortify that one road so hard? Is it 100% just strategical importance? Now we know it isnt.

From Kherson to Henichesk the rule of thumb seems to be along P-47: every 7-12km one large defensive structure.

RU command gave an order at the end of October for troops to dig defensive structures near any significant town village or road.

Kherson-Zaporizhzia. Only new trenches.

A moderate thread on the russian trench-craze, documented with low-res Sentinel-2 images taken 5.11.2022. Let's start by looking at the first three ones. This timelapse covers three distinct trench complexes by the P-47 road (direction from north-west to south-east).

A look to Chaikovs'ke (Crimea) 🇷🇺 military unit and it's training ground. Focus on activity over a period of time as well as what conclusions can be drawn from this.

Mini 🧵

As I'm using low-res Sentinel images, here is a higher quality apple maps image to give a picture.

1/ The apple maps picture gives us an idea of what is there.
- Barracks for a whole unit
- Training grounds
- Storage halls and trucks
- Shooting grounds

The place has it's own google maps review page. Looks like they are/were Black Sea Fleet marines.

Activity check to an earthwalled part of a military training ground in Kirovske Raion (Crimea). Multiple vehicles can be seen moving in and out for an extended period of time.

1/ The earthwalled vehicle parking spot is part of an extended training ground which extends for quite a large area (approx 18km² freeform: 5.5km wide and 3.5km long).

NEW: Vesoloye airbase has seen quite a transformation in past months, and apparently it has gone quite under the radar for the #OSINT community. Activity is now at all time high in years with repairing existing structures, building new and equipping the base.

🧵- Thread.

1/ In a general timelapse of the base located at (45.57566, 34.28548) the transformation can clearly be seen. There are three zones that stick out quite clearly by the amount of moved earth:
- East: Circular form
- West: Old troop quarters
- North: Earthwalls
