Today Russian Navy corvette Soobrazitelny 531 intervened to make German media, politicians and possibly coast guard stay away from a shadow tanker in waters between Denmark and Germany. Details from Swedish politician: a Greenpeace protest was under way, Russian corvette closed in at high speed, initially not replying to radio from German Coast Guard. German CG then escorted activists/politicians/media away.

Ie, Russia interrupted western democratic activities.

Russia is jamming Baltic Sea - 6th proof, 4th method.

Pskov, Kaliningrad and Kingisepp stand out as highly likely spots for the jammers, found by analyzing NISAR satellite imagery.

Method is copied from work by @SeanGorman and verified by identifying a known jammer, +/- 2.5km🧵 Method is best described by @SeanGorman in this article, my inspiration.

Short version, jammers produce interference seen by the radar, bearings are taken and combining several such it is possible to compute a center position and its uncertainty.

One of the Russian GPS spoofers around St Petersburg sports what looks like an aim function.

There is a realistic possibility this has been used to drive Ukrainian attack drones into NATO territory.

So far, I only have two anecdotes to show for it, data collection ongoing.

🧵 Last months have seen some drones stray into eg Finland, Estonia and latest Latvia.

While it is an obvious expected function of a military spoofer to send a drone astray, to my knowledge it has not been shown to happen.

I am not showing that, yet. But there are circumstances.

The hypothesis that last summers telecom sabotage campaign in south Sweden was in fact aimed at dual use military installations is strengthened.

Masts facing southeastern Baltic and Kaliningrad were hit.

Finland is now implementing the tech. It is not public whether SE uses it.

Baltic Sea is about to welcome false flagged tanker GRIF 9332028 heading for Russia

She is 19 years old and was last inspected by Russia in 2024 with deficiencies in life boats, doors and "dangerous areas"

Sanctioned by EU, UK and Switzerland. Passed inside DK without a hiccup GRIF claims to be flagged in Madagascar. Madagascar on the other hand denies having a international ship registry =)

NATO has started broadcasting a regular request for the reporting of suspicious observations from mariners in Baltic Sea.

Not sure when it started, but a while ago. Thanks anon follower for the recording! =) Full text:

... in the Baltic Sea region in coordination with NATO Baltic nations to safeguard safety and security, freedom of navigation and the security of undersea infrastructure.....1/2

Soon, an oil-bro heavy on shorts will show you a screendump or even recordings from your favorite AIS-service stating that Hormuz strait is open.

These are the ships "transiting". Ask you local sailor if shipping looks like that.

Repeat after me: real data or it did not happen.

Someone is spoofing ships to make it look like they are entering Hormuz Strait from Indian ocean.

This is false. Ships do not move like this.

Zoomed out version from Marinetraffic. Zoom in version above^

4 days ago Baltic States + UK wrote a letter interpreted as "Baltic Sea closing for shadow fleet".

No sanctioned tanker has arrived since (unusual*) but coming 24-36h the claim will get its first test with 5 sanctioned tankers inbound.

https://twitter.com/auonsson/status/2016282879999836439

* It is unusual to not see daily sanctioned tanker arrive to Baltic Sea, usually a few each day.

But, the last 4 days lull ismight be explained by weather: Atlantic storms, low temperature and an increasingly frozen Gulf of Finland.

Underappreciated fact:

The paths and positions of the cable damages around New Years 2026 were to most of Estonia's internet backbone routes.

Had it fully succeeded/happened by accident (lol) Estonia would have been left with a crippled connectivity.

I just deleted a post where I had misread a press release.

5 cables have been damaged, but 3 of those from storm conditions. I might not have been that wrong.

There is a SE-EE incident and a FI-EE incident.

The SE-FI is described as two breaks on the same cable last I read.

As per usual the details, allusions and contexts are vague in news and statements.

Russian logistics ship ADLER is at anchor IN Sweden.

Possibly broken down. Usually runs heavy weapons to Russian bases in Africa / Middle East.

Was inspected by military aircraft 2h ago. Swedish Coast Guard just arrived to area.

Tnx @butafly over at the better site. @butafly Coast Guard patrol is about to dock in Höganäs, port a few kms south.

Here they will likely pick up more staff for whatever they plan.

Guess: Nationella Insatsstyrkan or something similar. NI are police, but carry proper guns. Or, a cadre of really nitpicky bureaucrats =)

@pmolpmol lists three ships interesting as suspected drone carriers in last night attack on Copenhagen Airport.

In this thread, I will argue that Russian ship ASTROL 1 is an excellent fit.

Right time, right type, erratic track just before attack, highly suspicious background. Article that led me down this rabbit hole, by @pmolpmol nyheder.tv2.dk/live/krimi/202…

Copenhagen Airport is closed for operations because of drones in the air.

Northern Europes most busy airport. Plane diverting last minute.

A Russian brand new fishing boat is almost blocking Öresund strait.

They seemingly lost propulsion 4 hours ago, drifted north towards the very narrow channels (~300m) but seem to have anchored.

Swedish coast guard and police have been at scene.

AIS-caveats apply. A Russian brand new fishing boat is almost blocking Öresund strait.

This is the main logistics hub for armaments into Ukraine.

Tanker (and hence fighters) inbound, Italian AEW&C inbound.

I thought I had found indications of a targeted GNSS jamming attack against president von der Leyen's aircraft this Sunday.

Then I disproved my own hypothesis. Here's how!

This is common for me, I usually don't show it because it takes a lot of effort to explain also 0-results Hypothesis: if vdLeyen-flight was jammed by a directional jammer other aircraft in the emission cone would also be affected

I got the idea upon looking at an animation by @lemonodor

Marked flight began reporting bad GPS-values just as the pilot of vdL reported issues over radio

Swedish island Gotland is completely without power, for the second time in two weeks.

Gotland is considered paramount to NATO control of Baltic Sea.

As far as I know last outage is still being analyzed and cause is not known.

svt.se/nyheter/lokalt… Power company now claims lightning strike as cause.

Article linked was updated.

Pilot of the aircraft carrying president von der Leyen experienced GPS issues as they approached Plovdiv airport, Bulgaria Sun Aug 31.

Recordings of tower and plane comms are clear.

Transponder reported good GPS-signal and is likely separate from the instrument pilots used. Half an hour after first reporting GPS-issues the aircraft of von der Leyen is taxiing on Plovdiv airport as the pilot repeats "we had GPS-issues" and thanks the flight controller for the support.

Full recordings with additional comms available at liveatc.net

The plane carrying EU top Ursula von der Leyen was forced to land manually after being hit by GPS/GNSS jamming.

News texts seem to indicate it was directed specifically at Von der Leyen and the airport Plovdiv.

"GPS around airport was knocked out for an hour."

Stockholm-Helsinki ferry SILJA SERENADE made a sharp turn for unknown reasons night between Tu & We. Owner claims weather and collision avoidance. There were damages to loose items.

But there was no other ship on AIS, no sharp turn registered and weather was calm. Calm weather is substantiated by an anonymous maritime professional witness to YLE.

Heavy jamming? Malfunctions? Dark ship in the way? Submarine? Possible explanations are many but the one from the ferry company seem unfinished.

Tnx @akihheikkinen!

Russian destroyer Vice Admiral Kulakov fended of a drone threat Monday in Fehmarn Belt, Baltic Sea, Danish EEZ.

The large ship made evasive maneuvers, employed some anti-drone machine and manned and aimed lighter guns.

All according to local news: archive.is/G5kot DK Navy observed. Thanks anon follower.
