[ 1/31 ] 🧵 Time for yet another megathread of my favourite satellite pics. This time I have 123 images processed by me in 2025 *. Various dates, random places. Most of them were taken by Sentinel-2, some by S-3 and one or two by Landsat. *There's one more pic that isn't mine, but it's so good 😊

Happy 2026 everyone! May we find all the subs this year

Saab wins order from France for two GlobalEye surveillance planes reut.rs/4sgWLFK

And another 3 for the Poseidon Pool. Love to see it! Not sure why the picture shows an Australian P-8A (especially since its procurement wasn't through FMS); III3B2 hints maybe?

Important account to follow!

The Elephant's Trunk Nebula (IC 1396A), a late Autumn target. 8h 31′ of poor quality data (moonlight, clouds, high humidity, etc.) Taken with Celestron RASA 8", ASI533MC Pro & L-eXtreme F2.

Oh lord, here they're coming!

The АРКТУР SSBN concept is the strongest contestant for my no 1 sub spot overtaking Pr 971/885. Very interesting concept with СУРРОГАТ-В LUUV/-AUV and completely overhauled tail section/ propulsion, designed for the (upcoming) race to the Arctic. Though it unfortunately might stay a concept only

Also interesting to see the building progress of Pr 22220 Nuclear-powered icebreaker "ЧУКОТКА" in the background over the last months

For the last four years Max Verstappen was unstoppable but this year, Lando Norris made it. Is this a sign we're going to see big battles in 2026 between Max, Lando and Oscar? Excited for the new 2026 rules and a lot of new teams/constructors joining. *Here are some 2024 McLaren front wings*

"...[T]he RAF plans to deploy Voyager tankers towards the 24th and 25th of the month in order to refuel the inbound cargo aircraft." Other intelligence sources state, that this is one of the biggest annual airlift operations stretching from Alaska to Japan and beyond God speed!

Very interesting pictures of a Magura V7 (I believe) with AIM-9L's Also interesting to see double Starlink antennas

First quality public photo of China’s trimaran semi-sub. Second image is my sketch based on satellite imagery while it was hidden under tarps(!). Of course some differences, but I was right it is a semi-sub(!). Overall pleased how much I got right

6/ The Russian economy continues to show signs of fracturing as Russia continues to prioritize its wartime economy over stability. Balloons from Belarusian airspace continued incursions into NATO airspace in Lithuania overnight on November 28 to 29.

Please correct me if I am wrong, but at the very least the robo arms are missing/not installed @covertshores.bsky.social

The Russian spy ship, designated Yantar, has been spotted by British authorities loitering near Scotland after entering British water intermittently over the previous weeks 🇷🇺 www.navalnews.com/naval-news/2...

Let's see if they're heading up North or maybe stopping by at Yantar for a quick visit

UK 🇬🇧 Ministry of Defence (MOD) image of Russian spy ship Yantar, presumably in or near UK waters. Note that the ROV (remote operated vehicle, a deep-sea robot) A-frame is deployed (red). It’s doing something on the seabed. Also two new radomes (yellow)

This would be very interesting. Someone who I have not seen in quite the while Last time VAdm Paromov and Sergey Balk limped back to Kronstadt and Lomonosov after an intensive deployment to the Med, back when Tartus was still a thing..... Though this was already in 2023, I am certain

Interesting to see the UK in discussions with Hensoldt (for potential RC135 successor) PEGASUS. Though the Eurohawk/ PEGASUS story has not been all that glory either. At this point one has to wonder, whether a couple AAS birds would be a better choice (only considering the technology for a moment)

Interesting area closures in the Barents and White Seas: red | in effect 17-18 November 03:00-15:00 green | in effect 19-20 November 03:00-15:00 blue | in effect 22-23 November 03:00-17:00 *correction; changed second 'green' to 'blue'

[1/10] Is there enough time for future RF Navy Severodvinsk II-class nuclear-powered cruise missile submarine Perm to complete builder's sea trials + state testing in the White Sea and then be commissioned by the end of 2025?

Pr 971 and Pr 885 probably one of the sleekest and most beautiful designs for submarines in my opinion.

RF Navy Northern Fleet Yantar-class special-purpose auxiliary vessel Yantar departed port on 25 October and was operating in the North Sea earlier this week; monitored by Dutch Navy assets (HNLMS Friesland + HNLMS Snellius) bsky.app/profile/spec... www.defensie.nl/actueel/nieu...

@auonsson.bsky.social Maybe this is also related to the Balti Sea AIS anomaly that popped up yesterday?

Is there a way to figure out, what exercise/activity is currently going on here? @spectrecrouton.bsky.social @mrfrantarelli.bsky.social Asking for a friend

I was hoping I'd get around to doing a full review in the next month or so, once the vessels had gone home - but anyway, just to highlight something: there were, since August, something like 6 or 7 other potential test windows, based on vessel/aircraft movements. Below just shows since September.

I am a bit "puzzled" why the Harmony stories are breaking the news ATM- I actually thought, we were already aware. @puca.bsky.social definitely didn't disappoint with the tracking and analysis of certain AIS tracks in the Barent Sea.

No radiation measured in Norway after Putin's nuclear-powered Burevestnik missile allegedly flew 14,000 km over the Arctic last Tuesday ☢️ 🚀 ⚛️

A couple more P-8's, 15 more F-35's, what's next in line?

The race to the Arctic has official been declared open?

F1 at COTA until 2034, seems like I still have a little time to buy tickets. 2026 rule changes are going to be a first interesting change

Google Earth has updated its images of Novaya Zemlya, the Arctic archipelago where Russia’s nuclear weapon designers are conducting tests of their latest inventions. The Barents Observer zooms in 📡 and highlight the facilities at Pankovo test site for the Burevestnik ⚛️ ☢️ missile.

@puca.bsky.social maybe something you've been waiting for, for quite a while now

Existing NOTAMs for Novaya Zemlya will be renewed at 2100 tonight. Most vessels associated with the Burevestnik test program have departed Matochkin Shar to take up positions off east & west coasts again. Teriberka & Mars currently at Pankovo. Uncertain, but possible test attempt in coming days.

*waits patiently*

❗️🇩🇰Denmark is considering purchasing P-8 Poseidon maritime patrol aircraft from the 🇺🇸United States to monitor the Arctic, in particular the waters around Greenland, - Danish Defense Minister Troels Lund Poulsen said.

Something different but also important today. After Bloomberg's illegitimate attempt to copyright strike the documentary over a 3sec clip- used under fair use btw- it's finally back online. They thankfully got bloomberg'ed for that. Everyone, go watch! youtu.be/1H3xQaf7BFI?...

Well that's one mystery solved the easy way

The U.S Navy has provided Naval News with the first official view of a P-8 Poseidon carrying an AGM-158C Long Range Anti-Ship Missile (LRASM). This comes after spotters caught glimpses of a P-8A airborne with an LRASM under its wing www.navalnews.com/naval-news/2...

HUGE improvements are coming!

Burevestnik related activity likely continues today, with the ships supporting the activity in test positions (exclude the one in Matochkin Shar). Sentinel-2 caught a contrail over the northern island, prob a support aircraft. Wind today has been from the south. FR24 picture for reference.

Saab has been contracted by the Swedish Defence Materiel Administration (FMV) to develop a new Large Uncrewed Undersea Vehicle (LUUV), the company stated. ukdefencejournal.org.uk/?p=61763

My apologies for the slight delay on my end @puca.bsky.social. Based on temporal offset between Sentinel-2 bands B04/B02 (1.005sec), the two POSS helicopter were flying at around 106KTS*. Kamov Ka-27 (or civilian version Ka-32) have a cruise speed of around 111KTS. * ±5kts
