RFA Proteus working away in the Irish Sea again today.
Around this time last year, RFA Proteus was shadowing Yantar while it lingered over cables and vitally important gas interconnectors in the Irish Sea, in some not so subtle signalling.
(To be clear, I don't know where Yantar is right now...)

The film #AHouseOfDynamite ends before the bomb hits Chicago, where @bulletinatomic.bsky.social is based. They asked me to describe what it would happen to the Windy City, so I dropped 20 KT and 4 MT bombs using @wellerstein.bsky.social's Nuke Map. (Hint: it's bad.)

The Dutch navy has escorted the Russian 'research' vessel Yantar out of the Dutch Exclusive Economic Zone in the North Sea last Tuesday, the defence ministry said. A Dutch research vessel, HNLMS Snellius, was tasked with checking the state of seabed infrastructure in the areas where Yantar sailed.

Teriberka (& Sabetta) have departed Pankovo/Gribovaya Bay, possibly for the final time this year - first visit was early June.
Fwiw, it appears the last obvious instance of RF interference from Pankovo on Sentinel 1 SAR, was on the day of the test - October 21st.

My apologies - I hadn't had enough coffee!
RZK Constanta is actually in Belushya Guba - it left Severny on 28 October, same day Yauza arrived in Severny.
It is Teriberka & (possibly) Sabetta in Gribovaya Bay.
I say "possibly" as Sabetta seems more reluctant to use AIS.

If actual nuclear testing resumes, China is set to gain the most.
If any one of the "big three", US, Russia and China, tests, I think the other two will follow.
The US triggering a new era of live testing would be a mistake, regardless of which admin that makes such a stumble.
