Screenshot of Twitter post from Etienne Marcuz, full text below:
🇫🇷🚀☢️ French Ministry of Armed Forces just confirmed the successful launch of an M51.3 intercontinental ballistic missile from the SSBN Le Vigilant, confirming its return to the operational cycle after 3 years of maintenance.

This was the first operational launch of this new version of the missile from a SSBN.

For the occasion, @CalvaireDrach
 and I prepared an infographic showing how such a launch unfolds, from the transmission of the order to the impact of the reentry vehicle(s) — without their nuclear warheads — in the Atlantic Ocean, 4,700 km West of the launch area.

This infographic is based on the analysis of American documentation, which is very extensive on the subject. There may be slight differences between the French and American systems (M51 vs. Trident II D5), but the general principles described here are common to this type of missile. The major differences lie in the details — network meshing and encryption, number and type of vectored objects, bus maneuvering capability and accuracy, weapon energy and governmental control systems, etc. These are protected by the utmost secrecy.

I will soon publish a more detail article on this on Letstalkdeterrence.

Many thanks to @CalvaireDrach
 for the work — if you wish to reuse this diagram, please credit her🙏

The 300 meter pixels of the Sentinel-3 satellites are pretty useless for shipwatching but I've still always been curious what the limits are. Yesterday gave me a natural experiment with a cloudless ocean patch. The ship and its wake are indeed a faint smudge, unidentifiable without the AIS track.

They do seem quite concentrated over the main pipeline & cable arteries in this section of the Irish Sea - where Yantar lurked in 2024. This flight in particular seemed focused on one of the gas pipelines: bsky.app/profile/puca...

I'd be reluctant to say for sure as I haven't checked it systematically - I seem to be noticing them more, but it could simply be training. I note there was a very recent "desktop exercise" between UK & Ireland, simulating an attack on cables in the Irish Sea: www.irishtimes.com/ireland/2026...

One thing that has fascinated me about Kosvinsky Kamen since I first started gawking at it a while ago, are the apparent mining operations that take place around it. I have visions of miners accidentally knocking through to the command and control facilities.

And a closer view over North Dakota and the missile silos. Even though this is hours before - you can kinda see how a system primed to detect launches, could possibly interpret these as trails from ICBMs...
