**NOT A TANk**
Here -> hisutton.com/Bayonet-Underw…

Bayonet underwater drone (UUV) with tracks can crawl out of the sea. Quite a useful capability… Submarine with tracks
A few other tracked submarines /UUVs to briefly mentions.

Firstly, in World War Two German engineers built a tracked midget sub. The idea was to launch /recover itself from a slipway rather than drive along the bottom of the seabed
During the Cold War, the #USNavy had the NR-1 spy sub which could drive along the bottom. Wheels not tracks though.
There were several reports of strange tracks on the seabed in Sweden /Norway during the Cold War.

Culprit never proven (although certain Russian diving vehicles are plausible)
See hisutton.com/Russian_Tracke…

And hisutton.com/Seliger.html
There have also been several uncrewed crawlers. Meet the Soviet MTK 200 for “scientific research”
And various civilian ones for heavy engineering
But the new ones from Bayonet are much more modern

***BREAKING***

Reported attack by #Russian maritime drone on Zatoka Bridge, Ukraine, Feb 10, 2023

This is significant. Thread 1 /8
#OSINT Attack by maritime drone
2 /8
Video of the bridge being attacked is being widely shared on social media. This appears credible.

What follows is a hot take, caveats apply

3 /8
Some reports say it was an "underwater drone". I think that actually it is an explosives laden uncrewed surface vessel (USV)

This is the same concept that #Ukraine used so effectively against Russia in late last year

Goodbye darkness my old friend...

First clear Sentinel 2 satellite images of #Russian Navy submarine bases in Arctic today since oct last year due to arctic winter. #OSINT

Identifying warships and submarines is difficult in this low resolution imagery, and the 'snow blindness' and cloud doesn't help. But the giant KIROV class battlecruiser Peter the Great stands out easily in Severomorsk Russian Navy

**OSINT**

Thread. A couple of days ago we at @navalnewscom noted increased #Russia naval movements, unusual enough to warrant reporting.

Today, kalibr cruise missile attacks.

This is not the 1st time this has happened. Some thoughts

1/5

navalnews.com/naval-news/202…
On December 22 we made a similar report, and then too it preceded major missile strikes

2/5

navalnews.com/naval-news/202…
Important: i am not suggesting that we predicted these strikes specifically. If you read the pieces you can see that. But we did observe the increased activity which, in hindsight, was likely at least in part related (simplified)
