**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**
Thread 🧵

#Ukrainian strike on #Russian Navy base at Sevastopol in Crimea appears to have damaged, possibly seriously (TBC), the submarine support ship Kommuna (ref ) hisutton.com/Russian-Navy-K…
Kommuna, ship cutaway
Video
Kommuna gets a degree of sympathy because she is an ancient and beautiful ship, 112 years old(!).

But objectively she is a legitimate target and provides Russian navy with valuable capabilities. She often participates in submarine trials and can conduct seabed warfare Image

***UPDATE***

First images of Australia’s new 3D printed extra-large autonomous underwater vehicle (XLAUV), the Ghost Shark. 🧵 Image
This is the previous graphic shared by manufacturer Andruil, when the deal for 3 vehicles was announced. See hisutton.com/Australian-Nav…
Image
The design has a square cross-section which contrasts with the rounded form of the previous artworks. This maximizes volume for its given outer dimensions

Crucially, it can still likely fit inside a standard shipping container, an advantage over larger types like the Boeing Orca used by U.S. NavyImage

Thread 🧵
2 years ago today, Ukraine hit the Russian Black Sea Fleet flagship Moskva with two Neptune missiles.

At the time it seemed like a spectacular event. But the real story of how Ukraine turned the situation in the Black Sea around was only beginning. #Moskvahisutton.com/Russian-Navy-M…
The missiles hit amidships, likely detonating a magazine of the AK630 anti-aircraft guns. Image

***UPDATE***

Reports that Transnistria (part of Moldova) may request annexation by Russia.

May trigger action from Moldova with #Ukraine help

#Russia realistically unable to intervene, in part because Ukraine has sunk so many of its landing ships in past 2 years

**HOT TAKE**

Thread 🧵

Reports that Turkey will allow some #NATO warships through the Bosporus into the Black Sea.

This raises several questions. Still digesting it but sharing some thoughts below. Caveats apply.
#RussianUkrainianWar Image
Firstly, if USNavy or Royal Navy deploy ships, I would expect only ‘defensive’ ships to be sent. Most likely coast guard and/or mine hunters. The reasons are obvious. Image
