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

Bayonet underwater drone (UUV) with tracks can crawl out of the sea. Quite a useful capability…

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

Thread 🧵

**NAVY DECOY SHIPS AND DECEPTION**

Always an interesting topic, we all know about inflatable fake tanks, but it can happen with ships too.

Firstly, fake ships before D-Day:

During WW2 the royal Navy converted some fleet tenders to resemble battleships and a carrier, with the idea being to deceive German Luftwaffe reconnaissance flights.
Before/ after (might be exact same ship, but you get the idea)

The old battleship HMS Centurion was also remodeled to appear as the newer ship HMS
Anson

Before, after:

2 years ago this month in Russo-Ukraine war in Black Sea, JULY 2022

Short thread 🧵 from

Prelude: June 30 Russia withdraws from Snake Island. The island is strategically located near Ukrainian coast and shipping lanes

#OSINT hisutton.com/Timeline-2022-…

Snake island had been subject to air strikes but Ukraine had also started using MLRS from barges at sea and it was in range of new 155mm artillery being delivered by West, especially the French Caesar system

In July 2022, faced with threat of Ukraine’s Neptune anti-ship missiles, and western supplies Harpoons (notably Denmark), Russian navy largely withdraw from western side of northern Black Sea. This is a significant change in the balance.

I don't normally post about aircraft, but here are 5 awesome and usual loadouts from the Cold War which really interest me from a design perspective.

In descending order of awesomeness

5. A-5 Vigilante US Navy bomber with nuclear bomb up backside

4. English Electric Lightning. Awesome fighter, could carry ferry tanks in the overwing position. Hard to find photos of this, but it could also carry twin SNEB rocket pods above each with, with fuel tanks behind them (!).

3. Ilyushin Il-102, which lost out to the now-famous Su-25 FROGFOOT. Aside from rad lines and rear-facing aft cockpit, check out the tail gun!

**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…

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

***UPDATE***

First images of Australia’s new 3D printed extra-large autonomous underwater vehicle (XLAUV), the Ghost Shark. 🧵

This is the previous graphic shared by manufacturer Andruil, when the deal for 3 vehicles was announced. See hisutton.com/Australian-Nav…

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. Navy
