**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:

Image 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)

In descending order of awesomeness

Quick 🧵 on Turkey not allowing #Ukraine’s 2 new Sandown Class mine hunters to sail to Black Sea

Lots of emotion on here

Yet this is such a non-news, here’s why.. Image Turkey blocked them under the Montreux Convention, which governs shipping through the Bosporus between Med and Black Sea. So the ships cannot sail to Ukraine.

This was *not* a surprise. As far as I’ve been aware it was already a foregone conclusion

One year ago today the NordStream pipelines were attacked in the Baltic.

There are many theories. What many do not attempt to do is explain the systematic of presence of #Russian Navy ships, including a submersible mothership, in the vicinity beforehand

 There are many theories, some quite fanciful.

Russia has said the British did it, then later changed their mind and agreed with Sy Hersh that the Americans did. Even though you could drive an aircraft carrier through the gaps in that story (it’s nonsense)

Refined likely damage assessment: this is an ex-submarine

New photos of #Russian navy submarine hit by #Ukrainian cruise missiles in Sevastopol show damage is even worse than previous noted. Photos appear credible. Pressure hull has massive breaches

 Damage to rear section near propulsion space, as well as bow area, means basically no hull sections are likely salvageable. Implications are that internals are wrecked along most or whole length of submarine

Based on the Airbus satellite images shared by UK MoD, it appears that that #Russian Navy Pr.636.3 Improved-KILO class submarine was hit about here.

 This may be strategically significant both because Crimea is a route to reinforce Ru positions in southern Ukraine, and because Crimea itself is the jewel in itself

North Korea (DPRK) has shown off a massive new ‘underwater drone’. Several (4?) were paraded through Pyongyang.

It’s a lot like Russia’s Poseidon at first glance

I am on my phone and just seen it, so HOT TAKE caveats apply, but a 🧵

#OSINT New underwater torpedo drone Firstly, it *is* a lot like Poseidon ()

It’s similar size (likely smaller and shorter) and has a very similar stern arrangement with folding fins and a ‘pump jet’ (or at least shrouded screw)
