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

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… navalnews.com/naval-news/202…

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

 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)

 The jet ski was apparently involved in the July 16 Sevastopol raid, not the July 18 Kerch Bridge attack. However, it *may* be the same type as in Kerch - see later.

 At face value the attack was unsuccessful. Of the 3 reported ‘maritime drones’ (USVs), at least one was destroyed, and the ship appears undamaged (or minimally damaged)

Many people are disappointed

So it looks like these boats “don’t work”
