  1. https://www.youtube.com/watch?v=oRlt1vbnXhQ Watch the part with John Mearsheimer. The AUKUS sub deal is about so much more than subs. Australia may also get a 1000+ mile range hypersonic missile. Mearsheimer is interesting for sure. He predicted the USSR would not make a conventional move because they knew a breakthrough was unlikely. After the Cold War, Soviet docs showed plans for massed nuke strikes at the outset of a war. Mearsheimer also predicted the 1991 Gulf War would be a cake walk for the US because of Iraq's 3rd World status, lack of mobile warfare ability, air inferiority, artillery inferiority, and bad defensive dispositions. Most others were saying it would be a bloodbath.
  2. 40+ years old but the only new thing I've seen in torpedo propulsion tech is hybrid. https://ntrl.ntis.gov/NTRL/dashboard/searchResults/titleDetail/ADA079034.xhtml
  3. Strategic ASW and Naval Strategy http://kashti.ir/files/ENBOOKS/pdf. Strattegic antisubmarine warfare & naval strategy.pdf Almost 40 years old but very interesting. Appendixes have much good info. Why was the Trident II missile given silo busting accuracy? The author speculates that increasing the threat to Soviet land based missiles would force the USSR to use more naval assets to protest SSBNs, preventing these assets from being used to interdict NATO SLOCs. Speculation about the size of the Typhoon class. Elsewhere I have read that they carried 16 SLBMs and 4 satellite launchers, 2 commo, 2 surveillance. They would stay underwater for a year, put the satellites up, send surveillance data and find any rebuilding activity in previously nuked countries. They would then nuke it bouncing whatever was being rebuilt on the rubble. This, and some other stuff I've read make it clear why the Seawolf class was limited to 3 vessels. The Seawolf's major sensor innovation, a large sonar array, would have its range cut by Soviet sub quieting and would therefore not be able to search for subs very much faster. Elsewhere I read that the Virginia was better at everything except ASW than the Seawolf. As Virginia was improved further it caught up to Seawolf in ASW as well. Also, the swim out torpedo tubes on the Seawolf would work for electric torpedoes but not so well for thermal torpedoes with toxic exhaust like the MK-48. 50 torpedo capacity would mostly mean more torpedoes in Davy Jones locker in a real war. Larger sub to carry 50 torpedoes meany higher cost or lower performance for the other capabilities. Exercises showed that USN subs had a 3:1 advantage over Soviet subs in getting off the first shot. Assuming all torpedoes hit meant a 3:1 kill ratio. If torpedoes miss, then the Soviets would be in much better shape given higher sub speeds, higher firepower, and better battle damage resistance. All those advantages were magnified in shallow water and under ice, exactly where the US would need to go to hunt Soviet SSBNs. Had the Cold War continued quiet Soviet subs would have made it too difficult for the US to hunt Soviet SSBNs and forced the US to find another way to protect SLOCs besides forcing the USSR to hold back its entire navy to protect SSBN bastions. Author assumes Soviet SSBNs could be tracked but US SSBNs could not be tracked. Today there is some controversy over whether Chinese SSBNs should be tracked in peacetime and threatened in war. Apparently they can be tracked. https://carnegietsinghua.org/2018/10/24/u.s.-anti-submarine-warfare-and-its-impact-pub-77495

  8. https://www.youtube.com/watch?v=5gbZi2YTxyc The MiG-23 is not as well known as some of the other MiG models. It is not as fast as the 25 or as cost-effective as the 21. The video linked above says that the 23's reputation was built by the early models and that the late models were much better. Little is ever reported about the PVO interceptor MiG-23P. It was the Spitfire to the Su-15's Hurricane although the Su-15 got all the "action" if shooting at airliners can be considered action. The MiG-23BN was an interim model before the MiG-27 ground attack model appeared. The MiG-27 was the Typhoon to the Su-17's Hurribomber. The MiG-23 was the top of the line model during its heyday although it was much reviled in the Western aviation press. It would have been very interesting to see what the USSR would have produced if they had not insisted upon better field performance than the MiG-21. A MiG-21 upsized to use the MiG-23 engine with a solid nose and MiG-23 style intakes would have been really cool. Some interesting facts: The cannon's muzzle velocity was only 670m/s. The nose probe was used to generate vortices to improve AoA performance in some models. The later models could set the wing sweep at any angle at least according to some sources. The R-23 missile design was chosen over cloning a Sparrow captured in Vietnam. The R-60 missile is the smallest air-to-air missile aside from some planes mounting Stingers.
  9. https://www.youtube.com/watch?v=bu0wPgZVkyw https://www.youtube.com/watch?v=38MnOxQokM4 Millennium7* has some videos on the F-35. If you have not seen his channel yet, it is excellent. He is an aero engineer and goes into actual depth with facts and stuff. He's like the anti-Blacktail anti-Matsimus YT channel.

  13. A little off topic but I have read that aircraft production stats in WW2 Germany were inflated because they counted aircraft destroyed at the factory and rebuilt twice. I forgot the source on that. Maybe someone else has knowledge of it. Adam Tooze is the source for this. The limiting factor on German WW2 armaments production was steel. They could not produce more ships, planes, tanks, shells, or machine tools without lowering production of one or more of the others. This is despite conquering the steel production of most of Europe. It seems like grossly incompetent management. I posted a video a few weeks ago that contains an analysis of German management of their piston aeroengines. TLDR: Gross incompetence on a staggering level. As for the Panther, does anyone have the source comparing the number of hoses and number of different diameters of hoses in a Panther engine vs a Sherman? I saw it on YT (forgot which vid) and it was staggering how much more complex the Panther was. I'm an older guy and most of the books we had access to back in the day were implicitly pro-German. Seeing the internet was like being the unfrozen caveman from Saturday Night Live. Even neanderthals like us Gen X'ers can see the facts and make good analysis now that we have the internet. I don't see why so many guys who grew up with the internet admire the German equipment.
