    Bash the F-35 thred.

    The A-10 doesn't really have that much armor. The pilot is indeed sitting in a big box: That is an inch to an inch of a half of titanium, which has similar thickness efficiency to RHA. There might be some armor protection for the engine nacelles too: Most of the rest of the vital systems are protected simply by being redundant; e.g. there are multiple hydraulic lines going to the same control, so it's harder to sever the line with a hit. The A-10 was supposed to have some survivability against other aircraft simply because it operated at low altitude. For a long time, air-to-air radars had difficulty tracking targets that were below the horizon, and ground-based radars had difficulty tracking targets near the horizon. Advances in signal processing have greatly reduced these blind spots, however, so the A-10 would have fared poorly against an enemy with actual air defenses and interceptors.
  2. I think Trump weakening US soft power institutions is a temporary phenomenon. The reason he's doing it isn't because he necessarily has some ideological opposition to soft power. For instance, the video that was shown to the North Korean leadership during the Singapore talks dangled the carrot of integrating North Korea into the world economy so they could enjoy the same legitimacy and prosperity that their neighbors do. The reason that Trump is at odds with US soft power institutions right now is that they are filled with people who hate his guts and want him gone. There's a reason I've joked about Trump opening gulags; the US government is full of people openly scheming to get rid of Trump. Their competence is doubtful, but not their intentions. Trump will do everything in his power to increase the importance of institutions that are loyal to him at the expense of institutions that try to undermine him. But this state of affairs cannot last forever. Either Trump will go away, and things like the State Department and various NGOs will resume some of their former importance, or Trump will prevail and large parts of the US government will be effectively restructured. Either way, things will change.

    Israeli AFVs

    I misunderstood Serge. I thought he was referring to the air circulation system for the engine radiator when in fact he was speculating that this doubles as an IR countermeasure.

    Israeli AFVs

    It's possible that's what they were going for, but it's possible to camouflage a vehicle from IR sensors quite well without any active cooling.

    Israeli AFVs

    It has to be. Any engine powerful enough to drive a modern tank needs lots of air; either air to run through the engine core of a gas turbine or air to cool the cylinders or radiator of a diesel. This is one major disadvantage of the engine-in-front design; there needs to be a set of big-ass holes somewhere to let the air in and out.
  7. "Hill to die on" suggests a Pyrrhic last stand, but they can't even accomplish that much.
  8. ESR and VIM/VAR steels are used pretty extensively in tanks. Aside from torsion bars, they make mighty fine gun tubes and they're a good choice for inner layers of armor because they have less tendency to spall. They are used outside of military applications, but in predictably expensive and demanding fields like biomedical and aerospace. The bolts of AR-15 rifles are made of Carpenter 158, which is an electroslag refined steel. But the use of these steels is confined to applications where performance to weight ratio is paramount. The process for making them is energy intensive and demanding, and this is reflected in the price. I doubt that any suspension that's competitive on a modern MBT will have much in common with civilian vehicle suspensions. I think, in general, this is part of what has driven the cost of new military technology so high. This isn't the 1940s and you can't make a tank engine by gluing five automobile engines together. Top-of-the-line military hardware has very production commonality with civilian products anymore, and that drives the prices up.

    Reviews of Movies I Haven't Seen

    Ant Man and the WASP This movie isn't anything groundbreaking, and honestly the anti-classist themes seem outdated. But it was a fun watch and I enjoyed it anyway. Ant Man and the WASP is basically a gender-inverted, Americanized My Fair Lady. It's a musical rom-com about a blue-blood, high society woman who falls for a pest exterminator. I think that, in this era of increasingly polarized American society, this sort of goofy love story is just the treat.

    European Union common defense thread

    And the EU countries clearly waste money that way too. But it's not so easy to quantify corruption. But if we look at actual combat readiness of units in Europe, I think that the picture becomes even more extreme. US units are probably not, on average, very ready for combat. But their European counterparts are much worse.
  11. If you're talking about a pure torsion bar system, then I guess. But no tank with torsion bar suspension has only torsion bars. They all have auxiliary damping systems, either friction-based or hydraulic. The advantage of hydropneumatic is that the damping action is built in, and requires no auxiliary system.
  12. Welcome to SH DIADES! Tank hulls are giant steel boxes. Torsion bars free rotate inside a hole in the hull on the swing arm end and anchor into the opposite side of the hull (ignoring rare exceptions like the T-64). Any tank with a hull rigid enough to withstand the rigors of combat is rigid enough to mount torsion bars. Hydropneumatic suspensions need to attach to the hull somewhere, and this is typically done with a small number of bolts that are not particularly spread out. So I don't think they're particularly lower stress than torsion bars. There's no magical additional cushioning that hydropneumatic suspensions give vs. torsion bars. They have significant additional built-in dampening, but as I noted above, this has some tradeoffs.

  14. Sadly, I don't have good sources on the more obscure Soviet rifle prototypes. I'm very curious if they made any counterbalanced designs that were something other than AK guts with a counterbalance mechanism stapled to it. This pistol design is essentially a counterbalanced blowback mechanism.
