atomicthumbs posted:so what the gently caress was with the Sheridan? who thought that missilegun was a good idea? The Sheridan was originally designated to use a 76mm gun, but eventually the order got passed down that the tank had to be able to penetrate 150mm of armor. There were other considerations like mounting a 105mm/90mm/76mm with a separate ENTAC, TOW, or Polecat launcher, but the latter two still had development time left, and XM551 was being held up enough as it was. They decided that the 152mm launcher being developed for the Shillelagh would do. The Sheridan was just full of messed up stories. The Shillelagh's guidance system could suffer interference from sunlight and its own smoke plume. The latter was solved with an improved propellant, and I'm not sure how they overcame the former. I'm sure they did though, as having sunlight behind the infrared command link probably lent to its abysmal early performances. At one point, the Army was so scared of the thing that they wouldn't let more than one round of ammunition be inside the fighting compartment at a time during testing. The Sheridan is my favorite tank as there are just loads of stories about it that exemplify all of the worst parts of the MIC at the time, but also because it performed surprisingly adequately in its Vietnam missions.

Communist Zombie posted:So assuming the Luftwaffe won the Battle of Britain what would be the real effects of it? Like Britain moves closer to a peace deal, shipping avoids the channel, etc? Im also talking about allied reactions to what they think Germany can do; it doesnt matter if Sealion is a farce if the generals think its a possibility and react accordingly. hogmartin posted:Same question but with U-boats. Churchill is quoted as saying "The only thing that really scared me during the War was the U-Boat menace". Was it actually an existential "lose another convoy and we have to start negotiating with Germany" threat? What does that look like? It's hard to say. On the one hand, Britain was highly dependent on imports even for just basic needs, their vast industrial prowess was useless without raw materials to fuel it, and civilian trade generally isn't too willing to risk destruction for their paycheck, so any disruption to shipping was a Huge Deal even if it didn't completely cut Britain off. Being a relatively strong democracy meant that Britain's position was somewhat more prone to change than other countries, and since they were in the war to defend British interests and allies rather than Britain itself, it was possible popular opinion might decide to bow out if things looked bad rather than putting their own homes and families on the line for the sake of continental Europe. There's a reason German admirals in the First World War thought unrestricted U-boat warfare was worth risking America joining the war. On top of that, the British knew very well that their army wasn't that great by the standards of mainland Europe even before Dunkirk left them in quite a poor situation, and the Wehrmacht looked pretty drat scary after curbstomping the French so much more easily and quickly than anyone had expected. If the Royal Navy, the mightiest fleet in the world and a particular point of British military pride, could be contained or defanged to the point where German surface ships could freely sail the seas, it would be an incredible blow to national morale. If the Germans could have seized air superiority and used it to press the attack against the Royal Navy or British shipping, it's possible that political support for war in Britain would dry up and lead to a negotiated peace recognizing German dominance on the continent. On the other hand, the estimates of German admirals in WWI of their ability to attack shipping turned out to be overly optimistic, and I think estimates of how quickly Britain would have fallen under blockade tend to be exaggerated. In addition, we know now that Germany didn't have nearly as much ability to threaten the British Isles as either side thought at the time; if Germany managed to botch up a big operation and reveal their shortcomings, it'd boost British morale rather than hurt it. And the biggest question mark of all was Winston Churchill, who was practically made of confidence and morale despite his many faults. As long as he can hold on to meaningful political power, even talking about a negotiated peace would go pretty far into Gay Black Churchill territory, since there was absolutely no way he was going to sign an unfavorable peace with Hitler. Could the opposition have mustered the political support and leverage needed to force him out at a time like that? If not, then it's all pointless, because he would certainly have insisted on Britain fighting to the death no matter how bad things looked.

Or if you meant from a business point of view, businessmen were as patriotic as anyone else (and could also see a victorious Germany dominating Europe would be the dominant commercial/industrial power in pretty short order, in any case).

Prior to the debut of the modern convoy system in late WWI, U-boats didn't just sink ships, they kept more ships off the seas for fear of U-boat attack. It never fully stopped trade, even during the hottest days of unrestricted U-boat warfare, but it did have an additional impact Britain could ill afford. By cutting the heavy pre-convoy losses down to a much more reasonable number and granting a feeling of safety to sailors, the British were able to keep the trade coming. If something were to turn the situation against merchant shipping in WWII and reduce the Royal Navy's ability to protect and escort trade, it'd start putting off shipping pretty quickly. Even if German planes weren't that effective at sinking ships, civilian crews aren't very happy about sitting there and getting bombed.

That doesn't seem terribly likely, though, even in the rather alien-space-bats case that the Luftwaffe has total command of the skies permanently, given the short range of German fighters. They couldn't even reach Liverpool so interdicting the middle of the Atlantic? Not so much.

I've a question: how effective was allied intelligence regarding Japan during World War 2? I know certain Japanese naval ciphers had been broken in the runup to Midway, but I'm guessing that the Allies didn't have a open book via sigint with the Japanese - and if they didn;t have that, they didn't have much, at least in Japan itself. I ask because I was thinking about the strategic bombing raids against Japan. If the Allies had known "yeah, the Japanese still have planes - no pilots or fuel though" would they have bothered?

IIRC, they had a very effective SIGINT on the Japanese. They assassinated Yamamoto from a radio intercept, as an example.

I remember a story to the effect that their intelligence was so good that when they used a lack of water at an island as cover as part of an operation to establish where attacks would be focused, not only did they not get caught at the time but the subsequent invasion force was found to be carrying water purifiers with them after they were defeated. I think that might've been this thread, even.

I think that might've been this thread, even. I believe that was the setup for Midway. To confirm that they had cracked the code, they had Midway radio that they were low on water. Intercepts then included notes that Midway was low on water, which confirmed that they had the code name for Midway correct and that's where the Japanese were heading.

I'm not quite sure where the idea that the Luftwaffe so totally inept against naval came from - they almost certainly sank more ships than did any other air force or navy over the course of the war. Granted, a fair amount of that was due to their having more targets than anyone else, but reading this thread it seems like people are under the impression that they just sharted themselves and flew home to clean up whenever the time came to attack a ship. That being said, the bigger issue, in view of the Battle of the Atlantic at least, would've been their keeping Allied ASW aircraft out of the air. Without the assortment of fat dumb slow war winning Coastal Command planes: flying about finding and killing U-boats, the Battle of the Atlantic gets really, really, really hairy. Couple that with the Luftwaffe being able to operate relatively unmolested in the Western Approaches, etc and so on.

I should have specified "by air" – the U-boats sank far more ships than did anyone else – but the Luftwaffe sank more ships from the air than anyone else did, and that by a fair margin ( I can give exact numbers when I get home later this week). The US is only other country anywhere close. remember, the vast, vast majority of ships sunk during the war were merchant steamers at sea, not battleships in harbor. In any case as I said earlier, clearly the biggest factor in the number of ships they sunk was simple opportunity. I'm not suggesting that the Germans were some kind of wizards at Airborne anti-shipping – but they also weren't completely inept. Also if you really want to see some poo poo look at how many ships Germany sank with all weapons during the war, then compare it to the total Allied merchant fleet, Particularly after American industry got ramped up. American shipbuilding was something loving else during that era.

AND the light aluminum armor combined with the caseless ammo scattered around to make the tank very prone to catastrophic explosions and fires when hit by RPGs or mines. It ended up being the tank from the Sherman "Ronson" myths. Funny enough, I went to the USAHEC in Pennsylvania and they had a recreated Vietnam artillery firebase on the trail. The base of the watchtower was lined with Sheridan ammo crates.

Conversely, the M48 could take hits, meaning people would come back with some of the crew wounded or dead, and talk about how terrible it went.

Problem: Where do we improve the armor on bombers? Easy answer: Look at the ones that came back. The places that are shot up are the places that took damage and need to be armored. Better answer: Look at the ones that came back. The places where they have no damage are the places where damage killed the ones that didn't come back. http://nowiknow.com/seeing-is-disbelieving/

My point wasn't that stukas are the solution, but that it doesn't take armor piercing bombs and naval torpedoes to kill merchantmen. History is a good guide here. Condors killed their fare share of surface shipping during the war, and in many of those cases they were attacking escorted convoys. poo poo got to the point that they were strapping hurricanes to catapults as one shot interceptors where the pilot would just try to ditch near a friendly boat. Having escorts nearby can be a problem, but it doesn't mean that no attack happens or that the convoy gets through intact. You don't have to make it impossible for warships to operate and your attacking aircraft don't have to be unmolested, they just have to be effective enough to cause enough damage. Does this require Germany to do some things differently? Of course. Building a lot more condors or maybe a naval bomber version of the Ju88 is probably a requirement if you're trying to cut off England from resupply by sea. The fact that you don't destroy the RN, however, doesn't mean that land based aircraft can't wreak havoc on your shipping.

Risking a can of worms in this thread but I'm curious, the loathing against Tank Destroyers in this thread, or TD chat, is that more the US doctrine of it or against the things themselves? Thinking that you hear people ragging on the idea of them, but less so individual models. Was curious as I was reading some stuff about the SU-85 and SU-100 and they don't get mentioned when it comes to TDs.
