Zothecula writes: Until the 1960s, Japan's three I-400-class subs were the largest submarines ever built. They were so large, in fact, that they could each carry and launch three Aichi M6A Seiran amphibious aircraft. The idea was that the submarines could stealthily bring the planes to within striking distance of US coastal cities, where they could then take off and conduct bombing runs. Now, for the first time since it was scuttled at the end of World War II, one of the sunken subs' aircraft hangars has been photographed. The M6A on display at the Air and Space Museum's Udvar-Hazy Center is worth seeing, if you get a chance.

The Japanese strategy of using their subs as highly ineffective aircraft carriers is one of the reasons they lost the war. While they were wasting their efforts on that, the American's were using their subs as commerce raiders, devastating the Japanese economy ... and the Japanese failed to stop that because they never developed effective anti-sub warfare. They should have consulted with their German allies, who could have told them a lot about the effective anti-sub tactics used against them in the Atlantic.

In the beginning, Barbarossa was launched with the assumption that the Soviet Union would collapse quickly. This did not happen, for various military, economic and political reasons.
Its easy to tell why it happened: HItler got distracted. Hitler pulled resources from the drive on Moscow and diverted them to the attack in the Caucasus for the oil fields. Had he continued the drive on Moscow they would have more than likely made it before winter, Stalin would have had to abandon the city, and most Soviet resistance would have collapsed. HIs insistance on personally controlling the war cost him the war and eventually his life.
I always found it interesting that, in the waning months of the war, many in the German high command clung to the hope that they would ally with the Americans and fight the Russians. Reading histories with 1st hand accounts and personal war diaries of the Wehrmacht can really change how you look at the war and really humanizes them.

It would be impossible to overstress the tenacity with which the Japanese clung to their prepared positions (in the Buna area). Ordinary grenades, gun, and mortar fire were completely ineffective. There were many instances where dugouts were grenaded inside, covered with gasoline and burned, and then sealed with dirt and sand, only to yield--two or three days later—Japanese, who came out fighting. One souvenir hunter, entering a dugout that had been sealed for 4 days, was chased out by a Japanese officer armed with a sword.
There were also numerous cases (I believe they were first encountered starting around Tarawa) where Japanese soldiers would kill themselves almost at the first sight of an American, blowing themselves up with grenades with a loaded rifle sitting next to them, not even trying to engage them. And don't forget, especially in the early days of the war, the officers usually got the soldiers drunk before banzai attacks too.

Why? Subs can lauch anti-ship missiles out of their torpedo tubes. They have vertical launchers for cruise missiles for land bombardment. A German firm is even developing sub-launched anti-air missiles similar to Sidewinders in capabilities. Aircraft carriers these days are more defensive weapons designed to protect fleets than they are offensive weapons, while subs are excellent offensive weapons.

If I had to guess, the trade-offs are disastrous---as evidenced by the fact that the US has zero in service.
Every square inch of hull adds 400+ lb of pressure at typical test depths. That is the physical constraint that every "feature" must be weighed against. Things that take up a lot of space get very expensive very quickly.

True, but one tactic that the Germans didn't realize was we were reading their codes and thus able to better intercept U-Boots and wolf packs. I'm not sure if Japan had developed sonar to the point it could detect submerged submarines; although radar could detect them while surfaced, which was their normal mode of operation, but then that also warns the submarine you are there before you detect them. Finally, the Allies pretty much controlled the seas in the Atlantic and thus could conduct ASW without much concern that they would get into surface battles; Japan did not have that luxury and was trying to fight naval battles that took ships that could be used for ASW away from that role. Not disagreeing with you but the two theaters were different enough that many of the things that work din one might not in the other.
