Hit Manila. Those 20+ subs are far more deadly then the battleships at Pearl That would be true if the US subs had decent reliable torpedo's. It is amazing that the US had just about the best subs in the world in Dec '41 but the worst fish imaginable. The Mark 14 was slow, had poor range, didn't always leave the tube and both its methods of detonation (contact primer and magnetic proximity) were very unreliable. It has been widely quoted that taking allt hings into account, the mark 14 up until the middle of '43 had a failure rate of aroudn 80%... And it was also slow and poorly ranged into the bargain, especially when compared to IJN fish. The older S-boats, which stemmed from a WWI design in theory were slow, obsolete and limited range and in fact were scheduled for replacement by the end of '42 (although hostilities and other demands kept a lot in service until the end of '43). However they used older torpedos (again dating from a WWI design) rather than the newer, more complex and ludicrously expensive mark 14, which only had a contact detonator but was far more reliable. quote:
This question had been subject to heated debate within the US Navy before the war. The single-CV TF was probably optimal for the 1941-42 period, while offence dominated defence. (After Eastern Solomons, it was claimed that the 10-15 nm separation between the two carriers preserved the Saratoga unhurt while the Enterprise was hit hard.) On the other hand, at Coral Sea, the US carriers initially operated in a single formation. The fast CVTF was a pre-war development, designed for scouting, raiding, and anti-raider operations. It consisted theoretically of a carrier, two to four escorting heavy cruisers, a CLAA serving as DD squadron leader, and a destroyer squadron That is also true, but it was a largely theoretical debate and had actually not had much practice/training in fleet exercises, certainly nothing before the late 30's and only because of teh increasingly military threat from Japan, and also the acrimonious debates about the Orange Plan, defence of the Philipines, and coudl carriers somehow make everything easier/workable. Midway was the first time two US carriers had operated together in one TF (16, E & H), it had never ever been tried before and everyone was worried signals and commuinicatinos would be a nightmare and cause lots of accidents/problems - as it was several planes did join the wrong landing circuits which lead to delays (and a few even touching down on the wrong flightdeck) and recognition was generally poor all roudn (but not as awful as the Coral Sea). At the Guadacanal landings, E Solomons and Santa Cruz the US carrier groups all operated independatnly of each other, funnily enough the IJN also went back to operating smaller carrier groups either in pairs or else single carriers rather than a big concentration of force (not putting all your eggs in one basket I guess) The US fast carrier TF though at least according to pre-war thinking was still primarily for recce/search and possibly hunting down the odd merchant raider (a naval species which had flourished primiarly in WWI, and despite a few odd successes in 41-42 its day had really come and gone). Also the SBD dive bombers were trained to hit shore targets rather than enemy ships, it was only in the late 30's that this was re-focused to be primarily on enemy shipping although the training (trying to drop a practice bomb on a stationary buoy or else a slowly-towed raft marked with smoke flares) left a lot to be desired. Certainly though nobody in the US Admiralty seriously considered using aircraft to compeltely knock out the enemys battlefleet singlehanded (disable a few big battlewagons to be finished off in a surface shooting match a la Bismark perhaps, or else disable the oppositions carriers/recce planes), unlike the IJ who having learned the lessons at Taranto perhaps better than anyone else and despite some opposition from the 'big gun/decisive fleet battle' voices were streets ahead of the US in Dec '41, both in terms of training as well as deployment and end-use. It was only when the smoke was rising from the wreckage of PH did the US Admiralty finally tear up its long-cherished battleplans and look more closely at the idea of the fast carrier TF and whehter or not it could meet the IJ on equal terms - as it so happened it most definitely could not, but it was the first step in the right direction
