Navweaps has an analysis of the IJN torps in surface action. On average they manged a hot rate of a bit less than half what they intended.
And one problem of the 1.1" was that is was cramped. All four barrels were next to each other, so the crew was standing shoulder to shoulder. The 40mm quad had two pairs of barrels widely separated.
PS: Tassafaronga was the perfect example of a night battle gone right for the IJN but it wasn't the rule. Far from it.
Rick, you're confused as usual, and not worthy of discussion.
You should learn the difference between potential or intended use and actual historical use. I gather that you think the B-2 could not deliver a nuke to Russia because it was never done, it's at best a "whimsical" idea. That's not the level of intellect I want to discuss with.
We both know what would happen if I point out all your failure to think clearly in detail. I would waste time, it would clog the thread, you wouldn't learn anything, and even if I point out 20 mistakes of yours in a row you would declare victory if I had a single real minor inaccuracy. I would treat you as a worthy partner for discussion if you hadn't taught me otherwise.
At the 2nd Battle of Guadalcanal the USS South Dakota presented 680' of target to the enemy. I don't know if Washington was attacked with torpedoes or not, but let's say she was, so that's 1,360 feet of target at about 27kt. The IJN scored zero hits on what must have been dozens of launches. I didn't see a handy number of shots, so let's say 0 for 50. Against a fleet of let's say 12 USN battleships, 10 cruisers and 30 destroyers, that something in the order of maybe 300 IJN torpedo launches (plus maybe 150 more after reloads, so call it 450 fired in total) versus something like 24,500 feet of hull target. The number of torpedoed fired is roughly 10 times more than against the battleships at 2nd Guadalcanal, the total hull size of the fleet is roughly 18 times longer.
Glenn, some supplementary information at:
From WoWs -- I don't know where they got their information from.
NEW MEXICO turning circle radius 640 m. Rudder shift Time 17.4 sec. Pretty much the "Standard Type" pre-WW2 US BB.
IOWA turning circle radius 920 m. Rudder shift Time 22.5 sec. Just for fun
FUSO turning circle radius 740 m. Rudder shift time 17.1 sec.
MUTSU turning circle Radius 750 m. Rudder shift time 13.7 sec.
KONGO turning circle Radius 770 m. Rudder shift time 17.2 sec.
FUBUKI Turning circle radius 640 m. Rudder shift time 3.8 sec. Just to compare a DD with a BB.
So it appears the US BB have a little tighter turn and about to almost the same rudder shift time as the IJN BB. Both would be important in turning toward or away from a torpedo attack. Also, the US BB secondary guns have a range of about 18K yds, which is the range the IJN spotted US CA's at Savo and within the 48-50kn speed range of the Type 93 at that distance.
From what I could find, two US CA's were sunk by surface and SS torpedoes only; the Northampton and Indianapolis, the former by three and the later by two(in a non-battle setting). It could be anybodies guess on how many Type 93's a US Standard Type BB could take before sinking or forced to retire. At least four? AFAIK, the IJN sunk the damaged and abandon, derelict USS Hornet with four Type 93, a ship about 10K less in weight, and less torpedo protection than a a pre-war BB.
So some problems with the pre-war IJN plan: Actually "whittling down" by torpedo carrying surface ships by luring the USN during a night attack? That would require the USN to act as the IJN expected them too, a mental error that in part led to the Midway debacle. After the IJN fired their torpedoes, the surviving USN DD would need to get within about 6K yds to fire theirs. So, torpedo wise, we can never really know. I guess the closes would be to game it several times and see what occurs. But the introduction of the torpedo bomber made the torpedo ship obsolete when CV were involved.
This is not to take away from the power of the Type 93, or more importantly, the skill of the sailors using them, but the scenario which they depending on sinking the USN did not occur, nor could it appear.
