Re: torpedoes

About radio guidance for torpedoes, yes, there is no way for this unless you deploy an aerial above surface. Anyway, here in Argentina somebody tried exactly this, radio guidance and (stranger yet) explosion engine propulsion, air admitted via a kind of snorkel, will look for pictures. It had a lar...

Re: Ships blowing up when the rolled over

Thanks for your replies, i believe Scharnhorst actually blew up underwater after he went down, perhaps there were still fires burning new the magazines? The powder has its own oxygen, so a sealed compartment that is subjected to great heat (such as compression by dept of water) could cause the powd...

Re: torpedoes

A triple tube mount doesn't take up much space and it's another string in the bow.

Re: Ships blowing up when the rolled over

As far as I understand things, it is not the shells that explode in a magazine explosion, but powder bags. A ship that capsizes has taken heavy damage and may have some fires aboard. These fires as well as red hot fragment can ignite these powder bags. With enough powder to fling many large caliber...

Maybe boiler explosions?

Re: Jammed rudders and damage to prop shafts

I was on a guided missile cruiser that experience a rudder failure back in the '70s. Luckily this wasn't in confined waters, unless you consider the Panama Canal to be such. The skipper was about to beach her to avoid damaging anything when the glitch cleared itself.

Re: US fleet sail before attack on Pearl harbour.

Interesting document covering US Army defenses on Oahu. I suspect there were probably more ground-based AA weapons than aboard the ships. https://www.armyupress.army.mil/Portals/7/educational-services/staff-rides/StaffRideHB_PearlHarbor.pdf B And the source, I suspect, for that document: http://www...

Re: US fleet sail before attack on Pearl harbour.

Alan Zimm's book on Pearl Harbor might interest you.

As for Halsey, the NKB was achingly aware that the USN carriers were "out there somewhere" and they patrolled accordingly. There wouldn't have been an ambush scenario.

Re: US fleet sail before attack on Pearl harbour.

Halsey was sent south to look for the carriers due to radio intercepts of messages from a destroyer unit normally associated with carrier plane guard duty. The intercept suggested they were around Johnston Island. It wasn't until after noon that the Army advised Com14th of the radar track Lockard an...

My guess is that they would not use the modified torpedoes but the standard ones.
There were a limited number of the Nagasaki-modified torpedoes, IIRC. The ones without the wooden fins were in good supply as they weren't offloaded before the fleet sailed.

Re: US fleet sail before attack on Pearl harbour.

"ships not fully manned"? I was assuming that if the fleet was at sea, the ships would not have a significant portion of their crews ashore like they were on Sunday morning of the attack on Pearl Harbor. You know that sailors weren't automatically granted overnight liberty, right? "Cinderella liber...

Re: US Battleships

Thanks for your replies, Looking at the weight of some of the US ships, its interesting to note that some of the more heavily armed ships 8x16" and 12 x14" ship were built around the 350000 ton mark long before the Treaty limits were imposed, but the RN apparently could not do so later on. 350,000 ...
