Ya know. I've served my country, proved my metal, and passed the test. But something about the open sea has always put me on edge. And photos like this one are a prime example of the reason for my 'edginess'. I 've also seen the wartime footage of the entire bow section of a Battleship (can't remember which) completely disappearing under a swell!! Something the size of a Battleship just ....what did you call it? "Taking it wet"?
Brother, I'd be 'taking it wet' as well!!..I'd be wetting my pantaloons!

Tread.

Maybe that's why I always stayed in the AIR! :-)

Halfyank,

The seasickness passes with time - its the floating around for days among the sharks, after your ship sicks, that kept me out of the Navy. That and my claustropobia. I prefer to see the sun and stars several times a day!!!

I'm not sure wheather you were trying to state it or not but the Lexington and Saratoga were built on cruisier hulls. The donor hulls were started and all most completed before the treaty that limited the number of capital ships. We can probably thank that treaty for having the carriers in the first place. Once we had them they soon proved their worth, ay least to the right people.

Howdy Tread, many people think the Ise with her flite deck are ugly and clumsy looking ships. But I like um ! With there pagota superstructure and the high flite deck I think there awesome ! This is one I wish to see in 1/350 scale, I would drop everything to build it!

Cheers Amigo,
Garry

Yeah, I fully agree Garry. I was very dissappointed when I found out there was no offering of the Ise Class ships in 1/350th. I too really like the ' variant'! Which is really the reason I posted the photo in the first place.

Greetings Tread, Speeking of variants! Did you know that the Japanese also rebuilt one of there heavy cruisers to a hybrid carrier just like they did with the Ise class? Yep they altered the cruiser Mogami. Added a flite deck simler to that of the Ise. I built the model of it, a 1/700 Tamiya kit. cool ship! I got pic's of it in my gallery. I cant remember if that was the only cruiser they transformed, but I beleave it is. And no dang gum it, they dont make it in a larger scale!

Regards,

Garry

I've been away for a while and have just spent the last hour reading this thread. 2 comments I wouold like to add.

1. Depth detection with sonar during WWII. The sonar radiated from the destroyer is a cone shape. As the destroyer got closer to the sub, the sub moved out of the cone and the sonar return was lost. Simple geometry then allowed a calculation of depth. I can't recall which way it went but last second changes to depth settings account for many mangled fingers/hands/arms. The Hedgehog system consisted of a number of forward firing mortars and the shells only detonated on hitting the target thus allowing sonar contact to remain longer with the target. The combination of the "cone" and the interference caused by detonating depth charges is the reason escort vessels worked in pairs. One vessel could stand off to one side and maintain contact with the target.

2. BBs moving sideways when firing broadsides. When I was a kid I used to enjoy going through my great uncles library of National Geographic magazines (every volume from 1922? to when he died in 1975). I was intrigued by the wartime issues and one volume had an aerial photo of NJ or the Mo firing a broadside - the 2 things that stuck in my mind from the caption were (a) that she moved about 20 feet sideways and (b) the photo capture d all the shells in flight and the centre barrels fired slightly after the outer ones.

know what Sub commander's did to address this situation around the time of WW II. But, If a Sub Commander found himself in a position where a torpedo, while it was sitting in the torpedo room, began to (I think it's called) 'hot-run'...what's the first thing a Sub Commnader would do. Or, more accurately. What would be his very first Command?


Great thread. I should have read it earlier. I've been a bubblehead for 26 years so I might be able to answer a question or two however, a lot of the questions you raise get into areas I won't discuss (that's one reason they call us the "Silent Service").
As far as the hot run goes, there are two problems...1. the weapon is spewing toxic gas into a closed room. WWII boats had no gas masks or EAB's (emergency breathong masks) so time was critical. 2 The biggest problem is that the 600-700 lbs of explosives in the warhead could detonate. Obviously you want to get the weapon shut down. Several of our submarines were hit and sank from a torpedo they had fired (it circled back after leaving the tube) consequently a device was added to the weapon which would shut the engine down and inert the warhead if the weapon turned x number of degrees after leaving the tube. The solution to the hot run would be to order a course change to the boat, once the sub had turned the requisite number of degrees, the torpedo -which is in the boat and therefore also turning -would shut down.

Mogami was the only cruiser so converted. Her Division of 4 Heavy Cruisers had been assigned to bombard Midway Island after the Japanese carrier force had been reduced to so much junk. As I remember reading, the orders to execute were late arriving from Admiral Yamamoto aboard the Battleship Yamato, and the mission was cancelled so that the ships would be out of aircraft range of Midway and the American carriers by daylight. All 4 were ordered to make a simultaneous turn, but for some reason, Mogami didn't copy the signal light message, and got rammed in her rear end, by her sister ship, the Mikuma. Mikuma, which suffered even worse damage than her sister, was picked off the next day---helped along by the crash of a Dauntless dive bomber on top of one of her rear turrets. The engine room ventillators sucked down avgas fumes from the wreck and KABOOM!

HA!!!!!! Someone got it dead on!! You are absolutely correct Cob, the Sub Commander would immediately order the boat's helmsman to turn either 90 or180 degrees! (depending upon the particular Commander) Thereby 'confusing' the torpedo and allowing it to shut down.
Good on ya!

Tread.

Gee. I had a bunch more Sub questions, but now there may be a 'ringer' out there to answer 'em all! :-)

OH......before I forget. Tonight on the History Channel (whatever happened to the' History Channel Updates' our very good member Kencelot used to post? ), they are airing the Submarine Special 'Blind Man's Bluff'. A superb show.........WATCH IT!

Tread.

BTW, they will be focusing on the declassified Soviet 'cable taps' that the Sub's Halibut, Seawolf, and Parche participated in. You guys remember the Halibut right? The old klunker that was part of the Regulus missle system? Had the huge opening in her hull to fire the missles? The 'opening was what they used for the 'cable tapping' operation.

P.S. Don't worry about me being a ringer, the people on this site always manage to come up with the right answer to just about any question.
