It's a dud - again! - Page 3

I was between 1200 and 1500 yards away, using the compass to draw a 1200 circle. I normally attack at 1000. But I knew these guys could see me a bit easier, so I drew a 1200 and still didn't get to the edge of it. I was too scared, lol. :p

How many duds should I expect to get? This seemed a little high to me. Heck, if 7/10 are going to be duds every time I might as well surface the dang boat and pop off deck gun shots, I might even hit something then!

Welcome to realism, in the real show, I find it amazing that a bunch of skippers didn't take their sidearms to the torpedo folks at the BuOrd.

Simply amazing...

That was a great post Capn Sinky.....

I seem to remember somewhere that the depth problem was caused by the BuOrd testing the depths somewhere, Panama? New England? and the conditions in the Pacific being different, causing the torps to run deep.

Atmospherics or something like that....wish I could remember where I read that.

In some cases sub commanders had their torp crews field strip each torp before firing so they could verify that the torps inner mechanics were functioning. Course when they reported this to the Ord Dept they basically said "well that eliminates the torp, so you must be an idiot." Navy Ord Dept officials were not the most liked individuals at parties. There were several recorded instances of Jap freighters making it to their destinations with unexploded torps sticking out of the hull. Nothing ticks a sub commander off more than to risk life and limb to sneak in undetected, fire a full spread of fish, escape back to port and be called an idiot by a know nothing desk jocky.

Some of this is in TM, I think, you would want to talk to Duci about it, but I think he modeled in, or moded someone else's mod, that modeled in the torp problems to be more realistic.

I'm waiting for 1.5 to show up, and then running some with TMO and seeing. As for me, I was getting a bit tired of all my torps working, really ahistorical.

Sorry for the triple posts, but after being here for like seven years, I'm excited to make it to 1000 posts.

They did most of their testing on the Mk 14 at Newport Torpedo Station. The depth issues had a little to do with the location (not as much as the mag exploder though) The biggest issue for the depth was with the placement of the depth sensor and the weight of the warhead they tested with was different then the actual warhead used in combat.

Looked up some of the reasons in Robert Gannon's "Hellions of the Deep: The Development of American Torpedoes in World War II"

He lists, on Pages 85-6 a few different reasons for the depth problem, including:

1. Problems with prewar testing diagonostics and methods.

2. The depth control system axis layout.

3. An uncompensated increase in the exposive size.

4. Depth sensors only tested in still water, not while the torp was moving.

5. Lack of compenstation for combat conditions.

6. various malfunctions of "mechanical gadgets"

7. crew mistakes.

I'm sure that I read something somewhere about the differences in sea pressure between Newport and the South Pacific. That might be crazy, I'm still pretty sure that I read it somewhere.
