I just bought Silent Victory and LtCmdr Fluckey's book off Amazon, so I expect to be very educated on the subject before SH4 comes out

. I read in the Time-Life WWII series book called War Under the Pacific that BuOrd DID do multiple tests, but they didn't test with the real detonators. As don1read said, the handmaid fish were 10,000 dollars; BuOrd was not willing to expend that amount of money on destroying perfectly "good" torps. So during their tests, BuOrd used a warhead filled with water instead of the TNT mixture used in war-time. As it turned out, the TNT was significantly heavier than the water, thus the fish sank about 11 feet deeper.
Also, DeepSix, you mention the Mark 11? I have not heard of this... please enlighten me. And I know in '43 (?) they came out with another "super-weopon," the Mark 18. Was this just a the same thing as a Mark 14, but with a more powerful charge, and without the Mk 6 detonator?
