US NAVY MK13 Air dropped torpedo
Early design required the low speed low altitude drop and ran up to a max speed of 33 - 34 knots (subject to who you quote) with a maximum range of 6300 yards.
Later generations of the MK13 were designed to be high speed high altitude dropped up to 2400 feet and up to 410 mph
In it's final incarnation the MK 13 weighed in at 2200 lbs +- and had a HE warhead of 600 pounds of Torpex.
"It would be nice to have the "later" production MK13, then you wouldn't need to be low and slow."

I am searching for my manuals on German torpedo's, but the air dropped had a model designation of FB5 Torpedo, if my memory serves.
Will try and post as soon as I find the manual.
