No sweat. You know more about it than I, but I suspect we may be talking about two different torps here. The KBT torp, for use w/the P-3, is a modern airborne torpedo, grey in color, that sometimes launches singly, and sometimes in pairs (unpredictable); it comes out so incredibly fast it's hard to make out details except for the color. I can tell you it points straight down, not at an angle. It does fly (fast!) in a forward arc in front of the aircraft - nose down - to the water. The KBT torp's recommended launch height is indeed 1,500 feet (also described as the standard patrol altitude for the P-3), which I don't understand; that's a terrifically high altitude at which to launch a torpedo, you'd think you'd launch it while you're down low following your last MAD pass. For this thing to take off at the speed it does after dropping from 1500, it must be rocket-assisted.
PS - I know those jets - they're Canberras - I've got them in the hangar.
