As far as the torpedo maintaining orientation, the massive computing power and inertial guidance system keeps the torpedo in the most efficient attitude. There is a lot of talk about the ADCAP’s digital computers well, before the digital computers many of the functions were analog when necessary.
The torpedo’s range safeties. Anything within this volume that is detected if the torpedo is searching for a target will be classified as ‘friendly’! Outside the these limits are treated as an enemy.

I would imagine so but, either way its inertial guidance would keep it aligned properly.

Thank you for the details.

I got the photo from a book entitled, “Underwater Missile System” back in the 1970s. I came across the book once at the Stanford University library.

If you are trying to break the keel of a large carrier, focusing the energy offers greater assurance that the massive network that forms the keel will be broken. Breaking the keel of the HMAS Torrens, an 2,700 ton destroyer escort and breaking the keel of a ship that displaces more than 30,000 tons are two different things.

Going back to Kursk and the mysterious round hole. This hole was said to have been cause by a shaped charge and is in the SIDE of the sub (not in its bottom).
Here’s an explanation: http://www.bellona.no/bellona.org/english_import_area/international/russia/navy/northern_fleet/incidents/kursk/18142 (story of 2 holes of 1 x 0.7 m each)
