It depends

Magnetic for lone ships or convoy identified ships, in calm water, high aob angles

Impact for attack convoys at night, running at surface, (when you can´t identify well the target and you don´t know the keel depth), or for finish damaged ships

I set pistol at 3.5m (2.5m for small ships) for early part of war until '43.

Kill C2's 99% of the time with one shot aimed right where forward bridge-house meets deck (where fuel and engine room bulkhead is).

Trouble with magnetic is you have to know depth of target. I'm not sure how to calc this. I.E., if cargo ship ID manual shows 4.7m depth, do I set it at that depth or 1m lower?


;) ew

4.7 keel depth...set torp to run at 5.7-6.2 (or as close to that as you can get)...CH

I would think that the large vacuum bubble at the point of explosion would do alot of damage as well by allowing the ship to flex back down under it's own weight before the water rushes back in.

Or would the water fill that void before the ship came back down?

When a warhead is detonated at close range beneath a ship, the steam void initially lifts the ship upwards from the middle. This tends to weaken the ship's keel. After the steam void has reached its maximum volume the surrounding water pressure will collapse it. The ship then falls into the void, still supported on its ends. The keel will then break under the ship's own weight. The compression of the steam void will raise the temperature and the bubble will oscillate a few times. The ship may be destroyed during the subsequent oscillations if it manages to survive the first.
