I my previous life I was a Torpedoman - not the "Fire One!" type, but one who disassembled them and made repairs
. This type of footage is always pretty humbling...
Rather than impact the hull
as they did in the early days, modern torpedoes like this one are designed to explode several feet beneath the target. This uses the water
column to distribute the force.
This was most likely a MK 48 torpedo - we sell them to most friendly countries. Although it's been a few years and could be perhaps a Marconi unit or another UK-sourced fish
Whatever it was - it worked eh?
