Feasibility: Ship reactive armour?

[Joe C-P]

There are two active torpedo defenses being considered by the USN. Active is always preferred to passive, because you'd rather knock out or dodge the weapon than try to absorb the blow.

1. Deployed nets that catch and slow or redirect the torpedo.

2. 20mm guns with super-cavitating shells.

Between passive and active, there are also the Nixie towed devices that can redirect sound- and wake-tracking torpedos.

I remember hearing that someone has invented a new plastic that will actually re connect itself together if it is cut.  I know this won't help stop a torpedo or missile hit, but would it help with the repairs afterwards?

With the power of a modern torpedo, i would say no. Once the ships back is broken, holes in the hull are the slightest of problems...

while i was under training to go to sea in the royal navy we were taught that if a hole has a diameter over 12 inches wide then it is almost imposable to stop it leaking as over two tones of water per hour could be coming through ( thats over 6 time the pressure of a fire hose
