Fluid dynamics don't matter, right?

We were doing an exercise with scare charges (1/4 stick of dynamite) to simulate explosions.

Well, one of the trainers didn't throw it far enough from the ship and rattled the ship enough to have a vavle leave a high pressure bottle and a break a few other minor things in the immediate area. No hull breach though.

Torpedoes, meanwhile, contain about 6500 quarter sticks of dynamite.

So, ~6500 malfunctioning valves and ~6500x few other broken minor things?
Perhaps they can offset that by letting sailors bring more of their personal effects as long as they count as "minor things" and place it in those places :P

No, the valve still functioned. It just took all the threads holding it in to the bottle with it when it took the rocket sled to the bilge.

Edit: 6500 valves would be almost all of them.

All those words made sense. Separately.

Do you want to understand what it all means?

Now that I read it after having eaten some food, I actually managed to get the picture.
Of both, the previous - valve leaving the bottle - and the - projectile into the bilge.

Okay, I had to look up "bilge" for that.

Although I don't remember there being threads to hold down a valve wherever I saw them, I'd rather not have to visit a ship again, just to make sure.

It depends on the valve. Think of scuba tanks. Those valves are screwed in.

A real cope hull needs to create a bubble curtain around the ship (in addition to the metal cage). Bubble curtains greatly help to attenuate shockwaves in water.

Welcom back torpedo nets.

What about massive baggies of Nickelodeon Gak strapped to the hull to slow the torpedos down?

So, everyone here aware that modern torpedos create air bubbles under the ship to break the keel.

It's not about physics, it's about what you can convince some failson procurement officer in the Pentagon to pay an eye watering amount of money on
