Red Swordfish

[NARSES2]

My mind was working on those rocket spears that penetrated U-boat hulls. Swordfish carried 8 of them (I think) and even if they didn't penetrate, they would cause a deafening CLANGGGGG!!! and totally befuddle the poor tank crew.

You now have me thinking about the amount of kinetic energy those "spears" hit a sub with ? Never thought about it before, but as said I'm now thinking about it
