How much energy would this take?

Post by Junghalli »

Does anyone know how much energy or destructive force (you can use joules or tons of TNT, I'll be happy with either one) it would it take to snap an Iowa class battleship in half?

Hit the keel in the right spot and she'd snap from hogging stresses, like any ship.

And ADCAP or two under the keel ought to suffice.

I might add that an ADCAP apparently has an explosive energy of about 544 kg of TNT, or 2.3 gigajoules.

Also there's an image sequence here showing a 28-year-old Australian destroyer being easily snapped in half by a single ADCAP, albeit under the keel to take advantage of the hogging stresses Degan mentioned. Maybe double digit gigajoules would be a safe bet for snapping an Iowa.
