Watch The Navy Drop Earthquake-Sized Bombs Off The Florida Coast

This is the first I've heard about this. Maybe some of you know about it.

The Independence class Littoral Combat Ship USS Jackson flexed its muscles off the Florida coast in a July trial.
Nothing says freedom quite like launching 10,000 pound bombs from a warship during a trial exercise. But in July 2016, the USS Jackson littoral combat ship did just that off the coast of Florida.

These trials demonstrate the operational survivability of new ships by exposing them to underwater shock. For the USS Jackson, this was the third and final test, which employed a 10,000-pound explosive charge to test its durability.
