Another example of why this sort of testing is important - without pressing the "because nuclear" emotional button: In WWII, Germany's new "pride of the Third Reich" battleship, Bismark, had her main radar equipment disabled during her first major battle. The cause? Concussion from firing her own guns. You'd think they'd have designed for and tested that, but...
(Your friendly, local WWII naval warfare enthusiast - or a few well-chosen YouTube contributors - can cite many, many more cases where shock/concussion damage was a painful or fatal surprise for the crew of a ship. Especially in battle, damage to important ship systems or structures tends to cascade rapidly out of control.)
