Pure BS. Those ships have ultra redundancy including heavy state-of-the-art electrical shielding. Dead in the water my ass. If that was the case, there would have been full blown all hands on deck. 18's would have been scrambled from the nearest base or carrier. The CIC would not have been in his bunk sleeping. Tankers or any boat for that matter would have been lit up like a Christmas tree outside of 1000 yards. The fact is nobody was paying any attention.

What? Some super secret weapon that can not only incapacitate a US Destroyer but also its entire crew?

lol..OK.
