I'm not holding my breath regarding the weapon actually being used on an operational warship. we have heard lots of claims about the development of weapon systems that are 'game changers' but when push comes to shove there is no shove..
IF this ship did become operational then what type of battle group would protect it? I should imagine any submarine in the same ocean will hear the thing when that pop gun makes a noise and once heard it is in a whole heap of doo doos unless it has the ability to defend itself.
The Zumwalt class is allegedly using
state of the art weaponry which can possibly do whatever this system might be able to achieve.
