I thought one of the funnier things about the Zumwalt is that everyone is getting a hard on over the BrahMos supersonic anti-ship missile and how that's the demise of the US Navy. The Zumwalt has 80 VLS tubes, and in those they can 4 pack anti-air, anti-missile missiles that are capable of intercepting supersonic missiles and aircraft that can maneuver.
That is true, plus storm guns and escorting Burkes.
The best play for a direct fire gunship, is armor, lots of it, where this ship would go, there is nothing to hide behind or solid ground under their feet, you must bring everything you need with you, armor provides cover in the open.
Zumwalt falls far short in survivability. and it`s the BB replacement.
BrahMos is not an armor piercing round. Nobody`s ever claimed it was because it can`t pierce armor. Decap maybe, not the citadel.
