Arleigh Burkes aren’t stealthy at all by current standards. The Zumwalts have somewhere around 1/50th the RCS of a Burke, while being much larger in displacement. We try to reduce that with radar absorbing tiles and blankets all over the ship, but you can only do so much. But yeah, the Burkes actually deploy regularly and have purpose, while the Zumwalts have become a very expensive “proof of concept” for other future designs.
Stealth is overrated in aircraft and it is many times over overrated in ships. 1/50 of Burke is big enough to detect at any sufficient range with modern radar technology. Not to mention radar is not a single way to track assets of such sort.
ARB is proven. I’d say more but don’t need any visitors.
