Because despite that the Zumwalts growth margins are far higher then anything out there without designing something new.
Alot of the so called deadweight is from having overbuilt auxiliary gear. Like heavier power lines for electric weapons like railguns and lasers. Over strength hull to take the mounting of such. Over power generators and engines to run everything, with the fuel tankage to make it want range, which is 6000 to the Burkes 4k at 20 knots.
Also so the navy doesn't have to tear the ship apart to refit it like the Burkes.
Alot of the minor stuff that they figure might need to be done in the future, like what Ive listed, has done on day 1 at the yard.
Resulting in a hull that is extremely easy to upgrade.
As seen by the hypersonic install.
You literally can not do that to a Burke without losing something major, like a VLS farm.
Cause as design tge Burke only had a 5 percent payload increase from the Spraunces despite being 70 percent larger. Losing a gun and 2000 miles in range, for roughly 32 more cells in comparision.
