[Psalm 73]

"...the Ford-class carriers to make more than three times the electricity of legacy Nimitz-class carriers."

They need that power for the (dubious) electro-magnetic aircraft catapults versus the (more reliable) steam catapults on the Nimitz carriers.

[BobL]

“They need that power for the (dubious) electro-magnetic aircraft catapults versus the (more reliable) steam catapults on the Nimitz carriers.”

But steam causes Global Warming, so it makes sense to build ‘more sustainable’ carriers.
