The U.S. Navy’s new high tech destroyer has been sidelined for repairs after suffering a seawater leak in its propulsion system less than a month before its expected commissioning.

Cooling system? Bad seals on the shaft? Story isn't very clear.
Engineering casualty is a term that has been used for a long time. In naval jargon it is a bad thing.
Is this the civil war ironclad?
Probably because the Zumwalt has some kind of computer-controlled stability system that uses maneuvering thrusters to help steady the ship.
Pity. I wonder if they could be re-powered, but that would probably still push the TCO too high.
Obama told them they couldn’t use the Rubber seal because it’s made from Oil
I don't know but it's been used for decades.
“Engineering” is the naval term for a ship’s propulsion systems. It doesn’t refer to the engineering work that went into creating the ship’s design.
The Enterprise doesn't even hit the fleet until 2025 so Kirk will either be a flag officer or retired by then. Regardless, since he isn't a pilot then he can't command an aircraft carrier.
Am I the only one puzzled by the fact that this ship doesn’t seem to have an anchor? What will they do? Only go to ports where they can tie up to a pier?
Pity, another chance missed. Well, maybe he’ll still be a Flag, so we can at least have Admiral Kirk and the Enterprise together.
The ship itself does not leak; the seawater coolant for the propulsion system leaks.
Oops! CYA
Granted that that coolant system is the source of the leak that damaged the propulsion system, and it’s a system that isn’t expected to have leaks, but that does not invalidate my assertion that all ships leak.
It does have an anchor. It’s kept inboard. If you look closely at the bow, you can see flush-mounted ports where the anchor can exit the bow.
The Zumwalt’s anchor is highly automated and is designed to be operated by a single sailor. The capstands on the Zumwalt are below deck, so they cannot be seen by enemy radar. The entire system drops straight down so the anchor is dropped out of the bottom of the hull.
One would imagine that naval architecture has advanced a bit since then.
You might recall that the Northrop YB-49 suffered from stability issues. And yet today, we fly the B-2.
