WASHINGTON, Aug. 14 (UPI) -- The "Navy after next" envisioned by speakers at a conference Wednesday could bear little resemblance to today's fleet.
Discussions of "transformational technology" held sway at the Naval-Industry Research and Development Conference as officers and senior officials described the sort of force the United States hopes to field in the 2020 timeframe. Such technologies would impact well beyond current operations, shifting the very fundamentals of how the Navy does its job.

This is very nice, conceptually. The author discusses the various efficiencies in energy, space, and maintenance required. What he doesn't mention is reliability and survivability. These aren't cruise ships.
There was a case a few years ago when a destroyer, as I recall, was brought to a full dead in the water halt for one hour because a zero had been entered in the wrong place in the engine control computer screen by a stressed ensign. It crashed the system. If that had been a combat situation it would have been tragic.
I hope they'll build a few at a time so they can get more of the bugs out. It probably is the way to go in the long run.

Never has been, and never will be........a substitute for raw tons under sail.
By the title I feared a strategic departure from that axiom, but it appears the author exaggerated a bit.

There is one problem with this scenario making it all electric leaves it totally at the mercy of EMP weapons( more than we already are). It would be nice if they could design a gaussian cage type ship( ie only defense against EMP) that would work.

but it appears the author exaggerated a bit. No he didn't. (except I can't comment on the virus stuff).
To: weikel
There is one problem with this scenario You're exactly right - and that one problem is that there are a heck of a lot more than one.
To: nevergiveup
I bet the other technical problems could be worked out eventually. The EMP vunerability to the point where it not only blinds the radar( and satellite uplinks, communications etc) but sinks the ship is a real problem though.

I'll be a little less circumspect this time, EMP ain't the most pressing problem being solved.

"
An all-electric design replaces the current maze of steam and hydraulic systems with electric cables and motors throughout a ship, Sullivan said. Doing so allows a vessel to spread out its essential systems and become more damage-resistant, he pointed out."Maybe, maybe not. An atomic bomb detonated high in the stratosphere and 500 miles away wiped out the electric utility in Hawaii in the 1950s. An all-electric ship would go dead in the water after something like that.

Gee I guess the combat ship designers must have never heard of them thar EMP thingies or dah Hawaiin street lamps. Perhaps one of us should send them an email or something. We might also want to send a warning to those ignoramous research groups trying to figure out how to mount ultra-high power EM weapons on our ships. They may not know how much damage those things can do.</sarcasm>
To: Willie Green
There's also the serious issue of creating shipborne power grids capable of handling currents as high as 13,000 volts on the next-generation aircraft carrier, he said. Aren't there any technically-savvy editors left anywhere?

'Ceptin there ha'int no shieldin' from thet thar EMP-type stuff. Thet thar stuff don't behave nuttin' liken unto the 'lecric noise that comes from a hair dryer or an arc welder. It goes plumb through any ol' shieldin' they is.
To: Hank Rearden
LOL yeah I didn't notice that for non engineer types voltage is not a unit of current its a unit of whats called "potential diffrence". This dude may not know what he is talking about.
