Largest Destroyer Built For Navy Headed To Sea For Testing (ap.org)
An anonymous reader writes: The first Zumwalt-class destroyer, the USS Zumwalt, the largest ever built for the U.S. Navy, headed out to sea today. Departing from shipbuilder Bath Iron Works, the ship left to undergo sea trials. The AP reports: "The ship has electric propulsion, new radar and sonar, powerful missiles and guns, and a stealthy design to reduce its radar signature. Advanced automation will allow the warship to operate with a much smaller crew size than current destroyers. All of that innovation has led to construction delays and a growing price tag. The Zumwalt, the first of three ships in the class, will cost at least $4.4 billion."
To compare, NASA s 2011 budget was 18 billion. Compare this to one project for one branch of the military, not counting ongoing ops.

Admiral, are you prepared to fight a hundred duck-size destroyers or one destroyer-size duck?
If Slashdot were chemistry it would look like this:Cadaverine
It's 600 feet long, so it would only cost $3000 at Subway. Unless you add guac. Guac is extra.
Repurposing missiles as ship killers? You have heard the term "guided missile cruiser", haven't you? The first purpose built guided missile cruisers were put in service in the early 80s, and could sink ships at 10x the range the big guns on the New Jersey could hit. The Harpoon anti-ship missile went into service in the 70s.
Now I understand the big criticism of the Zumwalt is that it has limited anti-ship capability; but it's supposed to be a destroyer. Destroyers traditionally play mainly anti-submarine and anti-aircraft roles, and in the US Navy mount modest 5" guns for anti-ship use. The Zumwalt's gus are actually 6.1 inches and have considerably longer range -- if they work as advertised. The idea of making it more potent in the anti-ship role would fall into the F35 trap: building cost-is-no-objecdt, do-everything wonder-weapons.

First off, there are no hypersonic missiles and will not be for a good 5 or 6 years at least. Secondly, swarming with missiles is, indeed, one way to kill warships. Its exactly what the Soviets planned to do in order to prevent the US from reinforcing Europe in the event of a NATO/Warsaw Pact war before the end of the Cold War. However, the US is very, very, very good at fighting this sort of war. A Zumwalt has 80 VLS cells that can be packed with missiles (though these are meant for attacking, not defending on the Zumies, except when using the ESSM self defense missile (4 to a VLS cell)). However, the Burke class, which would accompany a Zum, each have 90+ VLS cells themselves and an excellent radar system. You'll probably need a minimum of 50 to 75 missiles to get a ship for each Burke defending the Zum. It starts getting really expensive. The US is really good at the hot missile on missile action: even against ballistic missiles. The best way to attack a Zum is with a sub. Defenses against subs are not nearly as good as against incoming missiles. There are NUMEROUS examples of even 'bitty' SSK subs sneaking up on even the big carriers.
Do you know why the road less traveled by is littered with the bones of the unwary?
Ships really are not good at killing other ships, planes and submarines are better. Ships are best to house huge artillery to bombard inland targets with, or as cargo/carrier vessels.

This "futuristic" hull design isn't anything new. The French did this already, long ago. They sold a small fleet of these "rollover" design ships to Russia. And, Russia lost the only engagement in which they participated to Japan.

The Arleigh Burke class has 1.5 times the righting arm that the Zumwalt does, up to about 50 degrees. From 50 to 90 degrees, the Burke has three times the righting arms. Right around 95 degrees of roll, the Zumwalt stops trying to right itself, and capsizes. The Burke continues to right itself all the way to 110 degrees - that is, when the ship is lying on it's side, with the mast underwater, it can still roll itself back upright.

Long story short - the Zumwalt is a fair weather sailor, and it won't be worth a shit in the real world.

The navy has been playing this game where it builds a large ship and call it something smaller, because Congress is willing to build small-sounding ships without checking to see that they're actually small. The Zumwalt, at 14.5k tons, is more than half again as big as Tico-class cruisers at 9.6k tons. "Oh my God, that new destroyer is expensive," say critics. Well, yeah, because by displacement it's really not a destroyer; it's a cruiser. Maybe even a heavy cruiser.
