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.
Silence is a state of mime.
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.
Post may contain irony: discontinue use if experiencing mood swings, nausea or elevated blood pressure.
One thing I don't understand about modern naval warfare: Couldn't you just send 50 cruise missiles in skimming across the wavetops and take a ship like this out? Or a few ballistic missiles raining down from above at hypersonic speeds? Can these ships really defend against an attack like that?
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.

Well, Mr. Smartypants - click my second link. Current research says nothing HAS changed. Righting arms. What is that, you ask? Well - what it means is, a Zumwalt putting to sea from Hampton Roads will have hell just GETTING TO SEA. Zumwalts can't cruise the Arctic circle in the winter months. In fact, they can't cruise the central Atlantic in hurricane season. Tumblehome is inherently unstable in heavy seas. It doesn't matter how much technology has changed, a high center of mass remains a high center of mass.
Now, when the bright boys invent anti-gravity, a high center of mass may not mean anything. Until then, Zumwalt is a death trap.
Read, and learn. There is a career available for you in marine architecture, if you can grasp basic physics.

Long story short - the Zumwalt is a fair weather sailor, and it won't be worth a shit in the real world.
It won't be worth a shit in the real world for a far more serious reason, that the enemies it'll be facing is Somali pirates, suicidal zealots in zodiac dinghies, and random insurgents in third-world arenas. None of the high-tech toys or cost are justified for this, all it'll do is make the repair bill more expensive when, say, a small fibreglass boat from Yemen blows a hole in the side of one big enough to drive a truck through. It's another example of a US military branch aiming for the most expensive toy they can build rather than something that's fit for purpose (cough)F35(cough).
There are names for sizes of ships. There is no such thing a super-sized destroyer. It's called a light cruiser. I guess Congress funded a destroyer, but they get a cruiser instead.
