This is an absolute beauty and better than anything contemporary by a long shot. There are some concerns about the tumblehome hull (used for reduced Radar reflection). It seems the US navy wants double hulls for stability.

I'm seeing a lot of hype on this forum about Zumwalt that's probably unwarranted; so here are a few spoilers...

--Yes, it is very large; but it also lacks the launcher capacity of older types (partially made-up-for with the guns) and is primarily purposed for land-attack.

--It will lack the capability of older types regarding missile/air-defense because improvements in that area were originally intended for the long-canceled CG(X).

--While its signature is indeed reduced, it is not "stealth" in the sense that can't be seen. It will still be picked up on radar easily enough, it just won't show up as immediately different from smaller maritime traffic.

--It does feature vastly increased automation and electrical capacity, but this has come at a high cost that made the full program unpalatable in light of the fact that it is essentially orphaned technology for the time being (goes back to CG(X) cancellation).

--Due to its radical design/doctrine, there will almost certainly be major operational headaches over the next few years; some commentators will be grown-ups about the problems, others won't.

Not to say that this hasn't been a worthwhile program. Zumwalt will be a valuable asset for testing new technologies that will eventually find their way into the rest of the fleet and the next generation of surface-combatants, but it isn't an invisible super-ship.

DDG 1000 Costs Soar by $3 Billion

The cost for the Navy's new DDG 1000 destroyer have risen by $3 billion since 2009, raising the cost per ship by roughly $1 billion, according to a recent report by the Congressional Research Service. The total price for all three of the Navy's planned DDG 1000 destroyers — DDG 1000, DDG 1001 and DDG 1002 – was listed at $8.9 billion in the fiscal year 2009 budget, according to figures released by the CRS report. The cumulative projected price for the same three ships in fiscal year 2015 is now slated at $12 billion, according to the report. First envisioned in the 1990s, the DDG 1000 is a high-tech, multi- mission guided missile destroyer designed for land-attack and littoral missions, among other things. A large part of the costs are likely wrapped in many of the next-generation technologies engineered into the ship. The ship is built with a radar cross-section reducing tumblehome hull and an electric drive propulsion system. The first of three planned Zumwalt-class destroyers, the DDG 1000, was christened in April of this year. In April of 2009, General Dynamics Bath Iron Works was awarded a contract from the Navy to build three Zumwalt-class destroyers. DDG 1001 is already 75-percent complete and fabrication of DDG 1002 was slated to begin in April of this year, Navy officials said. The DDG 1000 is built with what's called dual-band sonar technology which uses both medium and high-frequency detection. Medium sonar frequency is engineered to detect ships and submarines, whereas high-frequency sonar adds the ability to avoid sea- mines, said Raytheon's Wade Knudson, DDG 1000 program manager.

Well, I predicted more headaches in this program besides costs...

Delivery of First 2 Zumwalt DDGs Delayed

...The Zumwalt (DDG 1000) had been scheduled to be delivered to the Navy this summer, but that has dropped back to November. Delivery of the second ship, Michael Monsoor (DDG 1001), production of which is about a year behind Zumwalt, has also been pushed back a few months in 2016, to November of that year...
I expect the investment will be worthwhile in the long run. Flight III Burke isn't going well either, so we'll just have to see which design works better in service. Don't be surprised if Zumwalt's machinery ends up in a more conventional hull at some point in the future.

US Navy takes possession of its largest ever destroyer



The US Navy took formal possession of its largest ever destroyer as the future USS Zumwalt (DDG 1000) changed hands from the Bath Iron Works shipyard in Maine. Billed as "the most technically complex and advanced warship the world has ever seen," the handover follows months of sea trials during which the first in its class, multi-mission land attack and littoral dominance warship was tested to certify its hull, mechanical, and electrical systems, propulsion, and anchor and mooring systems.

With its distinct tumblehome hull and composite superstructure, the Zumwalt is notable not only for its size, but also for its suite of advanced stealth features that reduce the ship's radar profile by a factor of 50 over current destroyer designs.

Carrying a crew of 130 and an air detachment of 28, the destroyer is armed with two 115 mm Advanced Gun Systems (AGS) firing rocket-powered precision Long-Range Land Attack Projectiles (LRLAP) with a range of 63 nm (72 mi/117 km), which is three times greater than current surface gunnery.

The Navy says this is the first US warship to incorporate the Integrated Power System (IPS), which is an all-electric system powered by gas turbines. This design was chosen not only for economy and survivability, but also in anticipation of future energy weapons.

Named after former Chief of Naval Operations Adm. Elmo R "Bud" Zumwalt Jr, construction of the US$4 billion Zumwalt began in 2009 and it was launched in 2014. The Navy says that it's designed to operate independently in forward areas to provide presence and deterrence, as well as operating with joint and combined expeditionary forces as a multi-mission Anti-Air Warfare, Anti-Submarine Warfare, and Anti-Surface Warfare unit.

The Zumwalt will now undergo crew certification before its formal commissioning in October in Baltimore, Maryland, after which it will sail to its homeport in San Diego, California.

Note that there were also only 3 Seawolf Class submarines built by the US. But it spawned a cheaper but more numerous version, the Virginia Class.

USS Seawolf



USS Virginia



At least visually, there's not much difference between the 2, the same may go with their capabilities.

Maybe the 3 USS Zumwalt Class destroyers will spawn also a cheaper but more numerous version. The capabilities might not be that far off either.
I see your point. the technology once established and industry around it matured, ships like these will be cheaper. Unless US giant political games get in the way.

USS Zumwalt Leaves Bath Iron Works


Note the fewer sailors at the flight deck of the ship, which illustrates the much reduced crewing of this ship.
