As you are well aware, the program has been defunded by the House Armed Services Committee. The House Seapower Subcommittee Chairman, Mr. Taylor (D-MS-04), has publicly stated that is opposition to the program is based on his concern for future cost growth. The Congressional Budget Office (CBO) has estimated that the first two ships of class will cost $5.1B each, rather than the $3.15B each predicted by the Department of the Navy (DON).

The CBO analysis is wrong. CBO estimated the Zumwalt first ship cost by scaling up the costs for the preceding Arleigh Burke Class Destroyer. CBO failed, by their own admission, to address the fact that the comparison of vessels is obviated by the designed in Zumwalt improvements that specifically reduce the cost growth drivers experienced by Arleigh Burke. These improvements include: fabrication in sections indoors, fixed price contracts that lock in 43% of the ship cost making, beginning construction with 85% of the detailed design complete rather than 20% of Arleigh Burke, Arleigh Burke is much more densely packed making the price per ton an invalid comparison, and the fact that the computer models used in the 1970’s designed Arleigh Burke were not able to handle the ship necessitating restarting the design.

The last five Chief of Naval Operations from; Admiral Boorda (1994) through Admiral Roughhead (2008) have testified before the Congress to the need for the capabilities of the Zumwalt. The requirements have been validated by the Joint Requirement Oversight Council (JROC), and they have not changed. The Congress has responded by appropriating $11B in RDT&E monies to develop the technologies that will reduce manning and provide the DON with the enabling technologies for the “family of ships” for the entire 21st century fleet.

It seems only two will ever be built. This was the headline article on Fox news last night at around 1:00AM. Such an advancement in ship technology that it is sad to see it being scrapped.

Not entirely true. The SSGN's, while truly an asset to the USN, cannot pound the shore as the Zumwalts are intended to. It's been mentioned in this thread previously, but I want to reiterate that these ships are absolutely Technology Demonstrators.

I equate this ship as the surface Navy's version of Seawolf. In each case, the Navy set out to build the best aggressor possible. In the Seawolf's case, it was built to hunt, track, and destroy Soviet SSBN's and any SSN's that pose a risk to our own fleet or the Seawolf's mission. To that end, the Seawolf was envisioned as the no-holds-barred, pull out all the stops SSN. 8 tubes? Sure. New reactor design? Sure. Larger beam? Sure, just make sure power goes up to account for it, can't have this thing be slow, can we? In the end, the Navy got a heck of a submarine, possibly the finest SSN built to date. However, the cost for those bells and whistles raised eyebrows in Congress as the Soviet Union disintegrated.

In many ways, the DDX program, now the DDG-1000, is the "surface Seawolf." First off, it's big. 14,500 tons is really more of a cruiser than a destroyer. Quiet, efficient, electric propulsion in a vessel this size? That's new to the USN. Capability for railguns to be added when fully developed? New. Composite "stealth" deckhouse? New to the USN. Zonal power distribution? New to the USN in this configuration. Automated zoned fire-fighting systems and piping rupture isolation valves? New to the USN. Advanced Gun System firing the Long-Range Land Attack Projectile 100 nm onto shore at a rate of 10 per minute? New. Peripheral VLS for ship survivability in combat? New to the USN. Dual band RADAR, automated replenishment and tumblehome hull? All new.

This ship was envisioned as the "Ultimate Destroyer" (nevermind that it's the size of a cruiser. However, what Congress sees is that the Navy is spending $3.2 Billion for a DDG-1000 and buying DDG-51 Flight IIA for $1.1 Billion. The Arleigh Burkes are still very capable ships, so why is a Zumwalt 3 times better?

What I predict is that the Zumwalt Class ends at 2-3 ships (the 3rd ship was just defunded) and the technologies developed for this class find their way into DDG-51 Flight III's and CG(N)-X and DDG-????. To go back to the Seawolf analogy, the Virginia was built as a "Seawolf Lite." With the Zumwalt, we see the Seawolf. What we don't see on the horizon right now is the Zumwalt Lite. I do, however, expect it to show up on the horizon any time now.

Actually, the Navy doesn't see battleships as any sort of 'threat' or 'replacement' for modern ships. Bringing the Iowas back into service would cost a LOT of money, even compared to the Zumwalts. The entire communications suite would have to be rebuilt, and there would have to be substantial upgrades to habitability, and that's just the inexpensive stuff. We'd have to build factories and reverse-engineer tooling to build spare parts. We'd also have to build up stocks of 16" ammunition. While we're doing that, we can pull in the surviving battleship crewmen and set them up as instructors to train new crews...very few systems on an Iowa are anything like the rest of the Navy.

Once we've spent a few billion on the three ships (take your pick on which one wouldn't be pulled back...Missouri for historical reasons, or Iowa because of damage to turret II), and a few billion on a supply and support system for them, what do we have? We have 3 ships, which means *at most* two of them deployed at any one time, that can strike targets up to 40,000 yards away (22.7 miles) with 1,900lb projectiles containing 153lbs of explosive. Don't forget to take a few miles (between 2 and 10, depending on conditions) off that range because the ship is going to stand out in deeper water.

Compare the numbers with any precision-guided munition or surface-to-surface missile, and you'll start to see why the Navy isn't in any hurry to bring the battleships back. The march of technology has done to the battleships what it did to the "Line-of-battle" ships that came before them.

Back to what happened to DDX/DD-1000/Zumwalt...too much new crap at one time. In a system as complex as a modern warship, it's pure idiocy to try to simultaneously develop new propulsion systems, power systems, weapons, hull forms, and electronics. Problems feed on themselves, deadlines slip, and costs spiral. The smart money would have been to deploy the 'new' systems on the last few Burkes (the electronics and power distribution systems, for example), shake most of the bugs out of those, then add the AGS (which could have been getting a better shore-side test in the meantime), then add the now-proven electronics and weapons into the new hull...but our current 'transformation-at-all-costs' cult wanted every bell and whistle at once...and the Navy is paying for it in spades. A closing prediction: If you think the Z's were bad, wait until Chapter 2 of this story hits with the F-35/JSF program.

From Defense News 22 July 2008:

The once-vaunted Zumwalt-class DDG 1000 advanced destroyer program - projected in the late 1990s to produce 32 new ships and subsequently downscaled to a seven-ship class - will instead turn out only two ships, according to highly-placed sources in the Pentagon and on Capitol Hill


I'm in full agreement that the destroyer fleet is getting a bit old, but the Burkes are still very solid platforms. The "DDG 1000" / Zumwalt class wouldn't be a viable 'replacement' for the Burkes (never mind the Perrys), simply due to cost.

As much as I'd like to see railguns deployed, I'm a lot more "bummed" by the general trends that I see in current Navy programs. Rewind just a few years to the Virginia class SSNs. Supposedly, they were going to be almost as good as the Seawolf class, but represent a huge decrease in cost. Depending on how you do the cost-accounting, they came out a lot less capable, and at least as expensive, possibly more so...and a decade later to boot. Then we get the DDG-1000 / Zumwalt. The less said about this, the better it will be for my blood pressure. Currently in the pipeline, we have the JSF...and I'll bet any reasonable amount of cash that, as time goes on, we'll find that the JSF's costs were under-estimated when the thing was pitched to Congress, and that its technical problems were minimized. This will lead to the same scenario we just saw played out with DDG-1000, in my opinion. Then there's the likely king of money sinks...the Navy's CGX program, that's still in the paper stages, and already smothering itself in bad planning. The Navy can't decide whether to build an actual cruiser (multipurpose warship capable of semi-autonomous operations in the classic style), a theater ballistic-missile defense platform, or (the most likely to be selected and least likely to work) a hybrid of the two. Add in the fact that Congress is pushing to make nuclear power a requirement, and things get really "amusing", thanks to the initial costs of nuclear power, and the political problems of basing / porting nuclear powered ships.

Even if one puts cost aside, let's not forget that the DDG-1000 is truly massive at 14,500 tons. That's cruiser displacement there. Hardly the tool you'd use to replace a FFG.

Congress is past the point of "pushing for" nuclear power, they've made it a mandate that all "Capital Ships" shall be. No ifs and or buts. Hey, REpresentative Taylor even wants to nuke power the latest Burkes with the A1B reactor designed for the USS Gerald R Ford, despite the fact that he's been told it's a physical impossibility due to size constraints.
