    Zumwalt revisited?

    See the below story: with a change of command within USN, it is speculated that the Zumwalt class may be revitalized.

    Zumwalt Destroyer Supporters Hope For Revival | AVIATION WEEK
    Lots of speculation. I hope Zumwalt has a future, but I think probability is degraded as capabilities are degraded. We know SPY-4 radar has been cancelled, and we know the Senate Armed Services Comittee is trying to kill funding for further development of the railgun and the free electron laser (top of page 21 in their press release at the following link: http://armed-services.senate.gov/pre...%20Release.pdf ). Zumwalt has the increased capacity for generation of electric power that would be useful in an electric powered weapon system with high cyclic rate.

    If they fund to completion at least one operational DDG-1000, then the AGS and the MK 57 peripheral VLS will exist on that ship and I think that boost probability of those systems later existing on other future classes of ships. If they abort Zumwalt, then those systems may die with it.

    If BAE's AGS-lite (described in the article below) is included in the Arleigh Burke flight III DDGs, that may further reduce demand for Zumwalts.

    BAE Developing Smaller Version of AGS System For Arleigh Burke-Class Destroyers

    By Carlo Munoz

    Program officials at BAE Systems are looking to shrink down the company's naval gun system designed for the Navy's Zumwalt-class destroyer (DDG-1000) and install the smaller version of the weapon system on board the sea service's Arleigh Burke-class warships (DDG-51).

    The Advanced Gun System-Lite (AGS-Lite) will trim 50 percent of the original AGS design and maintain the same 74 nautical-mile range as its larger counterpart on the DDG-100, while firing the same 155mm round, according to John Perry, manager of business development for advanced systems.

    A smaller magazine capacity and slower rate of fire are the only real tradeoffs between the AGS-Lite and the larger AGS, Perry said in an April 7 briefing in Arlington, Va. The range of fire provided by both AGS systems dwarfs the 13 nautical mile range of the legacy Mk45 deck gun on the DDG-51 ships, he said.

    That 74 nautical mile range provided by the AGS-Lite system matches that of the Tomahawk cruise missile, Perry said. At that range, the new deck gun could provide vital ship-to-shore fire support and supplement Tomahawk strikes against targets inland.

    Currently, program officials have only tested the gun's range up to 60 nautical miles, but are well on track to hit the 74 nautical mile threshold, according to Perry.

    The AGS-Lite system also features an automated loading system below deck, which replaces the six-man team normally required to load the Mk45 gun, according to the BAE official.

    While no program of record has been established for the AGS-Lite by the Navy, Perry noted that the Navy's stated requirements for precision fire support, coupled with its decision to truncate the number of DDG-1000s in the fleet, validated the need for the AGS-Lite.

    The initial AGS was expected to be the main deck gun for the Navy's future fleet of Zumwalt-class destroyers. But after serious cost overruns, the sea service opted to cut its DDG-1000 buy to three ships and fill the remainder of that destroyer requirement with more Arleigh-Burke class boats.

    With that decision, it was clear that the current Mk 45 deck gun on board the DDG-51s would have to be replaced with a more advanced version, according to Perry.

    With millions already invested into the AGS for the DDG-1000, it made sense to simply leverage the lessons learned from the research, development and design work for that system, and move that into the Mk 45 replacement.

    BAE officials have already completed a successful ship integration study of the new deck gun for the DDG-51, Perry said. The results of that study showed the system to be compatible with the legacy destroyer, in terms of power load requirements, deck profile and below deck space, he said.

    That said, company officials are on pace to complete final system design and development in the near future, Perry added.

    wow.. I didn't know that the TLAM was that short range.. especally since that's my job in the Navy, a TLAM tech..... (we teach for ESWS, Enlisted Surface Warfare Specialists) that the range is 1000+ nautical miles..

    74 NM is in the ballpark for the range of some variants of the HARPOON missile, but not Thawk.

    Lets just say any update to the AB or even the Ticos that are retired are worthless if they cannot ship the entire S series of guided missles among others. They need to be on par with the rest as far as interceptors or they wont be worth the money that will be spent. The R&D part of an upgrade is pretty much done for them. To build a new style DDG is no doubt going to cost more in either case when this info is irrelivant to a new build.

    As far as the Toms go I have info from Hughes (original manufacturer) for the BGM-109 from the 1980's thats states anywhere from 250-1500 NM depending ofcoarse upon which of the three varients at that time was chosen. This ofcoarse is not updated information as we are now 20 years and more later and they are far more accurate and updated.

    Here is another story with some comparisons of the updated to be built AB's and the Zumwalt's.

    DDG-51 Restart Raises Questions | AVIATION WEEK
    By the time they get done gold plating DDG-51 for flight three, and redesigning it to carry the extra gold, its going to make DDG-1000 look like a bargain, except DDG-51 will never get the stealth treatment and will never be able to send 20 LRLAP per minute. ...like Seawolf and Virginia.

    Here are a couple of excerpts I found interesting...

    " ...industry radar experts and even Navy officials acknowledge the Raytheon dual-band radar being developed for the Zumwalt (and for the Ford-class carrers) would have been tweaked just as easily for BMD. They also say the Zumwalt has other attributes—such as a lightweight composite deckhouse and integrated hybrid-electric propulsion system—that would have compensated for the AMDR’s weight and appetite for power."

    "...Northrop Grumman is talking about using composites similar to those in the Zumwalt for its DDG-51 Flight III version. The company is teaming up with HII—the former Northrop Grumman shipbuilding unit building the DDG-1000 composite deckhouse as well as the DDG-51—for its AMDR bid."

    "...there is talk about developing a hybrid drive similar to the Zumwalt’s to provide more power for the AMDR in Flight III."

    Another follow on story that indicates that their may be a chance for follow on orders (if there is any cash to buy anymore).

    As a follow on to that... It might be good that they cancelled procurement of the S-band AN/SPY-4 for Zumwalt, if they are planning to later retrofit Zumwalt with the presumably more capable AMDR-S, when (and if) AMDR is funded through to production. But it remains to be seen how long AMDR may be delayed, if it survives the ongoing process of defense budget blood letting.

    It looks like AMDR-S and the RSC were the first priority, and maybe AN/SPY-3 X-band is good enough for the near term.

    From October, 26, 2009:
    https://www.fbo.gov/spg/DON/NAVSEA/N...0/listing.html
    The Naval Sea Systems Command (NAVSEA) intends to post a solicitation for up to three Technology Development Contracts for the Air and Missile Defense Radar (AMDR) S-band Radar and Radar Suite Controller. ... AMDR is envisioned as a radar suite designed to be scalable to accommodate current and future mission requirements for multiple platforms. AMDR will consist of an S-band radar (AMDR-S), an X-band radar (AMDR-X) and a Radar Suite Controller (RSC). The AMDR-S will provide volume search, tracking, Ballistic Missile Defense (BMD) discrimination, and missile communications. The AMDR-X will provide horizon search, precision tracking, missile communication and terminal illumination. Both radars will be integrated into a suite by the RSC. The RSC will provide the appropriate interfaces between the AMDR-S, AMDR-X, and combat system. The RSC will perform all coordinating actions to ensure that both radars operate in concert in a widely diverse environment. This solicitation will address the AMDR-S and RSC technology development of the AMDR suite through a Technology Development Review (TDR) and a Preliminary Design Review (PDR).
