Zumwalts have problems left to sort out. They'll get there someday but in the meantime the fleet needs DDGs and the shipyards need work to stay in business and to keep our skilled workforce available to us. Other navies incrementally develop their designs, such as China Type 052 series DDGs and Russia's Varjag, Kresta I, Kresta II and Sovremmeny classes, all of which share the same hull and machinery with different weaponry and superstructure. Don't let perfect be the enemy of good enough. Burkes are fine ships, as good or better than any other navies DDG.

Of course that requires developing and testing new VLS containers. <br /><br />The Zumwalts are innovative but lets get them fully sorted before series building them. AGS is far from sorted out and AMDR is not integrated yet. In time I think the Zumwalt minus AGS, replaced with more VLS cells and a five incher, may become the air defense cruiser the Navy needs. I really think that is its ultimate destiny.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-56930905285209576322014-04-23T10:48:36.979-07:002014-04-23T10:48:36.979-07:00My feeling is that if the US navy can get the Flig...My feeling is that if the US navy can get the Flight III ships in the water on time and at a reasonable cost then that is good enough for now. I think B.Smitty made a good case for that.<br /><br />As to the PVLS design, I wonder if a combination hot and soft launch missiles might be a better idea. Hot launched missiles remain in the bow of the ship (a reduced number with more spacing and armour) while cold launch missiles could be dispersed around the ship.<br /><br />The new RN type 26 frigate will have CAMM missiles (equivalent to the Sparrow) placed on either side of the ships superstructure.<br /><br />A replacement Harpoon missile with cold launch ability could similarly be dispersed around the ship.<br /><br />Davehttps://www.blogger.com/profile/06835011708104671751noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-53476313206295830422014-04-23T05:36:42.607-07:002014-04-23T05:36:42.607-07:00This comment has been removed by the author.B.Smittyhttps://www.blogger.com/profile/12650152449414871058noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-70464470482376240982014-04-23T05:24:29.316-07:002014-04-23T05:24:29.316-07:00This comment has been removed by the author.B.Smittyhttps://www.blogger.com/profile/12650152449414871058noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-249398262686633452014-04-23T05:08:04.954-07:002014-04-23T05:08:04.954-07:00B.Smitty, c'mon, be fair.

Of course, for some programs, like the JSF, if the product is poor then trying to leverage up front costs is pointless and counterproductive.<br /><br />He's also making an interesting point about technological superiority as a deterrent.ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-83745423323557808092014-04-23T04:57:29.671-07:002014-04-23T04:57:29.671-07:00B.Smitty: "Marginal extra survivability prob...B.Smitty: "Marginal extra survivability probably won't matter that much either" - That's the point I raised in the post. I have doubts that the PVLS is really that significant an improvement in survivability. But, if it is, one has to seriously question going ahead with a Flt III design that would have a known, significant survivability issue.ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-81296357730713942082014-04-23T04:56:14.427-07:002014-04-23T04:56:14.427-07:00This comment has been removed by the author.B.Smittyhttps://www.blogger.com/profile/12650152449414871058noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-58659570006903966552014-04-23T04:48:45.987-07:002014-04-23T04:48:45.987-07:00This comment has been removed by the author.B.Smittyhttps://www.blogger.com/profile/12650152449414871058noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-8531161222798632512014-04-23T04:14:54.686-07:002014-04-23T04:14:54.686-07:00Well said!Well said!ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-8780677058006639672014-04-23T04:14:00.461-07:002014-04-23T04:14:00.461-07:00B.Smitty, you did understand that when I spoke of ...B.Smitty, you did understand that when I spoke of numbers I meant relative to the enemy's numbers, not relative to an alternative of our own. A few more ships (especially less survivable ones) aren't going to make much difference if the enemy significantly outnumbers us regardless of which version of a ship we build.<br /><br />If we can build a significantly larger number of good-enough ships so that we'll have a large margin over the enemy, then that's fine. Being able to build a few more ships that are less survivable doesn't gain us much.ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-26670353221936897192014-04-23T01:57:43.540-07:002014-04-23T01:57:43.540-07:00Another change in the Flight 111 from the Flight 1...Another change in the Flight 111 from the Flight 11A is a larger hull achieved by increasing the width of the stern so as to take the increased mass and height of the AMDR .<br /> Nick<br /><br />http://www.janes.com/article/36512/navy-league-2014-usn-arleigh-burke-flight-iiis-to-feature-wider-stern-design<br /><br /><br />The preliminary design of the US Navy's (USN's) Flight III Arleigh Burke-class guided-missile destroyer features a wider stern than the current Flight IIA ships in order to accommodate the new Air and Missile Defense Radar (AMDR), the DDG 51 programme manager said on 7 April.<br /><br />Captain Mark Vandroff explained that because the AMDR arrays are heavier than the AN/SPY-1D(V) radar arrays on board Flight IIA ships, the stern modification was necessary to lower the Flight III destroyer centre of gravity.<br /><br />"The wider stern will displace more water, so you get more buoyant force ....

QUALITY has a quality all its own, and its called a 10 to 0 kill ratio.<br />When you have technology that far superior many people wont even try it on, because they know they cant even understand never mind compete with the continuous advancements.<br />And you can put a price on the deterrence effect.

[he said in a very friendly, lightly kidding tone] There's so many deeper issues that could be explored, here.<br /><br />What's better? To build a cheaper ship that is less survivable or a more expensive ship that is more survivable? Is a cheap, sunk ship really cheaper than a more expensive, floating ship?<br /><br />What does this say about the USN warship design philosophy?<br /><br />Is short term cost now the main design criteria for Navy warships? If so, what does that suggest about our prospects in a fight with China over the next 40 years?<br /><br />Is the Navy focused on warfighting or accounting as its primary job?<br /><br />Is accounting going to force us to build a flawed Flt III (too small AMDR, too crowded, no growth margin, sub-optimal survivability, etc.)?<br /><br />Is the lack of an in-house, dedicated ship design group (General Board and BuShips) negatively impacting our warship designs?<br /><br />Have we lost our focus on combat?<br /><br />Do you want to go to combat and bet your life in a "cheap" ship?<br /><br />What does this say about Navy leadership and their focus?<br /><br />Penny wise, pound foolish?<br /><br />Step up your game!
