From the CRS Report of Mar 2010 that discusses the DDG-51 and DDG-1000 programs,<br /><br />"The design was 88 percent complete at the start<br />of lead ship construction ..."<br /><br />So, yes, the ship is being built concurrent with design efforts. Worse, several of the critical technologies are still under development during construction and changes will have to be made to accomodate modifications as development of those technologies continues. From the same report, a discussion of the risk in the deckhouse design included this statement,<br /><br />"The Navy planned to fully demonstrate the integrated deckhouse prior to ship construction start in February 2009, but land-based testing was delayed. Testing is now scheduled to complete by March 2010—over a year after deckhouse construction began."<br /><br />Again, concurrent development and construction. Further, from the Mar 2012 GAO Defense Acquisitions report,<br /><br />"... all three ships are in or will soon be in fabrication. However, the program is still conducting development work on several of its critical technologies and most of them will not be fully mature and demonstrated in a realistic environment until after their installation on the ship."<br /><br />And, discussing the impact of development on construction,<br /><br />"According to program officials, the shipbuilder had to rework some areas on the first ship ..."<br /><br />"The DDG 1000 program is still conducting development work on several of its critical technologies."<br /><br />"... the potential for design changes remains until its critical technologies are fully mature."<br /><br />This is concurrency; perhaps not as bad as other programs but still the same flawed approach that is causing program delays and costing taxpayers money.<br /><br />I hope that answered your question. If you still believe otherwise, please share with us whatever you're aware of that leads you to believe that concurrency is not happening with the DDG-1000 program.<br /><br />Thanks for checking in.ComNavOpshttps://www.blogger.com/profile/09669644332369727431noreply@blogger.comtag:blogger.com,1999:blog-5579907756656776056.post-13739296657633122742012-06-28T09:27:37.519-07:002012-06-28T09:27:37.519-07:00Concurrency for DDG 1000?
