| 摘要： | In October 2008, the U.S. Navy will begin construction of the first of two lead DDG 1000 Zumwalt-class destroyers--at an expected cost of $6.3 billion. Given the history of cost growth on shipbuilding programs, as well as the Navy's request for approval of a third ship, GAO was asked to assess the progress of the program. GAO examined (1) whether key systems can be delivered on time and work as intended (2) design maturity (3) shipyard readiness and (4) whether lead and follow-on DDG 1000 ships can be built within budget. To accomplish this, our work included analysis of schedules, ship progress reviews and cost estimates; interviews with Navy and other officials; and our own past work. From the outset, DDG 1000 has faced a steep challenge framed by technical sophistication, demanding mission requirements, and a somewhat unforgiving schedule. The Navy conceived a thoughtful strategy to meet these demands and has had success with several technologies and its design approach. Yet, the program did not proceed as planned and the Navy recently realigned the construction schedule for the first two ships to provide more time to finish key systems and software. Still, the Navy will produce--and in some cases install--key systems on the ship before fully demonstrating and testing them. Software development has proven challenging; the Navy certified the most recent software release before it met about half of its requirements. At this point--the first year of a 6-year construction schedule for the lead ships--the Navy may have exhausted its options for solving future problems without adding money and time. / Availability Note: Product reproduced from digital image.
