NAVSEA Shipbuilding Support Office, Philadelphia, PA provides current Manufacturing Lead Time information to Navy planners, designers and acquisition managers responsible for the timely procurement of the latest design Navy ships. Lead time information is critical to effective budgeting and on-time delivery of basic material, hull mechanical and Electrical Components and Combat Systems. This paper will address the methodology for solicitation, statistical consolidation and final assessment of information provided by over 1300 domestic primary and secondary manufactures. Early detection of lead time change provides a basis for remedial action whereby critical paths may be selected, schedules altered, or substitutions provided. The paper will further address the status of the United States Industrial Base capacity to provide these materials, components and systems and compares the current industrial base with its status five and ten years ago. Loss of domestic capacity has resulted in sole or single source procurement and in some cases sole dependence upon a foreign source for critical subcomponents. The ability of United States manufacturers respond to peacetime programs and potential surge or mobilization requirements will also be examined.
