As part of the total Navy effort, the Area Air Defense Commander (AADC) capability is a command and control system element for execution of the Area and Navy Theater Wide TBMD and Joint Warfare programs. The AADC effort is currently in the concept development phase of the acquisition process, and the Naval Sea Systems Command is soliciting proposals for short-term concept studies for an AADC capability. This synopsis amends the Broad Agency Announcement N00024-99-R-5107 released on 19 November 1998 in the Commerce Business Daily. The following amendments are made: (1) The 8th objective of the BAA states the objective as "Cost of the proposed AADC conceptual design with supporting rationale." An offeror should interpret "[c]ost of the proposed AADC conceptual design" to mean at least a rough order of magnitude (ROM) estimate of the engineering and manufacturing development costs and a per unit cost of production. The offeror should assume 12 production units and include costs to complete development and production of the proposed design.. This cost estimate should not include life cycle cost beyond production.(2) Offerors are required to submit one (1) copy of their Technical Proposal in Microsoft OFFICE '97 electronic format (i.e., in WORD, EXCEL and/or POWERPOINT files) on 3.5" IBM Formatted diskette(s), ZIP drive or CD-ROM with their proposal submission. This requirement is in addition to the paper copy requirements for proposals submitted in response to this announcement. (3) The date for receipt of proposals is hereby extended to 2:00 P.M. Eastern Standard Time on 01 February 1999 Posted 01/06/99 (W-SN285399). (0006)
