18 -- SERVICE LIFE EXTENSION PROGRAM (SLEP) - PHASE III POC Contract Negotiator, Alan R. Mak, (310) 336-4735; Contracting Officer, Charles D. Watson (310) 336-4730. The Government intends to modify the last four Defense Satellite Communication System III (DSCS III) spacecraft acquired from Martin Marietta Astro Space (MMAS). The modification will include, at a minimum, the replacement of 40 Watt Traveling Wave Tube Amplifiers (TWTAs) in Channels 1 & 2 by 40 Watt Solid State Amplifiers, the addition of Electrothermal Hydrazine Thrusters (EHTs) to augment and increase the efficiency of the DSCS III propulsion system, and the replacement of two inboard solar panels with high efficiency material. Any persons or companies interested in this notice are to respond by submitting an unclassified Statement of Capabilities (SOC) not to exceed 10 pages in length within 15 days of publication of this synopsis. The SOC must clearly demonstrate the source-s ability to perform the following: a) Integration of all anticipated design changes, b) Verification testing in accordance with existing plans and procedures, c) Dynamic loads analysis, d) Properly balance the spacecraft, e) Qualification of new parts and devices, and, f) On-orbit testing and anomaly resolution for the modified hardware. The first modified satellite must be ready to begin system-level launch readiness testing at the MMAS Valley Forge, PA, facility 15 months prior to launch. The launch is currently planned for not later than July 1999. The estimated period of performance for the entire modification program is five years starting in February 1996. The spacecraft are currently stored and monitored by MMAS at their Valley Forge facility. The Government intends to contract with the incumbent contractor, MMAS, unless firms submit clear and convincing documentation demonstrating their ability to meet the Government-s require-ments. MMAS has designed, developed, and launched DSCS III satellites and is perceived to be the only known source capable of fulfilling the above requirements. This synopsis is for information and planning purposes only, it does not constitute a Request for Proposal (RFP). Information herein is based on the best information available at the time of publication, is subject to revision, and is not binding on the Government. The Government will not recognize any cost associated with the submission of the SOC. A determination by the Government not to compete this proposed action based upon responses to this notice is solely within the discretion of the Government. (0116)
