58 -- REQUEST INFORMATION: RCS REQUIREMENTS FOR NAVY SHIPBOARD SHF COMMUNICATION RADIO SYSTEMS POC Karen Erickson, 02-33, 703-602-0619. Synopsis NO. 39. The Space and Naval Warfare Systems Command (SPAWAR) is the acquisition agent for Navy shipboard super high frequency (SHF) satellite communication (SATCOM) radio systems. An emerging operational requirement for shipboard SATCOM systems (SHF and other) demands that all above-deck portions of shipboard SATCOM systems (e.g. the antenna, radome, antenna foundation, antenna components located above-deck, topside structural additions necessary to install SATCOM systems) meet stringent radar cross-section (RCS), or high resolution radar backscatter, constraints. SPAWAR intends to ensure that future procurements of SATCOM antenna groups meet RCS requirements developed for specific ships or ship classes. SPAWAR requests the following information from all potential providers of SHF SATCOM shipboard antennas: Do you have now, or do you have the capability to determine, high resolution RCS (radar backscatter) characteristics of your SATCOM antenna system(s) in the size range of four to ten feet reflector diameter (plus radome if used)? Note: to be useful, RCS data should be expressed in terms of square meters or dBsm, relative to all azimuth and elevation rotations of a specific antenna, at identified look angles, and for identified frequency ranges. This is a request for information on the existence of relevant RCS data, not a request for RCS data itself. SPAWAR may follow up this request for information with additional requests for actual RCS data pertinent to specific antenna types and sizes. Interested parties must have access to a SECRET clearance and may obtain specific Navy SHF SATCOM antenna RCS requirements upon verification of security clearances and need to know. Since Small Business (SB), Small Disadvantaged Business (SDB), and 8(a) firms are a major concern of SPAWAR, all respondents should indicate their status as a SB, SDB, or 8(a), or the extent to which they could include SB/SDB or 8(a) as a significant part of a resultant procurement. For further information on specific RCS requirements and the process for validation of security clearances, contact LCDR M. Ziegler, PMW 176-4 or Mr. V. Popik, PMW 176-42A, at (703)602-7529 or (703)602-5297 respectively. This is not a request for proposals and the Government will not make any reimbursement for any costs in connection with providing requested information. This information will be used by Government personnel for planning purposes only. Any proprietary information furnished should be appropriately marked. (0116)
