58 -- HIGH FREQUENCY COMMUNICATION SYSTEM MODERNIZATION POC J. Oxman, 02-32, (703)602-1133. Synopsis No. 62. The Space and Naval Warfare Systems Command (SPAWAR) is identifying possible replacement equipment for High Frequency (HF) communications systems aboard Navy ships. SPAWAR is interested in identifying sources able to provide Non-Developmental Items (NDI) or Commercial Off-the-Shelf (COTS) systems, subsystems, or components for a modernized shipboard HF communications architecture. The potential offeror must have production equipment available for demonstration, test data available verifying functional and environmental performance; and supporting commercial literature. Any historical pricing information is also desired. Examples of ships targeted to receive the modernized HF systems are CV, DDG 993, DD 963, SSN 688, AO, FFG, MCM, and others which require HF equipment improvements in FY98 and beyond. Separate configurations may be considered for ships with from 2 to 4 transmit channels, from 5 to 7 transmit channels, and for 8 or more transmit channels. Systems requirements include support of: Voice, USB, LSB, and ISB modes, FED-STD-1045 and MIL-STD-188-141A automatic link establishment (ALE) on at least two channels, secure Internet Protocol (IP) routing over HF (e.g., HF e-mail), MIL-STD-188-110A and NATO STANAG 4285 with transmission rates up to 9600 bps, and frequency shift keying (FSK), MIL-STD-188-203-1A Link 11, Transmit frequencies from 2.0000 MHz to 29.9999 MHz, Receive frequencies from 14.0000 kHz to 29.9999 MHz. An example of an HF communications architecture presently envisioned includes, but is not limited to: TRANSMIT RF DISTRIBUTION AND ANTENNA SUBSYSTEM based upon narrowband antennas, easily switched transmission paths, and frequency selective, rapidly tuning antenna couplers. TRANSMIT SUBSYSTEM with quickly tuning transmit channels, capable of remote control of frequency, mode, and power (from .01 W to Maximum power). Transmit channels capable of a maximum power output of 100 W to 1000 W are of interest. RECEIVE SUBSYSTEM with small broadband antennas and RF distribution systems not requiring tuning, and frequency scanning receive channels that can be remotely controlled. CONTROL SUBSYSTEM that supports ALE, IP exchange, and data communications. Depending on cass of ship and number of circuits, the HF equipment system may be controlled by its own central monitor and control system, may be controlled by AN/SSQ-33(), or may not warrant central control. Sources are encouraged to propose control options and describe the characteristics of their remote control capabilities including bus and protocol standards(eg, Simple Network Management Protocol (SNMP)). Sources are encouraged to propose alternative architectures and provide descriptions and performance characteristics of systems and components available. The Navy is interested in identifying systems that are easy to operate and maintain; systems that will also reduce the size and weight of HF equipment, and provide rapid channel configuration/reconfiguration, and facilitate ALE. Sources are asked to state the availability of systems or components for installation in a Navy ship or laboratory for demonstration. Sources are also requested to: Identify and describe the operational environment for which the NDI/COTS system/component is designed, Provide data and references to validate commercial market acceptability and product support history, identify current commercial and military users of the product(s), describe the ability to fault isolate using Built-In-Test/Built-In-Test Equipment (BIT/BITE). Systems must be capable of meeting Navy environmental, and interface requirements, and complying with MIL-STD-461 for Electromagnetic Compatibility/Electromagnetic Interference (EMC/EMI). Proprietary data in the responses will be protected where so designated. Sources must identify whether they are Large Business, Small Business (SB), Small Disadvantaged Business (SDB), or 8(a) Set-aside. This is not a request for proposal nor does the Government intend to pay for information solicited or equipment demonstrated. Closing date for submission of responses is thirty days after publication of this notice. Acknowledgment of receipt will not be made nor will telephone inquiries be honored. Literature of a general nature is neither required nor desired. Responses should be addressed to: Space and Naval Warfare Systems Command, Code 02-32A, 2451 Crystal Drive, Arlington, VA 22245-5200 (0249)
