66 -- HARDWARE/SOFTW; ALID MIL-STANDARD 1553 INTERFACES/ON-SITE INSTALL SOL N68936-97-Q-2794 DUE 090397 POC Ana Aguon, Purchasing Agent, (760) 939-4126 The Naval Air Warfare Center, Weapons Division, China Lake, CA intends to procure, on other than full and open competition basis, for five (5) each of ALID Mil-Standard 1553A/B Interfaces and on-site installation to upgrade the F/A-18 Weapons System Support Facility's (WSSF) labs to meet the Six Bus Requirement from the current situation described herein; Current Situation -- There are seven(7) ALID systems in the F/A WSSF'S labs. In each ALID system, either five(5) or six(6) ALID 1553 interfaces are combined with the ALID shared memory in an enclosure that provides power, cooling, I/O ports, & selection controls. Two ALID systems have six(6) 1553 interfaces each, and five ALID systems have five (5) 1553 interfaces each., Six Bus Requirement -- Both the 13E and 13C Operational Flight Programs (OFPs) in the real F/A-18 avionics system support six(6) avionics buses as a standard. Current testing requirements dictate that all labs be based on six(6) avionics buses, and therefore that the five ALID systems currently only supporting five(5) interfaces each be upgraded to support six(6)dual redundant avionics buses. The interface required to meet the ALID upgrade requirements will be referred to as INTERFACE. 1: The INTERFACE must interface the simulation computers to the F/A-18E/F avionics and armament buses. The 20 Hertz & slower messages will be transferred via the ALID shared memory; a high frequency port is required for higher frequency messages. 2: The INTERFACE shall simultaneously support up to four simulation computers using VME and QBUS I/O buses, via the shared memory. 3: The INTERFACE shall synchronize the simulation computers and switch interface to the major frame (50msec cycle) of the aircraft Mission Computers. Two synchs are required: 1) An interrupt shall be sent to the simulation computers at the start of each mission computer (MC) major frame. 2) A TTL signal shall be asserted at the start of each major frame. The TTL signal synchronizes other data transfers within the labs performed by the switch interface. The F/A-18 E/F Interface Upgrade Specifications is an attachment to the solicitation N68936-97-Q-2794. This has been sole-source to Design Analysis Associates, Logan, UT for unique and compatibility reasons. The SIC Code is 3823, Size standard is 750 employees. Any firm believing they can provide these items shall submit a written response to be received at the Contracting Office no later than 5 days after the publication of this notice, clearly showing it's ability to provide the required INTERFACE/On-site installation, which will be considered by the Agency. All request shall be in writing and may be faxed to 760-939-4290, or send by mail to NAWCWPNS, Code 230000D, Attn: Ana Aguon, China Lake, CA 93555-6100. Award is expected to be made on or before 18 Sept 97. This acquisition is being awarded under FAR Part 12 procedures. (0238)
