This is a notice of intent that AFSC/PZABB, Electronic Warfare Sustainment, intends to issue a definitive contract to provide engineering and technical support services to AN/ALM-246 TEWS Intermediate Support Station (TISS) in support of the AN/ALR-56C Radar Warning Receiver (RWR) Test Program Sets (TPS). The services in support of this acquisition will provide analysis, problem investigation, problem resolution and testing, and software updates concerning the AN/ALR-56C TPS on the TISS. This action will result in the award of a new, cost-plus-fixed-fee, definitive (C-type) contract consisting of a twelve month period of performance. No options are included under this effort.
The proposed contract action is for services for which the Government intends to solicit and negotiate with only one source under the authority of 10-U.S.C. 2304 (c) (1) as implemented by FAR 6.302-1. The Government intends to solicit Boeing (CAGE: 0PXV4) who is the OEM.

F-15 Avionics
The F-15 aircraft system has 63 avionics LRUs that require ILM, including instrumentation, displays, flight computers, navigation systems, EW, and sensor equipment. Currently, ILM for avionics is conducted in the context of an avionics back-shop within the wing component maintenance squadron (CMS) at each location. ILM for an LRUis performed using one of three types of automatic test stations: the AN/GSM-397(V) electronic system test set (ESTS), TISS, and antenna (ANT) A/B. The ESTS is a second-generation test station that replaces five individual stations in the original F-15 avionics intermediate system(AIS).
The Loral AN/ALR-56A RWR is designed to detect incoming radar signals, identify and characterize these signals to a specific threat, and alert the aircrew through the TEWS display. The AN/ALR-56
system features four external antennae mounted on the each fin tip and on both wingtips, with a fifth blade-shaped antenna underneath the forward fuselage. The solid state ALR-56 is based on a digitally-controlled dual channel receiver that scans from 6-20 GHz, while changes in the threat can be accommodated by software modifications.
The ALR-56C Radar Warning Receiver (RWR) detects a broad range of incoming radar signals, identifies and characterizes the probable source as a specific friend or threat, and alerts the aircrew through the TEWS display. It also manages companion AN/ALE-45 and AN/ALQ-135 countermeasures systems.
The F-15′s Tactical Electronic Warning System (TEWS) includes Electronic Support Measures/Electronic Counter-measures (ESM/ECM) equipment such as the Loral AN/ALR-56C radar-warning receiver (with aerials in the fin tips, wing-tips, and under the fuselage), the Magnavox AN/ALQ-128 threat-warning receiver, Tracer AN/ALE-45 counter-measures dispenser, and Northrop AN/ ALQ-135 jamming system.
An F-15 Tactical Electronic Warfare System (TEWS) Operational Assessment report for the ALR-56C RWR (Suite 1 Operational Flight Program - OFP) was released by AFOTEC in Mar 95. RWR deficiencies included the following areas: memory capacity, processor throughput, threat ambiguity resolution, and false alarms.
Future RWR improvements requested via the F-15 OFP update process could not be met (Suite 4 and beyond) unless a new processor and memory capacity upgrade program was initiated. Specific RWR SORD requirements were not met in Suite 2&3 due to current processor/memory limitations in selected threat environments.
