Discriminating Technical Capabilities & Subsystem Integration

To demonstrate capability, the source must possess proprietary technical data, manufacturing capability, and existing integration knowledge to provide the following:

• Technology Pedigree and Re-use: The proposed system must be built upon the established baseline of F-15 Saudi Advanced (SA) Digital Electronic Warfare System (DEWS) and F-35 hardware/software architectures. The respondent must demonstrate that a minimum of 11 of the 14 baseline primary Line Replaceable Units (LRUs) (or their direct advanced/upgraded iterations) have been previously tested, fielded, and proven to ensure zero regression in existing capabilities.
• Target Aircraft Compatibility: Complete hardware and software compatibility with F-15E and F-15EX models equipped with APG-82(v)1 or APG-63(v)3 radars and the Advanced Display Core Processor II (ADCP II). The system must feature an integrated Interference Blanking function to provide interoperability with other aircraft radio frequency (RF) systems.
• Software and Mission Data: Proven ability to develop, test, and sustain the EPAWSS Operational Flight Program (OFP) and the Windows/PC-based Mission Data File Generator (MDFG). The system must allow for field reprogramming and data download (Maintenance and Environment) utilizing Common Aircraft Portable Reprogramming Equipment (CAPRE) over Ethernet.
• Dense Threat Environment Performance: Proven, previously validated capability to counter a minimum baseline of 321 legacy, new, and emerging threats within at least three (3) distinct dense background environments (military, commercial, and civil signals).
• Advanced Threat Simulation & Validation: Proven performance against high-fidelity, realistic threat waveforms (including LORO, TWS, AESA, and agile emitters). To be considered capable, this performance baseline must have been previously validated using a minimum of 36 RF signal generators at the Air Force Research Laboratory (AFRL) Integrated Demonstrations and Applications Laboratory (IDAL), verified via Hardware in the Loop (HITL) validation of Electronic Countermeasures effectiveness against test asset emitters, and have completed Initial Operational Test & Evaluation (IOT&E) on the F-15E with a recommendation to field.
• Radar Interface: The system must include a specifically designed Radar Interface Module (RIM), or its direct next-generation equivalent, that natively interfaces with the APG-82 radar via a fiber-optic connection on the F-15E and F-15EX to guarantee zero system interference.

Specific Hardware Components (Group B Kits)

The capable source must have the immediate manufacturing and testing capabilities to produce the specific LRUs and Line Replaceable Modules (LRMs) that comprise the Eagle Passive Active Warning Survivability System, including but not limited to:

• Critical LRM Technologies: The immediate capability to manufacture specific, highly complex LRMs based on proprietary existing architectures, including the baseline or advanced iterations of the Digital Channelized Receiver (DCR) and DCR/Target Generator, as well as the Quad Tuner Module (QTM) and Quad Upconverter Module (QUM).
• Digital Processors with associated Aircraft Interface Module (AIM) and Countermeasures Dispenser I/O Modules
• Interface Blanking Units
• Power Conditioning Distribution Units (PCDU) and Power Supplies
• Solid State Transmitters (L/R Fwd, L/R Aft)
• C/D Band Blade Antennas, Receive Antennas, and Transmit Antennas
• Expanded Expendables Capacity: The system must fully integrate ALE-47 Countermeasures Dispenser (CMD) capability and utilize Dispenser Sequencer Assemblies (DSAs) that provide a minimum baseline of a 360 single-squib capacity (utilizing at least six (6) DSAs with two 1x1 magazines each).
• Countermeasure Compatibility: Full integration, firing compatibility, and historical testing with the following specific baseline expendables (and any modernized variants): MJU-71, MJU-48, MJU-51, MJU-53, MJU-50, MJU-66, MJU-64, XS1201, M-206, and MJU-62/B.
