the US AIR FORCE PLANS F-15 EW UPGRADE monitor news US NAVY TO DEVELOP NEXT-GENERATION EW SIMULATOR The US Navy’s Naval Air Systems Command (NAVAIR) at NAS Patuxent River, MD, has released a Request for Information (RFI) for a Next-Generation Electronic Warfare Environment Generator (NEWEG) to provide higher fidelity simulation in support of testing and evaluation of new electronic attack (EA) threat capabilities, such as Electronically Scanned Array (ESA) or Active Electronically Scanned Array (AESA) technologies developed in programs such as the F-35 Joint Strike Fighter and the Navy’s NextGeneration Jammer (NGJ). New EW systems are featuring greater receiver sensitivity, higher fidelity signal processing, sensor fusion, complex directionfinding techniques and advanced jamming capafi bilities, which are driving the need for new threat b simulation capabilities. Requirements include the si ability to sense jammer beams, determine their a direction, characterize the waveforms, deduce the d intent and impact and generate an appropriate rein sponse simultaneously. Also noting cost and schedule as major considerations, the NEWEG RFI calls for an open architecture tu system with an expected 10-year life span. The current notional design consists of four independent cu subsystems described as a Software System Control su (SSC), Digital Generator (DGEN), Radio Frequency (S Generator (RFGEN) and Monitor and Analysis (MAA) G subsystem. The SSC subsystem will provide the casu pability to create, edit, monitor and operate realp time scenario simulations, including the creation of ti threat emitter definitions. This programming data th will w be handed over to the DGEN to produce a digitalpulse descriptor of the complex emitter environment p in real-time for precise transmission by the RFGEN subsystem via free-space radiation or direct injection to the system under test (SUT). NEWEG will network with other DOD hardware-in-the-loop EW test facilities and provide wideband, high-pulse density simulation with multi-beam characterization and analysis. The NEWEG’s minimal frequency coverage will cover 70 MHz to 40 GHz (objective coverage is 20 MHz to 100 GHz) with pulse density values of 5 MPPS (objective is 8 MPPS). The Navy plans to act as the lead system integrator of the NEWEG and to develop an open-architecture solution with limited proprietary content. It will pursue a two-block approach, which includes The Journal of Electronic Defense | December 2011 The US Air Force’s Aeronautical Systems Center, F-15 Division, at Wright-Patterson AFB, OH has issued a request for information (RFI) for a new, wide-bandwidth digital EW system to replace the existing Tactical EW System (TEWS) on F-15C/D and F-15E aircraft. TEWS, which was fielded in the 1980s, includes the ALR-56C radar warning receiver, ALQ-135 radar jammer and ALE-45 chaff and flare dispenser. The new EW system, dubbed Eagle Passive/Active Warning Survivability System (EPAWSS), is planned for initial fielding in the 2015-2025 timeframe and is expected to extensively leverage commercial off-the-shelf components. The RFI calls for “proven” solutions at Technology Readiness Level (TRL) 6. Although the Air Force plans to continue operating at least 200 F-15Es until 2035, the need to focus on fifth-generation F-22 , g and F-35 fighter programs has delayed critical upgrades, including its EW system. The current USAF F-15C/D and F-15E TEWS was designed to handle 1980’s-era radar 15 based ground and air threats and has undergone only minimal upgrades over the past 25 years. Last year, F-15 prime Boeing selected BAE Systems (Nashua, NH) to develop the next-generation Digital EW Suite (DEWS) suite for the international market. DEWS is reportedly based on similar EW technology provided for the Lockheed Martin F-22 Raptor and F-35 Joint Strike Fighter (JSF) EW suites. This includes an interleaving mode that allows for continuous jamming along with radar and RWR operation. Boeing has also announced a new “Silent Eagle” stealth (F-15SE) variant of the platform, including DEWS, which it hopes to offer to current foreign F-15 customers including Israel, Japan, Singapore, Saudi Arabia and South Korea. The Saudi government has requested new F-15s as well as EW upgrades for its existing fleet of F-15s via Foreign Military Sale channels. A contract for that effort is expected soon. Reponses to the EPAWSS RFI are due December 9. The solicitation name is EPAWSSRFI. The primary point of contact is David Morlock, (937) 904-6681, – J. Haystead
