### Project 0602 — Electronics W/F Env Simulation (ECHO)

The objective of this project is development of necessary simulation facilities and approaches to allow determination of the effectiveness of Electronic Warfare (EW) in real world engagement situations and to support the introduction of modern, effective EW systems into Naval Aviation platforms. The heavy use of test resources by all Services demonstrates the importance of these assets. The Electronic Warfare Environment Simulation project is unique because it is the only program within the Department of War which develops and provides Naval anti-air warfare threat assets for Test and Evaluation (T&E). This project directly supports the T&E resource requirements for all Naval Air EW development programs, to include radio frequency situational awareness and countermeasures. Programs in development and future programs include: Joint Strike Fighter, EA-18G, Low Band Transmitter, Next Generation Jammer, Advanced Anti-Radiation Guided Missile (AARGM), Long Range Anti-Ship Missile (LRASM). This project provides for the development of an Integrated Air Defense T&E capability to be fielded at each of the three sites comprising the Navy's Tri-Center complex: Naval Air Warfare Center Weapons Division, China Lake and Point Mugu in CA, and Naval Air Warfare Center Aircraft Division, Patuxent River, MD.

### Project 0672 — Effect Nav E/W (ENEWS)

The objective of the Effectiveness of Naval Electronic Warfare (EW) Systems (ENEWS) Project is the development, maintenance, upgrade and application of critical simulation assets to determine the effectiveness of Electronic Warfare (EW) systems for the Surface Navy in simulated real-world engagement scenarios. ENEWS provides the Navy with Anti-Ship Missile (ASM) simulators, Modeling and Simulation (M&S) and state-of-the-art evaluation facilities to support the introduction of modern, effective shipboard and off-board EW systems and tactics for EW Programs of Record (POR). ENEWS develops, maintains and operates hardware simulators, digital simulations (M&S) of legacy, modern and advanced threat ASMs that provide EW PORs an integrated simulation capability through at-sea captive carry field trials with flyable simulators, digital ASM models and the Central Target Simulator (CTS) hardware-in-the-loop evaluation facility. The reliance of ENEWS assets by the Naval Sea Systems Command, Operational Test and Evaluation Force (OPTEVFOR), Office of Naval Research (ONR) and other EW Research, Development, Test and Evaluation (T&E) agencies speaks to the overall importance of this project. The project provides support and effectiveness evaluations for EW system designs, Engineering Test (ET), Development Test (DT), Operational Test (OT) events including and the development and utilization of techniques and tactics. In the past, ENEWS quick reaction capabilities have provided significant support and solutions in crisis situations such as the Libyan crises, Iran threat, Persian Gulf crisis, Operation Desert Shield/Storm, the Ukrainian Crisis in the Black Sea, and the crisis in the Red Sea. Simulation Display (SIMDIS) is a modeling tool developed under the ENEWS Project to support visualization of test events. SIMDIS has been adopted by most Department of War (DoW) T&E ranges as an effective tool that provides two and three dimensional graphical and video displays of live and post-test event data for EW T&E. One of the primary threats to surface ships is ASM systems. The ENEWS Project is unique in that it is the only project within DoW dedicated to developing and providing realistic ASM assets to test and evaluate the effectiveness of shipboard EW systems and tactics against these types of threats.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| Hardware Simulation Systems | 3.3 | 4.8 | 4.2 |
| Simulation Characterization, Verification and Requirements | 0.5 | 0.5 | 0.5 |
| Support and Computers Simulation Systems | 2.6 | 2.8 | 2.4 |

## Mission & acquisition strategy

This is a continuing program that consolidates the design, fabrication and integration of Naval Electronic Warfare (EW) threat simulators for increased managerial emphasis and coordination. These simulator development efforts provide realistic Developmental and Operational Test and Evaluation environments to test EW systems and defensive tactics. These projects develop threat Anti-Air and Anti-Ship weapon system simulators in accordance with the Services' requirements.
