Modular Electro-Magnetic Spectrum System (MEMSS) is an EW capability providing Force Protection and Freedom of Maneuver through Radio Frequency (RF) Technical Effects, an overarching cover term for a classified capability. MEMSS will provide accelerated delivery of innovative RF technical effects solutions tailored to Army requirements. FY 2027 funding in the amount of $2.807 million supports the program in prioritizing iterative development, incorporating vendor Research and Development (R&D) investments and readily available Commercial-Off-The-Shelf (COTS) components. Further advocacy for MEMSS capabilities exists in support of the Joint community, Operational Needs Statements (ONS), Transformation in Contact (TiC) initiatives, Presidential Directives, and other Combatant Command requests.

FY2027 planned work FY27 funding will continue to support the development and integration of key software modules for: command and control of COTS hardware prototypes, algorithms for processing sensor data to verify accuracy of programming, and a user-friendly graphical user interface (GUI) to visualize data and manage RF Technical Effects operations. The Army will fund a Federally Funded Research and Development (FFRDC) agency to work with Industry to develop expanded capability of current GOTS software products.

FY2026 to FY2027 change FY 2027 funding decrease due to reduction in testing and software development in support of prototyping efforts to support Soldier Touch Points (STPs).

FY2026 plans — current year FY 2026 funding will support the development and integration of key software modules, including: development of software to control and configure COTS SDRs and other RF components, enabling precise control of RF parameters (frequency, power, modulation). Development of algorithms for processing sensor data to detect, identify, and classify RF signals. Creation of a user-friendly graphical user interface (GUI) for operators to control the system, visualize data, and manage RF Technical Effects operations.

Program detail

Mission & acquisition strategy

This Program Element (PE) encompasses engineering and manufacturing development for tactical Electronic Warfare (EW). The Integrated Electronic Warfare System (IEWS) is a capability set that integrates electronic attack, protect and support functions to dramatically improve the ability to seize, retain, and exploit an advantage within the electromagnetic spectrum (EMS). It is based on a modular, scalable and open architecture to allow Army Brigade Combat Team (BCT) and Joint Force Commander's to tailor capability responses against a variety of EW threats/scenarios.

The MEMSS acquisition strategy will leverage the Adaptive Acquisition Framework to deliver operationally and tactically relevant expendable hardware and software RF Technical Effects capabilities to the Warfighter. The Army will leverage available commercial and government-off-the-shelf (COTS/GOTS) technical solutions to enable rapid prototyping and experimentation of systems. MEMSS program plans to utilize the Middle Tier of Acquisition (MTA) Rapid Prototyping (RP) authority. Prototyping efforts will inform system requirements and future acquisition pathways.
