### Project DN9 — Modular Electro-Magnetic Spectrum Sys (MEMSS)

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.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| MEMSS Software Design | — | 5.8 | 1.9 |
| MEMSS Prototyping | — | 1.5 | 0.2 |
| MEMSS Technical/Program Management | — | 1.4 | 0.4 |
| MEMSS Test/Demonstration | — | 0.5 | 0.2 |

> R-2A activities carry the prior, current and budget year only — no five-year plan. Coverage is partial, so count them, never total them.

## Where the FY2027 request goes

| Category | Share | $M |
|---|---|---|
| Government labs & warfare centers | 17% | 0.5 |
| Other / unspecified | 83% | 2.3 |

> R-3 exhibit contract funding, not USAspending obligations.

## 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.
