The Electro Magnetic Spectrum Operations (EMSO) program, as outlined in Budget Line Item 4367 for the Navy and Marine Corps, is focused on enhancing the Marine Corps' ability to operate effectively within the electromagnetic spectrum (EMS). The primary objective of this program is to provide advanced electronic warfare (EW) capabilities that support force protection, fires and maneuver, spectrum management, and battlespace awareness.
The EMSO program is a critical enabler for the Expeditionary Advanced Base Operations (EABO) construct, which requires agile, resilient, and technologically advanced ground-based EW solutions to counter peer and near-peer threats.
The Multi-Function Electronic Warfare (MFEW) Family of Systems is one of the key components funded under EMSO. MFEW replaced the legacy Counter Radio Controlled Improvised Explosive Device (RCIED) Electronic Warfare (CREW) system, adding capabilities such as Counter-Unmanned Aircraft System (CUAS) and offensive EW functions. The goal of MFEW is to provide comprehensive force protection and EW support to Marine Corps units, enabling them to detect, disrupt, and degrade adversary communications and control systems. Recent procurement included mounted systems and laptop technical refresh units, supporting the operational deployment and sustainment of MFEW capabilities.
The Marine Electromagnetic Ground Family of Systems (MEGFoS) represents the future operational solution for ground-based electromagnetic warfare within the Marine Corps. MEGFoS is designed to replace MFEW and provide advanced capabilities such as artificial intelligence-driven signal identification, networked EW operations, and low probability of intercept/detection antennas. The system enables electromagnetic warfare operators to conduct on-site and remote electromagnetic fires, coordinate EW techniques across multiple platforms, and integrate with kinetic fires for comprehensive effects.
MEGFoS is being developed using open architecture standards (CMOSS/SOSA) in coordination with the Army, Navy, and Air Force. This approach aims to reduce proprietary hardware, lower weight and power requirements, and decrease training and sustainment costs.
The EMSO budget request includes funding for the procurement of MEGFoS Dismounted Backpack Systems and associated ancillary components and spares. This procurement reflects a strategic shift toward more mobile, flexible EW capabilities that can be employed throughout the Fleet Marine Force. The dismounted backpack systems are intended to provide Marines with the ability to sense, identify, and exploit the EMS, as well as disrupt adversary decision cycles and protect friendly spectrum access. The increase in funding is directly tied to the production and fielding of these new systems and the necessary spares to support them.
The ancillary components and spares line item supports both the MFEW and MEGFoS systems, ensuring that deployed units have the necessary equipment to maintain operational readiness. Ancillary components include items such as specialized antennas, cables, and integration kits for vehicles, while spares cover replacement parts required for sustainment. The budget justification notes that the increase in spares aligns with the planned production quantities, supporting the lifecycle management of these EW systems.
The ability to instantaneously sense, identify, and disrupt enemy capabilities using non-traditional attack vectors is essential for modern expeditionary operations. By investing in open architecture, networked EW platforms, and AI-driven signal processing, the Marine Corps aims to ensure its forces can maneuver and operate effectively in contested EMS environments.
Coordination with other services and adherence to open standards are additional objectives of the EMSO program, promoting interoperability and cost efficiency across the Department of Defense. The program's procurement and sustainment strategy is designed to provide scalable, adaptable EW capabilities that support both current operational needs and future force design requirements, ensuring readiness for evolving threats in the electromagnetic domain.
