Small Unmanned Aircraft System Electromagnetic Spectrum Procedures
This MARADMIN provides guidance on electromagnetic spectrum (EMS) compliance procedures for Small Unmanned Aircraft Systems (sUAS) operations. It clarifies that while O-6 commanders may grant authority to operate sUAS per recent SecDef guidance, all systems must still obtain Equipment Spectrum Certification (ESC) and frequency assignments from NTIA before use. The message outlines the step-by-step process for achieving EMS supportability and assigns responsibilities across Marine Corps commands to ensure compliance with Federal regulations.

1. Purpose. To provide amplifying guidance to ensure the Marine Corps remains compliant with Federal regulations while supporting ref (a). 2. Background. 2.a. Reference (a) authorizes O-6 commanders or equivalents to grant authority to operate (ATO), procure, test, and train with small Unmanned Aircraft System (sUAS) that are compliant with statutory limitations. 2.b. Reference (b) outlines Federal statutes in the context of management and use of the EMS for which regulatory authorities has been entrusted to the National Telecommunications and Information Administration (NTIA) which serves as the Federal Electromagnetic Spectrum (EMS) regulator under the Department of Commerce. 2.c. To ensure the Marine Corps can fight with and against unmanned threats while also complying with statutory regulations, the Office of the Deputy Commandant for Information (DC I), Information, Command, Control, Computers, and Communications (IC4) has identified requirements from refs (b)-(e) that can delay mission readiness when not followed early and correctly. 2.d. EMS supportability is the set of prerequisites that must be satisfied before operating in the EMS. Within the United States and Possessions (US&P), EMS supportability consists of: 2.d.1. Equipment Spectrum Certification (ESC): NTIA certification that the system conforms to U.S. allocations and technical rules; ESC is required before requesting a frequency assignment. 2.d.2. ESC is typically initiated in the acquisition process and typically only done once. Reasons for a sUAS ESC to be updated include requests to increase authorized locations and changes to the sUAS EMS dependent components (e.g., EMS band, power, etc.). 2.d.3. Frequency Assignment: Authority to operate in a stated EMS band, location/area, and timeframe using specified parameters. Use requires a valid assignment. 2.d.4. Regardless of their method of procurement or stage of acquisition, sUAS systems must meet EMS supportability requirements prior to fielding and use. 2.e. Authority: NTIA is the sole Federal authority for assignments in Federal EMS bands. 2.f. Non licensed (Title 47 U.S.C.) devices. Low power devices (e.g., in 900 MHz, 2.5 GHz, and 5 GHz bands) approved under FCC rules (e.g., Part 15, Part 95) must accept interference and meet labeling/ID requirements. 2.f.1. When used for a military function, COTS "non licensed" devices still require EMS supportability (ESC/assignment). 2.f.2. COTS gear without an FCC label/ID may be limited to Federal band ESC only, which can restrict operational bands/locations. 2.g. Ref (a) identifies the Defense Innovation Unit (DIU) Blue UAS Hub as a list of DoD-approved UAS, components, and software that is available for purchase and operation by all U.S. military units on all military installations. 2.g.1. Maintainers of the DIU Blue Unmanned Aircraft System (UAS) Hub acknowledge that a Blue UAS Hub ATO is not an EMS approval. 2.g.2. Blue UAS Hub ATOs include the text "use of Blue UAS is permitted in all locations where the gaining organization of the platform covered by the ATO has obtained the appropriate flight, safety, and spectrum approvals." 3. Concept of Operations. Basic Step by Step Process (How to Comply). 3.a. Identify the system. Document make/model, radios, firmware, waveform, bands, max power, antennas, GNSS, video downlink, datalink, and any SATCOM/EW payloads. 3.b. Check device status. If COTS, confirm FCC label/ID and the applicable FCC Part (e.g., Part 15/95). Note: FCC "non licensed" status does not waive Marine Corps EMS requirements. 3.c. Start ESC. Contact MARCORSYSCOM to initiate NTIA Equipment Spectrum Certification (include all technical data). Coordinate early for new or modified configurations. 3.d. Request frequency assignment. Through respective MEF of Installation Spectrum Manager. ESC is a prerequisite. 3.e. Receive approvals. Do not operate until ESC is approved and frequency assignment (or EA authorization) is issued and on hand. 3.f. Maintain compliance. If you change hardware, firmware, antennas, power, or waveform—or relocate to a new area—you may need updated ESC and/or a new assignment. 4. Tasks. 4.a. NTIA: National EMS regulator for Federal users in Federal frequency bands (i.e., Federal Departments, Agencies, Administrations). The NTIA certifies EMS dependent systems for use within the US&P and assigns frequencies for Federal agencies within the US&P. 4.b. FCC: National EMS regulator for non-Federal users in non-Federal frequency bands (i.e., state, local government, commercial, private internal business, and personal use). 4.c. DC I-IC4 publishes Marine Corps EMS policy; identifies Service level changes to meet senior leader sUAS intent while conforming to DoD/USG policy; supports DON efforts to streamline DoD spectrum approval processes. 4.d. Marine Corps Systems Command (MARCORSYSCOM). 4.d.1. Supervises and manages EMS supportability across the acquisition lifecycle, ensuring seamless integration of all Marine Corps EMS dependent equipment with the exception of program of record sUAS and aviation platforms. 4.d.2. Serves as focal point providing administrative and technical support to MARCORSYSCOM program offices, Program Executive Office Land Systems (PEO LS), Marine Corps Warfighting Lab (MCWL), and Fleet Marine Force (FMF) procurements, installations, and other entities for ESC and HNA coordination. 4.d.3. Seeks and maintains frequency assignments for systems tested or operated by Marine Corps acquisition program. 4.d.4. Ensures EMS supportability is planned for each milestone and maintained through sustainment and configuration changes. 4.e. Navy and Marine Corps Spectrum Center (NMSC). EMS supportability/coordination activity for Navy/Marine Corps; interfaces with NTIA and other stakeholders (e.g., FAA) for ESC and frequency assignments; conducts regional de confliction via NMSC regional Navy and Marine Corps Spectrum Offices (NMCSO). 4.f. Marine Corps Warfighting Lab (MCWL). 4.f.1. Ensures EMS compliance during experimentation; validates ESC for systems in events. 4.f.2. Obtains/maintains frequency assignments for experimentation; coordinates early with MARCORSYSCOM/NMSC for novel/emerging waveforms and host nation trials. 5. Coordinating Instructions. 5.a. Marine Forces (MARFOR), Marine Expeditionary Forces (MEF), and Marine Corps Installations Command (MCICOM). 5.a.1. Do not operate EMS dependent systems without ESC and a valid frequency assignment. 5.a.2. For COTS purchases, verify FCC labeling/ID, then initiate ESC and request assignments through MARCORSYSCOM/NMSC. 5.a.3. Maintain unit level configuration control and documentation (platform, radio, firmware, waveform, power, antenna, GNSS, video downlink). 6. Points of Contact. Direct all questions to the MARADMIN POC listed above. 7. Release authorized by Lieutenant General M. G. Carter, Headquarters Marine Corps, Deputy Commandant for Information.
