Operation SECURE (State Emergency Capability Using Radio Effectively) - intrastate/interstate and state/federal interoperability MF and HF network, similar in scope and function to SHARES. Analogous to the VHF/UHF nationwide interoperability frequency plans. Like many US government HF radio networks, Operation SECURE uses frequencies allocated to the maritime mobile service and the fixed/mobile services.

Some states appear to not have current/valid licenses for the SECURE network frequencies. Like the SHARES network, SECURE is used as a backup for, and in conjunction with Internet teleconferencing systems, secure dedicated telephone links (including hardened four-line systems) between state Emergency Operations Centers, FEMA HQ and other important government offices and UHF/SHF/EHF SATCOM systems.
