This RFI seeks access to commercially owned UHF-capable MEO satellite bandwidth for a near-term experimental campaign to characterize spectrum and waveform operations, demonstrate interoperability with existing GEO systems, and inform a pathway to augment or replace GEO UHF capabilities. The government strongly desires on-orbit service as soon as possible, with an Initial Launch Capability by 2030 considered potentially useful but earlier solutions preferred. No specific budget amounts are mentioned. The location for performance of services is not specified. The campaign focuses on using existing space vehicle and payload capabilities for an initial prototype step toward providing UHF services from MEO.
