This is a Request for Information (RFI) for market research only, not a commitment to a future procurement. The Program Manager Intelligence and Cyberspace Operations (PM ICO) seeks information on advanced, near-ready Over-the-Horizon Sensor (OTH-S) technologies for long-range maritime detection to support the Terrestrial Collection Systems program. Responses must be detailed and specific, directly addressing the required capabilities outlined in a separate, secured attachment. To access the specific requirements document, respondents must first complete a non-disclosure agreement. The government will not reimburse any costs associated with responding to this RFI.
