    Background, Purpose, and Objective

    PM ICO is responsible for the Terrestrial Collection Systems (TCS) program of record, which encompasses both Ground Sensors (GS) and Maritime Sensors (MS). The TCS program will include a persistent, long-range sensor, independent of national and theater collection assets, to provide Maritime Domain Awareness (MDA) and Intelligence, Surveillance, and Reconnaissance (ISR) tipping and cueing against targets operating in open ocean beyond the range of the littorals. An Over-the-Horizon Sensor (OTH-S) will detect adversary surface targets at extended ranges in support of the Marine Corps’ Stand in Force (SiF) mission to hold adversary ships at threat and inform joint kill chains. It provides the SiF an organic long range collection capability that does not depend on theater or national assets and is all-weather operable.

    PM ICO seeks information on advanced stage Technology Readiness Level (TRL) OTH-S’ and their projected availability for fielding and deployment.
