Guardrail Common Sensor (GRCS)

Guardrail Common Sensor (GRCS) is the U.S. Army’s current airborne integrated Signals Intelligence (SIGINT) platform that provides near real-time targeting information to tactical commanders and supports full-spectrum operations.

GRCS is hosted on a fixed-wing aircraft (King Air B200), designated RC-12X.

The GRCS fleet is comprised of 14 mission aircraft supporting multiple combatant commands and five training platforms. In Fiscal Year 2018, the GRCS mission aircraft’s economic useful life was extended until 2034.

Guardrail was originally built as a Cold War system to provide indications and warnings against adversaries in both the European and Pacific Theaters of Operation. The Guardrail system has been modernized since inception to maintain relevancy and to enable continued prosecution of emerging threats within the changing battlespace.

GRCS sensor capability produces high-accuracy Communications Intelligence (COMINT) and Electronics Intelligence (ELINT) for battlefield mapping of common and modern signals of interest for detection, identification and geolocation of known threats. The Distributed Common Ground System–Army (DCGS-A) Operational Ground Station (OGS) processing, exploitation and dissemination capabilities allow for real-time signal exploitation and reporting, ensuring information dominance to commanders.

GRCS data and payload tasking and mission operations support are provided by the 116th Military Intelligence Brigade at Fort Gordon, Georgia. The standard concept of operations supports both single-ship, multiship and cooperative operations utilizing Tactical Common Data Links (TCDL) and network based infrastructure back to Continental United States (CONUS) based garrison locations where it is correlated, exploited and disseminated to supported commands.
