For today’s changing military missions, up-to-the-moment intelligence can mean the difference between success and failure. Since 1971, the U.S. Army’s Guardrail system has maintained its position as the most successful signal intelligence (SIGINT) targeting, collection, and reporting system in the world. Supported from the start by Northrop Grumman, this airborne SIGINT system provides operational commanders with near real-time intelligence, precise geo-location data and persistent targeting information. Furthermore, Guardrail’s state-of the- art technology supplies the foundation for meeting future mission requirements.

Tested, Proven, and Perfected

Guardrail is the original corps-level airborne battlefield surveillance system. Over the course of 35 years, Northrop Grumman has successfully partnered with the Army for the evolution and deployment of Guardrail, readying the system to confront an ever-changing terrain of enemies and threats. From humanitarian missions to crisis response to full-scale war, Guardrail has proven to be the decisive factor in a full range of military operations. The system’s worldwide deployment and on the frontlines of Operations Desert Storm and Operation Enduring Freedom and the Global War on Terror has helped tip the balance in favor of victory and continuously evolved the capabilities.

Today, Guardrail remains a vital tactical asset, providing the modern warfighter with an overwhelming and unparalleled advantage. Guardrail also offers the U.S. Army the most cost-effective, flexible, and low-risk solution for developing and migrating to the surveillance system of the future.
