Northrop Grumman demonstrated the capabilities of a communications intelligence sensor package derived from its Airborne Signals Intelligence Payload (ASIP) system on the U.S. Army’s RC-12 Guardrail. Northrop Grumman said the demonstration, which took place the week of Feb. 11 at the Lakehurst test bed facility in New Jersey, met all objectives demonstrating basic Guardrail requirements and exceeded sensor system stability and performance expectations. “The success of these test flights is an important milestone in modernizing the Guardrail fleet. It mitigated program development risks by leveraging the U.S. Air Force’s investment in ASIP and validated ASIP scalability in meeting the U.S. Army’s signals intelligence needs,” said Imad Bitar, vice president of Northrop Grumman Mission Systems sector’s Electromagnetic Systems Laboratory business unit. Guardrail is being significantly upgraded and enhanced under the Army’s Guardrail Modernization program. The project will extend the fleet’s operational life beyond 2020. For related news
