Northrop Grumman To Equip Australian C-130J Fleet With Radio Frequency Countermeasures System

Northrop Grumman Corporation has been selected by the Royal Australian Air Force (RAAF) to provide the AN/ALQ-251 advanced radio frequency countermeasures system for its C-130J airlifter fleet.

  • The AN/ALQ-251 provides robust protection against advanced weapon systems and agile electronic warfare systems in dense electromagnetic spectrum environments.
  • The system gives aircrews full situational awareness, radar warning and precision direction finding of radio frequency threats.
  • RAAF C-130J integration takes advantage of commonality with a current United States Department of Defense program of record, reducing lifecycle costs and enabling interoperability.

Expert:
James Conroy, vice president, navigation, targeting and survivability, Northrop Grumman: “With the increase of advanced radio frequency threats, our digital AN/ALQ-251 system allows the RAAF’s C-130J fleet the freedom of maneuver to carry out its wide range of humanitarian and national security missions safely.”
