AN/ALQ-157 Infrared Countermeasures System

AN/ALQ-157 Infrared Countermeasures (IRCM) System
The AN/ALQ-157 Infrared Countermeasures (IRCM) system offers continuous, multi-threat jamming for helicopter and fixed-wing aircraft protection.

The AN/ALQ-157 IRCM System protects large, heavy-lift helicopters and medium-sized, fixed-wing aircraft from Band I, II infrared threats, including first-generation surface-to-air and air-to-air missiles. It can defeat multiple threats simultaneously and employ “jam-in-tube” capability for certain threats. With continuous active jamming and extreme adaptability features, the AN/ALQ-157 system provides constant protection.


  • Modular design
  • Reduced down time
  • Advanced reliability
  • Operator jamming code selection


More than 900 AN/ALQ-157 type systems have been delivered to support eight different aircraft types. The system has demonstrated its abilities in various environments and situations. BAE Systems is inspired by the work of the armed forces and therefore committed to developing state-of-the-art survivability products. The AN/ALQ-157 is versatile, flexible, and reliable, making the system a key element of a multilayered platform protection approach.
