Advanced Self Protection Jammer

Also known as
  • ASPJ
  • ASPJ Pod
  • Advanced Self-Protection Jammer
  • Advanced Self-Protection Jammer Pod
  • External Airborne Self Protection Jammer

The Advanced Self Protection Jammer is an Indian DRDO airborne electronic-warfare pod associated with the HAL Tejas self-protection fit. Official Indian releases describe it as protecting the aircraft against acquisition radars, fire-control radars, anti-aircraft artillery, and airborne multirole radars, while later procurement approvals extended related external self-protection jammer pods into Su-30MKI electronic-warfare planning.

Integration Notes

The public record supports ASPJ as an aircraft self-protection component rather than a stand-alone combat system. Its importance comes from how it extends the survivability fit of Indian fighters.
