BM/KG300G electronic countermeasures system

Also known as
  • KG300G
  • BM KG300G
  • KG300G self-protection jamming pod
  • KG300G airborne self-defence jammer pod
  • KG300G airborne self-protection jamming pod
  • KG300G EW pod

The BM/KG300G is a Chinese airborne self-protection jamming pod family for external carriage on combat aircraft, with public sources describing I/J-band radar jamming, automatic countermeasure selection, and integration with radar-warning and dispenser subsystems. The baseline pod is associated with CEIEC/CETC and SWIEE/SIWEE reporting, while 2024 coverage showed a smaller rotary-wing form on a Z-10 and compact pods on an FH-95 UAV.

Variants

Open sources distinguish the original cylindrical fighter-aircraft pod from newer compact forms reported on rotary-wing or UAV platforms; related KG-series pods are not treated as the same item unless a source names the KG300G lineage.

Public descriptions identify the original pod as an externally carried I/J-band self-defence jammer for combat aircraft, with a longer cylindrical body in later comparison reporting.

Rotary-wing KG300G variantCompact helicopter-carried form

Janes reported CCTV footage of a Z-10 carrying a redesigned KG300G, shorter and more rectangular than the fighter-aircraft baseline, with mounting features suggesting rotary-wing use.

KG600 SPJLater related self-protection jammer

Pucara Defensa described the KG600 SPJ as an evolution of the KG300G associated with Pakistan's JF-17, while noting fewer public details for the newer pod.

Carrier And Integration Context

The public record describes the KG300G primarily as a podded self-protection jammer rather than a stand-alone combat system. Platform reporting is useful because it shows how the same family moved from fighter-style external stations into compact forms for helicopters and UAVs.

Baseline carriage

GlobalMil describes the KG300G as an external-store jammer for combat aircraft, intended to counter hostile airborne or land-based weapon radars in the I/J band.

Rotary-wing form

Janes reported a redesigned KG300G on a Z-10 attack helicopter, shorter and more box-like than the baseline fighter-aircraft pod.

UAV carriage

Asian Military Review reported compact jamming pods on FH-95 underwing pylons, appearing to include a miniaturized BM/KG300G system.
