OVERVIEW: The J/ALQ‑6 is a Japanese airborne jamming system developed for use on electronic warfare aircraft. It serves as an active radar countermeasure pod, designed to disrupt hostile radar and communications.

DETAILS: The acronym “ALQ” denotes an airborne countermeasure pod under the U.S. Joint Electronics Type Designation System; the “J/ALQ” prefix denotes Japanese-manufactured variants, here by Mitsubishi Electric and NEC for Japan Self‑Defense Forces. The J/ALQ‑6 fits onto platforms modified for electronic warfare, carrying receivers, antennas, and transmitters capable of intercept and noise deception across select radar bands. Developed in the 1980s alongside derivatives such as the J/ALQ‑2, ‑3, ‑4, and ‑5, it reflects progressive improvements in Japanese EW pod technology . Its role is to provide escort jamming, protecting strike packages or surveillance aircraft from enemy radar-guided threats. Details on exact frequency coverage, power output, and onboard electronics are not publicly confirmed.

FONCTION:
The J/ALQ‑6 is mounted on military fixed‑wing aircraft via standard under‑wing hardpoints and interfaced with onboard EW and mission computers. Upon radar threat detection via internal or auxiliary RWR systems, operators engage pod jamming profiles—intercepting, analyzing, then deploying tailored noise or deception pulses toward threat emitters.
