OVERVIEW: The Il-20M “Coot A” is a four-engine, long-range electronic reconnaissance aircraft developed from the Il-18D airframe by the Soviet Union. It was introduced in 1971 for tactical and strategic ELINT and COMINT missions in support of Frontal Aviation operations.

DETAILS: The Il-20M was designed by the Ilyushin Design Bureau in the late 1960s to provide electronic surveillance support for Soviet ground and air forces. It is powered by four Ivchenko AI-20M turboprop engines and features multiple fuselage modifications including side-looking radar installations, external antennas, and panoramic camera bays. The aircraft carries a crew of around 13, including electronic warfare operators and reconnaissance technicians. It integrates electronic intelligence (ELINT), communications intelligence (COMINT), and aerial photographic reconnaissance capabilities using dedicated onboard systems.

The Il-20M is equipped with the Igla-1 side-looking airborne radar (SLAR), Kvadrat-2 electronic intelligence suite, and SRS-7 Romb-4B system. Its systems enable the aircraft to perform direction-finding, radar mapping, and communications interception across tactical and strategic environments. It was widely used during the Cold War to monitor NATO activities and continues in service with modernized variants.

TYPE: Tactical ELINT/COMINT Reconnaissance Aircraft

FUNCTION: Used for signal intelligence collection, radar surveillance, and ground mapping to support electronic order-of-battle development, battlefield awareness, and strategic reconnaissance. Its combination of ELINT, COMINT, and imagery sensors makes it suitable for complex intelligence missions.
