Thales has delivered the first two Ground Master 403 (GM403) long-range air surveillance radars to Indonesia as part of a 13-unit program intended to strengthen the country’s airspace monitoring network. The systems are being supplied in partnership with state-owned defense electronics company PT Len Industri under a contract running from 2023 to 2028, according to company disclosures.
The GM403 is a variant within Thales’s Ground Master 400 family, a fully digital, active electronically scanned array 3D radar designed for long-range air defense. It provides coverage from very low to very high altitudes and is capable of tracking fast, highly maneuverable aircraft as well as small, low‑radar‑cross‑section targets such as unmanned aerial vehicles and cruise missiles.
Under the arrangement, Thales is responsible for the radars and the associated SkyView command-and-control system, while PT Len is in charge of building radar stations, installing and integrating the systems, and handling civil works. The radars are to be deployed across the Indonesian archipelago to create a more comprehensive air picture for the Indonesian National Armed Forces, enhancing detection and tracking of air threats over the country’s vast maritime and land territory.
