Indonesia has started operating Leonardo's RAT 31DL/M tactical long-range radar to strengthen surveillance.
The Indonesian Ministry of Defense (MoD) announced in mid-July that the Indonesian Air Force (Tentara Nasional Indonesia-Angkatan Udara: TNI-AU) is operating a RAT 31DL/M, jointly produced by Leonardo and the Bandung-based state-owned defence electronics firm, PT Len Industri.
The RAT 31DL/M radar is currently operated by the TNI-AU's 221st Radar Unit based in Ngliyep, Malang, located in East Java, the MoD said.
RAT 31DL/M with a maximum range of 400 km can detect a variety of incoming airborne threats including ballistic missiles, the MoD added.
The MoD said the radar is also equipped with a device to resist electronic countermeasures (ECM).
Leonardo announced in January 2020 that it signed a contract with PT Len to provide a RAT 31DL/M radar to the TNI-AU to enhance the service's air-defence capabilities. Under the contract, PT Len would supply local components, provide infrastructure support, and conduct maintenance operations for the radar.
According to Janes C4ISR and Mission Systems: Land , RAT 31DL/M is an L-band, distributed, solid-state, transportable, 3D radar that has a weight of about 30,000 kg. The radar's antenna has a width of 4.5 m, a height of 6.5 m, and includes 42 rows of transmit/receive modules with 52 radiators per row. RAT 31DL/M can detect airborne threats up to an altitude of 30,500 m.
RAT 31DL/M is also operated by the air forces of Austria, Germany, and Italy.
