Leonardo RAT 31 DL/M Radar Indonesian Air Force

Primary Air Defence Sensor for NATO Finding New Customers

Leonardo has signed a contract with Indonesian company PT Len Industri (Persero) to provide a RAT 31 DL/M radar system for the Indonesian Air Force (IAF), the company announced on 21 January. The IAF will operate the radar to strengthen the Indonesian air defence system.

PT Len Industri will supply local components, infrastructure support and expert radar maintenance. For this contract and future programmes in-country, the two companies plan joint production of radars in Indonesia.

The contract followed an announcement made in November 2019 at the Defense & Security exhibition in Bangkok, where Leonardo revealed it will also provide a RAT 31 DL to the Royal Thai Air Force. The RAT 31 DL/M has already been acquired by the Italian, German and Austrian air forces, a well as an unspecified North African nation.

The RAT 31 DL/M is part of Leonardo’s RAT 31 radar systems family and it shares its architecture with the RAT 31 DL Long Range GCI (Ground Control Interceptor) – an advanced, L-band, solid state solution for 3D surveillance, with an effective range of over 470 km. It protects against air and missile threats, including ballistic missiles, for homeland security and expeditionary missions. The radar system can adapt to the challenges posed by a broad range of operational scenarios, including confronting jamming and heavy clutter at the same time. Its highly reliable solid-state technology allows for ‘graceful degradation’ under which, even if some radar modules fail, overall radar performance is maintained.

Over 50 RAT 31 DL systems have been sold worldwide. It is NATO’s primary air defence sensor, meeting alliance standards for air defence radar architecture and allowing for full interoperability.
