A digital aircraft sensor for aircraft for intelligence, surveillance and reconnaissance missions has entered service with the Indonesian air force.

The SAGE electronic support measure by Leonardo-Finmeccanica is carried on a modified CN-235 maritime patrol aircraft.

Leonardo said the modification program led by PT Dirgantara Indonesia and U.S. company Integrated Surveillance and Defense.

The SAGE sensor system can identify the location of radio frequency emitters -- such as surface-to-air missile fire-control radars -- from a single aircraft, enhancing situational awareness.

The first CN-235 was modified in 2016, with SAGE being installed and integrated with the aircraft's tactical mission system. Airborne flight testing then took place during the summer.

Leonardo is working closely with ISD and PTDI to deliver this capability to the Indonesian air force and said it is looking forward to future business opportunities with the two companies.

SAGE is currently be used by South Korean maritime helicopters and is scheduled to enter service on Brazil next year.
