Kalkan (radar)

Kalkan (Turkish for "shield") is a phased array 3D search and track radar system for low and medium range air defense mission operations.

It is designed and manufactured by Aselsan, a Turkish corporation that produces electronic systems for the Turkish Armed Forces.

Kalkan is currently the main radar of the Turkish Armed Forces' mobile Air Defense Early Warning and Command Control System (HERİKKS) and Medium Altitude Air Defense Missile System Hisar, entering into service in 2008. ASELSAN introduced to the market a new version of the radar, KALKAN-II, and exhibited at International Defence Industry Fair (IDEF) 2017.

As part of the Next Generation Air Defense Early Warning Radar (KALKAN-II) Procurement Agreement signed between the Ministry of National Defense and ASELSAN in 2016, the acceptance of a total of 11 systems has been completed. The three dimensional radar systems are used as the main search radar of the Turkish Land Forces Command Air Defense Early Warning Command Control System (HERIKKS) and the Medium-Altitude Air Defense missile system (Hisar-O).
