The Pantsir-S2 is an improved version of the Pantsir-S1 which uses the same missile launcher and anti-aircraft cannons. The Pantsir-S2 can launch new surface-to-air missiles which increases the range from 20 to 30 km. The Pantsir-S2 is also fitted with a new SOTS S-band search radar to increase the detection range from 36 km to over 40 km. The new Pantisr-S2 has entered in service with the Russian army in 2015. It was deployed in Syria to protect the Russian air force troops at the Hmeymim airbase in Latakia.
