TEL AVIV (Reuters) - Israeli defense firm Elbit Systems Ltd ESLT.TA said on Monday it won contracts worth $136 million to provide customers in Asia-Pacific with airborne laser direct infrared countermeasure (DIRCM) systems.

These systems are designed to protect aircraft against heat-seeking ground-to-air missiles.

The contracts will be carried out over four years.

Under the contracts, Elbit Systems ESLT.O will equip fleets of Airbus AIR.PA and Boeing aircraft BA.N with DIRCM systems, including the company’s infrared missile warning systems.

These contract awards follow recent awards to install DIRCM systems onboard Airbus A400 aircraft of the German Air Force and onboard NATO’s Airbus A330 multinational multi-role tanker transport fleet.
