The Israeli Ministry of Defense awarded Elbit Systems a $70 million contract to supply airborne electronic warfare (EW) systems, the company said Dec. 28.

The systems, developed by the company’s EW and SIGINT (signals intelligence) unit Elisra, are set to be delivered over a five-year period and will be installed on board all types of Israeli Air Force fighter jets, Elbit said.

The Institute for National Security Studies (INSS), an independent Israeli security research institute, estimates Israel has 426 F-15 and F-16 fighter jets plus 100 A-4 Skyhawk jets used for training or in storage as of 2014.

“We are proud to provide the Israeli Air Force, recognized as one of the world’s most advanced air forces, advanced EW systems, covering the full range of fighter jets, and we trust that this win will further enhance our position as one of the world’s leading EW manufacturers, Bezhalel Machlis, president and CEO of Elbit Systems, said in a statement.

“The modern global air combat arena is extremely challenging, and pilots are facing many new threats. Our systems provide a solution to a wide variety of current and future threats, and we hope that other customers will follow the IMOD and the Israeli Air Force and select our EW systems,” Machlis added.
