Elbit Systems has acquired BAE Systems Rokar International from BAE Systems, Inc., the US-headquartered subsidiary of BAE Systems plc, for about $31 million.Jerusalem-based Rokar specializes in the development, manufacture, integration and support of high-end GPS receivers and guidance systems for advanced defense applications, Elbit said in a press release last week.Rokar employs some 100 workers at its Har Hotzvim office in Jerusalem, Elbit said. The acquisition is meant to strengthen the company’s portfolio in the field of precision-weapon systems in the air, sea and on the ground, it said. Some of Rokar’s technologies are already used in Elbit products, Elbit said.“There is increasing demand for our networked precision-fire solutions,” Elbit Systems president and CEO Bezhalel Machlis said following the acquisition. “Rokar’s technologies are integrated in our solutions, and the acquisition will further enhance our capabilities in this growing area of activity.”
