BAE Systems plc completed the 300th conversion of an F-4 Phantom fighter jet into a remote-controlled aerial target used by the U.S. Air Force for weapons testing and aircraft training. More than 100 BAE employees perform work on the QF-4 aerial targets at the London aerospace and defense company’s 123,000-square foot hangar in Mojave. The Mojave Air & Space Port has performed the conversions since 1996. The company will deliver another 14 QF-4s by the middle of next year. Each conversion takes about six months and can include systems engineering and integration; electrical, mechanical, and software engineering; and various types of structural alterations. “Our proven performance on this program exemplifies our global capabilities to upgrade and modify aircraft,” said Gordon Eldridge, vice president and general manager of Aerospace Solutions at BAE Systems, in a prepared statement.
