Aerojet, a GenCorp (NYSE: GY – News) company, has again earned The Boeing Company’s ‘Supplier of the Year’ award for its commitment to superior performance and customer satisfaction. Aerojet, who also won a Boeing Supplier of the Year award in 2005, was one of 11 companies honored last night for its 2007 performance.

Suppliers of the Year were selected from a pool of 250 Boeing Performance Excellence Award winners. These companies — a select group among Boeing worldwide suppliers — hold 2007 Boeing Performance Excellence Awards for achieving silver or gold levels of performance, based on quality and delivery metrics over a 12-month period. “We are proud to recognize the performance excellence of our 11 Suppliers of the Year who have demonstrated that they are the best in the Boeing supply base,” said Steve Schaffer, Boeing enterprise leader of Supplier Management and vice president and general manager of Supplier Management for Boeing Commercial Airplanes. “Boeing is committed to rewarding, retaining and developing our top-performing suppliers who share our focus on first-time quality and on-time delivery.”

Aerojet has been the sole supplier to Boeing for the F-22 Raptor welded titanium forward booms. The company is also the sole supplier of the second- stage engines for the Delta II rocket, a program managed by the United Launch Alliance, a joint venture of Boeing and Lockheed Martin to deliver payloads into low-Earth orbit. In addition, Aerojet supports the Focused Lethality Munition program for the U.S. Air Force, the Small Diameter Bomb program and the HyFly development program for scramjet engines. “It’s an honor for the Aerojet team to receive this award for the second time from The Boeing Company,” said Aerojet President Scott Neish. “Aerojet uses operational excellence and lean manufacturing to continually improve the products that we deliver to Boeing. Receiving this award again is a direct result of these continuing, focused efforts.”
