PARK ELECTROCHEMICAL CORP. ANNOUNCES SELECTION BY NORTHROP GRUMMAN CORPORATION OF PARK’S PATENTED SIGMA STRUT™ FOR THE JAMES WEBB SPACE TELESCOPE

Melville, New York, Wednesday, May 8, 2013……Park Electrochemical Corp. (NYSE – PKE) announced that its patented SIGMA STRUT™ has been selected by Northrop Grumman Corporation (NYSE – NOC) for use on the James Webb Space Telescope (“JWST”). The JWST is a large, infrared-optimized space telescope developed by an international collaboration among the National Aeronautics and Space Administration (NASA), the European Space Agency (ESA) and the Canadian Space Agency (CSA). The main industrial partner for the project is Northrop Grumman. The JWST project is scheduled to launch in 2018.
