Rapiscan Systems, Inc., of Arlington, Virginia, protests the issuance of a purchase order to Science Applications International Corporation (SAIC), of San Diego, California, under request for quotations (RFQ) No. S-WHARC-09-Q-0030, issued by the U.S. Department of State (DOS) for gamma ray vehicle and cargo inspection systems. The RFQ was limited to vendors holding a Federal Supply Schedule (FSS) contract for the required items, and Rapiscan principally argues that it was improper to issue the order to SAIC because that firm’s FSS contract does not include all required items.
