The Naval Surface Warfare Center (NSWC) Crane requires one detector replacement, 12-month preventative maintenance, and 12-month software maintenance. The government intends to sole source this requirement to North Star Imaging Inc. under FAR 13.106-1 because these items are already integrated into the customer’s system. All responsible sources may submit a capability statement for consideration, though the government retains discretion over competition. Performance will occur at NSWC Crane, and the contract includes 12-month service periods for maintenance and software.
