The Naval Surface Warfare Center Crane requires four Radio Frequency Transmission Switches with two options for three additional switches in subsequent one-year periods. This is a sole source procurement intended for Ducommun Labarge Technologies Inc. of Carson, California, as they are the Original Equipment Manufacturer. The switches are critical for maintaining countermeasure test sets used on A-10 and F-16 aircraft, and a purchase delay would negatively impact mission effectiveness. While the government intends to negotiate with one source, it will consider capability statements from other responsible parties for potential future competition. The performance location is not specified, and no budget information is provided.
