The Naval Air Warfare Center Weapons Division in China Lake, CA intends to sole source the procurement of four specific Mercury Processor Cards from Mercury Mission Systems, LLC. This is because the items are required as direct replacements. Any firm believing it can fulfill this requirement may submit a written capability statement via email for consideration within 5 days of the notice's publication. All responsible sources must be registered in the System for Award Management (SAM) with a notarized letter. It is recommended that interested parties proactively maintain an active SAM registration, as processing can take several days.
