The Naval Air Warfare Center Weapons Division in China Lake, CA intends to sole source the procurement of four 1553 Hardware Kits (P/N: TCG-1553U) to Curtiss-Wright Defense Solutions. This is for direct replacement parts already in use. Any firm believing it can fulfill this requirement may submit a written capability statement for agency consideration within 5 days of the notice's publication. All responsible sources must have an active registration in the System for Award Management (SAM), which now requires a notarized letter.
