The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of a Power Control Assembly, identified by NSN 7R-1680-017163760-RQ. The procurement involves a quantity of five units, which are flight critical, necessitating government source approval prior to contract award, as the technical data available does not support full and open competition. Interested vendors must provide detailed documentation as outlined in the NAVSUP WSS Source Approval Information Brochures, and failure to submit the required information will result in disqualification from the award process. For inquiries, vendors can contact Nadia Govorushko at (215) 697-2813 or via email at NADIA.GOVORUSHKO@NAVY.MIL.
