The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of three units of a flight-critical item identified by NSN 7R-5999-015492395-CB and reference number 232A310-1. Due to the specialized nature of this item, which requires Government source approval prior to contract award, only previously approved sources will be solicited, and new sources must submit detailed technical data for evaluation. This procurement is crucial for maintaining operational readiness, and interested vendors must ensure compliance with the Source Approval Information Brochure to be considered for award. For inquiries, potential bidders can contact Dana L. Scott at dana.scott@navy.mil, with proposals due within 15 days of this notice.
