The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the procurement of 11 units of the NSN 7R-1680-016516051-P8, a commercial seat for an observer aircraft. This item is classified as flight critical, requiring government source approval prior to contract award, and only previously approved sources will be solicited. Interested vendors must provide detailed technical data and documentation as outlined in the NAVSUP Source Approval Information Brochures, as failure to do so will result in disqualification from the bidding process. Proposals must be submitted within 45 days of this notice, and inquiries can be directed to Kelly A. Gipson at (215) 697-4787 or via email at KELLY.A.GIPSON1@NAVY.MIL.
