The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure 12 units of a flight-critical tablet under a presolicitation notice. The procurement is intended for a specific National Stock Number (NSN 1R-5895-016741419-RQ) and will be negotiated with only one source, as the Government requires source approval prior to contract award due to the critical nature of the item. Interested parties must demonstrate their capability to meet the requirements and submit necessary documentation for source approval, as outlined in the NAVSUP WSS Source Approval Information Brochures. For inquiries, interested vendors can contact Carmelena C. Oldroyd at (215) 697-2606 or via email at Carmelena.Oldroyd@navy.mil, with proposals due within 45 days of the notice publication.
