The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support MECH, is seeking to procure five units of a specialized folding seat, identified by NSN 1H-2090-015569604-X3. This procurement is critical as it involves supplies for which the Government intends to negotiate with only one source, due to the proprietary nature of the data required for purchasing or repairing the part, which cannot be economically reverse-engineered. Interested parties are encouraged to express their interest and capability to fulfill this requirement, with proposals being accepted within 45 days of the notice publication. For further inquiries, potential vendors can contact Jon Zeigler at (717) 605-5696 or via email at jon.zeigler@navy.mil.
