The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of a sole source requirement for the Nose Gearbox, classified under the NAICS code 336413. This procurement is critical as the Government does not possess sufficient data to contract with sources other than the current approved supplier, necessitating Government Source Approval prior to award. Interested vendors must submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online, to be considered for this opportunity. For inquiries, potential bidders can contact Samantha Freedman at 215-697-6566 or via email at samantha.m.freedman.civ@us.navy.mil.
