The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking proposals for the repair and modification of an alternating current motor, identified by NSN 7R-6105-009509625-LU, with a quantity of 21 units required. This procurement is critical as the item is flight critical, and the government does not possess sufficient data to procure it from sources other than those already approved. Interested vendors must provide detailed technical data and source approval documentation with their proposals, as new source approvals typically cannot be processed in time to meet government needs. Proposals must be submitted within 45 days of this presolicitation notice, and interested parties can contact Shannon R. Menickella at (215) 697-2198 or via email at SHANNON.R.MCNEILL.CIV@US.NAVY.MIL for further information.
