The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for the procurement of hydraulic reservoir and other replacement parts, specifically identified by NSN 7R-4320-015366991-RQ and reference number 3671223H705-5, with a quantity of one unit required for delivery FOB origin. This procurement is critical as the item is flight critical, necessitating government source approval prior to contract award; only previously approved sources will be solicited, and new sources must submit detailed technical data and experience documentation with their proposals. The importance of these parts lies in their role in maintaining operational readiness and safety for naval operations. Interested vendors should contact Kathryn S. Hull at (215) 697-1219 or via email at KATHRYN.HULL@NAVY.MIL for further information, and must ensure compliance with the Source Approval Information Brochures available on the NAVSUP website to be considered for the award.
