The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking contractors to repair one unit of BLD AIR SHUTOFF VLVZ for the country of Japan. The procurement involves providing labor, materials, and facilities necessary to restore the specified aircraft component, which is critical for the operational readiness of the E-2 aircraft. The government intends to solicit only one source, Northrop Grumman Systems Corporation, due to the lack of available data for repairs or manufacturing, but will consider proposals from all responsible sources submitted within five days of the notice. Interested parties should contact Ethan Stein at 215-697-2983 or via email at ethan.stein@navy.mil for further details and must comply with the Source Approval requirements outlined in the NAVSUP-WSS Source Approval Information Brochure for Repair.
