The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of pumps for systems 1 and 2 as part of a Foreign Military Sales (FMS) initiative. This procurement is a sole source requirement, necessitating Government Source Approval prior to award, as the Government lacks sufficient data to contract with sources other than the current supplier. The items are critical components in aircraft hydraulic systems, underscoring their importance in maintaining operational readiness for military aircraft. Interested vendors must submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, and inquiries can be directed to Anna Kiessling at 215-697-3752 or via email at ANNA.M.KIESSLING.CIV@US.NAVY.MIL.
