The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking to procure three units of the hydraulic accumulator (NSN 7R-1650-011589683-VH, REF NR 70103-28041-042) as part of a sole source requirement. This procurement is critical as the government lacks sufficient data to contract with any source other than the current supplier, emphasizing the importance of these components in aircraft hydraulic systems. Interested vendors must obtain Government Source Approval prior to award, and proposals must include the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, available online. For inquiries, potential bidders should contact Casey M. Brown at (215) 697-3752 or via email at casey.m.brown20.civ@us.navy.mil.
