The Department of Defense, through the Department of the Navy's NAVSUP Weapon Systems Support, is seeking proposals for a sole source procurement of support bearings, specifically NSN 7R-1680-016823669-H5, with a quantity of 5 each required for delivery FOB origin. This acquisition is critical as the government lacks sufficient data to contract with sources other than the current supplier, highlighting the importance of these components in maintaining operational readiness. Interested vendors must obtain Government Source Approval prior to award and submit the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, which can be accessed online. For inquiries, potential bidders should contact Casey M. Brown at casey.m.brown20.civ@us.navy.mil.
