The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for a sole source contract related to the procurement of power supply converters, classified under the PSC code 6130. This requirement arises from the government's inability to obtain sufficient, accurate, or legible data to contract with sources other than the current supplier, necessitating Government Source Approval prior to award. The items are critical for military operations, and interested vendors must submit the necessary documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online. For inquiries, potential bidders can contact Casey Brown at 215-697-3752 or via email at casey.m.brown20.civ@us.navy.mil.
