The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the repair and modification of circuit card assemblies. This sole-source requirement necessitates that the contractor possess Government Source Approval prior to award, as the Government lacks sufficient data to contract with other sources. The circuit card assemblies are critical components used in various defense systems, and the successful contractor will be responsible for ensuring compliance with stringent repair and testing procedures outlined in the Statement of Work. Interested parties must submit their proposals, including necessary documentation for source approval, to Danielle Junod at danielle.m.junod.civ@us.navy.mil, with proposals remaining valid for a minimum of 120 days following submission.
