The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the repair and modification of a critical component, the Fitting, Hold Back, A (NSN 1720-01-533-4867). This procurement is a sole source requirement, necessitating government source approval prior to award, as the government lacks sufficient data to contract with other sources. The items are essential for shipboard systems that enable the launch and recovery of aircraft, highlighting their critical nature for operational safety. Interested contractors must submit proposals along with the required source approval documentation to Alexis Healy at alexis.healy@navy.mil, with proposals remaining valid for a minimum of 120 days following submission.
