The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is soliciting proposals for the procurement of Air Turbine Starters. This is a sole source requirement, indicating that the government does not possess sufficient data to contract with any source other than the current approved supplier. The Air Turbine Starters are critical components used in various aircraft systems, necessitating government source approval prior to award for any new suppliers. Interested vendors must submit the required documentation as outlined in the NAVSUP WSS Source Approval Brochure, which is available online. For inquiries, potential bidders can contact Samantha Freedman at 215-697-6566 or via email at samantha.m.freedman.civ@us.navy.mil.
