The Defense Logistics Agency seeks sources to procure and repair Air Traffic Control support parts, specifically a Battery Box (NIIN 015892096), with an initial estimated quantity of two. The government does not possess the technical data package for these items. Interested suppliers must demonstrate repair or manufacturing capability through documentation like test results or past purchase orders. This is a sources-sought notice for market research only and is not a solicitation. Responses are voluntary and all associated costs are borne by the vendor.
