This procurement is critical for maintaining operational capabilities, as the items are essential components for helicopter rotor blades and drive mechanisms, and no alternative sources are available due to the lack of data rights. Interested parties may submit capability statements or proposals within 15 days of this notice, with the anticipated award date set for September 2025; inquiries should be directed to Jacob R. Wells via email at Jacob.r.wells1@navy.mil.
