This opportunity is for the procurement of Servo Valve Hydraulic spares (NSN: 1650001377073) used on the T-38 aircraft, with a base quantity of 55 units and a range of 14 to 83. The required delivery of 55 units is by January 1, 2028, with early delivery acceptable, and the destination is SW3210. The government intends to solicit and negotiate with only a limited number of sources, specifically MOOG INC and THOMAS INSTRUMENT INC, as the data rights are not owned by the government and reverse engineering is uneconomical. No budget amount is specified, and no qualification requirements exist for this part. Performance of services is not specified, as this is a spares procurement with delivery to a government destination.
