This follow-on effort covers repair requirements under a nine-year Period of Performance from 10 September 2029 through 9 September 2038, with initial forecasted NSNs listed in the attached RFI_Master List and subject to future modification. The government lacks technical data rights for these items and has designated the systems as commercial items, and no physical samples are available for evaluation. The contractor must furnish all material, support equipment, tools, test equipment, and services, and must provide, maintain, and calibrate all support equipment at its own or a subcontractor’s facility. Replacement materials or parts must equal or exceed the quality of the original materials or parts. Participation in this survey may not ensure participation in future solicitations or awards, and the government will not reimburse participants for associated expenses.
