The required delivery period is from 25 August 2027 through 25 August 2031, with a total quantity of 26 units per line item. Performance of services will be at Tinker AFB, Oklahoma, as the destination for shipping. The government intends to solicit and negotiate with only one source, Rosemount Aerospace Inc., as the data needed for competition is not available, though all responsible sources may submit a proposal. No budget amount is specified, and there are no qualification requirements or set-asides for this acquisition.
