In addition to providing space for the work of the Oklahoma City Air Logistics Center, the Tinker Aerospace Complex can also be used to house public/private business partnerships. Currently there are three programs. The Cooperative Research and Development Partnership has the objective of advancing science and technology to meet Air Force requirements and transferring technology into the commercial marketplace (CRADA, governed by Title 15 USC 3710a). Public Private Partnerships, or statutory partnering, is where the government acts as a seller to private industry in either a direct sales agreement, Workshare Partnering Agreement, or a Facilities Use Agreement (governed by Title 10 USC 2474). Finally, the Enhanced Use Lease requires Congressional approval and full fair market value rent for underutilized Air Force assets(governed by 10 USC 2667).
