A sole source procurement is contemplated with Aerojet Ordnance Tennessee, Inc. (AOT), 1367 Old State Route 34, Jonesborough, TN, 37659-6315. AFRL/RWMI requires 5000 pounds of tungsten cubes and/or spheres, sintered to a density of greater than 18.4 g/cc military grade tungsten, sized in various dimensions between 1/4 inch and 1 inch cubed/diameter, plus or minus 0.010 inch tolerance. In order for the overall material testing program to have validity and continuity, it is mandatory that the above described test material is the exact same composition as previously tested tungsten, and AOT was the supplier of these previous test materials. Additionally, the material properties of the required material must have the same mechanically strengthened and heat treated processes applied under the same conditions as previously tested materials. If a vendor other than AOT provides the materials, it would require extensive revalidation of materials and strength testing adding extensive costs and program delays of up to one year. However, all interested parties may submit statements of capability (SOC) which should, if possible, include at least three references of the above materials having been provided to customers for use as preformed fragments in weapons; these will be considered if received by noon central time zone on 16 Mar 09. Submit to: Air Force Research Laboratory (AFRL/RWK), Attn: Mark Fitzgerald, 101 W. Eglin Blvd., Ste. 337, Eglin AFB, FL 32542-6810. Please refer technical questions to Mr. Matthew Matyac, 850-883-1973, and business questions to Mark Fitzgerald, 850-883-2670.
