Tender Details

(I) This is a combined synopsis/solicitation for commercial products or commercial services prepared in accordance with the format in Revolutionary FAR Overhaul (RFO) Part 12 - Acquisition of Commercial Products and Commercial Services as supplemented with additional information included in this notice.
