This procurement is intended for a Foreign Military Sales (FMS) buy for Australia and is being conducted as a sole source acquisition from L3Harris Technologies Inc., the Original Equipment Manufacturer (OEM), due to the lack of available drawings or data for alternative sources. Interested parties may submit capability statements or proposals within 45 days of this notice, although the government does not intend to delay the procurement process for source approval requests.
