The Department of Defense, through the NAVSUP Weapon Systems Support office, is seeking contractors for the repair of five Indicator Altimeters for the country of Australia. The procurement involves providing labor, materials, and facilities necessary to restore these government-owned components to operational condition, specifically for the part number NV1653AM2 with NSN 9999-99-107-4821. This repair is critical as the government lacks the data required to perform the necessary repairs or manufacture the items, and the intent is to solicit only one source, Ontic UK, under FAR 6.302-1. Interested parties must submit capability statements within five days of the notice publication, and the primary contact for this opportunity is Michael Zuccarini at michael.zuccarini@navy.mil.
