This is a solicitation for 139 spare AC generators (Part Number 977J330-3) for the F-16 aircraft, with a required delivery on or before February 20, 2026, to destination SW3210. The government does not own the technical data needed for manufacture, so interested firms must contact the OEM, Hamilton Sundstrand Corporation. The acquisition is not set aside, and while it is intended for a limited number of sources, all responsible sources may submit a proposal. The contract award is contingent on the availability of appropriated funds.
