The contemplated firm fixed price contract covers a minimum quantity of 27 units, a best estimated quantity of 106 units, and a maximum quantity of 159 units, with delivery required by July 24, 2028. All responsible sources may submit a bid, proposal, or quotation, though foreign-owned firms must contact the contracting officer or program manager beforehand to determine award restrictions. The government intends to solicit and negotiate with a limited number of sources because it does not own the manufacturing data rights, meaning interested firms should contact the original equipment manufacturer, Hamilton Sundstrand Corporation.

Proposals will be evaluated based on a combination of price and past performance factors.
