The 763d Enterprise Sourcing Squadron at Scott Air Force Base, Illinois intends to award a firm-fixed-price sole-source contract to Slitherine Corporation for three Command Professional Edition software licenses. The contract covers a three-year period, with a base year from September 16, 2026, to September 15, 2027, plus two optional years extending through September 15, 2029. Performance will be for the benefit of Headquarters Air Mobility Command/A9, with the contracting office located at Scott AFB, Illinois. Slitherine is considered the only responsible source for this highly specialized modeling and simulation software due to proprietary and licensing restrictions. While the government will issue a solicitation directly to the intended source, other responsible parties may submit capability statements for consideration in future acquisitions, though the government will not reimburse any costs incurred in responding.
