Slitherine Corporation

Slitherine Corporation, a Delaware-based small business, delivers Command Professional Edition (CPE) military simulation and strategic analysis software to Department of Defense agencies as a prime contractor (79% of recent awards) through purchase orders and an Other Transaction IDV, with a secondary subcontracting footprint under defense primes. The vendor competes across full-and-open and Total Small Business set-aside procurements; Total Small Business designations recur across four awards, while six of eleven prime awards carry no set-aside restriction.

Slitherine's capability portfolio centers on perpetual-license CPE software and SaaS-delivered simulation software supporting war gaming, operational planning, and strategic analysis. Representative prime work includes a $179,997 definitive contract from Pacific Air Forces (awarded September 2024, extending through September 2027) for a Command Professional Edition multiplayer license supporting five players; a $119,995 firm fixed-price purchase order from Air Combat Command (July 2025) for CPE software licenses to support time-sensitive projects and Office of the Secretary of Defense-level inquiries; a $95,996 purchase order from Air Force Research Laboratory (July 2025) for CPE premium licenses supporting research and development modeling; and a $47,998 Other Transaction IDV from the Marine Corps (January 2026) for CPE licenses under experimental evaluation. The vendor also holds a $47,998 NAVSEA purchase order (February 2025, Total Small Business) for CPE Premium software licenses and six months of standard support, and a $23,999 NAVSEA purchase order (April 2026, Total Small Business) for CPE software licensing with twelve months of support.

Customer concentration clusters in defense research and operational commands. The top five customer agencies by combined potential value account for 94% of awards: Air Force Materiel Command Research Laboratory (2 awards, $192 thousand), Pacific Air Forces ($180 thousand), Naval Sea Systems Command (4 awards, $180 thousand), Air Combat Command ($120 thousand), and the broader Air Force ($96 thousand). NAVSEA dominates by order count (4 awards) but not by dollar value; Air Force Materiel Command Research Laboratory anchors the dollar rankings despite placing only two orders.

Activity has grown modestly from five awards in 2024 to seven in 2025, with two awards booked in 2026 year-to-date. Two awards (combined potential value $204 thousand) reach completion within the next twenty-four months and face recompete exposure. Slitherine subcontracts to Mantech TSG-2 Joint Venture on Marine Corps Force Design 2030 research and development and Force Design and Modernization efforts for the Marine Corps Warfighting Laboratory Futures Directorate, delivering software components for simulation and force-structure analysis work. The vendor's award footprint carries obligated dollars ($1 million) exceeding combined potential value ($816 thousand), indicating invoicing ahead of ceiling constraints across the small-dollar, transactional purchase-order base.
