What PLEXSYS Interface Products does

PLEXSYS Interface Products, Inc. is a 100% employee-owned defense simulation software company founded in 1986 by brothers John and Walt Ledoux in Camas, Washington. The company develops Live, Virtual, and Constructive (LVC) modeling and simulation systems used by US and allied military forces to conduct multi-domain training across air, land, sea, space, and cyber. Its portfolio is organized under the ADAPT (All Domain, All Phase Training) ecosystem and centers on environment generators (ASCOT 7, ASCOT 5), communications simulation (Sonomarc, PLEXComm VR), data-link interoperability (Direct Link Interface), after-action review (VADAAR 2), session management (Launch Control), environmental data (StrataSim), secure infrastructure (CASE-V, NIST 800-53 compliant), and diagnostics (Diagnostics 7.5). The company holds AS9100D, ISO 9001, ISO 14001, and ISO 13485 certifications, is a GSA Contract Holder (47QTCA22D005X), and maintains wholly-owned subsidiaries in Australia (Williamtown) and the UK (Lincoln) serving the Australian Defence Force and the UK Ministry of Defence respectively.

The business operates on a dual revenue model: perpetual and/or subscription licensing of simulation software products (ASCOT, Sonomarc, VADAAR, DLI, etc.) to defense organizations, complemented by professional services revenue from government contracts covering on-site support, system integration, cybersecurity, and program management — exemplified by a $5.5M Tinker AFB contract (2024) and a $3.38M US Space Command award (2025). The company also captures pass-through revenue as a component provider within prime-contractor stacks (BAE Systems OneArc, Northrop Grumman, Boeing, Thales). Go-to-market is enterprise field sales with dedicated business development managers for the US Air Force, US Navy, and international accounts, supplemented by major defense trade-show presence (I/ITSEC, IT2EC, IDEX, Farnborough, Singapore Airshow) and an annual PLEXSYS Users' Group (PUG). Recent strategic moves include the December 2025 strategic alliance with BAE Systems' OneArc division, a May 2025 partnership with Macquarie University and Australian DSTG to integrate AI training agents into ASCOT 7, a May 2025 CEO transition from Ron Wiegand to Mark Graper, and a planned July 2026 facility opening in Midwest City, Oklahoma.

PLEXSYS serves a customer base that includes every branch of the US military (USAF, USN, USMC, USA, USCG, USSOCOM, USSF, DoD), the UK Royal Air Force, the Royal Australian Air Force, the French Air and Space Force, NATO, and a roster of defense primes. The company employs approximately 227 people across nine countries and operates without external venture, private equity, or institutional shareholders. Its positioning is that of a focused mid-sized specialist in a growing military simulation and virtual training market projected to expand from $12.99B in 2025 to $17.67B by 2030.

Revenue model

1. Defense Simulation Software Licenses: PLEXSYS generates revenue through the sale of simulation software products including ASCOT, Sonomarc, VADAAR, DLI, and related modules. These are sold as perpetual licenses and/or subscription arrangements to defense organizations and military forces. The company operates as a GSA Contract Holder (47QTCA22D005X).
2. Defense Contracts and Professional Services: Revenue is generated through government defense contracts including recent awards from United States Space Command ($3.38M), contracts at Tinker AFB, and other military installations. Services include on-site support, integration, cybersecurity, program management, and training system support.
3. Strategic Partnership Integration: Partnerships with BAE Systems, Rheinmetall, and other defense primes for delivering integrated LVC training solutions. Revenue flows from being a component provider within larger defense simulation systems such as BAE Systems' OneArc division.
