CEO Message

We’ve come a long way… from a bet in 1982, that a Zenith-248 computer could make simulated data appear as real radar plots on an operational Command and Control (C2) console… to today, where PLEXSYS’ suite of Live, Virtual and Constructive (LVC) training solutions are used every day across the globe… to the future, where bold innovation constantly delivers more integrated capabilities and greater efficiency… our character and commitment stand as unfailing constants.

Integrity, excellence, teamwork, and agility define us and the value we bring to every customer. We approach each new requirement with bold solutions, disciplined processes, and world-class support. Success is defined in trust and partnership.

Thank you for the privilege of joining you on your journey, whether it be growing defense readiness or delivering government/commercial success.
