What PARASIM does

PARASIM is the flagship virtual reality parachute training simulator brand of Systems Technology, Inc. (STI), a privately held U.S. defense technology company operating through its STI Defense division. The product combines 3D virtual reality with physics-validated parachute dynamics and realistic instrumented canopy controls to recreate the full jump sequence — aircraft exit, canopy deployment, malfunction recognition and correction, navigation, and landing — for both premeditated airborne operations and emergency bailout/ejection training. The system is supported by a growing virtual canopy library of over 40 military canopies, developed in coordination with canopy manufacturers, and a multi-station PARASIM Network add-on that enables shared virtual environments for group mission rehearsal.

PARASIM's customer base is anchored by the U.S. military — the Army, Navy, Air Force, and Marine Corps — with additional deployment to allied defense organizations globally; civilian skydiving is a secondary segment. To date, the company has sold 400+ systems worldwide over a 35+ year history, establishing it as a self-described gold standard in parachute flight simulation. The product integrates with STI's broader VBS4 (Virtual Battlespace 4) simulation platform and supports HLA/DIS interoperability protocols, positioning it within a larger military training ecosystem.

The business model is built on direct enterprise field sales of specialized hardware systems combined with software licensing and ongoing canopy library updates, executed via phone and web-based sales inquiry channels. Pricing is not publicly disclosed and follows standard quote-based defense procurement. The company maintains an active social media presence and participates in defense industry events (e.g., Leapfest 2024) to support demand generation. No parent company, institutional investors, or venture funding is disclosed in the source data, and ownership appears to be founder-led or independent.

Core offering

PARASIM® is a patented virtual reality parachute training simulator that combines 3D VR with validated parachute dynamics and realistic instrumented controls to train military paratroopers and aircrew. The system recreates the full jump experience from aircraft exit through canopy deployment, malfunction recognition, navigation, and safe landing. It is complemented by PARASIM Network for multi-station group training and integration with VBS4 military simulation software.

Product overview

PARASIM offers a virtual reality parachute training ecosystem centered on the PARASIM® simulator platform, which has been the gold standard for over 35 years with 400 systems sold worldwide. The core PARASIM® Virtual Reality Parachute Simulator combines 3D VR with validated parachute dynamics for training paratroopers. This is augmented by the PARASIM® Network multi-station system for group training operations, and the PARASIM® Canopy Library offering over 40 virtual military canopies. Additionally, the company integrates with VBS4 (Virtual Battlespace 4), a separate military simulation platform for broader combat training scenarios.
