Joint Secure Air Combat Training System (JSAS)

Readiness without boundaries

The next-generation system for secure, Live, Virtual and Constructive (LVC)-capable training is here. JSAS, a collaboration from Collins Aerospace and DRS Training & Control Systems, brings all the capabilities together for high-fidelity air combat training.

JSAS provides the first certified, four-level Multiple Independent Levels of Security (MILS) training equipment in both airborne and ground equipment, allowing for tethered and autonomous operations. MILS provides secure interoperability between 5th-Gen and 4th-Gen aircraft, bringing significant training benefit to all participants in a simulated, high-threat combat environment. Further, JSAS supports LVC training now.

Features & benefits


Blends synthetic elements with live participants to realistically simulate highly congested and contested combat situations

  • Full-fidelity threat and weapon simulations for Department of Defense and NATO weapon types
  • Real-time kill notification and removal with real-time RTO adjudication
  • Reconfigurable in flight for effective training in less time
  • Able to securely integrate with aircraft data bus/operational flight program
  • 5x more network capacity than existing air combat training systems, in the same bandwidth – more live players and excess capacity for LVC traffic


Not only is JSAS real, certified and operating on ranges today, it’s also designed to advance as your future training needs change

  • Leverages newly developed security and data-link technologies with decades of air combat training expertise
  • Overcomes limitations in live threats and training infrastructure
  • Provides rapid training response to emerging missions and threats
  • Open architecture simplifies obsolescence management and future upgrades with new technologies and lends itself to interfacing with a variety of debrief and live monitoring software systems
