California-based Cubic Defense has secured a follow-on contract to deliver 140 P5 Internal Subsystems (IS) for Lockheed Martin’s F-35 Lot 21 production aircraft, further supporting the global F-35 combat training ecosystem. Developed alongside subcontractor Leonardo DRS, the P5 IS forms part of the broader P5 Combat Training System (P5CTS), enabling secure integrated live-flight training for both 4th- and 5th-generation aircraft while safeguarding sensitive tactics, techniques, and procedures. The P5CTS network records, distributes, and analyzes detailed training data in real time and post-mission environments, enhancing interoperability among US Air Force, US Navy, US Marine Corps, and allied partner aircraft. Cubic’s broader defense portfolio also includes soldier training systems, satellite communications, and weapons effects simulation programs for NATO and coalition forces. The contract reinforces the importance of advanced networked combat training as militaries prepare for increasingly data-driven multidomain warfare environments.
