Cubic Secures Follow-On Contract for F-35 P5 Internal Subsystems

Why It Matters

The contract strengthens the U.S. and partner militaries’ ability to conduct realistic, data‑rich training, a critical edge in modern air combat readiness.

Key Takeaways

• Cubic awarded 140 P5 Internal Subsystems for F‑35 Lot 21
• Leonardo DRS serves as principal subcontractor on the program
• Live‑environment joint training capability expanded for coalition forces
• P5 CTS now active on 30+ ranges across 17 countries

Pulse Analysis

The new Cubic Defense contract underscores the growing demand for advanced training infrastructure as the F‑35 fleet reaches full‑rate production. By delivering 140 P5 Internal Subsystems for Lot 21, Cubic not only deepens its foothold in the high‑value defense training market but also reinforces Lockheed Martin’s supply chain resilience. The P5 Combat Training System’s ability to capture, transmit, and analyze granular flight data in real time is essential for shaping tactics that keep pace with evolving threats, making it a strategic asset for the Air Force, Navy, Marine Corps, and NATO allies.

Real‑time data exchange, known as TSPI (time, space, position information), is at the heart of modern joint exercises. The expanded P5 IS deployment enables coalition pilots to train on a unified platform, reducing interoperability gaps and accelerating decision‑making cycles. With more than 30 air ranges in 17 countries already integrated, the system facilitates cross‑border drills that mirror contested environments, thereby enhancing collective readiness and deterrence posture.

From a market perspective, Cubic’s win signals confidence in U.S. defense contractors’ ability to deliver secure, scalable training solutions amid tightening budgets. The partnership with Leonardo DRS adds depth to the supply chain, combining Cubic’s software expertise with DRS’s hardware capabilities. As defense budgets increasingly prioritize simulation and live‑virtual‑constructive training, firms that can provide end‑to‑end data solutions are poised for sustained growth, positioning Cubic as a key player in the next wave of combat readiness technology.
