Cubic Global Defense is to produce and enhance the Air Combat Training System in the F-35 Joint Strike Fighter, the company has announced.

Included in the work contracted by Lockheed Martin Aerospace is the addition of an internally mounted sub-system of the P5 Combat Training System, or P5CTS, that enables the F-35 to maintain its stealth characteristics while training.

The P5CTS is designed to provide secure, real-time and post-mission training for air-to-air, air-to-ground and surface-to-air combat missions by displaying live-air picture, recording mission data, and relaying time, space and positioning information between participating aircraft during training flights.

The P5 training system is an encrypted system interoperable with the P5CTS/Tactical Combat Training System used by the U.S. Air Force, Air National Guard, U.S. Navy, U.S. Marine Corps and many international partners.

Cubic said that under the new low-rate initial production contract from Lockheed Martin, it is to produce additional JSF P5 systems.

The announced production came in a series of contracts from Lockheed Martin Aerospace, the company said, but no details as to their financial value were disclosed.
