Boeing has joined forces with BAE Systems to update the fly-by-wire flight control computers of the F-15EX Eagle II and the F/A-18E/F Super Hornet.

In a press release published on Tuesday, BAE Systems said the FCC hardware and software upgrade will improve processing performance and cybersecurity and enable future integration of new technologies.

BAE Systems is the original manufacturer of the FCCs.

Older aircraft such as the F-15 variants relied on mechanical flight controls that had hydraulic lines or cables connecting the cockpit controls to the aerodynamic control surfaces. Newer fighters, however, have FBW flight control systems that use computers to process pilot inputs to the actuators. The FCC monitors the digital process and makes changes in real time for flight stability, increasing the safety and reliability of the aircraft.

As part of the technology update, a processor will also be added to the F/A-18E/F’s FCC to enable new capabilities.

“BAE Systems is a leading provider of highly integrated controls and this upgrade reflects our commitment to providing our customers with next-generation solutions,” commented Corin Beck, senior director of military aircraft systems for the company’s controls and avionics solutions. “Our advanced flight-critical solution ensures these platforms are ready for missions now and in the future, equipping the aircraft to support the integration of new capabilities.”

In July, the 142nd Squadron of the Oregon Air National Guard unveiled the US Air Force’s first two operational F-15EX during a ceremony at the Portland Air National Guard Base. Boeing has also secured a contract worth 1.3 billion US dollars Provision and maintenance of F/A-18 multi-role fighter aircraft for the US Navy.
