POSTMODERN WARFARE: The F-35’s Greatest Vulnerability Isn’t Enemy Weapons. It’s Being Hacked.

Every F-35 squadron, no matter the country, has a 13-server ALIS package that is connected to the worldwide ALIS network. Individual jets send logistical data back to their nation’s Central Point of Entry, which then passes it on to Lockheed’s central server hub in Fort Worth, Texas. In fact, ALIS sends back so much data that some countries are worried it could give away too much information about their F-35 operations.

Another networking system is the Joint Reprogramming Enterprise, or JRE. The JRE maintains a shared library of potential adversary sensors and weapon systems that is distributed to the worldwide F-35 fleet. For example, the JRE will seek out and share information on enemy radar and electronic warfare signals so that individual air forces will not have to track down the information themselves. This allows countries with the F-35 to tailor the mission around anticipated threats—and fly one step ahead of them.

Although the networks have serious cybersecurity protections, they will undoubtedly be targets for hackers in times of peace, and war. Hackers might try to bring down the networks entirely, snarling the worldwide logistics system and even endangering the ability of individual aircraft to get much-needed spare parts.

As aerospace engineer Will Collier explained to me several years ago, the F-35’s main strength is its sensor suite and networking capabilities. But that also introduces new vulnerabilities, as this report underscores.
