So defending against intrusions like this are more important than ever:
Computer spies have broken into the Pentagon's $300 billion Joint Strike Fighter project -- the Defense Department's costliest weapons program ever -- according to current and former government officials familiar with the attacks.
Similar incidents have also breached the Air Force's air-traffic-control system in recent months, these people say. In the case of the fighter-jet program, the intruders were able to copy and siphon off several terabytes of data related to design and electronics systems, officials say, potentially making it easier to defend against the craft.
As we slow down and decline to race, we can't afford to give away data that allows potential foes to sprint away.
UPDATE: We're standing up a new command to fight this war and the F-35 data loss isn't nearly as bad as the first report said. According to this.
