Why America Simply Can't Build Anymore F-22 Raptors
The Raptor’s avionics were dated even before the jet was declared operational in December 2005. While the Raptor is the most advanced operational warplane in the Air Force’s inventory, its computer architecture dates back to the early 1990s. The core processors run at 25MHz–since it took so long to get the jet from the design phase to production. Moreover, the Raptor’s software is particularly obtuse and difficult to upgrade–which is partly why integrating the AIM-9X and AIM-120D missiles onto the aircraft has been so problematic.
