‘Significant new capabilities have been added to the US Air Force’s latest superfighter, the F-22 “Raptor”. The USAF’s Raptors cost more than $300m each, and are generally thought to be the most advanced combat jets in service worldwide. However, until recently they were unable to cross the international date line owing to a software bug in their navigation systems.
A group of F-22s heading across the Pacific for exercises in Japan earlier this month suffered simultaneous total nav-console crashes as their longitude shifted from 180 degrees West to 180 East.
Luckily, the superjets were accompanied by tanker planes, whose navigation kit was somewhat less bleeding-edge and remained functional. The tanker drivers were able to guide the lost top-guns back to Hawaii and the exercises were postponed.’
