The fleet of three C-17s are operated by the Heavy Airlift Wing (HAW) at Pápa Air Base in Hungary. Boeing has more than 60 people supporting the effort, and Pápa Air Base was the first location where Boeing provided all C-17 operational maintenance. Boeing has supported more than 1,000 missions for the SAC C-17 airlifters, achieving a mission capable rate of nearly 94 percent during the five years it has provided maintenance, engineering and spares through a comprehensive performance-based logistics program.
