Yet another KC-46A Category 1 problem - fuel leaks between the 2 containment systems - several aircraft need to reworked at the factory - production stopped due to COVID-19. This is in addition to the other long-term Cat 1s - rear vision system and flying boom.
So fuel, flying boom and rear vision - everything that matters - all now Cat 1 problems !
Category 1 deficiencies are defined by the USAF as issues “which may cause death or severe injury; may cause loss or major damage to a weapon system; critically restricts the combat readiness capabilities of the using organisation; or results in a production line stoppage”.
