Northrop Grumman and the Air Force successfully demonstrated the migration of B-21 ground systems data to a cloud environment. This demonstration included the development, deployment and test of B-21 data, including the B-21 digital twin, that will support B-21 operations and sustainment. This robust cloud-based digital infrastructure will result in a more maintainable and sustainable aircraft with lower-cost infrastructure.
