B-2 Bomber Now Has Improved Digital Communication Capabilities

Northrop Grumman in partnership with the U.S. Air Force, completed an integrated airborne mission transfer (IAMT) demonstration with the B-2 Spirit at Whiteman Air Force Base as part of the ongoing modernization efforts incorporating digital engineering.

IAMT enables the B-2 to complete a digital, machine-to-machine transfer of new missions received in flight directly into the aircraft. IAMT is part of Northrop Grumman’s B-2 Collaborative Combat Communication (B2C3) Spiral 1 program that digitally enhances the B-2’s communications capabilities.

The demonstration included approximately 50 mission transfers during a two-day period in partnership with the Air Force. Aircraft vehicle 1086, the Spirit of Kitty Hawk, was configured with Northrop Grumman’s Multi Mission Domain (MMD) architecture. MMD is an open mission system architecture for the B-2 that allows rapid and affordable fielding of modern mission capabilities. The mission transfers utilized MMD to integrate with the B-2 Adaptable Communications Suite (ACS).

In the demonstration, the aircrew received an incoming transmission from the ACS ground station, which loaded the mission directly through MMD interfaces to the B-2 Disk Drive Unit.
