The U.S. Air Force said that it awarded Northrop Grumman Corp. an $89.7 million contract modification for operation and support of its BACN electronics.

BACN, pronounced “bacon,” stands for Battlefield Airborne Communications Node. It is essentially an Internet server and communications relay flown above a battlefield, or an area hit by a natural disaster. BACN links various systems that wouldn’t normally communicate among themselves. The Air Force has four manned aircraft and three unmanned aircraft carrying the BACN electronics.

The contract modification pays for staff, facilities and supplies to support operations through June 2015. The total cumulative face value of the contract is $1.21 billion. The Air Force Life Cycle Management Center at Hanscom Air Force Base, Mass. awarded the deal.
