Space-related sales at Northrop Grumman Aerospace Systems rose by $201 million as increased volume on a classified satellite contract awarded a year earlier offset the cancellation of the U.S. Air Force’s Transformational Satellite (T-Sat) communications program and reduced revenue from the National Polar-orbiting Operational Environmental Satellite System (NPOESS), the company said.

In a Feb. 4 filing with the U.S. Securities and Exchange Commission, Northrop Grumman Corp. said its Aerospace Systems Division, which makes satellites and aircraft, increased its revenue by 6 percent to $10.4 billion in 2009, and more than doubled its profit — to $1.1 billion. Northrop Grumman was a major subcontractor on the T-Sat program and is prime contractor on NPOESS, now slated for a restructuring that leaves the company’s future role uncertain.

Northrop Grumman Electronic Systems, meanwhile, saw revenue increased by 9 percent to $7.7 billion in 2009, driven in part by increased volume on its Space Based Infrared System payload work. The division’s profit was up slightly to $969 million for the year, the filing said.

Overall, Los Angeles-based Northrop Grumman reported revenue of $31 billion, up 2 percent from 2008, and operating income of $2.5 billion. The company lost $263 million in 2008.
