Northrop Grumman Aerospace Systems posted higher sales and profits for the second quarter of 2010 due in part to increased volume on unspecified classified space programs, according to a July 29 filing with the U.S. Securities and Exchange Commission.

The Los Angeles division earned $335 million in profit on sales of $2.8 billion for the quarter that ended June 30, up 30 percent and 6 percent, respectively, compared with the same period in 2009. Sales from the company’s space systems division were up $49 million, and the company was also bolstered by stronger sales in manned and unmanned military aircraft programs.
