Northrop Grumman Offers Price for More B-2s: The Los Angeles-based defense contractor formally offered to sell the government 20 more B-2 bombers for a fixed price of $11.4 billion in the company’s latest effort to save its major weapons program from extinction. Northrop hopes the Republican takeover of Congress will reverse years of legislative opposition to the “stealth� bomber just as the 20th and final bat-winged plane nears completion in Palmdale. Northrop’s figures differ sharply from those in a Congressional Budget Office study saying 20 more B-2s would cost $26 billion. The Pentagon last summer put the cost at $20 billion.
