Tom Barnett predicts Lockheed's future

Tom Barnett is pushing the theory that Lockheed Martin's IT and infrastructure unit -- dubbed IS&GS -- will overtake aeronautics as the company's biggest cash cow. He writes:

IS & GS doesn't build any platforms in a conventional sense, just IT platforms and services and systems integration, and already it's the biggest source of revenue of the biggest defense corporation in the world.

Sign of the times and and the world.

Hold on, Mr. Barnett. 1) IT is probably the most vulnerable sector in the defense market to spending cuts in a downturn; 2) Aeronautics is now in a six-month transition, but could come storming back next year (think new orders for C-130J, F-16, F-22, F-35).
