The top tier of federal contractors has remained remarkably consistent for the last decade. Lockheed has long been number one, billions of dollars ahead of perennial runner-up Boeing, which is closely followed by Northrop, General Dynamics, and Raytheon. The rest of the top ten is rounded out every year by United Technologies, L-3, SAIC, BAE Systems, and KBR . The Wisconsin-based truck manufacturer Oshkosh Corporation is a relatively new member of the contracting elite, having been catapulted into top ten a couple years ago as the result of scoring some very lucrative deals to build vehicles for the military.

Lockheed alone accounted for six percent of the FY2010 total. In fact, the top 100 contractors will, in any given year, account for about half of all federal contract spending. Looking at this another way, 50 percent of the contracts go to just .03 percent the contractors.

POGO's advice to deficit hawks looking for ways to cut government waste: Forget about pulling the plug on a website dedicated to the endangered Desert Tortoise: open up the federal contracting money vault, and take it from the top! For that matter, don't be stingy about clawing back some of that money from the other 299,000 or so other contractors.
