The Washington Post reports yesterday on cost overruns for weapons procurement. "It is not unusual for weapons programs to go 20 to 50 percent over budget, the Government Accountability Office found."
That’s for sure. As I’ve documented, it’s not unusual for weapons to more than double in cost. I’m talking about the F/A-22 Raptor, the V-22 Osprey, the CH-47F helicopter, the Patriot missile, and on and on. See here, and see the discussion in Downsizing the Federal Government.
The same pattern occurs in federal highway projects, energy projects, and many other government endeavors.
Part of the reason this occurs is that contractors and government officials have a quiet understanding that the initial cost numbers that are used to get projects launched should be low-balled. Both sides know that later on, after projects are underway, excuses can be found to raise the price tag. "The scope of work has expanded." "We couldn’t have foreseen those additional problems." "The mission requirements have changed." "There are new regulatory requirements."
