The U.S. Defense Department (USBODEFN)'s fiscal 2013 spending plan draws more than 40 percent of proposed reductions from weapons accounts that contribute less than a fifth of the budget, based on Pentagon projections.

The military budget that President Barack Obama will send to Congress on Feb. 13 calls for $525 billion in spending, a reduction of $45 billion from previous projections. About $18.7 billion of the cuts would come from weapons procurement, according to data provided by an official who spoke on condition of anonymity because the budget hasn't been submitted.

The breakdown shows the Pentagon is cutting weapons more deeply in an effort to limit cuts in personnel and benefits, according to Todd Harrison, a defense analyst.

"Compare that to spending on military personnel, which accounts for one-third of the budget but is only taking one- ninth of the cuts," Harrison of the Center for Strategic and Budgetary Assessments in Washington, said yesterday in an e- mail. "Protecting pay, benefits, and end strength is a higher priority than modernizing weapon systems."
