President Barack Obama on Monday asked Congress to approve a record $708 billion in defense spending for fiscal year 2011, including a 3.4 percent increase in the Pentagon’s base budget and $159 billion to fund U.S. military missions in Iraq, Afghanistan and Pakistan.

The White House budget request also included $33 billion in additional funding for fiscal 2010 to pay for increasing military and intelligence operations in Afghanistan and Pakistan, and drawing down U.S. forces in Iraq. That comes on top of $129.6 billion already provided for the current fiscal year, which ends September 30.

The Pentagon’s base budget request of $549 billion is up $18 billion from $531 billion in fiscal 2010, and will pay for continued reforms of defense acquisitions, development of a ballistic missile defense system and care of wounded soldiers.

The budget also calls for cancellation of several major weapons programs, including Boeing Co’s C-17 transport plane, saving $2.5 billion, and a second engine for the Lockheed Martin Corp F-35 fighter jet, saving $465 million in fiscal 2011 and more than $1 billion longer-term. The White House tried to kill both programs last year, but lawmakers revived them during the budget process.
