The Obama administration will propose a defense spending increase to levels not seen since 2012 when it sends Congress a $585 billion Pentagon budget request on Monday.

The plan, like others submitted in recent years, will ignore federal spending caps by $34 billion in 2016 and $150 billion over the next five years, according to a source with knowledge of the proposal.

The budget will include $5.3 billion to continue airstrikes against Islamic State militants in Iraq and Syria, of which $1.3 billion is for training Iraqi Security Forces and moderate Syrian rebels. It also includes $42.5 billion for U.S. operations in Afghanistan next year – less than the $53.4 appropriated for fiscal 2015 – as the number of American forces is expected to decline below the roughly 10,000 soldiers there today.
