WASHINGTON -- Defense Secretary Robert Gates is proposing deep cuts to some big weapons programs such as the F-22 fighter jet as the Pentagon takes a hard look at how it spends money. 

Gates announced a broad range of cuts Monday to weapons spending, saying he plans to cut programs ranging from a new helicopter for the president to ending production of the $140 billion F-22 fighter jet. The Army's modernization program would be scaled back, while a new satellite system and a search-and-rescue helicopter would be cut. 

Gates says his budget will "profoundly reform" the way the Pentagon buys weapons and does business. 

To fight new threats from insurgents, Gates is proposing more funding for special forces and other tools.
