President Joe Biden's U.S. defense and national security budget request is 1% higher than last year, causing a slowdown in spending on various programs and delaying efforts to rebuild weapons stocks. The $895 billion budget request includes funds for homeland security and nuclear weapons-related activities by the Department of Energy. Under the cap, the Pentagon's share of the national defense budget is $850 billion, which will curb purchases of the stealthy F-35 jet and air defenses for Guam.
