The Department of Defense needs to increase its defense spending significantly to meet current and future global threats, according to a new plan from Sen. Roger Wicker (R-MS), the ranking member of the Senate Armed Services Committee.

The senator argues that the U.S. defense industrial base is underfunded and unprepared for future conflict, and in order to correct this course of action, the annual defense budget should grow to 5% of the U.S. gross domestic product. The current figure is around 3%.
