President Donald Trump is asking Congress to spend nearly $1.5 trillion on the military next year—a 43 percent increase to the Pentagon’s budget.

The White House included that massive increase in military spending in a budget request sent to Congress on Friday. It formalizes the proposal that Trump has been teasing for months. In percentage terms, it would be the largest year-over-year increase in military spending since the Korean War.

Some of the new military spending would be offset by cuts to other parts of the discretionary budget. The White House’s budget proposal would trim $73 billion from other programs. Overall, the White House’s budget envisions discretionary spending increasing from about $1.9 trillion to nearly $2.2 trillion next year.
