Former President Donald Trump has advocated for a significant increase in US defense spending, proposing to raise it to $1.5 trillion by 2027, a more than 50% jump from the current budget. He also threatened to crack down on defense contractors for slow deliveries and urged them to build new manufacturing plants.

• Proposed defense budget: $1.5 trillion (£1.1tn) by 2027, more than 50% higher than the current $901 billion budget.
• Key person involved: Donald Trump, former President of the United States.
• Notable detail: Trump criticized Raytheon as "the least responsive" and threatened to end their business with the Department of War if they don't invest more in production capabilities.
