The Zero AIDepartment of Defense's proposed budget for 2024 is $842 billion. That is about 3.5% of the U.S.'s GDP. The military buys everything from pens and paper clips to fighter jets and submarines. But the market for military equipment is very different from the commercial market.

On today's episode, we're bringing you two stories from The Indicator's series on defense spending that explore that market. As the U.S. continues to send weapons to Ukraine and Israel, we first look at why defense costs are getting so high. Then, we dive into whether bare-bones manufacturing styles are leaving the U.S. military in a bind.

The original Indicator episodes were produced by Cooper Katz McKim with engineering from Maggie Luthar and James Willetts. It was fact-checked by Sierra Juarez and Angel Carreras. They were edited by Kate Concannon and Paddy Hirsch. Alex Goldmark is Planet Money's executive producer.
