Summary

The business of military contracting in Southern California is booming, with defense contracts won by companies in Los Angeles County more than doubling in value over the last 10 years. According to an analysis by The Markup and CalMatters, the total value of these contracts rose from $6 billion in 2010 to $15 billion in 2025, adjusted for inflation. The increase is attributed in part to a surge of venture capital investment in aerospace and defense companies, with many startups claiming a growing share of the pie. This has led to concerns about privatization and the risk of a space arms race, with some Congressional Democrats pushing back against the increased military spending.

Story summary

In Southern California, the value of military contracts won by companies in Los Angeles County has more than doubled over the past decade to $15 billion, despite accounting for inflation. This boom is partly driven by an increase in startups, including those valued at over $1 billion, that are developing defense systems such as low-cost missiles and drones. Companies like Boeing, with headquarters elsewhere, have also received a large share of contracts. The growth in military contracting comes as the US Defense Department has announced plans to invest in new technologies, including a proposed "Golden Dome" missile-defense system** that could cost hundreds of billions of dollars.

Narrative

When Defense Secretary Pete Hegseth recently went on tour to promote the “Arsenal of Freedom,” a plan to massively increase munitions building, he told the workers at a Long Beach company, Rocket Lab, that “dominance of space” was key to the military’s future. “This company, you right here, are front and center, as part of ensuring that we build an arsenal of freedom that America needs,” he said.
