Southern California is rapidly emerging as a leading hub for advanced industrial tech manufacturing, especially in the aerospace and defense sectors. This resurgence is fueled by substantial government contracts, with Los Angeles County alone receiving an estimated $7 billion in major aerospace and defense contracts in the past six months, including $1.6 billion for Space Force satellite contracts supporting Rocket Lab and Northrop Grumman, a $2.39 billion NASA agreement for JPL, and over $2.14 billion for SpaceX. In 2025, Los Angeles County secured the most direct Department of Defense contracts in the U.S., totaling $8.9 billion in federal funding, which has spurred the growth of numerous startups and defense companies.
The region's robust industrial ecosystem, including manufacturing, warehousing, and distribution, supports approximately 1.5 million jobs across Los Angeles, Orange, Riverside, and San Bernardino counties, contributing about 11% to the region's GDP. California maintains its position as America's largest manufacturing state by workforce, with roughly 1.2 million manufacturing jobs and a $390 billion manufacturing GDP in 2025. This growth is attracting significant venture capital, with more than $14.6 billion invested in military, national security, and law enforcement categories by mid-2026, surpassing the total $9.6 billion for all of 2025. Companies like Hadrian raised $1.7 billion in a Series D round, and Amca achieved unicorn status with a valuation over $1 billion after raising $300 million in Series B funding.
The demand for specialized manufacturing space in Southern California, particularly in the South Bay cities like Torrance, Hawthorne, Long Beach, and El Segundo, is four times the current supply. This has led to a surge in industrial real estate activity, with the Los Angeles industrial market recording 2.8 million square feet of net absorption in the second quarter of 2026, nearly tripling the previous quarter's rate. Major deals include Valar Atomics' 512,000-square-foot lease in Torrance, Divergent Tech's 415,000-square-foot lease in Long Beach, and Hermeus's relocation from Atlanta to El Segundo. Anduril also committed to a $1 billion, nearly 1.2 million-square-foot campus in Long Beach. The unique talent pool is cited as a primary reason why startups choose to establish their headquarters in Southern California, despite the perception of high costs and regulations.
Aerospace and defense leasing in Los Angeles County has quintupled its share of big-box industrial activity since 2025, now accounting for 11% compared to 2% between 2015 and 2024. This surge has revitalized the industrial market, with the county's vacancy rate dropping to 5.1% in the second quarter from 6.4% a year prior. Rents have also increased, with prime industrial areas like the South Bay seeing rents of $1.60 per square foot. The region's extensive infrastructure, including the ports of Los Angeles and Long Beach, as well as rail, highway, and air cargo networks, further enhances its appeal for combining domestic production with global supply chain access.
