The Southern California Space Tech Cluster: Growth Prospects And Challenges

By Christopher Lynch, President, International Business Accelerator (IBA)

In less than ten years, Southern California (from Santa Barbara through Los Angeles, Orange County to San Diego) has emerged as the center of gravity in global Space Tech development. With commercialization costs dropping (function of reusability, low-cost prototyping and new designs), the SoCal Space Tech Cluster is poised for sustained growth with a strong advanced manufacturing base, skilled workforce and top-rated research universities. On the flip side, the cluster is constrained by the high cost of doing business in California.

DEVELOPMENT OF THE SOCAL SPACE TECH CLUSTER

What makes the SoCal Space Tech cluster so unique? The SoCal Space Tech cluster builds on an earlier cluster – civil and defense aviation from the 1950s through the 1990s. Los Angeles manufactured not only aircraft but also components NASA through the moon missions. However, rising production costs resulted in aircraft assembly moving elsewhere. Two critical elements remained — strong academic institutions and defense contracts for satellites.

When Elon Musk founded SpaceX in 2002, the foundation for the Space Tech cluster was already in place. The struggles and successes of SpaceX are well documented, but Musk had a strategy of growing the company from within. I visited SpaceX in Hawthorne in 2019 and was struck by the young, enthusiastic work force. I asked if SpaceX had hired many of the former engineers and assembly workers from McDonnel-Douglas and Boeing, but I was told the company did not. Instead, SpaceX hired younger workers, fluent in the digital age, many of whom had non-technical backgrounds.

The cluster took off as space commercialization became a reality, starting with SpaceX’s demonstrated capability to reuse launch vehicles.

• Rocket Lab moved from New Zealand to Long Beach in 2013. In 2024, Rocket Lab CFO Adam Spice described the difficult decision very simply, “We had to be where the talent was.”
• In 2015, Relativity Space launched with its own mission. Both companies have focused on the smaller range of launch vehicles but are developing payloads designed for the commercial market.
• 2017 also marked the founding of Anduril Industries in Orange County. The company has been known for its low-cost approach to building drones and defense technologies. The company is space-tech adjacent but represents the opportunities for cost reduction as products move from one-offs to mass production.
• In 2021, Vast Space started in Long Beach with the mission to create private sector space stations. The company goal is straightforward: “Vast is developing next-generation space stations and space infrastructure using an incremental, hardware-rich and low-cost approach.”

There are literally hundreds of law firms (especially IP and contracts), accounting, HR, logistics and financial services providers that offer products tailored to Space Tech clients.  

STRENGTHS AND WEAKNESSES OF THE SOCAL SPACE TECH CLUSTER

Strength: Advanced Manufacturing Hub of the US

What may surprise many outsiders is that Southern California leads the country in manufacturing. LA County alone has output of over $190 billion annually, led by the largest concentration of advanced manufacturing facilities in the US. Those companies have deep expertise in composites, propulsion, avionics, and precision machining.

In the Space Tech sector, Southern California has legacy infrastructure from Boeing, Northrop, Lockheed, and Raytheon combined with manufacturing advances from SpaceX, Rocket Lab, and emerging startups. Space technology is hardware‑intensive, and this mix allows for rapid prototyping and access to specialized materials. test stands, integration facilities and environmental testing facilities.

Strength: Skilled Workforce

Perhaps the greatest strength of the cluster is in the skilled workforce. There are an estimated 45,000+ aerospace jobs in LA County alone. In addition to workers trained in advanced manufacturing, companies can tap into extensive engineering talent pool. There are around 7,000 aerospace engineers in the SoCal region. Local universities graduate 6,800 engineers of all stripes each year, the highest in the US.

Strength: Academic Anchors Supporting Innovation

One of the key pillars of all successful clusters is research universities to support the innovation pipeline. Southern California has arguably the best base in the world.

• Caltech: among the highest per‑capita production of aerospace PhDs globally; direct pipeline into JPL and propulsion startups.
• USC: one of the largest aerospace engineering programs in the U.S.; strong ties to SpaceX and Anduril.
• UCLA: leading programs in autonomy, robotics, and materials science.
• UC Irvine: growing strengths in propulsion, advanced manufacturing, and materials engineering.

California generates roughly 40% of U.S. space‑technology patents (USPTO data) and LA County alone received $315 million in DARPA contracts. There are no breakdowns below the state level, but California received more than 20% of all SBIR awards in 2025.

Weakness: High Cost of Doing Business in Southern California

California is an expensive place to do business. Part is due to regulation (everything from employment law to permits). That trickles down to workers who are concerned about being priced out of the housing market. Elected officials are aware of these concerns — whether changes are made remains to be seen. At this point in time, the advantages listed above seem to outweigh the costs. The cautionary tale is that the aerospace cluster dried up as innovation slowed and companies moved labor-intensive operations to cheaper locations.
