Anduril's Costa Mesa HQ is worth $400M. Its newest factory is in a Rhode Island zip code that builds submarines.

A $400M Defense Property Signal

A 634,000-square-foot campus inside a former Los Angeles Times printing plant hit the market in late June, fully occupied by one of the fastest-growing defense contractors in the country. The tenant, Anduril Industries, keeps writing the lease checks for its Costa Mesa headquarters, which packs labs, prototype manufacturing, and office space into a facility that property owners Invesco Ltd. and SteelWave LLC took a $251 million mortgage against in September. Commercial real estate loans typically cover about 65% of a property's value, which puts the campus near $400 million — a figure that would make it Southern California's largest office sale this year, easily topping the $210 million Bank of America Plaza deal that closed in June, Colliers International Group reported.

The numbers tell a compressed history. Invesco and SteelWave bought the site for $65 million in 2017, then completed extensive renovations by 2023. Now, with Anduril locked into a lease with roughly 13 years remaining, the campus functions as a bond backed by federal defense dollars. Eastdil Secured markets the asset to a narrow buyer pool: pension funds, life insurance companies, and private equity firms that underwrite net-lease properties. "It is a very unique sale as it is 100% occupied and Anduril has very good credit and long-term credit with the federal government," Stream Realty executive managing director Marty Pupil told Bloomberg Law.

What makes the listing unusual is the tenant, not the building. Orange County's defense and aerospace employment climbed 8.4% among major contractors last year, the Orange County Business Journal reports, and venture capital investment in U.S. defense-tech startups hit $11.4 billion through mid-June, more than double the same period's total in 2025, PitchBook data shows. Anduril alone raised $7.5 billion over the past year, closing a $5 billion Series H in May at a $61 billion valuation led by Thrive Capital and Andreessen Horowitz. The company still hires in Costa Mesa; the platform's board shows a Senior Systems Engineer role for Launched Effects posted there at $166,000–$220,000 per year. Yet the headquarters itself is being monetized by its landlords, not held. That distinction (owning the work versus owning the building) is where the defense-tech real estate calculus starts to shift.

From Costa Mesa to Quonset Point — A Distributed Manufacturing Pivot

Anduril is not just having a building sold in Costa Mesa. It is running a capital allocation experiment in real time, pulling back from a high-cost coastal headquarters while pouring $8.3 million into a production facility in North Kingstown, Rhode Island, purpose-built to churn out autonomous underwater vehicles at a rate no single legacy defense contractor would commit to on spec.

The Quonset Point facility held its ribbon-cutting on Aug. 25, 2025, Providence Business News reported. It spans up to 150,000 square feet and is designed to produce more than 200 Dive-LD hulls per year at full rate. That represents a meaningful jump from the 12 to 24 units Anduril can currently build at its Quincy, Massachusetts maritime engineering center, where the company will continue production until Quonset reaches operational status in early 2026. The Rhode Island Commerce Corp. approved $5.4 million in tax credits over 12 years through the Rebuild Rhode Island and Qualified Jobs Incentive programs. Anduril also hires in Quonset for roles like Senior Mechanical Manufacturing Engineer, Dive-XL, listed on Zero G Talent's board at $126,000 to $167,000 a year.

The logic is blunt. "We're out of space in terms of our ability in the Quincy facility to meet the demand that we're seeing from the Navy at present, let alone where we believe that's going in the future," Anduril chief strategy officer Chris Brose said, per Defense News. The Navy's ask was straightforward: can you scale? The Quonset bet is Anduril's answer — a facility sized for demand the company expects, not demand it has already captured.

Quonset Point is not a random zip code. The region has served as the build site for most of the U.S. Navy's crewed submarine fleet for fifty years, according to the Quonset Development Corporation. The Naval Undersea Warfare Center operates there. Electric Boat builds submarines there. Anduril's leadership described it as a "phenomenal center of undersea expertise and production" — a workforce pipeline and supplier network that Southern California's commercial real estate market cannot replicate for undersea systems.

The production targets reflect the Navy's stated appetite. The Dive-LD is a 3-ton autonomous underwater vehicle rated to 6,000 meters, capable of 7 knots and up to 10 days of autonomous deployment. Anduril designed it with a 3D-printed chassis, modular architecture, and commercial-off-the-shelf components specifically to enable manufacturing at volume. The company won an $18.6 million Navy contract through the Defense Innovation Unit's Commercial Solutions Opening process after a swim-off competition, and the Quonset facility is the vehicle (literally) for converting that contract into a production line.

Zero G Talent's board lists 245 Anduril roles added in the past week, with openings split between Quonset, Atlanta, Washington, D.C., and Costa Mesa. The geographic spread is the story. Anduril is building a distributed footprint that places manufacturing near military end-users in Rhode Island, engineering and program management in Atlanta, and policy-facing software work in Washington, while the Costa Mesa headquarters, for all its Orange County signaling, becomes a cost the company no longer wants to carry.

The $61B Series H Context — Capital Efficiency or Strategic Repositioning?

Anduril announced its $5 billion Series H round on May 13, 2026, doubling the company's valuation from $30.5 billion just eleven months earlier. Thrive Capital and Andreessen Horowitz led the round, per the company's announcement. The raise ranked among the largest private defense-tech fundings on record, and it landed at the same moment the company's Costa Mesa headquarters quietly appeared on the market — a coincidence that says more about how AI-native defense companies allocate capital than any press release does.

The financial picture behind the HQ listing is stark. Today's Startup News reported Anduril's revenue doubled to $2.25 billion in 2025, and the company nearly doubled its workforce over the same period. In March 2026, it signed a 10-year, $20 billion enterprise contract with the US Army for software and AI-backed weapons — one of the largest single awards ever made to a non-traditional defense contractor, VentureBurn found. That same month, it opened Arsenal-1, a manufacturing facility in Ohio spanning more than five million square feet, built to produce autonomous systems at consumer-electronics scale. The DoD also announced a separate agreement for more than 10,000 low-cost hypersonic missiles over three years, with Anduril working alongside CoAspire, Leidos, and Zone 5, per Today's Startup News.

CEO Brian Schimpf framed the Series H as fuel for manufacturing expansion and R&D. "This financing gives us the ability to continue investing aggressively in manufacturing capacity, research and development, and the infrastructure required to build and field advanced defense systems at scale," he said in a company statement. The $400 million Costa Mesa sale fits that framing: a company sitting on $61 billion in paper value and $2.25 billion in annual revenue has no reason to own a building it can lease back. Selling the property converts a non-core asset into deployable capital without disrupting operations — the campus remains fully leased to Anduril.

But the move also signals something less comfortable for the "defense-tech campus" narrative that Orange County has been selling itself on. Anduril's hiring data tells the story. The company added 245 roles in the past week alone on that platform. The Costa Mesa posting is for the same senior systems engineer role for launched effects. The bulk of new positions — manufacturing development in Atlanta, production program managers, mechanical engineers for the Dive-XL autonomous submarine in Quonset, Rhode Island — are production and hardware roles anchored to facilities that sit close to military test ranges and end-users, not to a coastal headquarters designed for investor meetings and recruiting events.

The $61 billion valuation gives Anduril the balance sheet to do both: keep the Costa Mesa lease for customer-facing work while routing capital into Arsenal-1, Quonset Point, and the hypersonic missile production line. Whether that constitutes capital discipline or a strategic bet against the centralized defense-tech campus model depends on what happens next. If the Costa Mesa sale closes at or near its estimated price and Anduril redirects even a fraction of that sum into Quonset Point production scaling, the answer is both — and the defense-real estate arbitrage becomes a template other well-funded startups will follow.

California Defense-Tech Evolution, Not Exodus

The easy narrative is that Anduril is fleeing California. The harder truth is that the company is doing something more surgical — and more telling about where defense tech actually builds things versus where it sells them.

Anduril still lists open roles in Costa Mesa, including a Senior Systems Engineer for its Launched Effects product line. That's not the footprint of a company pulling out of Orange County. It's the footprint of a company keeping a West Coast sales and business development node while moving the physical work (manufacturing, integration, test) to sites closer to the military customers buying the hardware. The Costa Mesa listing isn't an exit. It's a reclassification of what a defense-tech headquarters is for.

That distinction matters because the broader California defense-tech picture is more mixed than the "exodus" framing suggests. Zero G Talent's board shows Anduril adding roles in four states over the past week alone (Georgia, Rhode Island, D.C., and California) which reads less like a retreat and more like a deliberate distribution of functions across geographies. The company isn't shrinking its California presence so much as it's refusing to let a single coastal property define its operational identity.

Orange County's defense-property market reflects this tension. The region still concentrates a dense cluster of defense contractors, aerospace suppliers, and systems integrators — companies that need proximity to Navy installations, Air Force test ranges, and the Southern California supply chain that supports both. But the nature of that presence is shifting. The companies growing fastest in the region are increasingly software-heavy, AI-native firms that don't need the sprawling manufacturing floors legacy contractors relied on. They need office space, compute infrastructure, and access to engineering talent. A headquarters building designed for a different era of defense work becomes a cost center rather than a strategic asset.

This is the maturation pattern. When a defense-tech sector moves from hardware-centric to software-centric, the real estate logic inverts. Legacy firms built campuses to house production. Newer firms like Anduril build campuses to house recruiting — a physical signal to engineers that the company is established, permanent, and well-funded. Once that recruiting function is served and the production work migrates to purpose-built facilities near military end-users, the headquarters becomes negotiable. Selling it isn't distress. It's portfolio management.

The question for Orange County isn't whether defense tech is leaving. It's whether the next generation of companies will ever build the kind of physical footprint that the last generation did — or whether they'll follow Anduril's model of distributed production, lean coastal offices, and real estate treated as a line item to be optimized rather than a monument to be maintained.

The Broader Defense-Tech Real Estate Arbitrage

Anduril's Costa Mesa HQ listing is not an isolated data point. It is the most visible transaction in a sector-wide restructuring of how defense-tech companies occupy physical space, one that is creating a new arbitrage between high-cost coastal headquarters and production facilities positioned near military end-users. The pattern is spreading across the industry, and the numbers behind it are substantial.

Consider the broader financial context. 1789 Capital, the venture firm co-founded by Omeed Malik and Chris Buskirk with Donald Trump Jr. as a partner, has swelled from roughly $200 million in assets to $2 billion in a single year, Fox Business reports. The firm was an early Anduril backer and has since deployed capital across a portfolio that includes SpaceX, Groq, and GrabAGun, per Wikipedia. In September 2025, Bloomberg reported that 1789 Capital was lining up $1 billion in investor interest for a new real estate fund focused on South Florida. The fund's thesis: capitalize on migration from high-tax states like New York to Southern Florida, which has fueled demand for commercial space, housing, hospitals, and schools. That is a real estate play built on the same logic that is reshaping defense-tech footprints — capital flowing out of expensive coastal markets and into production-oriented regions.

The defense sector's real estate strategy is increasingly bifurcated. Companies maintain a token presence in coastal innovation hubs (Costa Mesa, San Diego, Boston) while routing actual manufacturing and production hiring to facilities near military installations and test ranges. COPT Defense Properties, a publicly traded REIT, has built an entire business model around owning and operating mission-critical facilities adjacent to U.S. government defense installations. The company's portfolio concentrates in Maryland, Washington D.C., Virginia, and Alabama — not in the coastal tech corridors where defense startups announce their fundings. COPT's pitch to investors is explicit: it provides secure, hi-tech space for defense contractors executing priority missions, proximate to the military facilities that are their actual customers.

The Department of Defense's own AI strategy documents reinforce the trend. The Pentagon's artificial intelligence strategy emphasizes AI-enabled capability development that will "redefine the character of military affairs over the next decade," per the Department of Defense. The manufacturing base needed to build that capability (autonomous systems, drones, AI-integrated hardware) requires production facilities with access to military test ranges, secure communications infrastructure, and a workforce cleared for classified programs. Costa Mesa offers none of those things. Quonset Point offers all of them.

The result is a property market that is segmenting in real time. Orange County's defense-tech real estate values are being driven up by the same coastal amenities that attract software companies and venture capital offices. But the actual production work (the hiring, the manufacturing, the contract fulfillment) is migrating to regions where the military already has a footprint. Anduril's $400M Costa Mesa listing is the premium someone is willing to pay for the coastal address. The question is whether that premium reflects the value of the location for defense-tech production, or simply the value of the real estate as a coastal asset in a market that still prices location over function.

The answer, based on where Anduril is actually hiring, is the latter. The company is not selling its Costa Mesa lease because the facility failed. It is selling because the facility's highest-value use (as coastal real estate in a supply-constrained Orange County market) no longer aligns with its operational needs. The production roles that drive revenue and contract fulfillment are in Atlanta and Quonset Point. The Costa Mesa space served a different era of defense-tech company-building, one modeled on the Silicon Valley startup playbook of coastal campuses and open floor plans.

That era is ending. The defense-tech companies scaling now (Anduril, Palantir, Hadrian, Firehawk Aerospace) are building for production, not for pitch decks. Their real estate strategies reflect that shift. And the arbitrage between coastal headquarters valuations and the cost of production facilities near military end-users is only going to widen as the Pentagon's AI and autonomous systems procurement accelerates. The next defense-tech company to list its coastal HQ for sale will not be the last.
