Fortastra Raises $30M for Orbital Security Spacecraft

Sahil Desai is asking Fortastra's engineers to design the production architecture while they prototype the next spacecraft. For a company building vehicles to operate close to valuable satellites, that choice connects two demanding jobs: making the vehicle work in orbit and making its successors practical to build.

Fortastra, headquartered in Torrance, California, closed a $30M Series A on October 8, 2026. First In led the financing, joined by Upfront Ventures, Space Capital, Rsquared, Side Door Ventures, ATX Ventures, and other new and existing investors. The capital will support spacecraft development, engineering and operations hiring, autonomy, and manufacturing expansion.

Fortastra's proposition is physical protection for infrastructure already in space. The company designs maneuverable spacecraft intended to remain near critical assets, assess nearby activity, and respond to potential threats. Its financing gives a young orbital-defense business more resources to connect navigation, perception, vehicle design, and repeatable production.

What Fortastra's Series A finances

Fortastra plans to develop and commission its on-orbit security platforms while expanding the engineering organization around them. Flight software, guidance, navigation and control, and autonomy are named priorities. The spacecraft bus, the underlying vehicle platform carrying mission systems, is being designed for cost-conscious manufacturing at higher rates.

CTO Josh Jetter describes proximity operations as a prerequisite for the company's other capabilities. A spacecraft working near another asset needs to establish relative position, interpret what its sensors detect, and execute controlled maneuvers. These functions have to operate as a coherent vehicle rather than as separate accomplishments in a laboratory.

Desai, Fortastra's VP of Product, says the next spacecraft and its production architecture will be developed in parallel. That approach brings manufacturing decisions into the period when engineering choices can still change. A component's geometry, the way it is assembled, and the tests needed to qualify it can all affect how readily a design moves from one vehicle to several.

The commercial implication is straightforward: a protection system's availability depends partly on how many vehicles its supplier can deliver. Fortastra has not disclosed production cadence or unit economics. Those missing numbers keep the Series A focused on the work being financed, while the company's proposed scale remains an operating objective.

From founder experience to an orbital mission

Founder and CEO Mike Smayda brings experience from launch vehicles and high-speed aircraft. Fortastra's December 2025 public debut identifies his prior work as a senior aerodynamics engineer at SpaceX, including contributions to the reusable Falcon 9 first stage, and his role as co-founder and CPO of Hermeus. Fortastra was founded in 2025.

That history places the new company at another consequential point in a space mission. Launch delivers an asset into its operating environment; Fortastra is working on the security services that asset may need once it arrives. The company's immediate focus is national security, with potential commercial and civil applications described by management as a later opportunity.

Fortastra says it progressed from seed funding to orbit in about a year and reports initial operational success with Watchdog V0. The company also says it has secured initial government contracts. Publicly reviewed materials do not establish contract values, named customers, or a detailed independent assessment of defensive mission performance, so the milestones remain attributed company statements.

The funding history requires similar care. Fortastra's December 2025 announcement reported more than $8M in seed financing led by Upfront Ventures, with Generational Partners, Wave Function Ventures, Bloomberg Beta, and Forward Deployed VC participating. Added to the new Series A, the disclosed rounds exceed $38M; that is a lower bound calculated from the announcements, rather than a separately disclosed exact lifetime total. The Series A valuation was not announced.

Manufacturing enters the spacecraft design process

Fortastra's memorandum of understanding with Hadrian gives the production discussion a specific industrial relationship. In a direct interview with TCT, Desai and Hadrian VP of Additive Manufacturing Matthew Parker described bringing their engineering teams together around spacecraft requirements and manufacturing capabilities. The collaboration is intended to examine how advanced manufacturing can support development.

Precision machining and additive manufacturing offer different ways to make components, but selecting a process does not finish the qualification work. Space hardware must survive its intended environment, and manufacturing changes have to preserve the properties the design depends on. Fortastra contributes spaceflight qualification experience to a relationship that also gives Hadrian an early view of customer needs.

The MOU is a framework for technical collaboration, with design reviews and manufacturing assessment among its stated activities. It should not be read as a disclosed order for a specified number of spacecraft. Its relevance to the Series A is that Fortastra is addressing the production process before presenting high-rate manufacture as an accomplished fact.

For buyers evaluating an orbital security supplier, the engineering and industrial questions travel together. Vehicle maneuverability matters alongside qualification, manufacturing consistency, and the ability to support repeated missions. Fortastra is directing capital toward those connections, where software decisions meet hardware that must be built, tested, and flown.

The security coverage First In is backing

First In's investment places orbital protection within a broader security-technology mandate. The firm's General Partner Arthur Karell leads investments spanning defense and dual-use technologies, AI, industrial automation, and digital asset security. In Fortastra's announcement, Karell connects the importance of space assets with the case for defenses that can be deployed in numbers.

That creates an economic relationship between vehicle cost and coverage. A fleet designed to protect multiple assets or operate across orbital environments asks more of production than a single demonstration. Fortastra's ambition for persistent, multi-orbit security depends on making vehicles repeatable as well as capable; the announcement supplies the financing and development plan for that ambition, rather than a current fleet-coverage figure.

The company's current careers page makes the staffing needs concrete, listing work across guidance and control, autonomy, perception, flight and ground software, avionics, and mechanical and propulsion engineering. These roles reflect the breadth of the system Fortastra is assembling. They also give potential hires a clearer picture of the work than a general promise to grow a defense startup.

Smayda, Jetter, and Desai now have additional capital to carry Watchdog's early flight experience into the next vehicle and its manufacturing process. Each design decision will reach beyond the prototype on the bench, into the tests, suppliers, and assembly work needed for the spacecraft that follows it.
