FOSSA Systems: A Spanish Satellite Startup’s Bold Leap into Defense
A Spanish satellite startup, FOSSA Systems, is making waves in the aerospace industry by transitioning from building tiny spacecraft for under $30,000 to pursuing defense contracts in Tokyo. This strategic pivot aims to capitalize on the growing demand for sovereign space capabilities among government customers, particularly in Japan.
Expanding Horizons: The Tokyo Office
FOSSA has recently opened its first office outside Europe in Tokyo, partnering with the Japanese trading firm Kanematsu. This move positions the company to tap into Japan’s expanding defense and national security market. Since pivoting from sub-kilogram picosatellites in 2023, FOSSA has reported significant revenue growth and is now scaling up to larger microsatellites. These new platforms will focus on signals intelligence and secure communications, appealing directly to military needs.
From Picosatellites to Microsatellites
FOSSA’s journey began with the deployment of multiple picosatellites, each weighing less than a kilogram. These tiny spacecraft were developed quickly and at a low cost, proving FOSSA’s ability to deliver hardware to orbit efficiently. However, the limitations of picosatellites became apparent when it came to securing defense contracts.
In 2023, the company shifted its focus to larger 3U cubesats, which offer extended operational lifespans and improved capabilities. FOSSA currently operates several 3U cubesats and has recently launched a 6U cubesat aboard a SpaceX rocket. Yet, even these larger satellites have their constraints. The planned microsatellites represent a significant leap in capability, making FOSSA more attractive to military planners who prioritize data rates, revisit times, and payload capacities.
Financial Growth and Market Response
FOSSA’s financial trajectory reflects a positive market response to its pivot. The company has expanded its workforce to around 50 employees since the transition and raised €6.3 million ($7 million) in a Series A funding round in 2024. While this amount may seem modest in the space industry, where missions can cost tens of millions, it highlights FOSSA’s vertically integrated approach. By building its own satellites, ground stations, and user terminals, the company keeps per-unit costs lower than competitors reliant on third-party suppliers.
However, sustaining this growth will be a challenge as FOSSA enters the defense market, where procurement cycles are longer and qualification requirements are more stringent than those for commercial IoT customers. Current data rates are suitable for IoT telemetry and basic sensor data but fall short for the bandwidth-intensive applications expected by defense users.
Japan’s Strategic Defense Landscape
Japan’s recent re-evaluation of its defense posture has led to increased spending and a more assertive approach to space capabilities. Surrounded by water and facing potential threats from North Korea and China, Japan prioritizes satellite-based maritime surveillance and communications. FOSSA’s existing IoT connectivity has maritime applications, and its partnership with Kanematsu provides a credible local presence, essential for navigating Japan’s complex defense procurement landscape.
Moreover, Japan represents a strategic choice for FOSSA due to its relatively thin competition in the cubesat-to-microsatellite range. With fewer domestic alternatives and a growing appetite for allied technology, Japan offers a fertile ground for FOSSA’s ambitions.
Institutional Credibility through NATO
FOSSA’s acceptance into NATO’s Defence Innovation Accelerator for the North Atlantic (DIANA) adds a layer of institutional credibility that is crucial for attracting government customers. DIANA aims to source future military capabilities from dual-use commercial innovators and provides access to funding, accelerator sites, and test centers for technology demonstrations.
Being part of DIANA signals to defense procurement officials that FOSSA has passed an initial screening for military relevance, which can significantly enhance its chances of securing contracts. This is particularly important as Western defense establishments grapple with integrating commercial space capabilities into their acquisition pipelines.
The Ambitious Constellation Plan
FOSSA has ambitious plans to establish a full constellation of microsatellites within the next few years. However, this raises questions about financing such an extensive buildout. A large constellation requires significant capital for manufacturing, launch services, and ground operations. While FOSSA’s vertical integration model helps manage costs, running multiple hardware businesses simultaneously presents its own set of challenges.
Navigating a Crowded Market
The small satellite defense market is becoming increasingly competitive, with established players like BlackSky, Capella Space, and HawkEye 360 already providing various satellite-based intelligence solutions to government customers. FOSSA’s unique selling proposition lies in its cost-effectiveness. With a history of building spacecraft for under $30,000, the company aims to deliver valuable defense capabilities at a fraction of the cost of traditional defense satellite programs.
This cost advantage is particularly appealing to mid-tier military powers in Europe and the Asia-Pacific region, which are looking to enhance their space-based situational awareness without the hefty price tags associated with custom-built national constellations.
The Road Ahead
FOSSA has demonstrated its ability to build and launch small satellites quickly, along with impressive revenue growth and international expansion. However, the real test lies in its capacity to develop larger, more capable platforms that meet the stringent requirements of defense customers.
As the company navigates this complex landscape, the actions of its partner Kanematsu will be closely watched. Japanese trading houses typically do not partner with foreign startups lightly, and a deepening relationship could indicate that FOSSA’s defense pitch is resonating with key decision-makers in Japan’s defense sector.
The coming years will be pivotal for FOSSA Systems as it seeks to establish itself as a formidable player in the defense satellite market, balancing ambition with the realities of capital and competition.
