Quantum Systems and XTEND are expanding the software layer connecting autonomous defense systems, announcing a partnership that integrates XTEND’s XOS operating system and autonomous mission capabilities into Quantum Systems’ MOSAIC UXS ecosystem. The collaboration targets defense, homeland security and public-safety customers as NATO allies accelerate spending on autonomous systems, emerging technologies and defense-industrial capacity.
The defense industry is moving toward a model in which drones, sensors, robotic platforms and mission software operate as interconnected systems rather than isolated pieces of hardware.
Quantum Systems and XTEND are betting that software interoperability will become a critical part of that transition.
The companies announced a partnership on September 10 to develop and deliver integrated autonomous mission solutions for defense, homeland security and public-safety customers. The agreement expands Quantum Systems’ MOSAIC UXS mission software ecosystem by integrating XTEND’s autonomous systems and XOS operating system.
The companies say the integration is designed to support interoperable missions spanning sensing, swarming and strike while giving operators a common operational environment.
The significance is less about another autonomous platform entering the market and more about the software architecture sitting between multiple platforms.
Modern defense forces increasingly operate heterogeneous fleets. A mission may involve intelligence-gathering drones, autonomous aerial systems, ground robots and other effectors supplied by different vendors. If each system requires its own control interface, data architecture and operator training, adding more autonomous assets can also increase operational complexity.
MOSAIC UXS and XOS are intended to address that problem from complementary positions.
Quantum Systems brings expertise in autonomous intelligence collection and its mission-software environment, while XTEND contributes an operating system designed to coordinate autonomous robotic capabilities.
The companies say the combined architecture should allow different autonomous systems to operate within one environment and help new operators become mission-ready within days.
That claim will ultimately depend on deployment conditions, integration depth and the degree of interoperability achieved across actual customer systems. Nevertheless, the underlying direction aligns with a broader shift in defense procurement toward open architectures, software-defined capabilities and rapidly deployable autonomous systems.
The partnership is already supporting a joint autonomous-systems program for a European NATO customer, with additional customer programs and demonstrations planned for 2026 and beyond.
Defense Spending Creates a Larger Market for Autonomy
The commercial backdrop is unusually strong.
At the 2025 NATO Summit in The Hague, member states committed to reaching 5% of GDP annually on defense by 2035. The commitment includes at least 3.5% for core defense requirements and up to 1.5% for defense- and security-related investment, including critical infrastructure, resilience, innovation and strengthening the defense industrial base.
NATO says European Allies and Canada increased defense expenditure by more than $90 billion in 2025, measured in 2021 prices, bringing combined spending above $571 billion.
The alliance is also explicitly emphasizing emerging technology and faster adoption. NATO’s post-Hague agenda includes measures intended to increase defense-industrial production and accelerate the integration of new technologies.
That environment creates opportunities for companies building autonomous systems, but it also changes what governments may expect from those vendors.
A procurement decision increasingly has to consider not only whether an individual drone or robot performs its mission, but whether it can integrate into an existing digital and operational architecture.
From Drone Platforms to Autonomous Mission Networks
The strategic shift is important.
For years, much of the commercial autonomous-systems market was organized around individual platforms: a drone for surveillance, another system for logistics, or a robotic vehicle for a specific ground mission.
The emerging model is closer to an autonomous mission network.
In that model, sensors generate data, software determines what information matters, autonomous systems perform assigned tasks and human operators supervise or intervene when necessary.
Quantum Systems’ MOSAIC UXS is positioned as the connective software layer in that architecture, while XTEND’s XOS provides the autonomous operating environment on its side of the integration.
The companies’ reference to workflows spanning sensing, swarming and strike also signals an attempt to connect the full operational chain rather than simply integrate two individual vehicles.
For defense customers, the potential benefit is flexibility.
An architecture that can accommodate different autonomous assets can theoretically reduce dependence on a single platform manufacturer and allow militaries to introduce new capabilities without rebuilding their entire mission-control environment.
That is particularly relevant as autonomous technology develops faster than traditional military procurement cycles.
The Software Layer May Become the Strategic Battleground
The partnership also highlights a developing competitive layer within the defense-technology market: mission software.
Hardware remains critical, but software increasingly determines how effectively different systems can share information, coordinate actions and incorporate new capabilities.
Companies such as Anduril, Palantir and Shield AI have helped push software-defined and AI-enabled defense systems further into mainstream defense procurement discussions, while established defense contractors are also investing heavily in autonomous systems and networked architectures.
The competitive question is therefore not simply which company produces the most capable autonomous vehicle.
It is increasingly about which platform can become the operating environment connecting multiple systems.
For Quantum Systems and XTEND, interoperability is consequently both a technical objective and a commercial strategy.
XTEND says its systems have been deployed in more than 30 countries, with more than 12,500 systems deployed and operational experience across five combat zones. Those figures are company-provided and should be viewed as such.
Implications for Defense Technology Investment
The partnership also fits into a broader investment thesis around European defense technology.
NATO’s higher spending targets are expected to create demand across weapons, communications, cybersecurity, autonomous systems, sensors, logistics and defense software. NATO has specifically identified industrial capacity and emerging technology as priorities within its new investment framework.
For investors and defense-technology buyers, this means software interoperability could become an increasingly important differentiator.
A platform that works only within one vendor’s ecosystem can create additional integration costs as fleets become more diverse. By contrast, open and modular architectures can potentially allow governments to combine capabilities from multiple suppliers.
The challenge is that interoperability in defense is more demanding than interoperability in commercial software.
Systems must function under degraded communications, contested environments and strict cybersecurity requirements. They also need clear authorization boundaries between autonomous behavior and human decision-making.
That makes the integration of XOS into MOSAIC UXS strategically significant, but it does not by itself demonstrate that the companies have solved those broader challenges.
The next test will be customer deployment.
The existing European NATO program gives the partnership an operational reference point. Further demonstrations and customer programs planned for 2026 and beyond will indicate whether the combined software architecture can move from a compelling interoperability proposition to a repeatable procurement model.
Why It Matters
The Quantum Systems- XTEND agreement reflects a broader change in defense technology: autonomous capabilities are increasingly being evaluated as components of connected mission systems rather than standalone machines.
As NATO increases defense investment and pushes allies toward faster technology adoption, the companies that can connect sensors, autonomous platforms, mission software and human operators may capture a larger share of the emerging defense-technology stack.
For the industry, the long-term opportunity is therefore not simply more autonomous drones.
It is the development of software-defined mission infrastructure capable of coordinating increasingly heterogeneous autonomous fleets.
Market Landscape
NATO’s 2025 investment commitment has created a long-term spending framework that favors modernization, emerging technology and defense-industrial capacity. European Allies and Canada increased combined defense expenditure by more than $90 billion in 2025, while NATO’s 2035 target calls for 5% of GDP annually across core defense and broader defense-security investment.
At the technology level, autonomous systems are becoming part of this modernization cycle. The emerging competitive landscape includes drone manufacturers, AI companies, defense primes, robotics vendors and mission-software providers.
The next market phase is likely to place greater emphasis on interoperability, open architectures, edge AI, autonomous coordination, human-machine teaming and rapid integration.
That favors vendors able to provide an ecosystem rather than a single platform.
