Laying the digital foundations for the Global Combat Air Program
Delivering GCAP demands collaboration across boundaries that don’t naturally align between nations, organisations, classification levels and sovereign frameworks.
As the programme grows, so does the complexity. More partners. More sensitive data. More points where things can break.
Adversaries are already targeting the supply chains, software pipelines and industrial ecosystems this programme depends on. Every day collaboration runs on models built for a simpler world and the gap between ambition and resilience widens.
The challenge is not collaboration itself. It is maintaining trust when everything around it is under pressure.
Secure Design Collaboration Framework
Precision trust for sovereign collaboration.
Secure collaboration is at the heart of modern defence programmes. But sharing sensitive data across partners, systems and borders without putting intellectual property at risk remains a real challenge.
This whitepaper explores Fujitsu’s Secure Design Collaboration Framework that enables continuously governed collaboration across complex defence ecosystems using Zero Trust architecture, Attribute-Based Access Control and data-centric security principles.
Built for nations, industrial partners and classified environments, the framework supports secure collaboration at pace while maintaining sovereignty, control and compliance.

Future combat air depends on more than advanced platforms. It depends on whether nations, industrial partners and digital ecosystems can collaborate securely under continuous operational, cyber and geopolitical pressure.
Behind every successful GCAP collaboration sits a chain of decisions most multinational defence partnerships struggle to maintain consistently at scale. Who can access this data? Under what conditions? At what classification? For which nation? For how long? And how does collaboration adapt as threats, policies and operational requirements evolve?
Every unresolved layer creates exposure:
Sensitive design data moving across tri-national environments
Supply-chain ecosystems extending across hundreds of organisations
Multiple classification domains requiring continuous assurance
Export control requirements differing across national frameworks
Persistent adversary targeting of industrial and collaborative environments
Through-life support models expected to hold for decades
What begins as a technical vulnerability rarely remains technical for long. It surfaces in assurance reviews, operational delay, partner trust breakdowns and national scrutiny.
Fujitsu helps GCAP partners establish the controls, governance and digital foundations required for collaboration that holds at sovereign scale.
Strategic Threat Assessment and Implications for Global Combat Air
The threats shaping this programme are evolving faster than most partners have fully mapped.
Commissioned and developed by Fujitsu, this independent 55-page assessment explores the strategic landscape facing future combat air through to 2040. It covers everything from targeted pressure on allied industrial ecosystems and supply chains, to the growing influence of AI, quantum and space technologies.
Drawing on open-source intelligence across state, cyber and emerging technology domains, the report translates these risks into clear implications for GCAP. This includes digital resilience, sovereign architecture and the realities of operating within a tri-national framework.
Understanding the threat is not the end of the conversation. It is where better programme decisions begin.
GCAP’s credibility will depend not only on its performance in controlled conditions but on its ability to withstand sustained strategic pressure, rapid technological change and persistent adversary interference.
Cyber operations remain among the most persistent, adaptive and strategically significant threats facing the United Kingdom, its allies and their industrial bases.
The tri-national nature of GCAP significantly expands its attack surface across three legal systems, three industrial ecosystems and three national assurance regimes.
Our solutions
Delivering GCAP requires more than advanced technology. It demands secure workplaces that enable trusted collaboration, cloud platforms that provide resilience and adaptability, and data services that transform information into actionable insight.
Discover how Fujitsu brings these capabilities together to help support secure, sovereign and effective programme delivery across the GCAP ecosystem.
Workplace services
Secure workplace services enable trusted collaboration across nations, partners and security domains, helping GCAP teams work effectively while maintaining assurance and control.
Data platform services
Programmes such as GCAP rely on secure collaboration across nations and partners. Trusted data therefore becomes the foundation for operational effectiveness, assurance and future innovation.
Secure cloud
Secure cloud capabilities help GCAP partners share information, develop services and operate effectively across high-assurance environments, without compromising security, control or sovereignty requirements.
Collaboration That Withstands Pressure
GCAP relies on secure collaboration across nations, supply chains and classification domains. Delivering that requires more than technology. It demands experience, trusted capability and the ability to operate under constant operational, cyber and geopolitical pressure.
Fujitsu brings these together to support collaboration that remains reliable, even under sustained operational and strategic pressure.

Innovation built for the decades ahead
The right partner does more than protect the programme. They help ensure collaboration remains trusted, even under sustained operational and strategic pressure.
The Fujitsu 5S Model
Future combat air depends on more than advanced aircraft alone. GCAP requires the conditions that allow nations, industrial partners and defence ecosystems to collaborate securely, adapt continuously and sustain operational advantage under persistent strategic pressure.
Fujitsu’s 5S model brings those conditions together: Security, Sovereignty, Scalability, Speed and Sustainability. Together, they provide the framework through which Fujitsu enables trusted collaboration across complex sovereign defence environments.
These five pillars define the essential conditions required to enable secure, scalable and resilient collaboration across the GCAP ecosystem:
- Security: Continuous trust across every interaction.
- Sovereignty: National control without hindering collaboration.
- Scalability: Enabling programme growth without limits.
- Speed: Accelerating at the pace that the mission demands.
- Sustainability: Designed to evolve across decades of change.
Understanding sovereignty in complex defense ecosystems
Technology sovereignty is often discussed as a requirement, but rarely defined with precision.
This whitepaper explores how defence organisations can move beyond rhetoric and take a risk-based approach to sovereignty, helping programmes such as GCAP maintain control, resilience and operational effectiveness in an increasingly contested environment.
Where pressure is already visible
The challenges facing GCAP are not emerging. They are already shaping how defence organisations operate today.
From supply chains under strain to decisions made in contested environments, the ability to respond with clarity and control is becoming critical.
These DSEI insights show how organisations are addressing those pressures and where advantage is starting to shift.
Securing Supply Chains Maintaining control across complex networks
As collaboration expands across nations and suppliers, supply chains have become a point of exposure as well as strength.
This paper explores how organisations can move from reactive risk management to a more deliberate, data-led approach to resilience across complex networks.
What you will take away:
- Why supply chains now sit at the centre of national security
- How visibility improves control across suppliers and systems
- What it takes to manage risk in interdependent environments
Supply chain resilience is not a fixed state. It is a continuous capability, shaped by visibility, collaboration and informed decision-making.
Decision Transformation: Reframing Digital Warfare for Strategic Impact
Improving how decisions are made, not just how systems operate
In modern defence, advantage depends on making better decisions, faster and with greater clarity.
This paper explores how organisations can strengthen decision-making by combining human judgement with AI insight, supported by clearer frameworks and measurable outcomes.
What you will take away:
- Why decision-making is becoming the decisive edge
- How prediction shapes operational advantage
- The role of trust and explainability in AI-enabled systems
Digital transformation in defence is, at its core, a transformation of decision-making.
From pressure to advantage
These challenges do not sit in isolation. They converge in programmes like GCAP, where collaboration, decision-making and resilience must work together.
Understanding the pressure is the first step. Acting on it is what creates advantage.
