As GCAP grows, multinational defence programmes need to move faster

Canada’s observer role highlights why trusted information sharing is a strategic capability in multinational defence programmes.

On 21 July 2026, Canada became the first observer nation in the Global Combat Air Programme (GCAP), the joint programme between the UK, Italy and Japan to develop a next-generation combat aircraft. The announcement marked another step in the growth of a complex, multinational defence partnership.

Kahootz understands the collaboration challenge behind programmes like this. Through Defence Share, our secure collaboration platform supports UK Ministry of Defence international programmes like GCAP, enabling information up to OFFICIAL-SENSITIVE to be shared with defence industry partners, other government departments and allied nations. That experience has shown us that secure information sharing is not a supporting detail. It is part of the infrastructure that allows complex programmes to work.

Collaboration without compromising sovereignty
Canada’s observer status also shows that international collaboration can develop in stages. According to the four nations’ joint statement, it gives Canada the opportunity to better understand GCAP’s governance, capabilities, industrial framework and security. Canada retains its own national responsibilities and decision-making authority. That is a useful model for complex programmes: effective collaboration depends on being clear about what participants share, what they control and how information moves between them.

That becomes difficult when governments, prime contractors, suppliers and specialist partners all need to contribute. They may have different security classifications, commercial interests and rules for handling sensitive information. Progress depends on sharing enough to work together while retaining control over data, intellectual property and decisions that remain each participant’s responsibility.

The collaboration challenge is operational
In a programme of this scale, information moves between organisations throughout its lifecycle. New partners may join. Existing roles change. Decisions need to be recorded; documents need to remain current and access must reflect each participant’s responsibilities.

When that work is managed through disconnected systems and email, people can lose confidence in which document is authoritative or who owns a decision. Information may be shared too widely, or not quickly enough with the people who need it. Those problems affect delivery, accountability and trust.

Secure collaboration is therefore more than file sharing. It should give authorised participants a reliable place to find current information, understand decisions and contribute to the work. It should also give programme and security teams confidence that information is being shared according to agreed rules.

The balance matters. Controls that are difficult to use can encourage workarounds, while access that is too broad can undermine confidence. The most useful collaboration environments make secure working straightforward without weakening governance.

New partners need context, not just access
Canada’s observer status highlights another often overlooked part of collaboration: bringing a new stakeholder into an established programme.

Granting access to a folder is not enough. A new participant needs to understand the programme’s context, the decisions already made, the information that is authoritative and the responsibilities attached to their role. That context is easier to preserve when information, discussions and decisions are managed in a structured environment.

This matters whenever a defence programme changes shape. It may involve a new national partner, a supplier joining the industrial base or a specialist organisation contributing to a defined part of the work. The collaboration environment should support that relationship without weakening sovereignty or governance.

A lesson for the next phase of defence collaboration
GCAP demonstrates how defence capability is increasingly developed through networks rather than by one organisation working alone. That makes trusted collaboration a strategic capability.

The organisations best placed to contribute will be those that can share information with the right partners, protect sensitive material and maintain a clear record of how work is progressing. They will need to combine openness with control, and efficiency with accountability.

As more countries and organisations take part in major defence programmes, the quality of the collaboration environment will matter as much as the quality of the technology being developed. Sovereignty is not an obstacle to cooperation. It is one of the conditions that cooperation must respect.

Kahootz continues to support secure collaboration across defence and other sensitive working environments. Our UK team develops and supports the platform, backed by the long-term stability and shared expertise of the wider Vesta Software Group, Jonas Software and Constellation Software family.

Successful international collaboration is not about removing boundaries. It is about creating trusted ways for organisations to work across them.
