Common Questions
Why is Airbus buying Ultra Cyber from Cobham?
Airbus is acquiring Ultra Cyber to strengthen its defence-cyber portfolio with UK sovereign cryptography capability and MoD-cleared programme expertise.

What regulatory approvals does the Airbus Ultra Cyber deal need in the UK?
The deal requires both a Prudential Regulation Authority financial review and a UK Ministry of Defence security-clearance review of the change of control. The MoD review is the more complex element — UK sovereign cryptography capability moving to a non-UK ultimate owner has no direct precedent in recent NSIA decisions.Source: Briefing analysis
Does the National Security and Investment Act apply to the Airbus Ultra Cyber deal?
Ultra Cyber's cryptography work for MoD programmes falls within the NSIA's advanced materials and military-adjacent categories that require mandatory notification. Ministers have the power to impose conditions, including sovereignty-of-control requirements, though no public indication of their intent has been given.

Background

Ultra Cyber is a UK-based sovereign cybersecurity company specialising in cryptography and data-security systems for UK Ministry of Defence programmes. It originated within the wider Ultra Electronics group before Cobham acquired it as part of a broader portfolio deal. Its cryptography work sits within the UK's defence-industrial supply chain at a clearance level requiring MoD vetting for personnel and facilities, making it one of the most sensitive UK cyber-industrial assets by classification tier.

Airbus signed a definitive agreement in April 2026 to acquire Ultra Cyber from Cobham, moving UK MoD-cleared cryptography capability inside a European continental defence prime for the first time. The acquisition will trigger both a Prudential Regulation Authority financial review and a UK Ministry of Defence security-clearance review of the change of control — the latter being structurally novel, given no direct precedent for MoD-cleared cryptography passing to a non-UK ultimate owner under the NSIA regime.

The Airbus acquisition of Ultra Cyber from Cobham raises the core sovereignty question of whether MoD-cleared cryptography should carry a control condition when changing hands to a foreign industrial prime. The National Security and Investment Act gives ministers the mechanism to impose conditions; the Ultra Cyber deal tests whether that mechanism will be actively used for cyber-specific capability rather than only for physical hardware.

The transaction completes a week in which two UK cyber-industrial assets — Ultra Cyber and Beazley's incident-response intelligence — moved outside UK consolidated ownership, while NCSC simultaneously launched SilentGlass as the one UK-retaining deal of the three. For prime contractors across the UK defence-industrial base, the MoD's response to the Airbus review will set precedent.
