Airbus is competing with Lockheed Martin for a military communications programme that will shape Britain’s satellite manufacturing base, domestic design authority, and space engineering workforce well into the 2040s.
The Ministry of Defence’s Skynet 6 Wideband Satellite System competition covers future geostationary spacecraft, communications payloads, ground infrastructure, launch activity, and the systems required to operate secure military networks. Defence Digital has described the programme as the largest national space procurement undertaken by the UK.
Although the competition was initially presented with a value above £1.5 billion, its anticipated scope has subsequently been valued at approximately £2.4 billion. Airbus Defence and Space UK and Lockheed Martin UK remain the principal competitors for the work.
Unite has called for the contract to be awarded to Airbus, arguing that the company’s established operations at Stevenage and Portsmouth provide the stronger route for retaining satellite design, payload integration, manufacturing experience, and skilled employment in Britain. The union estimates that hundreds of existing positions could be affected by the decision.
At Stevenage, Airbus undertakes spacecraft engineering, structural manufacture, assembly, integration, and testing, while its Portsmouth operation develops and integrates communications payloads and digital processors. The company’s current Skynet 6A spacecraft was designed and assembled in the UK, using facilities and technical teams that support its proposal for the wider system.
Skynet 6A is being procured separately from the Wideband Satellite System, although the programme demonstrates the industrial capability on which Airbus is building its bid. The spacecraft is intended to supplement the Skynet 5 constellation with greater capacity, hardened communications, and secure connectivity for British forces.
Lockheed Martin has proposed a different domestic manufacturing model centred partly on new capability in north-east England. Its offer includes direct employment, a wider British supply base, and the potential establishment of additional space manufacturing activity, with around 500 direct positions and up to 1,500 supporting roles projected by the company.
The Ministry of Defence is assessing the proposals through a technological capital framework that gives weight to sovereign access, UK design authority, domestic assembly, integration, testing, and workforce development. Final assembly represents only one element of that capability, since long-term control also depends on technical data, intellectual property, qualified processes, and the ability to modify the system independently.
Sovereignty extends through the satellite lifecycle
Military communications satellites combine secure processors, antennas, payload electronics, propulsion, power systems, thermal control, structures, software, encryption, and ground equipment within a platform expected to operate for many years without physical maintenance. Each element must withstand launch vibration, radiation, vacuum, thermal cycling, and the demands of continuous orbital service.
Qualification cycles are consequently lengthy, while specialist employees accumulate experience that cannot be recreated quickly when programmes are transferred or production gaps emerge. Engineers who understand payload integration, contamination control, thermal vacuum testing, electromagnetic compatibility, and secure communications provide continuity across successive generations of spacecraft.
The contract will also determine where design changes and upgrades can be undertaken once the satellites are in service. Military communications requirements evolve as data volumes rise, operational concepts change, and adversaries develop stronger electronic warfare, cyber, and counter-space capabilities.
Retaining design authority within Britain would allow some modifications to be managed through domestic facilities, although local production can still depend on imported semiconductors, specialist materials, propulsion components, and other internationally sourced equipment. Sovereignty therefore depends on the detail of the supply chain rather than the nationality of the prime contractor alone.
A new entrant could establish substantial British capability if technology transfer, workshare, intellectual property, supplier commitments, and long-term support obligations are defined clearly within the contract. Conversely, headline employment figures may have limited value when the most technically important design and manufacturing decisions remain elsewhere.
Cost and schedule will sit alongside industrial considerations. A proposal drawing on systems produced at greater international scale may offer access to mature technology or a broader supplier base, while an established domestic operation can reduce the disruption, qualification burden, and learning associated with creating a new manufacturing network.
Secure satellite communications are becoming more demanding as armed forces rely on distributed command systems, uncrewed platforms, remote sensors, and data-intensive operations beyond terrestrial networks. Future spacecraft must provide capacity while remaining resilient against interference, cyber attack, and physical threats to orbital assets.
Ground systems will be as important as the spacecraft. Network management, terminal compatibility, cryptographic systems, launch preparation, orbit raising, cyber protection, and through-life upgrades all require sustained engineering support once the manufacturing phase has ended.
The successful proposal will therefore establish an industrial structure extending across design, production, operations, maintenance, and future modification. Britain’s decision will determine where a substantial share of that work is performed and whether existing satellite engineering capability is sustained, expanded, or replaced by a new operating model.
