The UK’s next-generation military communications satellite, Skynet 6A, has achieved a major developmental milestone with the successful coupling of its communications and service modules. The integration was carried out at the National Satellite Test Facility (NSTF) in Harwell, Oxfordshire, operated by RAL Space under the Science and Technology Facilities Council.
Built in Britain by Airbus
Skynet 6A is being developed by Airbus at its advanced facilities in Stevenage and Portsmouth. It is designed to provide secure, high-capacity communications for the UK Armed Forces and allied partners. The recent coupling marks the first time a large geostationary-orbit (GEO) communications satellite has been integrated on British soil.
“This significant development in the programme will allow Airbus to complete final baseline testing at our Stevenage site, followed by environmental testing back at NSTF later this year,” said Ben Bridge, Chairman of Airbus Defence and Space UK.
Enhanced Capability for Armed Forces
Scheduled to enter service in 2027, Skynet 6A will offer three-and-a-half times more capacity than the current Skynet 5 satellites. The satellite features full military hardening and is equipped with advanced technologies to support secure global communications across diverse operational environments.
The Skynet programme has supported UK military communications for over five decades. Skynet 6A builds on this legacy with enhanced design features and mission adaptability to meet the evolving needs of defense operations.
National Collaboration and Technical Excellence
“Congratulations to Airbus Defence and Space, RAL Space and the MOD project team on achieving this impressive milestone,” said Barry Austin, Skynet Programme Manager at Defence Digital. “Once operational, Skynet 6A will be critical to our Armed Forces’ military satellite communications capability and ensure they continue to receive world-class connectivity globally.”
Earlier this year, the satellite’s antennas underwent successful testing at NSTF’s electromagnetic compatibility facility, validating their performance. The current integration milestone represents one of the most complex engineering steps in the satellite’s lifecycle.
UK Satellite Testing Capability Strengthened
The NSTF milestone also represents a landmark for the UK’s growing space sector. “Welcoming our first customers represents a significant achievement for the NSTF, and we are proud to support Airbus with the integration and testing of Skynet 6A,” said Sean Stewart, Head of Environmental Test at RAL Space. “This milestone is a testament to the dedication of all involved and marks an exciting step for the UK as we prepare to host many more satellites of this scale.”
A Strategic Leap in Military Communications
Skynet 6A is set to reinforce the UK Ministry of Defence’s strategic communications infrastructure. Its development underscores the nation’s long-term commitment to secure, resilient, and sovereign space-based capabilities, reinforcing the UK’s leadership in defense innovation and aerospace technology.
