Multiple contracts for next-generation digital payload and other subsystems in the UK and in Montréal for the GEO satellite series supporting operations of the Japanese government.

TORONTO, June 25, 2026 /PRNewswire/ - MDA Space Ltd. (TSX: MDA) (NYSE: MDA), a trusted mission partner to the rapidly expanding global space industry, has been selected by Mitsubishi Electric Corporation (TOKYO: 6503) to design and manufacture the digital payload, antennas and various subsystems for the next-generation defence communications satellite program ordered by the Japan Ministry of Defense. This satellite program will replace DSN-2, also known as Kirameki-2, in geostationary orbit.

MDA Space in the UK will support the core technology for the advanced, anti-jamming, resilient multi-beam payload with digital beamforming that can be dynamically reconfigured in orbit. The MDA Space facility in Montréal will manufacture and test the advanced antenna solutions, including the analog repeater before shipping to Japan, where the assembly, integration and testing will be performed by Mitsubishi Electric.

The satellite will also be supported by MDA Space's legacy products for the deployable mechanism of thrusters and reflectors.

The announcement comes as the UK, Canada and Japan endeavour to strengthen their trade relationships.

The contract will be added to MDA Space's backlog in the second quarter of fiscal 2026.

"It's an honour for us to once again be collaborating with long-time customer Mitsubishi Electric, this time to provide key technology for Japan's critical defence communication infrastructure," said Mike Greenley, CEO of MDA Space. "Our advanced dual-use technologies combined with the expertise and reach of our global satellite team ideally position MDA Space to respond to robust demand for sovereign missions with secure and flexible capabilities."
