Computacenter has won a £150m device support contract with the Ministry of Defence (MoD), covering over 220,000 laptops and desktops worldwide.
This four-year deal, part of the MoD's strategy for smaller, more efficient contracts, is expected to cut costs by around 64% (£84m).
The contract also prompts job creation at Computacenter's Hatfield and Nottingham sites.
Minister for Defence Procurement, James Cartlidge, said: “Delivering on our digital transformation will ensure high-quality, rapidly accessible global data, which is a critical component of our fighting power. Bolstered technology can strengthen our deterrence, our resilience, and our national prosperity.
“The service will improve performance standards and speed of access across 220,000 devices including laptops, desktops, peripherals and software applications.”
