Military satellites could be refuelled in orbit

The UK Ministry of Defence is considering in-orbit servicing and refuelling technologies to extend the operating life of military satellites, according to a parliamentary answer reported on October 21, 2026. Possible life-extension work for existing Skynet 5 communications spacecraft could use servicing, assembly and manufacturing methods developed for on-orbit operations. Any requirement for future defence satellites to be refuellable would be assessed separately for each capability rather than mandated across the fleet. The ministry's comments describe options under consideration, not an awarded refuelling mission, a selected servicing vehicle or an announced modification contract for Skynet 5.
