Skynet 5 satellite programme

UK (operation); France (launch) · 2007 (first launch) - 2022 (PFI programme ended)

The judgement call

Account-gated at launch

Skynet 5 was delivered under a Private Finance Initiative (PFI) model, a significant approach for defence procurement. - The programme provided assured satellite communications for the UK military and allies for over a decade. - The success of Skynet 5 led to the development of its successor, Skynet 6.

Key engineering challenges

Designing and building highly secure and resilient military communication satellites. - Ensuring global coverage and continuous service for deployed forces. - Managing the complex ground infrastructure for telemetry, tracking, and command.
