Royal Navy and US Navy data-link interoperability

British and American ships can exchange data, but the public record does not show a fully common combat network, and a planned Type 45 integration upgrade was cut.

Question

How closely are Royal Navy and US Navy combat systems integrated when their ships operate together?

Short answer

They likely use bridging and data sharing rather than a single fully common network, but the exact arrangement is not public.

Notes

The Royal Navy did not receive a planned interlink upgrade for the Type 45 destroyers and had not spread it through the wider fleet. Some form of bridging or direct data exchange is therefore the more plausible public explanation for allied interoperability. The precise arrangement is not openly available. Any account of the architecture must stop short of claiming details that the public record does not establish.
