Most digital twins model a platform. That is useful for maintenance and close to useless for operations, because a task group’s problems are rarely confined to one hull.

A twin of operations mirrors the whole group in near real time: ships, aircraft, the logistics tail, and the sea and weather they are all working in. The point is not visualisation. It is being able to ask what happens if, and get an answer before the decision has to be made.

What feeds it

ISR streams in standard form so they can be used without bespoke adapters, following NATO STANAG 4609 and 4559. Position, navigation and timing fused from GNSS, inertial units and, increasingly, quantum sensing trials, on the assumption that satellite timing will be denied at the worst possible moment. And the environment itself: ocean models and wave spectra, which decide what the group can physically do that day.

What it computes

Convoy routing run as agent-based simulation rather than a single plan. Maintenance predicted far enough ahead to be scheduled rather than suffered. Fuel burn optimised against the route actually available. And emission control posture planned deliberately, because the cheapest way to lose a task group is to let it announce itself.

Sharing it safely

A twin that cannot be shared across domains is a briefing tool. Dissemination therefore carries security labels on the data itself, in line with allied information security guidance, and the cryptography is built to be replaced as post-quantum standards land.

The gains are unglamorous and worth having: single-digit percentage improvements in logistics efficiency, routing that keeps the group quieter, and rehearsal of options in minutes rather than days.
