How the evidence works

The project combines different sources of evidence to estimate which vehicles remain in active service.

Radiolocation messages indicate that an aircraft or vessel is operating.

Registrations, callsigns and production information connect observations to a vehicle.

Original photographs add clear, human-verifiable evidence of active use.
