How the evidence works

Observed.
Identified.
Documented.

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

01

Detect activity

Radiolocation messages indicate that an aircraft or vessel is operating.

02

Verify identity

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

03

Document visually

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