The Serial Number of the Navy
The Bureau Number is the unique identification number of a US Navy aircraft: assigned once, it accompanies the machine from delivery to decommissioning. BUNO appears in maintenance records, flight logs and accident reports.
Why Every Aircraft Has Its Number
Aircraft of the same type look identical – but every machine has its own history: maintenance, modifications, flight hours. The Bureau Number distinguishes them: technicians search by BUNO, spare parts are ordered by BUNO, the configuration of each individual aircraft is documented under its BUNO.
BUNO appears in this meaning constantly in documentation of US naval aviation. Note that the same number is often written BuNo or BUNO – both spellings stand for the Bureau Number of the aircraft.
