Range Fouler
Military shorthand for anything that intrudes into airspace or sea space set aside for training or operations: a stray boat, a civilian aircraft, a drone, a balloon, or an object aircrew cannot identify. The term is deliberately neutral. It describes an airspace-management problem, not a claim about what the intruder is.
The US Navy logs these on a standardised printed form, the Range Fouler Debrief Form, several filled copies of which appear in PURSUE Release 01. The form carries identifying details, observation basics, geometry and sensor fields, a physical-description checklist and a free-text block. Reports are stripped of identifying information before analysis through a programme the documents call SPEAR.
The existence of a routine, structured intake form is itself the finding. It shows the military treats unidentified airspace intrusions as a recurring, expected operational problem with its own paperwork, not as a novelty.
