Range Fouler is a standardized U.S. Navy reporting form for unauthorized airspace intrusions into controlled military zones during operations or training. The designation recurs across multiple PURSUE releases. src-loeb-pursue-release-04-2026-07 documents three numbered cases from Release 04:
- PR106 (2020, Eastern U.S.) — small, constant-direction, metallic/reflective object.
- PR112 (2019, Eastern U.S.) — five military-affiliated witnesses; flight characteristics unlike anything one observer had seen in 28 years.
- PR116 (Atlantic) — maroon, 12-15 ft, balloon-like object that drifted with the wind (the viral “floating brain” case; see src-floating-brain-ai-viral-2026-07).
