 APPENDIX B: GLOSSARY OF TERMS

Unidentified Anomalous Phenomenon (UAP): Sources of anomalous detections in one or more domain (i.e., airborne, seaborne, spaceborne, and/or transmedium) that are not yet attributable to known actors and that demonstrate behaviors that are not readily understood by sensors or observers. "Anomalous detections" include but are not limited to phenomena that demonstrate apparent capabilities or material that exceed known performance envelopes. A UAP may consist of one or more unidentified anomalous objects and may persist over an extended period of time.

Spaceborne UAP: Sources of anomalous detections above the Karman Line (i.e., 100 km above Earth's mean sea level).

Airborne UAP: Sources of anomalous detections between Earth's mean sea level and the Karman Line.

Seaborne UAP: Sources of anomalous detections at or below Earth's mean sea level within a body of water.

Transmedium UAP: Sources of anomalous detections that transit more than one domain.

UAP Objects and Material: Corporeal artifacts of UAP. UAP may contain one or more UAP objects (e.g., airborne craft exhibiting apparent anomalous capabilities). UAP material are samples, in whole or in part, of UAP objects (e.g., debris).

UAP Data: Any records of UAP detection, observation, identification, effects (on persons or equipment), mitigation, and material-exploitation. UAP data includes but is not limited to written notes, still and full-motion photographs, audio recordings, full-/ partial-spectrum characterization, and digital record from observers, sensors, platforms, debriefers, and investigators.

UAP Incident: Any occurrence where UAP is detected by persons or sensors.

UAP Incursion: Any UAP incident in, on, or near U.S. military installations, operating areas, training areas, special use airspace, proximity operations, and/or other national security areas of interest. Other areas of interest include but are not limited to U.S. critical infrastructure, IC installations and platforms, and national defense equities of Allied military and intelligence coalitions (e.g., Five Eyes).

UAP Engagement: Bringing UAP under kinetic or non-kinetic fire, to deny, disrupt, or destroy the phenomenon and/or its object(s).

UAP Interrogation: The elicitation of UAP location, capabilities, characteristics, and/or intent using passive and/or active sensing capabilities—including but not limited to electro-optical/imagery, infrared/thermal, radiofrequency/radar, light/laser/lidar/ladar, electromagnetic, gravitational, and radioactive means.
