Within 2017 Shift
One of the most important developments in the modern UFO disclosure era was not the release of a video, a congressional hearing or a Pentagon report. It was a change in language.

Introduction
The change occurred alongside the wave of attention triggered by the 2017 revelations about Pentagon investigations into unusual military encounters. Officials increasingly argued that the term UFO carried decades of cultural baggage that discouraged reporting and encouraged assumptions about extraterrestrial explanations. UAP, by contrast, was presented as a neutral investigative category focused on aviation safety, intelligence collection and national security rather than on claims about aliens. The result was a significant change in reporting behaviour, media coverage and government policy.

The Cultural Baggage Attached to “UFO”
The original meaning of UFO was straightforward. The term was introduced by the US Air Force in the 1950s because “flying saucer” was considered too narrow and sensational. A UFO simply meant an object observed in the sky that had not yet been identified. [Wikipedia]WikipediaUnidentified flying objectUnidentified flying object
Over time, however, the public meaning diverged from the official definition. By the end of the twentieth century, “UFO” had become strongly associated with extraterrestrial spacecraft in popular culture. Television programmes, films, conspiracy theories, contactee movements and tabloid journalism all reinforced the idea that UFOs were fundamentally about aliens. As a result, the word carried assumptions that often went far beyond its literal meaning.

This created a practical problem for governments and military organisations. Pilots who reported unusual observations risked being perceived as claiming they had seen alien craft. Researchers studying unexplained observations faced accusations that they were promoting fringe beliefs. The terminology itself had become an obstacle to routine reporting and investigation.
The issue was recognised even before the modern disclosure era. The phrase “unidentified aerial phenomenon” appeared in specialist discussions as early as the late 1960s and was occasionally proposed as a less loaded alternative. However, it remained relatively obscure for decades. [Wikipedia]WikipediaPentagon UFO videosThe Pentagon later addressed and officially released the first three videos of unidentified aerial phenomena (UAP)…
The significance of the post-2017 period is that major institutions finally embraced the alternative terminology and made it part of official practice.
Why Defence and Intelligence Officials Wanted a New Term
The move toward UAP was driven less by scientific theory than by bureaucratic necessity.
After a series of military encounters became public, particularly incidents involving Navy aviators, defence officials increasingly framed the issue as one of airspace awareness and operational safety. The central question was not whether extraterrestrials existed. The concern was that military personnel were encountering objects or sensor tracks that they could not immediately explain.
Using the term UAP allowed officials to separate the reporting process from assumptions about the cause.
The Office of the Director of National Intelligence’s 2021 Preliminary Assessment repeatedly used “unidentified aerial phenomena” and emphasised the difficulty of drawing conclusions because of limited and inconsistent reporting. The report specifically noted that stigma associated with previous reporting practices had affected data collection and hindered understanding of the phenomenon. [National Intelligence Office]dni.govPrelimary Assessment UAP 20210625National Intelligence OfficePreliminary Assessment: Unidentified Aerial Phenomena…Jun 25, 2021 — The limited amount of high-quality re…
This point is often overlooked. The government did not merely rename UFOs. Officials argued that the old language had contributed to a reporting problem. If witnesses avoided filing reports because they feared ridicule, analysts received fewer cases and lower-quality data. Changing terminology was therefore intended to improve the flow of information.
In effect, UAP functioned as a data-collection tool as much as a descriptive term.
How UAP Changed Reporting Incentives
The most immediate consequence of the new terminology was a shift in reporting incentives.
Under the UFO framework, a pilot reporting an encounter risked being associated with decades of cultural stereotypes. Under the UAP framework, the same report could be presented as a routine aviation or intelligence matter.
Several incentives changed simultaneously:
- Witnesses could report unusual observations without appearing to endorse extraordinary explanations.
- Commanders could treat reports as operational information rather than public-relations liabilities.
- Intelligence analysts could focus on identifying potential threats rather than debating cultural narratives.
- Journalists could cover incidents as defence and oversight stories rather than exclusively as paranormal stories.
The effect became visible in official procedures. Military organisations increasingly developed standardised reporting channels for UAP incidents. The emphasis shifted toward collecting radar data, infrared imagery, flight records and sensor information rather than relying solely on eyewitness testimony. [National Intelligence Office]dni.govPrelimary Assessment UAP 20210625National Intelligence OfficePreliminary Assessment: Unidentified Aerial Phenomena…Jun 25, 2021 — The limited amount of high-quality re…
This procedural shift reflected a broader institutional goal: normalise reporting first, determine explanations later.
The terminology helped create that separation.
Why “Phenomena” Was More Useful Than “Objects”
One subtle but important feature of the new terminology was the replacement of the word “object”.
“Unidentified flying object” implicitly suggests that an observer has detected a discrete object. Yet investigators often encounter cases where that assumption may be premature.
A radar track might represent an actual aircraft, a balloon, atmospheric effects, electronic interference, software error or a combination of factors. Infrared imagery may capture signatures that are difficult to interpret. Visual observations can involve misidentifications of conventional objects.
The word “phenomenon” deliberately widened the category.
Instead of assuming the existence of an unknown craft, investigators could simply acknowledge an unexplained observation. This made the terminology more compatible with intelligence analysis and scientific investigation. The category described a state of knowledge rather than a conclusion about what had been observed. [ResearchGate]researchgate.netAnalysis of ODNI Preliminary Assessment: Unidentified…Those definitions are reproduced here for convenience: Unidentified…
In practical terms, UAP meant: something was observed, but its nature remained unresolved.
That formulation was far more useful for government investigators than terminology that carried implicit assumptions.
The Influence of the 2017 Pentagon Revelations
The 2017 reporting on Pentagon programmes and Navy encounters accelerated the adoption of UAP terminology.
Before those revelations, discussion of unexplained sightings was largely confined to specialist communities, enthusiasts and occasional official inquiries. After the revelations, the subject entered mainstream political and media discourse.
What made the new language especially effective was that it aligned with the way the story was being reframed. The emerging narrative centred on:
- Military pilots.
- Restricted airspace.
- Sensor systems.
- Intelligence failures.
- Aviation safety concerns. [govinfo.gov]govinfo.govSource details in endnotes.
- Congressional oversight.
These topics fit naturally with “unidentified aerial phenomena”. [govinfo.gov]govinfo.govSource details in endnotes.
They fit far less naturally with “UFOs”, a term that many audiences immediately associated with extraterrestrial visitation.
As the story moved into congressional hearings, intelligence assessments and defence briefings, the new terminology became increasingly dominant. [National Intelligence Office]dni.govPrelimary Assessment UAP 20210625National Intelligence OfficePreliminary Assessment: Unidentified Aerial Phenomena…Jun 25, 2021 — The limited amount of high-quality re…
The linguistic shift therefore reinforced the broader strategic reframing that characterised the post-2017 disclosure movement.
How the Media Followed the Government’s Language
Language used by governments often shapes language used by journalists.
As Pentagon officials, intelligence agencies and congressional committees increasingly adopted UAP, major news organisations gradually followed. Stories that might once have been headlined with “UFO” increasingly used “UAP” when discussing official investigations.
This mattered because terminology influences interpretation.
A headline about a “UFO sighting” tends to invoke popular cultural associations. A headline about a “UAP incident” sounds more technical, bureaucratic and investigative.
The underlying event may be identical, but the framing changes the reader’s expectations.
This shift helped move coverage from entertainment and fringe-interest sections into defence, science and national-security reporting. It also encouraged journalists to focus more heavily on evidence such as sensor data, pilot testimony and government records rather than on speculation about extraterrestrial origins.

From “Aerial” to “Anomalous”
The evolution of terminology did not stop with UAP.
In 2022 and 2023, US law and government agencies increasingly redefined UAP as “unidentified anomalous phenomena” rather than “unidentified aerial phenomena”.
The reason was scope.
Investigators wanted terminology that could encompass observations occurring not only in the air but also in space, underwater and in so-called transmedium environments. The 2023 National Defense Authorization Act expanded the formal definition accordingly, and agencies such as NASA and the Pentagon’s All-domain Anomaly Resolution Office adopted the broader usage.

NASA’s public materials now define UAP in this broader sense and emphasise that the term refers to observations that cannot presently be identified, not to any particular explanation. [NASA Science]science.nasa.govNASA ScienceUAP9 Jun 2022 — A study team to examine unidentified anomalous phenomena (UAPs) – that is, observations of events in the sky…
This second terminological shift followed the same logic as the first: broaden the category, minimise assumptions and focus attention on investigation rather than interpretation.
Why the Terminology Change Was So Consequential
The replacement of UFO with UAP was not merely a public-relations exercise. It altered the institutional environment in which unexplained sightings were discussed.
The new language reduced stigma, encouraged reporting, supported standardised data collection and aligned the issue with aviation safety and national-security concerns. It also narrowed the strongest claim implied by the discussion. Officials no longer needed to debate whether a report involved an alien spacecraft before deciding whether it deserved investigation.
Instead, they could focus on a simpler question: was there an observation that remained unexplained?
That change in framing became one of the defining mechanisms of the post-2017 disclosure era. The modern disclosure movement gained political traction not because governments suddenly endorsed extraordinary explanations, but because they adopted terminology that allowed unresolved observations to be discussed without requiring any extraordinary explanation at all. By replacing a culturally charged label with a more neutral investigative category, officials transformed both the conversation and the institutions responsible for managing it.
