Undisclosed location (classified-network batch, PURSUE Release 02).Undisclosed location · four objects in an edited, cut-up video

An 8-minute-16-second clip circulates under the title “UAP USO Formation [CALLSIGN] (Mission),” where USO stands for unidentified submerged object, although neither the title nor the official description mentions water. According to the Pentagon office for these phenomena (AARO), four areas of contrast cross the frame together at the start, but the video was digitally altered before being uploaded to a classified network, has several cuts, and its last five seconds probably repeat an earlier stretch. The title was given by whoever uploaded it, in June 2024, and the video is part of a batch of 50 found on that network.

Why: The OVNI 66 blog proposes a group of four birds: "one clearly perceives the wingbeat of a group of 4 birds", even more visible than in PR050. It is a single amateur analysis; no official source supports it. (OVNI 66 (Pascal G.), "DOW-UAP-PR052, vol en formation de 4 PAN", Jun 2026 ↗)

Record of the event

DOW-UAP-PR052 — uploader title 'UAP USO Formation'; 8 minutes with a non-linear cut in the final segment

8-minute-16-second video posted on DVIDS on May 22, 2026 as DOW-UAP-PR052, location undisclosed. AARO describes it as likely derived from an infrared sensor aboard a U.S. military platform and digitally altered before being uploaded to a classified network.

What happened

This 8-minute-16-second video, cataloged as DOW-UAP-PR052, is one of 50 videos AARO located on a classified network while responding to the request eight members of the House of Representatives filed on March 6, 2026 for access to 51 potentially UAP-related records. According to AARO, many of those materials lack a substantiated chain of custody. DVIDS dates this file June 1, 2024, classifies it as B-roll video, and gives its location as "undisclosed location."

Per AARO, the title "UAP USO Formation [CALLSIGN] (Mission)" was chosen by whoever uploaded the file to the classified network in June 2024; it is not a Department of War designation. The acronym "USO" (Unidentified Submerged Object) suggests a maritime setting, but neither the full title nor AARO's visual description mentions water, an ocean surface, or any element confirming a submerged or coastal environment. AARO only assesses as "likely," without confirming, that the footage derives from an infrared sensor aboard a U.S. military platform, and it does not say which regional command is involved.

AARO describes the video with timestamps. It states that its description is provided for informational purposes only and should not be read as an analytical judgment, an investigative conclusion, or a determination about the event's validity, nature, or significance, and that the material was digitally altered before being uploaded to the classified network and is presented as received. Between seconds 0 and 5, four areas of contrast cross the frame from the lower-left third to the lower-right third of the screen (the "formation" the title announces). Between seconds 6 and 38, the video "appears to cut," reframing on the same four areas while elements of the sensor display enter and exit the frame. Between 0:39 and 6:08, over five and a half minutes, the video "seems to cut multiple times, applying various contrast filters and zoom levels."

Between 6:09 and 6:50 the sensor zooms in on the four areas, and between 6:51 and 8:10 they "become increasingly indistinct" as the video quality degrades. In the final seconds, 8:11 to 8:15, the video "appears to cut, or zoom out, likely cutting to an earlier portion of the video, with the areas of contrast more visible": according to that description, the ending is probably not the chronological end of the recording.

The material was uploaded to DVIDS on May 22, 2026, within PURSUE's second drop, with no coordinates, platform, or crew statement.

Why it matters

The record supports little. Four areas of contrast cross the frame together in the first five seconds, but the video was digitally altered before being uploaded to the classified network, and AARO's description shows it cut again and again, with different filters and zoom levels. That description says the final stretch probably repeats an earlier portion, and it does not say whether the parts separated by cuts belong to one continuous take.

The title promises more than the file: "USO" implies a submerged object, but neither the title nor the description mentions water or any maritime context. AARO's description speaks of "areas of contrast" and does not say what they are, how many there are beyond four, or how far away.

As for the four objects, the only conventional reading on record is that of an amateur French blog, OVNI 66, which in a June 2026 post titled "DOW-UAP-PR052, vol en formation de 4 PAN" holds that "one clearly perceives the wingbeat of a group of 4 birds." No official source supports it.

Documents and sources

Documented evidence

  1. Title "USO Formation" is a user label, not a Department of War designation; nothing in the title or description confirms an aquatic context
  2. Official visual description: four areas of contrast cross the frame together in the first 5 seconds (matches the title's "formation")
  3. Duration of 8:16; AARO's description records cuts between seconds 6 and 38 and between 0:39 and 6:08
  4. AARO flags multiple internal cuts and that the final segment (8:11-8:15) likely repeats an earlier portion rather than continuing chronologically
  5. AARO warns that "many of these materials" in the batch lack a substantiated chain of custody, without saying which
  6. Released in PURSUE Release 02 (uploaded to DVIDS May 22, 2026), public domain
