The US Says Iran Didn't Hit Its Drone Ship. That Part Is True.
Something came up under a Navy surface drone early on Saturday, in 74 metres of water, at a speed nothing makes submerged. The exclusion zone Tehran announced on Sunday is a nine-mile box drawn around the spot where the drone stopped.
MANAMA, Bahrain — At 23:51 Zulu on Friday a United States Navy surface drone in the outbound lane of the Strait of Hormuz went from six knots to nothing in forty seconds, and its heading swung through 140 degrees while it did.
Iranian state television said on Saturday that the Revolutionary Guard's navy had hit it. On Sunday morning Washington said that no Iranian platform had engaged the vessel.
This newspaper has spent the weekend with the drone's own track, eleven seconds of a tanker's bridge camera, the tug's log and the notice Iran put out on Sunday night. The Navy is right. Iran did not hit it.
Something came up under it from 74 metres of water. That is the finding.
The peg
The wire carried two items on Sunday, ten hours apart: the American denial, and Tehran saying it would declare an exclusion zone near the strait.
Read separately they are a denial and a provocation. Read as a pair, with the coordinates, they are one story.
The track
The drone is a thirteen-metre uncrewed catamaran of the kind Task Force 59 has run out of Bahrain since 2021. It broadcasts on the automatic identification system so that tankers do not run it down, and anyone can buy its track. We did.
At 23:14Z on Friday it left its patrol box south of Larak Island making 6.1 knots. At 23:51Z, twelve nautical miles south-south-west of Larak, in the southern lane of the traffic separation scheme, its speed fell to zero across two fixes forty seconds apart. Its heading, steady for thirty-seven minutes, swung from 248 to 028 degrees. It transmitted for sixteen more minutes from the same position and then stopped.
The chart gives 74 metres of water there. There is no shoal, no charted wreck and no pipeline within four miles.
Eleven seconds from a bridge
The product tanker Halcyon Brae, 228 metres, Marshall Islands flag, was in the same lane 1.4 nautical miles to the east, outbound for Fujairah. Her bridge camera records continuously. Her second officer, Teodora Vasquez-Lindqvist, had the watch and saw it live.
The clip shows eleven seconds of a wake crossing the lane from north to south, white on black water, with nothing at the head of it. Using the tanker's own hull as a scale, the wake covers 1.1 ship lengths in the eleven seconds. That is 44 knots.
The Revolutionary Guard operates a rocket torpedo it says makes 200 knots. A torpedo makes a wake and then a hole. There is no explosion on the clip, none on the tanker's radar overlay and none in the tow log. The wake stops where the drone stopped, and stays there.
The keel
The tug Sitra Dawn, of Gulf Salvage and Towage in Bahrain, took the drone in tow at 06:50Z on Saturday. Her master's log, which the company gave us on Sunday and which is published with this story, records the port hull's keel "deformed upward 38 cm over 2.1 m, consistent with grounding".
A boat does not ground in 74 metres of water. The keel was pushed up, not blown in, and it was pushed from below.
At 09:20Z the log records the payload removed at the pier by Task Force 59 personnel, the tug's crew sent below for the twenty minutes it took. The payload includes a hydrophone.
The library
Rosalind Achterberg-Nwosu was a chief sonar technician in the Navy for twenty-three years and made two Fifth Fleet deployments. We read her the second officer's account and the tow log and asked whether she recognised it.
She said the sound of it has been in the Navy's acoustic library since 2015, that it has a classification, and that she would not tell us what the classification was. She has been out of the Navy for five years and has never before spoken to a newspaper. We are printing that she said it and that she stopped.
The box
The notice Iran put out on Sunday night from the Bandar Abbas transmitter describes a square nine nautical miles on a side. It does not enclose Larak. It does not enclose any Revolutionary Guard base, any oil terminal or any Iranian water at all. It sits astride the southern lane of the traffic scheme, in Omani water.
We plotted its centre from the four corners in the notice. It is 300 metres from where the drone stopped. Our position came from the drone's own transmissions. Theirs came from something else.
A navy does not draw a box around a thing it hit. It draws a box around a thing it does not want anyone else to look at.
What this desk takes from it
That the American statement is true, and true in the way a statement drafted by a lawyer is true. No Iranian platform engaged the vessel. The statement does not say that nothing did.
And that the two governments on either side of the strait have, for the first time in living memory, agreed on a set of coordinates. Neither will say why.
Everything else in this story took fourteen minutes and we have eleven seconds of it. We have published the eleven seconds.

Sources & Method
We bought the drone's transmitted track, found the one ship in the lane with a camera pointed the right way and asked her second officer for the clip, got the tug's log from the salvage company that wrote it, and plotted the corners of the Iranian notice ourselves rather than reading its headline. Our correspondent worked the wake's speed from the tanker's known length, frame by frame, the way he timed aircraft for nineteen years. Written questions went to both navies. One answered.

What we could not confirm
- What it was. We have a wake without a hull, a keel bent upward in water too deep to ground in, and a retired sonar chief who says the sound has a name. We do not have the name, and nothing we hold describes a shape.
- What the hydrophone heard. The drone carried one, and the payload came off at the pier at 09:20Z in the hands of Task Force 59. The Navy will not say whether it recorded, and the tug's crew were sent below while it came off.
- How Tehran fixed its centre. Our position is from the drone's own transmissions, which Iran does not have. Its box is centred within 300 metres of our fix, which means it has a position of its own from an instrument it has not described, and nobody in Bandar Abbas will take our call.
How Others Covered This
The same events, as reported elsewhere on the same day. We list what each outlet had that we did not, as well as what we had that they did not — including where we come off worse. Why we print this.

The Continental WireUS Denies Iran Struck Uncrewed Vessel In Strait
Ran the Iranian claim and the American denial side by side and let the reader choose.
Had that we did not
Both statements, in full and accurately.
Left out
The tanker a mile and a half away with a camera running. The item does not mention that any other ship was in the lane.
-
The Hollow PostTHE NAVY IS LYING ABOUT HORMUZ
Took the denial as proof of its opposite.
Had that we did not
The tow, which it had from the port before we did.
Left out
That the denial is accurate. It says Iran did not do it. Iran did not do it, and a story built on the Navy lying has to explain why Tehran drew its box where it did.

They Buriedthis newspaperThe US Says Iran Didn't Hit Its Drone Ship. That Part Is True.
Bought the track, found the one ship with a camera pointed the right way, and read the Iranian notice's coordinates instead of its headline.
Had that we did not
Eleven seconds of footage, two positions, a bent keel and a box on a chart.
Left out
We have put That Part Is True in a headline over a story whose whole finding is that we do not know the other part. A reader is entitled to think we do. — V. Ashcombe-Doyle, standards editor
Right of Reply
They Buried contacted Commander Aurelio Stavros-Whitcombe, spokesman, US Naval Forces Central Command, Manama sent the full draft, the clip and the tow log on Sunday at 14:00Z; given until 06:00Z Monday. Replied at 04:10Z. Asked that the reply run whole rather than as a quotation. Printed unedited.
Your correspondent spent nineteen years watching tracks and he knows the difference between a track and a hull, so I am going to hold him to it.
A track is a sequence of positions. A wake is water. A keel deflection recorded by a tug master at first light is an observation and not a survey. Each of those three things is true, and you have joined them with the word something, and I would ask your readers to notice that the join is yours and not ours.
Here is what I am cleared to say, and I will say it again because it is the only thing I am cleared to say. No Iranian platform engaged the vessel. The vessel was recovered. Its payload was recovered. The data are under review. I am not going to characterise a review that has not finished, and I would be suspicious of anyone who did.
You asked whether the acoustic library carries a classification for the contact. I am not going to answer a question whose answer would tell you whether we have a library.
You asked about the Iranian notice. We are aware of it. We have not disputed its coordinates, and we would ask mariners transiting the strait to observe it until further notice, which is not a sentence I expected to write this year.
Your second officer kept a good watch and I would like that said. Your retired chief should call me, and she knows why.
