“U.S. 5th Fleet Reveals New Details on Iranian Drone Attack on Tanker” –USNI

The US Naval Institute has a post providing addition detail about the November 15  drone attack on tanker Pacific Zircon.

The primary thrust of the post seems to be, to confirm that the drone was of Iranian origin, but then, that was almost assumed. They seem to have proven that, identifying it as a Shahed-136 design, a “loitering munition.”

For me the new information was where the tanker was targeted and the extent of the resulting damage.

When I first heard that this drone had hit the hull, I thought perhaps the Iranians had decided it was not to their advantage to kill crew members, as had happened in the July 30 attack on the tanker Mercer Street, but apparently that was not the case, since this strike was also on the stern where it is more likely to effect crewmembers.

As to the weapon’s effect, the Shahed–136 reportedly has a 30–50 kilograms (66–110 lb) warhead. referencing a 5th Fleet report, USNI notes,

On Nov. 15, a Shahed 136 explosive-tipped drone flew into the aft section of the merchant oil tanker M/T Pacific Zircon punching a hole through the hull, “while subsequently penetrating and damaging internal compartments. The UAV’s explosive impact also damaged a shipboard boiler, potable water tank and life raft,” reads the statement.

That they managed to damage engineroom equipment, which presumably required penetration of multiple internal bulkheads, after penetrating the hull, is more than I would have expected. The anti-armor, shaped charge version of the munition, which would result in a narrowly focused path of destruction, may have been used.

“U.S. Blames Iran for Drone Attack on Tanker Near Oman” –USNI

US Naval Institute’s News Service reports,

U.S. Central Command and Israeli officials are blaming Iran for a Tuesday attack on an oil tanker linked to an Israeli billionaire off the coast of Oman.

Tanker Pacific Zircon was 150 miles off the coast of Oman when what U.S. officials said was an unmanned aerial vehicle hit the ship at about 3:30 p.m. local time, according to the shipping company.

Interestingly this second attack was on a ship linked to Idan Ofer, brother of the Israeli billionaire, Eyal Ofer, linked to the tanker, Mercer Street, attacked in a similar manner in July 2021.

The latest attack did not result in any injuries, unlike the earlier attack that resulted in the death of two crewmembers. Both attacks occured South of Oman in the Northern Indian Ocean.

The Ukrainian gunboat seems to have been pretty well armed.

We have talked about Loitering Munitions before:

These could be the answer to the Coast Guard’s need to be able to defeat small, highly manueverable, high speed surface threats.

They also extend the range at which non-state actors might be able to engage Coast Guard units.
