The incident took place on November 6th, 2018. It is unclear if the investigation began prior to January 21st, 2019.

The Stena line ship carries out a scheduled two and a half hour ride between Belfast and the Scottish port of Cairnyan.

The Stena Super­fast VII vessel holds 1,300 passengers and 660 motors. The Royal Navy sub was shallow enough to extend its periscope above the water’s surface.

According to the BBC, the UK Ministry of Defense refused to confirm which of its 10 submarines was involved. “All of its submarines are nuclear-powered but only four carry Trident nuclear missiles.”

BBC cited a spokesperson for the Marine Accident Investigation Branch (MAIB) who said:

“In November, we were notified of a close-quarters incident between the ro-ro (roll-on/roll-off) ferry Stena Superfast VII and a submarine operating at periscope depth. We have carried out a preliminary assessment of the evidence in this case and the Chief Inspector of Marine Accidents has decided to open a safety investigation. The investigation is being conducted with the full co-operation of the Royal Navy. A report will be published when our investigation has concluded.”

BBC also cited a Royal Navy spokesperson:

“We can confirm the sighting of a Royal Navy submarine between Belfast and Stranraer on 6 November 2018. We are co-operating with the MAIB’s investigation.”

Finally, a spokesman for Stena had the following to say:

A spokesperson for Stena said:

“Stena Line can confirm that on Tuesday 6 November 2018, Stena Superfast VII and a submerged submarine came into close proximity during a scheduled crossing between Cairnryan and Belfast. At no stage were the vessel, passengers or crew in any danger. The incident is now under investigation by the Marine Accident Investigation Branch and we will of course co-operate fully in this.”

The Marine Accident Investigation Branch (MAIB), publishes regular reports of its investigations. It is expected, and the UK Ministry of Defense confirmed that such a report would also be published regarding the incident.

These boys and girls handle a nuclear powered submarine like Prince Phillip handles a Land Rover. Stay off the cell phones and pay attention – you are not US Navy sailors. (What would Raleigh, Drake, Frobisher and Nelson say about today’s Royal Navy?)

Brother Ma

They must have had a us navy woman “in close proxinity to the helm” as the just -shipped Norwegian destroyer had. She sunk it!


Surprising this vessel out in an actual water way – this class are generally in dock for repairs.
