On Monday, an American submarine docked in the Port of Grøtsund, Tromsø. The US destroyer Thomas Hudner has also recently docked at a port in this city. Perhaps the submarine is, as the destroyer, part of the US Gerald R. Ford Carrier Strike Group.
On Monday, the port of Grøtsund north of Tromsø, Northern Norway, was visited by an American submarine. The Norwegian Joint Headquarters confirmed that the submarine belongs to the US Navy, but does not state its name or which class it belongs to, writes NRK.
On Monday morning, one could sense such a visit by following the sea chart Marine Traffic as three Norwegian military vessels sailed in Grøtsund and the surrounding area. These were the corvette KNM Oddane, a MOB boat, and a RIB boat. Tugboats were also in the area.
This is the tenth reported US submarine call at Grøtsund, which was made a port of call for allied nuclear-powered vessels in Norway in 2020 (see overview below). Here they can get new supplies, change crews, and carry out other administrative tasks.
In April, the Norwegian Radiation and Nuclear Safety Authority said to High North News that a doubling of the number of allied submarines in Norway is expected – respectively to the Port of Grøtsund and Haakonsvern in Bergen. (Norwegian only)
Also a destroyer in Tromsø
At the same time as the submarine visit, the American destroyer USS Thomas Hudner was apparently still docked in the district of Breivika in Tromsø, according to AIS data from Marine Traffic. It called the city on Wednesday after sailing further north outside the Finnmark coast on Tuesday.
The destroyer is among the accompanying vessels of the US' (and the world's) largest aircraft carrier, the USS Gerald R. Ford.
In the first half of June, the Gerald R. Ford Carrier Strike Group conducted several training activities with Norwegian and British forces in Northern Norway – primarily in the Vestfjord, Nordland county.
Perhaps the aforementioned submarine is also part of this group.
The USS Gerald R. Ford has sailed from Norway, said the Norwegian Armed Forces on Friday, but several of its accompanying vessels have appeared to have taken some 'detours' since the group left Norfolk Naval Station in the US on the 2nd of May.
Including this latest visit, there has been a total of 10 known calls by American nuclear submarines at the Port of Grøtsund.
- USS New Mexico (SSN 779), Virginia class – May 2021
- USS Washington (SSN 787), Virginia class – January 2022
- USS Albany (SSN 753), Los Angeles class – April 2022
- USS North Dakota (SSN 784), Virginia class – Mai 2022
- Uknown American submarine – July 2022
- USS Newport News (SSN 750), Los Angeles class – Fall 2022
- USS New Hampshire (SSN 778), Virginia class – Fall 2022
- USS South Dakota (SSN 790), Virginia class – December 2022
- Uknown American submarine – April 2023
- Uknown American submarine – June 2023
In addition, the British nuclear submarine HMS Ambus visited Grøtsund in April 2022. This was the first visit by a British submarine to the port.
The variation in time stamps in the overview above is due to how the US Navy first reports its submarines' port calls in Tromsø and other places after they have returned home to its home bases after several months-long voyages.
The submarine classes
The Los Angeles class consists of nuclear-powered fast attack submarines and form the backbone of the American submarine forces, according to the US Navy. Of around 40 in operation, 30 are equipped with twelve Vertical Launch System tubes for firing Tomahawk cruise missiles. They are also equipped with torpedoes or anti-ship missiles.
The Virginia class also includes nuclear-powered fast attack submarines. This is the US Navy's new generation of submarines with several innovations – and 21 of these are now in operation. These are designed for a wide specter of sea and coast missions and will eventually replace the submarines of the former class. They are also equipped with Tomahawk cruise missiles, torpedoes and anti-ship missiles.
The attack submarines are made for the following tasks: search for and destroy enemy submarines and surface ships, project power ashore with Tomahawk missiles and Special Operation Forces, conduct intelligence, surveillance, and reconnaissance missions – as well as support battle group operations and engage in mine warfare.
Other recent submarine voyages
American nuclear submarines have also recently visited Arctic islands in Northern Europe.
In the middle of May, the Faroese government reported a visit by the USS New Mexico to the Nólsoyarfjörður strait in connection with a crew change.
In April, American submarines received permission to make service calls to Iceland. The first submarine visit was by USS San Juan, which made a short stop off the island's southwest coast at the end of the same month.
