On 17 December 1917, USS F-1 collided with its sister ship, USS F-3, off the coast of San Diego during a training exercise in dense fog. The impact caused the F-1 to sink within ten seconds, resulting in the loss of 19 crew members. A mere five sailors survived the incident. The submarine now rests approximately 1,300ft (~396m) beneath the Pacific Ocean.

Dutch WWII Submarine Located off Australia

The wreck was found 40 metres deep, approximately 7.8 nautical miles south of Rottnest Island, by divers investigating a sonar anomaly on 1 January 2025.

A historic vessel

Built in 1925 for the Royal Netherlands Navy, K XI was one of the first submarines designed for long-range patrols in the Netherlands East Indies (NEI). During World War II, the vessel was relocated to Fremantle, Australia, where it played a role in Allied submarine operations in the Pacific theatre.

British WWII Sub Found Off Norway

The waters off the coast of Norway have unveiled a long-hidden secret. The wreckage of the British submarine HMS Thistle, which sank during World War II, has been discovered after 83 years. The discovery was made by Norway's Institute of Marine Research and the MAREANO program during a routine seabed mapping cruise. The submarine's identification was confirmed only recently, following a subsequent cruise.

The HMS Thistle embarked on its final voyage on 10 April 1940. Tragically, it was torpedoed by a German submarine, leading to the loss of all 53 crew members on board.

British WWII submarine located in the Aegean Sea

Kostas Thoctarides told state news agency ANA his team had located the wreck of HMS Triumph at a depth of 670 feet at an undisclosed location in the Aegean Sea.

The HMS Triumph was a British T-Class submarine involved in military operations in the Aegean Sea and elsewhere in the European theatre of the Second World War. It carried out twenty missions, including attacks against Axis ships, landing British commandos and rescuing Allied soldiers, until it disappeared during a mission in 1942. Eighty-four submariners were killed when the HMS Triumph sank.

USS Albacore
A row of vent holes along the top of the superstructure, and the absence of steel plates along the upper edge of the fairwater allowed NHHC’s Underwater Archaeology Branch (UAB) to confirm the wreck site finding as Albacore.

The US Naval History and Heritage Command (NHHC) confirmed the identity of a wreck site off the coast of Hokkaido, Japan, as USS Albacore (SS 218). The NHHC made the announcement on Thursday, after several months of examining Japanese surveys conducted on the site in 2022.

Russian mini-sub found in Swedish waters is 100 years old

Sweden's military has now analyzed the video footage provided by Swedish wreckhunter group Ocean X Team and concluded that it is the wreck of a Russian submarine that sank after a collision with a Swedish vessel in 1916 during the First World War. Ocean X was the team who also found the "Baltic anomali"

HMS Regent, long lost WW2 submarine, found in the Adriatic

The newly-found wreck lies off the coast near Villanova di Ostuni, some 19 miles from Monopoli.

First believed to be found by Italian divers in 1999, it was later determined in 2020 that the wreck thought to be Regent was in fact the Italian submarine Giovanni Bausan which had been sunk by the RAF in 1944.

Now, it seems another dive team has had better luck in identifying Regent. She rests off the coast near Villanova di Ostuni, some 19 miles from Monopoli, upside down in 70m of water. The apparent victim of a mine.
