The remains of the USCG Cutter Tampa have been located off the coast of Cornwall, more than a century after the vessel was sunk during World War I.

The cutter was lost in September 1918 after being torpedoed by a German U-boat while escorting a convoy in the Bristol Channel. All 131 crew members on board were killed, making it the deadliest loss in U.S. Coast Guard history.

The discovery was made in autumn 2025 by the Swedish Navy vessel HMS Belos during an exercise, and has now emerged as one of the most interesting marine archaeological finds in Sweden in recent years.

Dated to the late 16th century

Following initial analyses, researchers have established that the wreck was probably built in the late 16th century. The findings are based on dendrochronological analyses of wood samples, a method that facilitates high-precision dating of timber.

The discovery, announced by the Viking Ship Museum, confirms the location of one of Denmark’s most historically significant warships, more than two centuries after it was destroyed during the naval battle on 2 April 1801.

The Dannebroge served as a Danish flagship during the battle, part of the wider conflict between Denmark-Norway and the British Royal Navy. During the engagement, the ship caught fire under heavy bombardment before eventually exploding, with heavy loss of life.

Archaeologists uncovered the remains of six historic shipwrecks in Varberg, Sweden, during investigations associated with the construction of a railway tunnel. These vessels, dating from the Middle Ages to the 17th century, were located along the town’s original shoreline and harbour area, providing new insights into centuries of maritime activity.

The proposed sinking of the SS United States has generated significant debate, with campaigners asserting that the ship constitutes a unique element of maritime heritage that warrants preservation.

The vessel, formerly the fastest transatlantic liner ever constructed, has been the focus of redevelopment initiatives for several years. Recently, proposals have surfaced to deliberately sink the ship to establish an artificial reef and diving attraction.

The discovery of a 2,000-year-old shipwreck in the depths of Lake Neuchâtel offers new perspectives on inland water transport during the Roman period. The vessel, located in deep freshwater, has remained largely intact, keeping both cargo and structural elements.

Recovered artefacts include wooden components, metal fittings, and items potentially related to transport or ceremonial functions, such as parts associated with a Roman chariot. The preservation of these materials is rare and provides important evidence of regional craftsmanship and supply practices.

The wreck of the iron steamship City of Hobart has been identified off the Gippsland coast in Victoria, Australia, resolving a maritime mystery that endured for more than a century. Technical divers from Southern Ocean Exploration (SOE) confirmed the wreck’s identity after revisiting a site detected during offshore wind-farm seabed surveys.

The discovery followed years of intermittent search efforts by researchers and divers seeking to locate the long-lost vessel.

New measures aimed at protecting historic shipwrecks along England’s southwest coast are being introduced as authorities seek to address the growing problem of heritage crime at sea.

The initiative builds on guidance developed by Historic England and partner organisations to improve how agencies detect and respond to illegal activity on underwater heritage sites.

A proposed amendment in the United Kingdom’s Armed Forces Bill 2026 could expand legal protection for military shipwrecks in British waters, potentially affecting how divers explore many historic wreck sites around the UK coast.

The proposal, contained in Clause 47 of the bill, would amend the Protection of Military Remains Act 1986 to include vessels that sank while in military service, extending legal safeguards that currently apply only to specifically designated wrecks.
