The Monument to the Sunken Ships, dedicated to ships destroyed during the siege of Sevastopol during the Crimean War, designed by Amandus Adamson

A ship is scuttled when its crew deliberately sinks it, typically by opening holes in its hull.[1]

Scuttling may be performed to dispose of an abandoned, old, or captured vessel; to prevent the vessel from becoming a navigation hazard; as an act of

self-destruction to prevent the ship from being captured by an enemy force; as a blockship to restrict navigation through a channel or within a harbor; to provide an artificial reef
for divers and marine life; or to alter the flow of rivers.

Notable historical examples

Skuldelev ships (around 1070)

The Skuldelev ships, five Viking ships, were sunk to prevent attacks from the sea on the Danish city of Roskilde. The scuttling blocked a major waterway, redirecting ships to a smaller one that required considerable local knowledge.[2]

Cog near Kampen (early 15th century)

In 2012, a cog preserved from the keel up to the decks in the silt was discovered alongside two smaller vessels in the river IJssel in the city of Kampen, in the Netherlands.[3] The ship, dating from the early 15th century, was suspected to have been deliberately sunk into the river to influence its current.[4][5]

Hernán Cortés (1519)

The Spanish conquistador Hernán Cortés, who led the first expedition that resulted in the fall of the Aztec Empire, ordered his men to strip and scuttle his fleet to prevent the secretly planned return to Cuba by those loyal to Cuban Governor Diego Velázquez de Cuéllar. Their success would have halted his inland march and conquest of the Aztec Empire.

HMS Sapphire (1696)

HMS Sapphire was a 32-gun, fifth-rate sailing frigate of the Royal Navy in Newfoundland Colony to protect the English migratory fishery. The vessel was trapped in Bay Bulls harbour by four French naval vessels led by Jacques-François de Brouillan. To avoid its capture, the English scuttled the vessel on 11 September 1696.

HMS Endeavour (1778)

HMS Endeavour was Captain James Cook's ship upon which he travelled to Australia. After being sold into private hands, she was finally scuttled in a blockade of Narragansett Bay, Rhode Island in 1778.

Siege of Yorktown (1781)

The British sank one ship on 10 October 1781 to prevent it from being captured by the French fleet. Furthermore, the York River, while protected by the French Navy, also contained a few scuttled ships, which were meant to serve as a blockade should any British ships enter the river.

HMS Bounty (1790)

HMS Bounty, after her crew mutinied, was scuttled by the mutineers in Bounty Bay off Pitcairn Island on 23 January 1790.

Chesapeake Bay Flotilla (1814)

During the War of 1812, Commodore Joshua Barney, of the U.S. Navy, Chesapeake Bay Flotilla, sank all nineteen of his fighting vessels, to prevent them from being captured by the British, as he and his men marched, inland, in the unsuccessful defense of Washington D.C.

Jan van Speijk (1831)

During the

Jan van Speijk
came under attack from a mob of Antwerp labourers. When they forced him and his crew to surrender, he ignited a barrel of gunpowder, thereby sinking his ship and killing himself and most of the crew. Van Speijk went on to become a national hero in the Netherlands.

Russian Black Sea Fleet in Sevastopol (1854)

A sunken ship at Sevastopol, 1858

During the Crimean War, in anticipation of the siege of Sevastopol, the Russians scuttled ships of the Black Sea Fleet to protect the harbour, to use their naval cannon as additional artillery, and to free up the ships' crews as marines. Those ships that were deliberately sunk included Grand Duke Constantine, City of Paris (both with 120 guns), Brave, Empress Maria, and Chesme.

The Clotilda

The Clotilda (slave ship) (often misspelled Clotilde) was the last known U.S. slave ship to bring captives from Africa to the United States, arriving at Mobile Bay, in autumn 1859 or on July 9, 1860, with 110 African men, women, and children. The ship was a two-masted schooner, 86 feet (26 m) long with a beam of 23 ft (7.0 m). U.S. involvement in the Atlantic slave trade had been banned by Congress through the Act Prohibiting Importation of Slaves enacted on March 2, 1807 (effective January 1, 1808), but the practice continued illegally, especially through slave traders based in New York in the 1850s and early 1860. In the case of the Clotilda, the voyage's sponsors were based in the South and planned to buy Africans in Kingdom of Whydah, Dahomey. After the voyage, the ship was burned and scuttled in Mobile Bay in an attempt to destroy the evidence.

USS Merrimack/CSS Virginia (1861)

In April 1861, the

in March 1862, the Confederates scuttled Virginia to keep her from being captured by Union forces.

Stone Fleet (1861–1862)

In December 1861 and January 1862, Union forces scuttled a number of former whalers and other merchant ships in an attempt to block access to Confederate ports during the American Civil War. Loaded with stone before being scuttled, the scuttled ships were known as the "Stone Fleet." Those scuttled in December 1861 sometimes are called the "First Stone Fleet," while those sunk in January 1862 sometimes are termed the "Second Stone Fleet."

Peruvian fleet at El Callao (1881)

During the

Germán Astete
ordered the whole Peruvian fleet to be scuttled to prevent capture by Chile.

USS Merrimac (1898)

Port Arthur (1904–1905)

In 1904, during the

Port Arthur, Manchuria, China, by scuttling transports. Although the Japanese scuttled five transports on 23 February, four on 27 March, and eight on 3 May, none of the attacks succeeded in blocking the entrance.[6] The Russians also scuttled four steamers at the entrance in March 1904 in an attempt to defend the harbor from Japanese intrusion.[7]

During the siege of Port Arthur, the Russians scuttled the surviving ships of their Pacific Squadron that were trapped in port at Port Arthur in late 1904 and early January 1905 to prevent their capture intact by the Japanese.

SMS Dresden (1915)

In December 1914, SMS Dresden was the only German warship to escape destruction in the Battle of the Falkland Islands. She eluded her British pursuers for several more months, until she put into Más a Tierra in March 1915. Her engines were worn out and she had almost no coal left for her boilers. There, she was trapped by British cruisers, which violated Chilean neutrality and opened fire on the ship. Dresden's Executive Officer – the future Admiral Wilhelm Canaris – negotiated with the British and bought time for his crew to scuttle the Dresden.

Zeebrugge Raid (1918)


port of Bruges-Zeebrugge from which German U-boat operations threatened British shipping. Thetis, Intrepid and Iphigenia
were filled with concrete then sent to block a critical canal. Heavy defensive fire caused the Thetis to scuttle prematurely; the other two cruisers sank themselves successfully in the narrowest part of the canal. Within three days, however, the Germans had broken through the western bank of the canal to create a shallow detour for their submarines to move past the blockships at high tide.

German fleet at Scapa Flow (1919)

SMS Hindenburg at Scapa Flow

In 1919, over 50 warships of the

German High Seas Fleet were scuttled by their crews at Scapa Flow in the north of Scotland, following the deliverance of the fleet as part of the terms of the German surrender. Rear Admiral Ludwig von Reuter ordered the sinkings, denying the majority of the ships to the Allies. Von Reuter was made a prisoner-of-war in Britain but his act of defiance was celebrated in Germany. Though most of the fleet was subsequently salvaged by engineer Ernest Cox
, a number of warships (including three battleships) remain, making the area very popular amongst undersea diving enthusiasts.

Washington Naval Treaty (1922)

Under the terms of the Washington Naval Treaty of 1922, the great naval powers were required to limit the size of their battlefleets, resulting in the disposal of some older or incomplete capital ships. During 1924 and 1925, the treaty resulted in the scuttling of the Royal Australian Navy battlecruiser HMAS Australia and the incomplete Imperial Japanese Navy battleship Tosa, while four old Japanese battleships, the Royal Navy battleship HMS Monarch, and the incomplete United States Navy battleship USS Washington (BB-47) all were disposed of as targets.

Admiral Graf Spee (1939)

Following the

pocket battleship Admiral Graf Spee sought refuge in the port of Montevideo. On 17 December 1939, with the British and Commonwealth cruisers HMS Ajax, HMS Cumberland, and HMNZS Achilles waiting in international waters outside the mouth of the Río de la Plata, Captain Hans Langsdorff
sailed Graf Spee just outside the harbour and scuttled the vessel to avoid risking the lives of his crew in what he expected would be a losing battle. Langsdorff shot himself three days later.

San Giorgio at Tobruk (1941)

When British and Commonwealth land forces attacked Tobruk on 21 January 1941, the Italian cruiser San Giorgio turned its guns against the attacking force, repelling an attack by tanks. As British forces were entering Tobruk, San Giorgio was scuttled at 4:15 AM on 22 January. San Giorgio was awarded the Gold Medal of Military Valor for her actions in the defence of Tobruk. The ship was salvaged in 1952, but while being towed to Italy, her tow rope failed and she sank in heavy seas.

Blockade of Massawa (1941)

As the Allies advanced toward

East African Campaign in World War II, Mario Bonetti—the Italian commander of the Red Sea Flotilla based at Massawa—realized that the British would overrun his harbor. In the first week of April 1941, he began to destroy the harbor's facilities and ruin its usefulness to the Allies. Bonetti ordered the sinking of two large floating dry docks and supervised the calculated scuttling of eighteen large commercial ships in the mouths of the north Naval Harbor, the central Commercial Harbor and the main South Harbor. This blocked navigation in and out. He also had a large floating crane scuttled. These actions rendered the harbor useless by 8 April 1941, when Bonetti surrendered it to the British. Scuttled ships included the German steamers Liebenfels, Frauenfels, Lichtenfels, Crefeld, Gera and Oliva. Also scuttled were the Italian steamers Adua, Brenta, Arabia, Romolo Gessi, Vesuvio, XXIII Marzo, Antonia C., Riva Ligure, Clelia Campenella, Prometeo and the Italian tanker Giove. The largest scuttled vessel was the 11,760-ton Colombo, an Italian steamer. Thirteen coastal steamers and small naval vessels were also scuttled.[8][9][10]

The British seized the harbor and initiated

hold. Another danger was Regia Marina minelayer Ostia, which had been sunk by the Royal Air Force with several of its mines still racked. On 8 May 1942, SS Koritza, an armed Greek steamer, had drydocked for cleaning and minor hull repairs. Massawa's first major surface fleet "customer" was HMS Dido, which needed repairs to a heavily damaged stern in mid-August 1942, the beginning of a repair and maintenance period for the war-weary 15th Cruiser Squadron.[12] Many of the harbor's sunken ships were patched by Ellsberg's divers, refloated, repaired and taken into service.[13] Ostia and Brenta were successfully salvaged, despite their armed mines. All of this occurred while the British civil contractor struggled and failed to refloat one ship.[9]

Bismarck (1941)

In 1941, the battleship Bismarck, heavily damaged by the Royal Navy, leaking fuel, listing, unable to steer and with no effective weapons, but still afloat and with engines running, was scuttled by its crew to avoid capture. This was supported by survivors' reports in Pursuit: the Sinking of the Bismarck, by Ludovic Kennedy, 1974 and by a later examination of the wreck itself by Dr. Robert Ballard in 1989. A later, more advanced examination found torpedoes had penetrated the second deck, normally always above water and only possible on an already sinking ship, thus further supporting that scuttling had made the final torpedoing redundant.[14]

Coral Sea and Midway (1942)

After the Battles of the Coral Sea and Midway, the heavily damaged American aircraft carrier Lexington and the Japanese carriers Hiryū, Sōryū, Akagi, and Kaga were all scuttled to prevent their preservation and use by their respective enemies.

French fleet at Toulon (1942)

In November 1942, in an operation codenamed

1940 Armistice with Germany

Danish fleet (1943)

Anticipating a German seizure of all units of the Danish Navy as part of Operation Safari, mostly in Copenhagen but also at other harbours and at sea in Danish waters, the Danish Admiralty had instructed its captains to resist, short of outright fighting, any German attempts to assume control over their vessels, by scuttling if escape to Sweden was not possible and suitable preparations were made. Of the fifty-two vessels[15] in the Danish Navy on 29 August, two were in Greenland, thirty-two were scuttled, four reached Sweden and fourteen were taken undamaged by the Germans. Nine Danish sailors lost their lives and ten were wounded. Subsequently, major parts of the Naval personnel were interned for a period.

Allied landing in Normandy (1944)

Old ships code-named "Corn cobs" were sunk to form a protective reef for the

Arromanches and Omaha Beach for the Normandy landings
. The sheltered waters created by these scuttled ships were called "Gooseberries" and protected the harbours so transport ships could unload without being hampered by waves.

Operation Deadlight (1945–1946)

on 12 June 1945

Of the 156 German

North Atlantic Ocean west of Ireland, but 56 of the submarines sank before reaching the designated areas due to their poor material condition. Most of the submarines were sunk by gunfire rather than with explosive charges. The first sinking took place on 17 November 1945 and the last on 11 February 1946.[16][17]

Japanese submarines (1946)

To prevent a

Operation Road's End, in which it scuttled 24 of the submarines in the East China Sea off Fukue Island on 1 April 1946. Nine more Japanese submarines followed on 5 April, and another six went down by early May. In addition, U.S. Navy submarines sank four surrendered Japanese submarines as targets in the Pacific Ocean near Hawaii in May and June 1946, and the Royal Australian Navy sank six or seven (sources differ) surrendered Japanese submarines in the Seto Inland Sea on 8 May 1946 in Operation Bottom

Contemporary era

Today, ships (and other objects of similar size) are sometimes sunk to help form

war games, or for various other experiments. As an example, the decommissioned aircraft carrier USS America was subjected to surface and underwater explosions in 2005 as part of classified research to help design the next generation of carriers (the Gerald R. Ford class
), before being sunk with demolition charges.

Ships are increasingly being scuttled as a method of disposal. The economic benefit of scuttling a ship includes removal of ongoing operational expense to keep the vessel seaworthy. Controversy surrounds the practice. Notable actions against the practice include the

resident action groups aired concerns about possible impact on the area's tides and that the removal of dangerous substances from the ship was not thorough enough.[19] Further cleanup work on the hulk was ordered, and despite further attempts to delay, Adelaide was scuttled on 13 April 2011.[20][21]

Scuttled ships have been used as conveyance for dangerous materials. In the late 1960s, the

In Somalian waters,

pirate ships
captured are scuttled. Most nations have little interest in prosecuting the pirates, thus this is usually the only repercussion.

In March 2022, Ukraine was forced to scuttle the Ukrainian frigate Hetman Sahaidachny, a Krivak-class frigate, due to encroaching Russian offensive operations that threatened to capture the frigate.[23]

In February 2023, the

Federal Public Ministry.[24]

In popular culture

The term "scuttling" is also used in science fiction to describe intentionally destroying a spacecraft. For example, in The Expanse, this is done by intentionally overloading the ship's reactor.[25]

In the 13th episode of

Bob’s Burgers 12th season, Teddy and the family attend a scuttling ceremony for the USS Gertrude Stein
, the ship Teddy worked on during his Navy service.
