A story of major underwater disasters – gCaptain

April 22 (Reuters) – The Indonesian Navy is searching for its KRI Nanggala-402 submarine after losing contact with the ship in waters off Bali on Wednesday. Here are some other notable underwater accidents:

Losharik fire

In July 2019, a fire aboard the Russian nuclear-powered deep-water research submarine Losharik killed 14 crew members. Five of those on board survived, according to reports, and the submarine was recovered and repaired.

ARA San Juan lost

The Argentine diesel-electric submarine went missing on patrol in November 2017. After weeks of search and rescue efforts, it was declared lost along with all 44 people on board. His wreck was discovered the following year in about 900 meters of water.

Kursk disaster

On August 12, 2000, the Russian guided-missile submarine K-141 Kursk sank to the bottom of the Barents Sea after two explosions with its bow. All 118 men aboard the nuclear-powered submarine died. After recovering the remains of the dead from the submarine, officials determined that 23 crew members, including the commander of the Kursk, survived the initial crash before suffocating.

Sinking of the K-8

A fire that broke out aboard the Soviet attack submarine K-8 on April 8, 1970 deactivated the nuclear-powered vessel in the Bay of Biscay, forcing the crew to abandon the ship. The crew re-boarded the submarine after the arrival of a rescue vessel. But the submarine sank while being towed through rough seas, taking 52 submariners with it.

Scorpio disappears

In May 1968, the US Navy’s nuclear-powered attack submarine Scorpion went missing in the Atlantic Ocean with 99 men on board. The wreckage was found in October about 644 km southwest of the Azores Islands, more than 10,000 feet (3,050 meters) below the surface. There have been several theories for the disaster: the accidental release of a torpedo that turned around and struck the Scorpion, an explosion of the submarine’s enormous battery, or even a collision with a Soviet submarine. .

The sinking of the K-129

The K-129, a nuclear-powered Soviet ballistic missile submarine, sank on March 8, 1968 in the Pacific Ocean, taking the 98 crew with it. The Soviet Navy failed to locate the ship. A US Navy submarine found it northwest of the Hawaiian island of Oahu at a depth of about 16,000 feet (4,900 meters). An offshore drilling vessel, the Hughes Glomar Explorer, was able to recover part of the submarine in a covert operation. The remains of six Soviet crew members found in the submarine were buried at sea.

The implosion of the thresher

On April 10, 1963, the US Navy’s nuclear powered attack submarine Thresher was lost with all 129 men on board. The submarine shattered in 8,400 feet (2,560 meters) of water during deep dive testing southeast of Cape Cod, Massachusetts. According to US military analyzes of the accident, the most likely explanation is that a pipe joint in an engine room seawater system failed, bypassing the electronics and causing the engine to shut down. reactor of the ship which left it without sufficient power to prevent itself from sinking.

K-19 nuclear accident

The K-19, one of the first two Soviet nuclear ballistic missile submarines, had been plagued by breakdowns and accidents before launch. On its first voyage, July 4, 1961, the submarine suffered a complete loss of coolant in its reactor off the southeast coast of Greenland. The ship’s engineering crew sacrificed their lives to install an emergency cooling system by a jury. Twenty-two of the 139 men on board died from radiation exposure. The remaining 117 suffered from varying degrees of radiological illness. The crash was portrayed in the 2002 film “K-19: The Widowmaker”.
