Why the USS Thresher SSN 593 was lost Bruce Rule?

The US nuclear submarine THRESHER (SSN-593) was lost because standard compensation procedures to adjust for hull compression during the deep-dive on 10 April 1963 were not followed.

What really sank the Thresher?

Unbeknownst to the Seawolf at the time, every major investigation has concluded that, by the time it began its first dive search, the Thresher had already been crushed by the ocean pressure after sinking to 2,400 feet — 400 feet past what its hull could take.

What happened to the submarine the Thresher?

On April 10, 1963, the USS Thresher, an atomic submarine, sinks in the Atlantic Ocean, killing the entire crew. One hundred and twenty-nine sailors and civilians were lost when the sub unexpectedly plunged to the sea floor roughly 300 miles off the coast of New England.

What was the crush depth of the USS Thresher?

around 1,300 feet
The Thresher’s fateful plunge came somewhere around 1,300 feet of depth, when its nuclear reactor shut down. The hull imploded despite efforts by the crew to blow its ballast tanks.

At what depth did the Thresher implode?

According to Rule the SOSUS data indicates an implosion of Thresher at 09:18:24, at a depth of 730 meters (2,400 ft), 120 meters (400 ft) below her predicted collapse depth. The implosion took 0.1 seconds, too fast for the human nervous system to perceive.

Was the Thresher ever recovered?

Mizar sailed on 25 June to begin the deep search and found the wreck within two days. The shattered remains of Thresher’s hull were on the sea floor, about 2,600 meters (8,400 ft) below the surface, in five major sections. Most of the debris had spread over an area of about 134,000 square meters (33 acres).

At what depth did the USS Thresher implode?

2,400 ft
According to Rule the SOSUS data indicates an implosion of Thresher at 09:18:24, at a depth of 730 meters (2,400 ft), 120 meters (400 ft) below her predicted collapse depth. The implosion took 0.1 seconds, too fast for the human nervous system to perceive.

Did they ever find the USS Scorpion?

Two months later came stunning news: On October 30, 1968, the navy announced that Mizar had found the wreckage of Scorpion. A towed sled gliding fifteen feet above the ocean floor at the end of a three-mile cable had photographed the sub’s broken hull.

Why did the USS Scorpion sink?

An apparent rupture in her pipes allowed saltwater to spray into the vessel, causing a chain reaction leading to a reactor shutdown, a failure of the air flasks used to surface, and the progressive flooding of the submarine. The Thresher sank with 129 aboard—amounting to the deadliest submarine accident ever.
