Maybe because Hyman Rickover wasn’t really the genius and visionary that’s been described to us?

I was stationed at New London on the USS Jallao (SS-368) when the Thresher went down. A very sad day.

You wonder was there a Soviet submarine running near the submarine base though....

[Repeal The 17th]

What about Scorpion?
Will we get the skinny on that one too?

Russkies.

I remember some WWII U-Boats went way deeper than their design was supposed to go. I think close to the same depth as the the Tresher.

Anyone with an interest in the subject of sunken submarines should pick up The Terrible Hours by Peter Maas; it describes the sinking of the USS Squalus and the attempt to rescue the crew. (It also describes the work of "Swede" Momsen and the "Momsen Lung", which became a critical piece of escape gear for submarine crews.)

It's riveting and easy to read.

I was on the 599 and our crush depth was nowhere near 1300 feet. It was more like 1100 and we never went below 800 on purpose.

Ice in the valves from what I remember.

I had a 1st cousin who died on the Thresher

Failure to maintain buoyancy is my guess

The Navy lost another submarine, the USS Scorpion, in 1968

Well, that one was likely sunk by the Soviets.

I was a young girl when that happened and I remember it like it was yesterday. So sad. I was in the newspapers for weeks it seemed like....

From what has leaked out over the years, there were multiple faults in the Thresher's design and construction: poor quality brazing on internal pipes led to joint failures and flooding; a shorting out of electrical power followed due to saltwater leaks; there was an inability to access emergency equipment; and then, fatally, a buildup of ice on ballast tank valves and pipes led to a failure of the ballast tank blow that ought to have saved the boat.

Changes were made long ago to remedy those defects. Why the enduring Navy coverup? The report likely revealed numerous other defects and to systemic lapses in leadership that should have led to the removal of Rickover and other Navy brass, a restructuring of the Navy's shipbuilding process, and with penalties and reforms for the shipbuilders.

As it was, Rickover skated until his improper and cozy relationship with the Navy's ship contractors forced him into retirement. Since the Navy's shipbuilding process remains troubled today, those now in charge do not want an old sub loss report becoming public and helping to spur reforms.
