US Navy decommissioned USS Pittsburgh (SSN-720) Los Angeles submarines

The US Navy decommissioned the USS Pittsburgh (SSN-720) Los Angeles-class nuclear submarine. Farewell ceremony with the submarine was held at the Museum of the Underwater fleet USA in Capeport, Washington. It is reported by Defense Blog.

According to the command of the U.S. Navy, the state flag was lowered on the submarine, they officially stopped duty and turned off the submarine. Then the nuclear submarine will be transferred to the Puget Sound shipyard for the dismantling of classified equipment, weapons and a reactor.

The USS "Pittsburgh" multipurpose nuclear submarine (SSN-720) is the 33 in the series of 62 Los Angeles-class submarines built for the US Navy. Introduced into the US Navy 23 November 1985 of the year. Home Port Naval Base Groton.

Displacement above sea level 5895 tons, underwater 6292 tons. 110,3 meter length, 10 meter width, 9,4 meter draft. The speed above the 20 nodes, the official submarine more than 20 nodes. Operating depth from 250 to 280 meters. Extreme depth of immersion 450 meters. Crew 12 officers, 98 sailors.

Powerplant: S6G nuclear reactor. Armament: 4 × 21 in (533 mm) torpedo tubes; Tomahawk 12 missiles in vertical launch mines.

In September 2018, a submarine leaked water in the reactor compartment, which led to the forced return of the submarine to the home port at the Groton Naval Base (Connecticut) to fix the "malfunction". A leak was located near the valve of a nuclear power plant and was discovered during a routine check.

on the submarine they lowered the state flag, officially stopped watch keeping and de-energized the submarine

It’s not entirely clear that no one is following the reactor? And how could it be completely de-energized?

As usual .. the cable from the shore was chopped off ..

[K-612-O]

From external power supply, from the pier. Most likely, the reactor was shut off after the accident.
Although it is muffled by anyone before decommissioning.

[Thrifty]

It seems not old! Do not want to repair and deactivate, after a nuclear leak on board?

[TermNachTer]

Hrenasenki - not old. 35 year olds, how many patrols? Again, it is not known how serious the accident was. Perhaps the repair just did not make sense.

[FORCE 38GB]

Served her .. And retired. It's quite normal. The nuclear-powered ship is 35 years old ... It would be high time for some to retire too .. And not only nuclear submarines, but also SSBNs .. The same squids with dolphins .. If only "Ash" with "Boreas" to replace them according to the plans kept up. ...

Minus one .. A trifle, but nice

Yeah. If "minus one" - maybe it would be nice. That's just to replace this one, withdrawn on April 4, they will raise the flag on the Delover (SSN-791), and on April 18 on the Vermont (SSN-792)
"Minus" one "plus" two will give "plus" one

This is not about the current submarine fleet of the U.S. Navy. Yes, and in general, who is good now in this regard? China has gained a good tempo, but this is true only for surface ships, the same destroyers.

The Russian fleet includes 62 submarines of all classes, including 10 atomic submarines with ballistic missiles, 9 atomic submarines with cruise missiles, as well as 14 nuclear and 22 conventional attack submarines.

However, many of them were produced in the 1980-1990s. According to experts, the operation of submarines older than 35 years is inefficient and unsafe.

“If Moscow succeeds in producing all the Boreas and Ash trees that it plans, the total submarine fleet can reach only 28 boats. Half of its current strength, ”the article says.

Axx points out that the Americans produced a large number of submarines during the Cold War, but the current construction cannot satisfy the modern needs of the fleet.

“In December 2016, the U.S. Navy announced that they needed 66 submarines with strike and cruise missiles. But at the beginning of 2019, the fleet had only 51 strike ships. And this number is predicted to decrease, ”the expert writes.

According to him, dozens of Los Angeles-class submarines will be decommissioned in the next few years, and too few new Virginia-class submarines will be produced.

Raising the flag is not an option for military patrols. More than one month will pass.

They removed the watch, and will remove the secret equipment THEN. To go, or to twist something thread there? Who's gouging, scribble or warriors?

Any ships finish their service journey.
Rest in peace. Better so than to disappear, having fulfilled your destiny.

[Kerensky]

Our neighbors have already asked her for free? Who is monitoring Ukrainian resources? This is not an inflatable, but the real one! Weld with solid rails to the pier - so there will be no price!

This is not about going out on combat patrols, but about joining service. Therefore, I wrote that "MINUS ONE - PLUS TWO"

You can soon wait for her in the Black Sea under the name "Hetman Mazepa" for example ....

And nothing that the Black Sea is a nuclear-free zone. And that during the Olympics, even our "Peter the Great" could not enter the World Cup to support the Olympics?

The power cables are disconnected from the CPS drives, all of them, i.e. the absorbers are located at the bottom of the core. The reactor is reliably shut down and cooled down, i.e. the temperature of the primary circuit does not even require periodic starting of the pumps for residual heat. The high pressure gas, high pressure gas (nitrogen) is unloaded and disconnected from the volume expansion joints. There is no longer a need to maintain a pressure of about 1 kg in 200 circuit. Helium is vented from the AR rod covers. For longer storage while waiting for the fuel unloading queue and the complete exclusion of a terrorist attack, the CPS drives can be completely dismantled, and their heads can be scalded. Secret documentation is being leased, a lock is hung on the control panel of the power plant, and the operators with Kipovtsy go off to smoke bamboo.

CPS drives can be completely dismantled, and their heads are scalded. Ill, not.

less trash in the sea-ocean, but I don’t believe in conservation, it’s expensive to store ...
