I just started to think how could I repair a submarine with damaged front end.

IT is quite nasty actually.

The biggest issue is not the sonar, that is relativly easy (but not cheap) to replace.

The real issue is the pressure vessel front.

The subrmaine pressure vessel wall needs to be within a very tight tolerance, 10mm deviation from the ideal cylinrical/spherical shape means the sub can dive to 50 meter instead of 500.


Now, if the collision deformed the front bulkhead, then they needs to check preciselly the shape of the front, and if it is deformed then they have to cut off the front section ,and replace it .

Considering that this ship is 26 years old, and the manufacturer needs to re-learn the sub, it will be very expensive and long.

Very high chance for the scrapping.

IF we know the speed of the sub at the moment of collision then it is easy to see the future of it.

If it happened with full speed then the ship most likelly scrap.

You can't just cut off the front section and replace it. To connect a new section onto the body would require new welding, but with existing equipment already installed, it is next to impossible to do a good weld test. Without a weld test, no one will be comfortable diving that sub even to 50 m.

Prosecutor Commander Richard Federico alleged in court on Monday that text messages show Seaman Apprentice Ryan Sawyer Mays lied to family, friends and investigators about why he left Seal training and that he was angry about being reassigned to the Bonhomme Richard. They also alleged he used foul language with a superior days before the blaze.

How many ships have the US lost to arson/self sabotage? I can think of three in the past few years. They really need to start treating their sailors better.

It is not only arson.

Collision with underwater objects by submraines, overwater objects by ships, rusty ships, a single match destroying a 40 thousand tons, 2 billion warship.

These events showing deep issues, regards of organsiation, leadership, training, design and certification.

I mean, a 50 cents match could destroy a 40 k warship ?
Seriously ? What excuse could be presented for this case ? Where is a designer /supervisor of procurment to take responsibility ?

Two incidents one was an actual sailor. The Miami fire was a contractor.
Under water impact was an unmapped mountain. The USN has had some rusting but first more of the modern ships have smaller crews limiting the resources to paint. Next prolonged tours result in that anyway
