On April 10, 1963, I was in the 5th grade.PERMIT. a friend classmate was doing a cross-sectional view of the USS George Washington ballistic missile submarine on the bulletin board in the back of our classroom. Both of our dads worked on submarines in Groton, CT. That morning, on April 10th, my friend came to school, and he told me that the USS Thresher SSN-593 was overdue at returning to Port. I was saddened by her loss. 8 years later, I was assigned to the USS PERMIT SSN-594. My interest in submarines began in 1961 after seeing the movie Voyage To The Bottom Of The Sea. I'm proud to have served on the USS Permit SSN-594.

[@jamescannon7267]

I worked on SSN 575 and SSN 571 Nautilus as a pipe fitter at Mare Island Naval Shipyard, Vallejo California where it was decommissioned. Ocean Engineering used this boat for special use and that’s where I worked. I had a Top Secret clearance as all did working on this platform so I can not say what we did and even I din’t know anything about it’s mission. Modular construction did not exist so we constructed every piece of pipe by hand as did all the other trades. We did excellent construction at every step and everything we did was inspected. It was a great time in my career. Today the Ballistic Nuclear Submarine is the most powerful weapons platform on earth, I call it, The Doomsday Machine.

The Seawolf Class needs to go on a war time crash build program of no less that 15 more attack subs in 6-7 years. Looks like they will be needed sooner rather than later in Asia and they give capabilities other attack subs do not have.😊

[@MrGsteele]

The Seawolf Class is history; DoD has moved on from Seawolf to the less expensive Virginia Class submarine. We built 3 Seawolves, and have since built 21 Virginia Class boats. Less capable, but also much less expensive - and where submarines are concerned, more is better - much better. It's about coverage, not capability; these are attack subs, whose job it is - predominantly - to take out enemy shipping with Mk 48 torpedoes, and land-based military facilities with Tomahawk cruise missiles. They have other roles, but that's the primary reason we build them. Between the 21 Virginias, the 40 688 class subs - 30 of which have Vertical Launch Systems for Tomahawks, and the 3 SSGNs - converted Ohio-class ballistic missile subs now equipped for an attack class role - we are on a major treadmill building the foundation of our anti-Russian fleet, and anti-Chinese fleet, control apparatus. With the buffoons currently running Washington, we may soon need them.

[@chadjackson5113]

My father worked at EB for 35 years, he was a project manager on the weapons systems for the boomers and fast attacks. Very interesting in the multitude of the various attack and insertion characteristics of subs. Correct EB secured a huge contract to build the VA class and certain aspects were carried over from the Seawolf class. As you noted the Seawolf was very expensive to build. He used to go out on the sea trials for the subs before they fully handed them over to the Navy. Some of the stories he has told me are riveting. Lot's of stuff he could never share because of the classified nature.

[@kenashworth7672]

I was a nuclear engineer in the US Navy. I truly think Hyman G. Rickover may have been one of the greatest engineers of the 20th century, if not the greatest. Yeah, I'm an ex-nuke Rickover fanboy, and unashamed. My hero was a Jewish mad scientist Admiral who somehow managed to convince Congress that it was safe to operate a nuclear reactor underwater, and then delivered on it. I am jealous that they now have all the manuals available in digital format. I know it's not a good look. But there were freeking literally tons of manuals on everything everywhere. You could stumble around in engineering, touch something and chances are there was either a manual for that if you didn't lose a finger, or there may have been a manual even if you did lose a finger. But my point isn't fingers, it is the manuals this metaphorical finger fingered - that is "fingered" in the context of pointing at things with manuals - with the "manuals" being the point. I'm trying to so there were so many manuals. It's so cool that's now not on big physical paper binders. While having a lot of paper, also had other materials, because binders require other materials (including metal, which to be clear, is not paper) to properly function as minders. Although I do not recall there was a manual on the binders - they just went wild and figured nuclear engineers would derive the engineering that goes into the construction of a binder and intuitively grasp how to operate the binder - even if the binder comprised of more materials than paper. But that also is not my point, my point is the mass. They took up space and were heavy. I like manuals - I just like manuals more when they are digital so weigh nothing - much less than the something it was - which was a lot.

[@paulmichals]

@kenashworth7672 I am also an ex-nuc. I was an RO on a SSN 637 class out of Pearl from 76-79. I remember when we would get back to port having to use some big mid 1970's copy machine at some office on shore, using ream after ream of paper, to make x-number of copies of the latest set of revisions of the nuc manuals. Then go back to the boat and spend hours updating all the binders back aft. I am also a Rickover admirer and highly recommend Polmar & Allen's book: "Rickover". The joke back when I was in was that the "G" of his middle names was for God. I spent much of my early 20s: underway, underwater, on watch.

[@CraigRasmussen1]

I was a nuc officer on USS Flasher (SSN 613) from 1966 to 1971. Understand your point here. If all systems failed….we could probably sink somebody by hitting them with RPM manuals. Each one of the things weighed `5-6 lbs.

[@omg2569]

Seawolf-class nuclear submarines like the USS Connecticut use passive sonar to identify and locate targets. Passive sonar is highly covert and has long detection range and it is the preferred way for submarine underwater detection in peace-time operations and daily sailing. When it comes to offensive maneuvers or navigating in environments with complex bottom topography, submarines would change to positive sonar for detection. But some recent analysis suggest that submarines would also use passive sonar to cover their tracks sometimes,

[@hudsonslim3169]

So many people commenting here seem to find documentaries like this, which showcase state-of-the-art technology at the time, hysterically funny. Perhaps they lack the awareness to see that today's state-of-the-art technology may seem just as 'laughable' 30 years from now. They also seem to forget that these systems don't stand still but are constantly being upgraded. Today's technology didn't spring into being out of nowhere. It's the result of decades, even hundreds of years, of technological innovation and evolution.

[@jsteins]

0:11 Can you imagine being in the sub crew during a rapid surfacing where the bow launches over 60ft above the water, and then falls the height of a 8 story building back below the waves !?! While this sort of looks like a whale playing on the surface, you have to realize the scale of that sub about 40ft tall (nearly 15m without conning tower) and the nose went way farther into the air, then splashed down to submerged level again. HOLD ON !! That's taking every person and machine on a wild roller coaster ride. Tie EvErYtHiNg down (especially the torpedos)... tell the kitchen NoT to be cooking/serving anything at the time, and hope nobody was trying to use the bathroom. How does a nuclear reactor like being tossed into the air, then dropped five stories or more while still generating about 80% of its rated power ?? ( I guess they build 'em Navy tough )

Unfortunately these were designed using early CAD/CAM. Many parts were over designed and almost impossible to manufacture. With each unit becoming almost a prototype.

[@rdallas81]

[@thepandeslar8062]

What makes you think military-industrial complex engineering facilities stopped designing when the prototype part was made? I've seen instances where fasteners went through 25 revisions after release. Never mind electronics going from SMT (surface mount technology) PC boards to stand-alone integrated devices. Check out how many transistors you can get on the head of a pin. Ever hear of Moore's Law? New advances in AI computer design are making it obsolete. And nowadays, virtually no discrete part is impossible to manufacture. The biggest drawback is the cost of desirable material in quantity (think graphene in large sheets). Another drawback is the current level of available technology, and the reluctance to invest in exploiting new avenues of thought. AutoCAD is a great program, but it isn't the program of choice for high-tech design.
