Note: The US Navy put no restrictions on me about what I should say or how I should present what I learned on this trip. Other than making sure my footage was cleared for Operational Security, I am free to say whatever I want about this experience.
Another note: The Navy did not ask me to provide a link to their website (or do anything for that matter), but I’m going to provide a link because I want smart people to become submariners. The US Navy continues to provide stability and security in ways no other organization on earth does. If you are interested to find out how you can join the Navy you can visit the website here:
There are tons of interesting career opportunities out there that I never knew about:
The US Navy has several options such as engineer, pilot, submariner, logistics, accountant, medical doctor, and even Public Affairs specialist. I continue to be impressed by people that I meed who spent time in the Navy. I worked with various people during the course of filming this video and they were all top notch.
Here's a video about loading and firing a harpoon missile from the USS Olympia (I filmed the impact):

    When I boarded the USS Toledo I did not know I was going to be given the opportunity to crawl down a torpedo tube. Honestly I was thinking I would have a conversation with someone about the periscope or something but it did not occur to me that when you are under the ice you cannot use the periscope. When they asked me if I wanted to see a torpedo tube I didn’t realized I had no clue how they worked. Most people overlook this seemingly simple system, but when you take a moment and analyze it you will realize it is quite complicated. I hope this is the level of detail you were hoping for in the submarine series, because this is what gets me excited. I haven’t decided which video is next but I’ll tell you this, I did not know one of the methods they use on board to make oxygen. Anyways, thank you for watching the series and please consider subscribing if you feel like this is worthy of your time. I don’t know if you’re the type of person that likes to share videos with other people, but I would appreciate it if you could pass the submarine series on to a friend or two. As always, I would like to express my gratitude to people who support Smarter every day on Patreon at . I am thankful for the support, and the next video has a special surprise for you, the Patrons.

    I worked at the Electric Boat nuclear sub facility in Quonset Point, Rhode Island and worked on the sister 688 Fast Attack Subssubs when the Toledo was being built in Newport News. I remember installing the electrical and electronic components in the topedo room. I never got to see the finished sub because we did about 90% of the work and all the finish work was done at Electric Boat Groton, CT. Thanks for a really cool trip down memory lane! Now I have to watch the rest of your videos!

    I got the chance to crawl down a torpedo tube on my first boat (USS John C. Calhoun, SSBN-630B) when we were at Test Depth. It's a common tradition on Navy Subs and is quite a surreal feeling as you're crawling down the tube with nothing but a steel door between you and crushing sea pressure. Definitely not for those who have even the slightest smidge of clausterphobia.

    My 'initiation' on my first boat was to dive a torpedo tube (as a Sonar Tech, I was leery of this but knew it was a right of passage). No headlamp, no flashlight...just dive the tube with a greenie and clean. Get to the outer door and boom, the breach door closed. Pitch black. Rolled over on my back and snoozed til the TM's let me out! Guess I didn't freak out like they were expecting!

    Nightmare fuel: you've crawled inside the torpedo tube to check it out. Suddenly you hear the breach door close and lock. Your breath is rapidly siphoned from your lungs as the air pressure inside the tube plummets, and ice-cold seawater comes flooding in.
