While they’ve had some bad press of late, this content creator has made his own working submarine and revealed to his followers how he operates it.
The DIY project took him four years to complete.
However, when you know what’s at stake, it’s probably best to take your time on these things.
Honestly – it’s fascinating to see it in action.

The DIY submarine
Nicknamed ‘Lake Defender’, the self-made submarine is the work of content creator, @planesboatsandsubmarines.
It boasts three 55lb thrust motors, is steered with an analog joystick, and uses a scrubber system for oxygen.
Meanwhile, this $250,000 jet shark submarine can blast itself out of the water.

The video has amassed over 10.1 million views and how to dive underwater in it from his unique piloting POV.
How it dives
“The first thing we’re going to want to do is to get this power turned on, because we want this CO2 scrubber running,” he begins.
With the red lights on that allow for night vision in the deep, dark depths, he puts the countdown on the CO2 meter. and checks his oxygen levels.

“We’re going to run that right around 400 milliliters a minute,” he explains.
Next, he ensures the hatch is properly sealed with clamps before flooding the front and main ballast tanks.
These compartments hold water to provide stability, reduce stress, and improve propulsion.

“You can see the water coming up right there.”
After that, he floods the aft tank at the rear.
“Here comes the water,”
He explains that once water is level with the hatches, periscopes are turned off.
“We are underwater – and that’s how you do it, guys,” he concludes.
At the other end of the scale, this $1 billion mega-yacht comes with a hangar for aircraft and submarines.
Plus, this bubble submarine takes cruise passengers to the sea floor in first-class luxury.

All Supercar Blondie contributors undergo editorial review and fact-checking to ensure accuracy and authority in automotive journalism. After gaining her BA Hons in French and English at the University of Nottingham, Amelia embarked on a vocational diploma from the National Council for the Training of Journalists (NCTJ). This led to numerous opportunities, from interning at Vogue to being on the small team that launched Women’s Health magazine in the UK, which was named the PPA Consumer magazine of the year for three years running. As Health, Beauty and Fitness editor, Amelia personally received a Johnson & Johnson Award and was shortlisted for both PPA and BSME titles. Since then, Amelia has created content for numerous titles and brands, including the Telegraph, 111 Skin, Waitrose, Red magazine, Stylist, and Elle, as well as being Head of Content at Vitality and Editor in Chief at INLondon magazine. “My superpower is translating technical jargon about the mechanical workings of a supercar into a relatable story you’ll want to share with your friends after you’ve read it.” After joining the SB Media family as a senior journalist in September of 2023, Amelia’s role has evolved to see her heading up the SEO output of the editorial team. From researching the most ‘Google-able’ key terms to producing evergreen content - it’s been a time of hard work, growth, and success for the editorial team and the Supercar Blondie website. “I like to think of myself as a ‘method journalist’. In other words: I live and breathe whatever I am writing about. When writing about fitness, I trained as a personal trainer, and as a beauty editor, I completed an ‘expert’ in scent diploma with the Fragrance Foundation. “During my tenure at Supercar Blondie, however, I did something I never thought possible: I passed my driving test at the age of 36. One day I’d love to train as a mechanic to better understand what happens under the hood, too. “My sweet spot is providing readers with a ‘takeaway’ (read: something new they didn’t know before) after reading every one of my stories. While I don’t claim to be an expert in the automotive world, I know the experts and bodies in the field to rely on to provide our readers with an informative and thought-provoking story every time they visit the site.”
