2. No Windows, Just Periscopes

Do sea creatures ever catch underwater admirals peeping? Not a chance: submarines don't have windows or portholes, instead, they use periscopes that rotate 360 degrees to keep an eye out on foes and obstacles, while using sonar to detect potential dangers lurking beneath the surface.

Who needs rose-colored glasses when you've got red submarine lighting? It's like turning your naval vessel into a floating love boat for those who simply can't resist the allure of dim romantic lighting: Submariners utilize red lights in the dark to maintain their night vision, ensuring they can effectively navigate their instrument panels and perform crucial tasks such as operating the periscope or standing watch duty.

4. Lingos of the Deep

Ahoy word lovers, prepare to dive deep into the linguistic ocean of submariners: they have their own unique lingo, like referring to deployments as "patrols" since WWII, and when a submarine doesn't make it home, it's deemed lost on an "eternal patrol" – that is, until they're found, sometimes even years later!

5. Whales: The Original Submarine

Believe it or not, submarines were not designed by a top-secret committee of undersea-dwelling whales, despite their uncanny resemblance to the graceful creatures: In reality, the streamlined and sleek bodies of whales merely inspired submarine engineers to craft a vessel that slices through water with minimal resistance. The aquatic trendsetters even lent a flipper in WWII by providing oil and meat for troops and assisting in naval communications - though it's unclear if they ever demanded royalties for their sub-aquatic inspiration.

7. Freezing-Feasts in Subs

Do submarines prefer their veggies chilled and their meats on ice? You bet your frozen-assets they do: Submarines feature two cold storage rooms—one at 40 degrees Fahrenheit for items like fruits, vegetables, and dairy products, and another at a frosty 15 degrees Fahrenheit for meats, poultry, and fish, making it essential to maintain proper temperature, humidity, and ventilation to prevent spoilage of their underwater buffet.
