John Philip Holland, an Irish-born engineer and inventor, was a visionary whose daring spirit and ingenuity helped shape the future of submarine warfare. His journey into underwater navigation began with a bold and risky experiment: the construction and personal testing of a one-man submarine in 1878.
At a time when the concept of a practical, fully submersible vessel was met with skepticism, Holland refused to be discouraged. Instead, he designed and built a 14-foot-long experimental submarine, known as Holland I, which was powered by a simple hand-cranked propulsion system and equipped with ballast tanks for controlled submersion.

The Dreadnought class is the next generation of ballistic missile submarines (SSBNs) being developed for the Royal Navy, designed to replace the aging Vanguard-class submarines that currently carry the UK’s Trident nuclear deterrent. These nuclear-powered submarines will be among the most advanced in the world, capable of remaining submerged for extended periods thanks to their nuclear reactor propulsion. Measuring approximately 153 meters in length, they will be slightly larger than their predecessors and feature significant technological advancements.

The Petrie Ironman diving suit, invented by Captain Enos B. Petrie of Brooklyn, was a revolutionary advancement in deep-sea exploration during the early 20th century between 1902 and 1907. It marked a significant breakthrough in diving technology, allowing divers to operate at unprecedented depths with greater safety and efficiency. The suit, composed of aluminum alloy and weighing 450 pounds, was designed to maintain surface-level pressure, enabling the diver to avoid decompression sickness, also known as “the bends.” This innovation was a response to the limitations of traditional rubber diving suits with metal helmets, which were only effective at shallower depths and often left divers exhausted.

Çektirme is the kind of boat that effortlessly steals the spotlight. Long, sleek, and designed for both speed and style, it has graced the waters of the Aegean and Mediterranean for centuries. This Turkish sailboat, once a staple of Ottoman maritime life, is more than just a vessel—it’s a symbol of seafaring elegance and craftsmanship.
Typically spanning between 15 to 30 meters in length, the çektirme was built with speed in mind. Its narrow hull, usually around 4 to 5 meters wide, allowed it to slice through the water with minimal resistance, making it perfect for the breezy, calm waters of the Mediterranean. What really set the çektirme apart, though, was its lateen sail configuration—those iconic triangular sails mounted on tall, elegant masts. This sail setup wasn’t just for show. Lateen sails allowed the boat to tack against the wind efficiently, giving it a leg up when maneuvering through the often gusty Aegean Sea.
