In the world of crosswords and scanwords, there are often puzzles that require not only knowledge but also logical thinking. One of these popular questions is to find the four-letter word for the person who described the first submarine. The answer lies in the history of technology and literature, namely, the name. bacon (Francis Bacon) It was this English philosopher and scientist who, in his book New Atlantis, gave a detailed description of a submarine long before the real prototypes came along.
However, if you look at the question from a technical point of view, "description" can be interpreted as the creation of a first drawing or project. drabbel (Cornelius Drebbel), who built the first real-life model, but the 4-letter crossword puzzle most often requires the surname. baconIt fits perfectly into the grid and corresponds to the historical fact of the literary description.
In this article, we'll not only answer the puzzle, but also dive into the fascinating world of early submarine shipbuilding, where engineers' thoughts evolved, what materials were used and how they evolved. submarine From wooden boxes to steel giants.
Historical context: who and when described the submarine
The history of scuba diving goes back to ancient times, but the first documented description of the concept of a submarine that can be considered science fiction of the time is attributed to Francis Bacon. In 1624, after his death, the novel New Atlantis was published, where he described a device that can dive underwater and swim there for a long time. description It was the foundation for many subsequent inventors.
But the theoretical science quickly changed to practice, and in 1620, the Dutch engineer Cornelius Drebbel showed King James I his invention on the Thames. submarine It was a wooden boat, leather-covered and oil-sealed, rowing in rowers, and air was fed through tubes, and it was the first step from dream to reality, although full-fledged combat units were still a long way off.
Interestingly, many of their contemporaries viewed such experiments with apprehension as interference in divine affairs, but the military potential of stealthy underwater travel was evident to the rulers of the time. Engineers They sought ways to improve the autonomy and depth of immersion, which led to the emergence of many patents in the seventeenth and eighteenth centuries.
Technical specifications of early prototypes
The first submarines were little like modern nuclear cruisers, they were bulky, slow and extremely dangerous to the crew, the main engine was human muscles, rowers rotated oars, bred through sealed oars. Hermetization It was the main problem that was solved with the help of resined sails and skin.
The air supply system was also primitive, and early models, like Drebbel's boat, used leather bags that opened and closed to supply air, or long pipes that surfaced. Later, in late eighteenth-century designs, they began to use chemical methods to regenerate air using air regeneration using the use of air regenerating chemicals. potassium It's for carbon dioxide absorption.
Here are the main specifications that distinguished early prototypes from later models:
- ⚓ Shell material: wood, upholstered with leather or lead leaves, making them vulnerable even in small collisions.
- 🌊 Depth of immersion: It rarely exceeded 3-5 meters, as the water pressure quickly deformed the fragile body.
- ⏱️ Time of autonomy: The crew was between 30 minutes and 2-3 hours, after which they risked suffocation.
- 🚣 Driver: exclusively propellers or paddles, rotated manually, which required huge physical costs.
When studying the history of submarines, pay attention to the evolution of materials: the transition from wood to metal became possible only with the development of the steel industry in the second half of the XIX century.
The evolution of underwater engines: from muscles to electricity
Long time. submarine Curiosities were the curiosities of fairs and royal fun, the turning point was the invention of internal combustion engines and electric motors, steam engines required oxygen to burn, making them impossible to use underwater without special shafts raised above the water.
The real revolution was the advent of electric batteries, which allowed for the creation of fully autonomous submarines that could hide from the eyes of the enemy. Otto's engine. And these were used to charge the batteries on the surface, and the boat went under the water to a quiet electric course, and this separation into two modes became the standard for decades.
A special place in history is the Turtle, a single-seat submarine from the American Revolutionary War, which was propelled by a foot-driven vehicle and was designed to attach mines to the bottoms of enemy boats. combat The submarine in history.

Comparative Table: First Projects vs. Reality
To better understand the gap between the theoretical descriptions and the first implemented models, it is worth turning to comparative analysis, often describing ideal conditions that were difficult for engineers to achieve in practice.
| Parameter | Project by F. Bacon (Literary) | Boat of K. Drebbel (1620) | Bushnell's Turtle (1776) |
|---|---|---|---|
| Crew | Not specified (large was assumed) | 12 rowers + steering | 1 person |
| Driver | Not detailed. | 6 pairs of bols | Foot screw |
| Depth. | Not limited (theoretically) | 4-5 meters | Up to 7 meters. |
| Purpose | Research/Transport | Demonstration | Military attack |
As you can see from the table, it took centuries to move from the literary description to the real device, and if Bacon was talking about possibilities in general, Drebbel and Bushnell were fighting for every meter of depth and minute of air. Technological progress This was a leap in the direction of industry, depending on related industries.
Key figures in the history of scuba diving
You can't talk about the first submarines without mentioning the people whose names are forever inscribed in history. David Bushnell.He invented the Turtle, and he proved that a submarine could be an effective weapon, not just a toy.
Another important name is Robert Fulton, better known as the inventor of the first steamship, but he built the Nautilus, a copper submarine with a sail to navigate the surface, and his project was rejected by Napoleon, who considered submarine warfare "not fair," but the idea was already in the air.
In Russia, the pioneer of scuba diving is considered Efim NikonovIn 1718, Peter I was given the project of "submarine fire" (submarine), although his project was not completed during the life of the king, it was an important stage in the development of domestic shipbuilding.
⚠️ Attention: Don't confuse literary descriptions with technical drawings. Bacon described the idea, and Drebbel created a working mechanism. In crossword puzzles, this distinction often becomes the key to the clue.
Why did Napoleon abandon the submarine?
Napoleon Bonaparte considered the use of submarines to be a “pirate” and “unworthy of a great nation” way of warfare, preferring the traditional battle fleet.
The Contemporary Significance of the First Discoveries
Today, when nuclear-powered submarines plow the depths of the oceans and carry nuclear weapons, it's hard to believe that it all started with wooden boxes and leather bags, but the principles laid down by the first inventors are still relevant today. TightnessBalancing buoyancy and autonomy are the three whales on which the modern submarine is based.
Learning the history of the first submarines is important not only for solving crossword puzzles, but also for understanding engineering. Engineers of the past did not have computers, strong alloys and electronics, but their ingenuity allowed them to create working mechanisms. Innovation The result of that time was pure enthusiasm and risk.
For water-engineers and marine history enthusiasts, knowing these facts helps to better appreciate modern technology. When you see a modern PVC boat or boat, remember the journey humanity has taken to learn to feel confident on and under water.
The phrase “described the first submarine” in 4 letters is most often a reference to Francis Bacon, whose literary work anticipated technical reality.
⚠️ Attention: When building models or studying history, always check sources. Many of the "facts" about the first submarines are myths generated by documentary evidence from the time.
Frequently Asked Questions (FAQ)
Which 4-letter word should be included in the crossword puzzle?
The most likely answer is BAKON (Francis Bacon) because he was the one who described the submarine in New Atlantis. DREB
When was the first real submarine built?
The first real submarine is considered to be the boat Cornelius Drebbel, launched into the water. 1620 It could go down a few meters and move underwater.
What were the first submarines made of?
The main material was treeThe sealing used leather, tar-sea, and sometimes lead sheets, and the metal casings came much later.
Who was the first to use a submarine in the war?
The first combat use was during the American Revolutionary War in 1776, when the American submarine Turtle tried to attack the British flagship, but the mine did not gain a foothold.
⚠️ Attention: If you're building a model submarine yourself, be aware of safety precautions when working with adhesives and electronics. Do not test homemade devices in deep water unattended.
