The Trieste was that famous submarine. It is actually considered a bathyscaphe, but the term submarine could be applied. It dove to the deepest undersea point in the world, the Challenger Deep in the Mariana Trench, where the water depth is nearly 36,000 feet. A link is provided to the Wikipedia article on this revolutionary undersea vehicle.
The depth charge was developed by the British Royal Navy during World War I, with significant contributions from various naval designers. Its early design was influenced by the work of Admiral Sir Reginald Aylmer Ranfurly Plunkett-Ernle-Erle-Drax and others who sought to counter the threat posed by submarines. The first effective depth charge was introduced in 1916, marking a pivotal advancement in anti-submarine warfare.
The famous artist who painted "The Last Supper" is Leonardo da Vinci. This iconic mural, created between 1495 and 1498, depicts the moment Jesus announces that one of his disciples will betray him. It is located in the Convent of Santa Maria delle Grazie in Milan, Italy, and is renowned for its innovative composition and emotional depth.
The Naval Warfare Designator for Submariners is a pair of Gold (Officer) or Silver (Enlisted) dolphins, each one abreast of the bow of a submarine. There are many variants on the design, though most of us have always preferred the older, traditional design (see my Supervisor page). Some Officer's dolphins also include their specialty within the design, where the bow of a submarine is replaced by the specialty insignia, with the dolphins abreast of it. For example, the Engineer will have an encircled propeller with dolphins on either side, Supply Officer (Chop) a Supply Corps insignia, and a Submarine Doctor an oak leaf with a blue jewel thingie. Newer variants also show a modern teardrop/cigar shaped hull to signify more modern boats, but I always preferred the old style with the Fleet Boat bow design. The dolphins are used in the insignia because dolphins historically are considered friends of sailors, and submarines especially. Dolphins are constant companions riding a submarine's bow wave on the surface, and are usually around a boat at periscope depth as well.

Early in the morning on December 7, 1941, the "U.S.S. Ward,", a navy destroyer stationed at Pearl Harbor, spotted a submarine near the harbor-entrance. As an unidentified vessel in restricted waters (and with war imminent), the sub was viewed as hostile and was attacked: it was quickly sunk through a combination of gunfire and depth charges launched by the "Ward."
The new depth of the submarine is at -43.75 meters.
Width
The submarine was at a depth of 3,000 feet.
depth
The depth of a submarine under the sea means how many feet below the surface of the sea it is.
Depth. To ascend is to go up, and to descend is go down. We measure the height of things above the ground and the depth of things below the ground.

Depth perception.
When a submarine is traveling at a constant depth, the primary forces acting on it are buoyancy, gravity, drag (or hydrodynamic resistance), and thrust. The buoyant force, which acts upward, is equal to the weight of the water displaced by the submarine, while gravity pulls the submarine downward. For the submarine to maintain a constant depth, these forces must be balanced, meaning the buoyant force equals the gravitational force. Additionally, the thrust generated by the submarine's engines must counteract the drag force to maintain a steady speed.
It varies by the type of submarine. United States, Russia, United Kingdom, China, France, and India are examples of nations who have or are assumed to have nuclear submarine capabilities.For security purposes, governments don't give out full specifications on their weapons of war, especially on something as big, expensive, and instrumental as a submarine. The true depth information is classified, probably above "Top Secret". For the general US submarine fleet, the "official" answer is typically around 600 feet. (According to one Navy instructor it was changed from 400 feet when a documentary was aired accidentally showing footage of the depth meter at a depth of around that depth.)Any Navy in the world who operates a nuclear submarine is going to publish a low ballpark figure in the name of national security and secrecy. If everyone knew the exact depth a submarine could submerse to, it'd be easier to kill them. Wikipedia says a Soviet/Russian class Alpha submarine may have successfully operated at a depth of 4,300 feet. But rest assured whatever the published depth of submarine is, it many times greater than that.
Submarines are equipped with fore planes to enhance their maneuverability and control, especially during submerged operations. These horizontal stabilizers help manage the submarine's pitch, allowing it to ascend or descend more efficiently and maintain a steady depth. Additionally, fore planes improve the submarine's hydrodynamic performance, contributing to better speed and stability while navigating underwater.
