Which was the Only submarine to sink another while both submerged?

Technically a Japanese Suicide sub could collide and explode into an American or other Allied sub, the resulting blast effects dooming both vessels- however, there is no evidence this actually happened during the Pacific war, the only two confirmed Kaiten (one-man suicide sub) kills were of a large tanker- and a destroyer escort- both surface vessels- though Chan:s motto applies to a ( sea-fight) more than other types of warfare, ah so the Motto of the Wise is- beware of surprises. Jap Suicide subs had an attack speed of 45 KNots submerged!

Which Navy was the first to fire a torpedo to a target from a submarine?
"Shooting" a torpedo is the proper term; the word "Fire" means only one thing aboard a submarine, and it has nothing to do with launching weapons.While the Nordenfelt-designed Turkish submarine Abdülhamid (1886) was the first submarine in the world to shoot a torpedo while submerged, it did not shoot at a designated target.The first submarine credited with shooting a torpedo underwater at a designated target (albeit a missed shot) was the Royal Hellenic Navy's (Greek) submarine Delfin, on December 22, 1912. The Delfin was shooting at the Ottoman light cruiser Mecidiye, at a range of 800m.
What are the benefits of building a nuclear submarine?
The main one is these submarines can effectively remain submerged (and thus hidden) all the time. They are only really limited by the amount of food they can carry for the crew.
Are submarines boats?
The term "Boat" used to reference Submarines goes back to the very earliest submarine designs. A "Boat" is a term used for a vessel launched from a Ship; Submarines were first designed during the days of wooden sailing vessels, and were launched like any other boat from the ship. Though the official U.S. Navy designation for a submarine ("SS", for Submersible Ship) goes back to the days when submarines were surface vessels (Ships) that had limited submerged operational capability, submariners have always referred to them as "Boats". Even today, 20 years after leaving the Submarine Force, I still get irritated when someone refers to a submarine as anything other than a Boat. Today's submarines are true submersibles - their operational capability is limited only by their crews (still need food, even if everything else is taken care of). Even modern Diesel Electric submarines, who in WW2 could only stay submerged for hours, can now remain submerged for weeks. The other major difference that changed the submarine was the switch to a hull design that favored submerged operations. The old WWI and WWII boats were much faster on the surface than submerged. In contrast, today's boats are much faster submerged than they are on the surface.
How does a diesel submarine recharge its batteries?
World War II submarines were powered by large electric motors. On the surface, the motors drew their power from diesel generators, not unlike how a diesel locomotive operates today. When submerged, the diesel engines could not be operated, and the motors drew their power from huge banks of electric batteries. After the batteries were drained of their power, the submarine would have to surface in order to run its diesel generators to provide propulsion and electric power to the submarine. During this period, the sub's batteries were recharged. Toward the end of World War II the submarine snorkel was invented, which gave a submarine the capability of running its diesel engines while submerged. The submarine was required to stay relatively close to the surface, but it was fully submerged with the exception of the snorkel mast. Nuclear powered submarines also have banks of electric batteries, but they are only used when the main propulsion plant and/or its steam-powered electric generators are disabled. When a nuclear-powered submarine's batteries are fully drained, they are recharged by the boat's diesel generator if its steam-powered electric generators are not available, or by the steam-powered electric generators when they becomes available. Just like a diesel-electric submarine, a nuclear-powered submarine must operate its diesel generator on or near the ocean's surface.
How is a submarine powered?
Modern submarines are powered by a nuclear reactor. Others are powered by diesel engines while they are on the surface and batteries while they are submerged. The older ones that were powered by diesel and batteries had their limitations. While they were on the surface running on diesel engines they left a trail of exhaust smoke which gave away their position. When they were submerged and running on batteries they could only last so long and then they had to come to the surface, run the diesel engines and recharge the batteries. The submarines that are run by nuclear power do not have to resurface for a very, very long time.

What is a difference between a boat and a submarine?
A submarine is a kind of boat. But regular boats only use the surface of the water while subs also can dive and travel below the surface.
Distance undersea that a submarine can travel today?
Today's Nuclear Powered Submarines' underwater cruising range is limited only by her crew. Without the need to resupply food, modern nukes could remain submerged indefinitely.During my own time as a Submariner, another boat in our Squadron, USS Seahorse (SSN-669) completed a full circumnavigation of the globe, posting 180 days submerged. For any submarine crew, that's a long time - even SpecOps boats like Parche were only gone and submerged for 4 months. My own personal submerged record is 72 days.Eventually in the future, the food barrier will be broken, but the psychological effects of working in confined spaces for months will not. After a couple of months, the air gets a bit stale, even if it is constantly replenished and purified. Due to the nature of submarine operations, snorkel operations aren't always a option to ventilate the boat with fresh air. Over time, stress and pressure begins to take its toll on even the most professional submariners. It is just a fact of human nature, but also a testament to those who can do it.
A sentence with submarine in it?
A submarine is only used under water.
What are some of the differences between a modern submarine and an older submarine?
Submarines of WWI and WWII vintage were not true submersibles like today's modern submarines. They were surface ships that had limited submergence capability for attack and evasion. Many battles were actually fought on the surface with both torpedo attacks and deck guns.Modern submarines are true submersibles in every sense of the word, even modern Diesel Electric boats. Nuclear Power has become the preferred method of power generation, and such engineering means a boat's submerged operations is limited only by crew supplies (food, etc.). DE's can remain submerged for weeks today, where in the past they could only remain submerged for hours.
Who invented the submerine during the renaissance?
The first underwater warship was developed by Leonardo da Vinci. da Vinci kept his plans secret because he didn't want to make war any more terrifying than it already was. In 1578 William Borne began drawing plans for a submarine. His submarine was never built. Borne's submarine worked by using extra tanks which could be filled so the submarine would submerge. The tanks would be emptied for the submarine to surface. In 1620 Cornelis Drebbel, a Dutch inventor, built a leather covered rowboat with oars. The oars came out through watertight seals. Twelve people could ride in the submarine. Drebbel was an engineer who worked for the British navy. Drebbel was the first to discuss the problem of air replenishment while the submarine submerged. Drebbel's submarine could only go down about fifteen feet. It could stay underwater for a couple of hours.
Does the fuel return line need to be submerged in fuel in the tank?
No, Only the supply line has to be submerged in fuel.
