How much does submarines weigh?
There have been many sizes of submarine from the tiny British X-boats weighing about 6 tons to huge 'boomers' weighing over 8,000 tons
Was the submarine effective in World War I?
Yes, A German U-Boat sunk The Lusitania, eventually causing The United States to join the war, I'd say that's a huge impact.Undoubtedly. The submarine came of age in World War 1, but its success was less than it could have been because admirals preferred to fight with massive fleets of surface ships. Navies had submarines in earlier wars (late 1800's, early 1900's), but they were held out of action. In World War 1, the submarine proved itself a warship that could no longer be ignored. As evidence that submarines were not taken seriously before the war, no anti-submarine weapons were invented until after submarines began sinking enemy ships.The most famous submarines of WWI were the German U-Boats (U standing for Untersee, the German word for underwater)
Are submarines large are small?
they can be in different sizes such as being long or short or huge and small
How to use the word armies' in a sentence?
The armies' tanks were huge.
How do submarines recharge their 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.
What is the ballast on a boat?
Weight used to keep the boat stable in the water. Old seagoing vessels, such as pirate ships use to have ballast stone which was kept in the bottom of the boat down the middle(keel) to keep the boat sitting properly in the water. Modern submarines use saltwater in their ballast tanks(big huge tanks located inside the hull) to enable them to sink and remain submerged
What strategy did convoys use to help the allies combat German submarines warfare?
They had difficulty in combating merchant convoys to and from their overseas allied nations, as German submarines were a huge threat. Their main tactic was the use of depth-charges, which even if they did not hit the submarine directly, created an overpressure effect which could rupture a sub's hull. They also relied heavily upon heavily-armed naval escorts which had the capacity to fire ship-borne torpedoes, as well as upon their own submarines to track and hunt down German and Japanese ones.
Why the tanks broke the stalemate?
Tanks are huge killing machines. They had not been seen/used before WW1 and were both deadly and psychologically terrifying.

Why were nuclear submarines considered a big technological advance during the 1950's?
Not until the advent of Nuclear Power and the vision of Naval Engineer Hyman G. Rickover (Admiral Rickover, "Father of the Nuclear Navy"), did submarines become true submersibles.Until that time, submarines were essentially designed as surface vessels that had a limited submerged operational capability, and were designed to run faster on the surface than underwater. Captured U-boats after WWII showed how far the Germans had advanced the art of submarine hull design and technology; while many of these innovations found their way into modern submarines, it was Rickover who realized that harnessing a nuclear reactor in a small design used to power submarines (and later ships) would give submarine warfare a significant technological boost. Unlike diesel-electric technology, nuclear power offers the advantage of huge power generation, which means better equipment (sensors, weapons, navigation, huge fresh water / air generating capacity, etc.), underwater speed (a major departure from previous designs) and virtually unlimited cruising range.With his successful pressurized-water reactor design (still in use today) installed on the United States' (and the world's) first nuclear powered submarine, USS Nautilus (SSN-571), nuclear power changed submarine technology and warfare from the limited role that it had in previous conflicts to the multiple mission threat it is today.The application of Nuclear Power "sealed the deal" and allowed for the development of the highly capable and extremely complex modern submarine. Modern boats are only limited by her crew requirements, can dive deeper and move much faster underwater than on the surface, and have many different tactical capabilities. They are true submarines by every definition.
Where can I find plastic tanks online?
It depends on what kind of tanks you're looking for. There's a a site called the tank depot online that has a huge variety of plastic tanks that may be useful to you. The number is 1-866-926-5603
When were submarines used?
There were subs in the 19th century, but they were really a part of naval warfare from World War One to the end of the Cold War. If large scale war breaks out in the near future, expect submarines to be a huge factor on the ocean front.
