One weapon that was used by submarines were torpedoes. Torpedoes were like big rockets, but they didn't explode. They were like huge wrecking balls that were fired a huge velocity, and were normally used to wreck ships.
Back then, in the cold war, the Americans stored four torpedoes in a submarine now called the Growler, which you can see at the intrepid sea air and space museum today. However, back then, if they wanted to fire these torpedoes, they would have to surface, wheel the torpedo out, load it, and fire it. This process would take about fifteen minutes.
Luckily, today, scientists have found a way to waterproof these torpedoes.
Ans 2 - Submarines have used torpedoes from underwater since WW1 . Many subs in WW1 and WW2 also had deck guns, sometimes a naval cannon for use against ships and often heavy machine guns as protection from aircraft.
Modern submarines commonly carry cruise missiles or ICBM's as well as torpedoes. Torpedoes have evolved from the simple ones in WW2 that had a range of about 3 miles to a whole variety of torpedoes that can go for up to 40 miles and loiter or speed as required. Most modern torpedoes are shot from 21 inch tubes, but there are 16" torpedoes used by many European navies for shallow water.
Germany must surrender its submarines and weapons
submarines were used in WW1 and the weapons used were torpedos and a deck gun.
Weapons launched (fired) from submarines include torpedoes, ballistic missiles, or cruise missiles. These are the primary weapons, and a few other options exist.
Torpedoes were the main weapon. The submarines also had a naval gun that they would use on unarmed ships and many had machine gun mounts as well.
They had no weapons.

Since its free-fall nuclear weapons arsenal was decomissioned in 1998, the United Kingdom's only means of nuclear weapons delivery is via submarines and SLBMs.
Most fast-attack submarines rely on several anti-ship / anti-submarine weapons, but the most common U.S. weapons are: Mk. 48 ADCAP Torpedo (surface ship and submarine) Tomahawk Anti-Ship Missile (TASM) (surface ship) Harpoon Anti-Ship Missile (surface ship) Mk. 60 CAPTOR Mines (submarines) U.S. submarines also carry the land-attack version (conventional, multi-purpose or nuclear) versions of the Tomahawk (TLAM, TLAM-N).
The existence of submarines forced other countries to develop anti-submarine weapons and detection systems.
Because a navy at war has to use it's most effective weapons
He directed the use of every weapon that was known at that time with the exception of chemical weapons. Those included small arms, artillery, tanks, submarines, battleships, bomber aircraft and guided missiles. Germany did not have nuclear weapons at that time. There is speculation that Hitler did not order the use of chemical weapons due to his experience in WW 1 as a solder- he was injured in a gas attack.
