no because torpedos are self propelled, people are too but the are to slow to be "launched" from a torpedo tube.

Torpedo tubes facing the rear (aft) of the vessel.

Original Answer: A burst of compressed air forces the torpedo out of the tube. Then the torpedo's motor starts up and drives it in search of the enemy. Improved Answer: While the above isn't wrong it's not accurate either. Air is used in most delivery systems, but just releasing compressed air behind the torpedo inside the tube is inefficient and very noisy. Most submarines utilize a system of two cylinders connected by a common tail rod. Air is released into one cylinder sending the plunger and adjoining rod rapidly to the other end of the cylinder. This force is transferred through the common tail rod to the water cylinder which in preparing the weapon battery is opened to sea on one side and to the rear of the torpedo tube on the other. When the water cylinder's plunger moves with the air cylinder it forces water into the tube ejecting the torpedo. This is a more efficient use of energy and can be done very covertly by experienced crews who take good care of their submarine. Since a submarine's key defensive is its stealth, this is a critical aspect of submarine warfare.

A warshot torpedo is a fully armed and operational torpedo that is ready to be fired at an enemy target during wartime. It is designed to cause maximum damage and destruction upon impact. Warshot torpedoes play a crucial role in naval warfare, particularly in submarine operations.

About six feet.

Torpedoes aren't like bullets; they have little engines that propel them to their targets. No one wants the engine to start while the torpedo is still in the boat, so the torpedo is shot about six feet out of the tube with a huge burst of compressed air. After it's free of the boat, the engine starts and propels the torpedo as far as it will swim...the Navy's Mk.48 torpedo will go 20 to 30 miles depending on how fast they set it to go.
