In WWII, US Gato class subs were about 311 feet long. A Fletcher Class destroyer was about 376 feet long. US cruisers were about 500 to 600 feet long. The IJN I-400 class sub was 400 feet long, the largest sub in WWII.
Under water bombs are called naval mines. Under water bombs are used to destroy surface ships or submarines.

Submarines have a rudder like most surface ships.
Normal ships are designed to move on the surface of the water. Submarines are designed to be able to submerge and travel under the water's surface, as well as on the surface. When normal ships go down, they stay down. Submarines are able to come back up after they go down. All American submarines are nuclear powered. With the exception of Aircraft carriers, surface ships are powered conventially.
Submarines are designed with enough ballast and control systems to allow them to submerge and surface as needed.Surface ships are designed only with enough ballast and control systems to keep them on the surface. While they can sink just as well as submarines can, their ability to re-surface without a salvage operation is non-existent.
Submarines are commonly referred to as "boats" due to naval tradition, which dates back to the early days of maritime language. Historically, smaller vessels were called boats, while larger ships were referred to as ships. This terminology has persisted, and even though submarines are technically large underwater vessels, they retain the "boat" designation as a nod to their origins and the conventions of naval terminology.
John Holland built submarines to provide a new and effective means of naval warfare and to address the limitations of surface ships. His designs focused on stealth and the element of surprise, allowing submarines to operate undetected and strike from beneath the water. Holland's innovations laid the foundation for modern submarine technology, as he aimed to enhance naval capabilities and protect maritime interests. His work ultimately led to the development of the first successful military submarines.
Submarines can launch a variety of munitions, primarily torpedoes and missiles. Torpedoes are underwater weapons designed to target ships and submarines, while missiles, such as cruise missiles, can be used for land strikes or targeting other ships. Submarines may also deploy naval mines as a means of area denial or to disrupt enemy naval operations. Each type of weapon is designed to be launched from a specific system onboard the submarine.
Torpedoman's mate was a United States Navy occupational rating for an enlisted naval serviceman whose main duties are the handling, preparation, and maintenance of torpedoes and other underwater ordnance, that are launched from submarines, surface ships and aircraft. This position was disestablished on October 1, 2007 and torpedo men of surface ships were given the gunner's mate rating and those on submarines were given the machinist's mate rating.
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.
The number of decommissioned ships in a navy can vary widely depending on the country and its naval policies. For example, the U.S. Navy has several hundred decommissioned vessels, including aircraft carriers, submarines, and surface ships, often stored in the Naval Inactive Ship Maintenance Facility or sold for scrap. For specific numbers, it's best to consult the latest reports or official statements from the respective navy.
Reactors power submarines and many surface ships. Nuclear weapons.
