Here’s a question that you don’t hearvery often; if a submarine and a whale collided, who would emerge victoriously?The answer to that is not definite because such an incident has not occurred sofar. However, back in 2005, the USS San Francisco did collide with a seamountat full speed. You can see the damage the collision caused in the picturebelow.

The $2.6 billion USS South Dakota (SSN 790), seen here in a photo illustration, is the newest, most-advanced addition to the US Navy's Virginia-class fleet of nuclear-powered, fast-attack submarines. Special Operations Ships and Submarines. Special Mission Ships and Submarines. Littoral Combat Ship - LCS. Ford Class Aircraft Carrier. USS Constitution. Deep Drone 8000. Submarines are incredible pieces of technology. Not so long ago, a naval force worked entirely above the water; with the addition of the submarine to the standard naval arsenal, the world below the surface became a battleground as well.
The USS San Francisco had a total of137 men aboard out of which 98 were injured, and one died. The USS SanFrancisco lost her forward ballast tanks but was still able to surface and thentravel for 360 nautical miles using her own power. The bow of the USS SanFrancisco was replaced using the bow of the recently decommissioned USSHonolulu and remained in active service up until 2016 when she underwentconversion to a training ship.
A whale would not have survived sucha collision since it would have been enough to inflict injuries that wouldprove fatal. On the other hand, if such a collision would cause fatalities onthe submarine; let’s hope we never have to find out. Rest assured, the whalesare good at getting out of the way of submarines, and that is why no suchcollision has taken place until now.
A submarine, also called a sub, is a watercraft capable of independent operation underwater. Submarines have multiple uses, such as tourism, undersea archaeology, facility inspection and maintenance, and marine science, salvage, and exploration. Military uses of submarines include attacking enemy ships or submarines, protecting aircraft carriers and other ships, acting as a nuclear strike force, blockade running, and more.
Submarines were first widely used during World War I. Many navies now have a fleet of submarines, both large and small, primarily using them as a deterrent in territorial waters. A standard fleet is typically about five or more boats.
In the United States, there are three types of U.S. Navy submarines: ballistic missile submarines, attack submarines, and cruise missile submarines. The U.S. had the world’s first submersible with a documented record of use in combat called the Turtle. The Turtle was builtin 1775 and was used to attach explosive charges to ships in a harbor. Specifically, it was used against the Royal Navy vessels in the American Revolutionary War.
The modern submarine design was made around the 19th century. Most large submarines have a cylindrical body with hemispherical (or conical) ends. Submarines also typically have a vertical structure that houses sensing devices, periscopes, and communications devices. This vertical structure is called a “sail” in the United States and a “fin” in Europe. Additionally, there is a propeller at the rear and several hydrodynamic control fins.

In World War II, submarines proved to be very effective and very deadly tools. Germany used submarines during the war in the Battle of the Atlantic, cutting off Britain’s supply route by sinking merchant ships. The Imperial Japanese Navy operated the most diverse fleet of submarines in the war of all sizes, including midget submarines, medium-range submarines, and long-range fleet submarines. The Japanese also had the fastest submarines, ones that could carry multiple aircraft and those equipped with the most advanced torpedoes.
Number of Submarines by Country

Global Fire Power collected the most recent data on each nation’s number of naval submarines.
Submarines In Ww1
Landlocked countries typically do not have a standing navy and, therefore, do not have submarines. Those countries were not included in GFP’s rankings. The rankings do not distinguish between the types of submarines, size, age, or construction quality that each nation has.
