United States Navy

The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. The U.S. Navy is the largest, most capable navy in the world, with the highest combined battle fleet tonnage. The U.S. Navy has the world's largest aircraft carrier fleet, with ten in service, two in the reserve fleet, and three new carriers under construction. The service has 328,194 personnel on active duty and 101,199 in the Navy Reserve. It has 272 deployable combat vessels and more than 3,700 aircraft in active service as of February 2016.

The U.S. Navy traces its origins to the Continental Navy, which was established during the American Revolutionary War and was essentially disbanded as a separate entity shortly thereafter. It played a major role in the American Civil War by blockading the Confederacy and seizing control of its rivers. It played the central role in the World War II defeat of Japan. The 21st century U.S. Navy maintains a sizable global presence, deploying in such areas as East Asia, the Mediterranean, and the Middle East. It is a blue-water navy with the ability to project force onto the littoral regions of the world, engage in forward areas during peacetime, and rapidly respond to regional crises, making it an active player in U.S. foreign and defense policy.

Navy

A navy or maritime force is a fleet of waterborne military vessels (watercraft) and its associated naval aviation, both sea-based and land-based. It is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields; recent developments have included space-related operations. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of Submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications (brown-water navy), open-ocean applications (blue-water navy), and something in between (green-water navy), although these distinctions are more about strategic scope than tactical or operational division.

Ship

A ship is a large buoyant watercraft. Ships are generally distinguished from boats based on size, shape and cargo or passenger capacity. Ships are used on lakes, seas,rivers,and oceans for a variety of activities, such as the transport of people or goods, fishing, entertainment, public safety, and warfare. Historically, a "ship" was a sailing vessel with at least three square-rigged masts and a full bowsprit.

In armed conflict and in daily life, ships have become an integral part of modern commercial and military systems. Fishing boats are used by millions of fishermen throughout the world. Military forces operate vessels for naval warfare and to transport and support forces ashore. Commercial vessels, nearly 35,000 in number, carried 7.4 billion tons of cargo in 2007. As of 2011, there are about 104,304 ships with IMO numbers in the world.

Ships were always a key in history's great explorations and scientific and technological development. Navigators such as Zheng He spread such inventions as the compass and gunpowder. Ships have been used for such purposes as colonization and the slave trade, and have served scientific, cultural, and humanitarian needs. After the 16th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to the world population growth.Ship transport has shaped the world's economy into today's energy-intensive pattern.

Indian Navy

The Indian Navy (IN; Hindi: भारतीय नौ सेना (Devanāgarī), Bhāratīya Nau Senā (Latin)) is the naval branch of the armed forces of India. The President of India serves as the Commander-in-Chief of the Navy. The Chief of Naval Staff (CNS), usually a four-star officer in the rank of Admiral, commands the navy. The Indian Navy is the fifth largest in the world. It played an important role in India's victory in the 1971 Indo-Pakistani War.

The Indian Navy can trace its lineage back to the Honourable East India Company's Marine which was founded in 1612 to protect British merchant shipping in the region. In 1757 the East India Company established its rule over much of the Indian subcontinent, but it wasn't until 1830 that the colonial navy became known as Her Majesty's Indian Navy. In 1858, East India Company rule gave way to the British Raj which lasted until India became independent in 1947. When India became a republic in 1950, the Royal Indian Navy as it had been named since 1934 was renamed to Indian Navy. The 17th-century Maratha emperor Chhatrapati Shivaji Maharaj is considered as the 'Father of the Indian Navy'.

Russian Navy

The Russian Navy (Russian: Военно-морской Флот Российской Федерации (ВМФ России), tr. Voyenno-morskoy Flot Rossiyskoy Federatsii (VMF Rossii), lit. Military-Maritime Fleet of the Russian Federation) is the naval arm of the Russian Armed Forces. The present Russian Navy was formed in January 1992, succeeding the Navy of the Commonwealth of Independent States, which had itself succeeded the Soviet Navy following the dissolution of the Soviet Union in December 1991.

The regular Russian Navy was established by Peter the Great (Peter I) in October 1696. Ascribed to Peter I is the oft quoted statement: "A ruler that has but an army has one hand, but he who has a navy has both." The symbols of the Russian Navy, the St. Andrew's flag and ensign (seen to the right), and most of its traditions were established personally by Peter I.

Neither Jane's Fighting Ships nor the International Institute for Strategic Studies list any standard ship prefixes for the vessels of the Russian Navy. For official U.S. Navy photographs, they are sometimes referred to as "RFS"—"Russian Federation Ship". However, the Russian Navy does not use this convention for itself.
