Introduction

The navy's strategic offensive function is to project force outside of a country's borders. The strategic purpose of a navy's defense is to keep enemies from projecting force from the sea. Nuclear deterrence by submarine-launched ballistic missiles could be part of the navy's strategic mandate.

The phrase previously applied to both commercial and military fleets. The term "navy" now refers to a military fleet, although the term "commercial navy" for a merchant fleet still includes the non-military definition. The crucial dual-use character of fleets generated this overlap in word definitions; centuries ago, nationality was a feature that unified a fleet for both civic and military objectives.

Before 20th-century military technology, installing cannon and naval infantry to any sailing vessel could make it completely as martial as any military-owned vessel, the latter was especially significant and common. Privateering has been proven obsolete in blue-water tactics as contemporary missile and aircraft weapons have advanced to the point that they can outperform artillery and infantry in many ways; yet privateering remains significant in confined and asymmetric coastal combat.

Humans originally battled from water-borne vessels, which led to the development of naval warfare. Before the arrival of the cannon and ships capable of carrying them, navy warfare consisted mostly of ramming and boarding battles.

The Navy's Function

In today's world, a country's fleet serves a dual purpose. It defends sea passages and assaults other navies during wartime. During times of peace, the navy guards trading ports and cargo ships, as well as maintaining security in territorial waters.

The navy, like the army and the air force, is a multi-purpose force. With aircraft carriers, warships, and submarines in its fleet. Its amphibious vehicles are meant to deploy troops and armored vehicles to hostile coasts or to engage the adversary on its soil.

China is rapidly establishing itself as a global actor, with battleships and submarines being built at a breakneck pace. Though it has a larger fleet than the United States, it is not as sophisticated, but its rapid expansion demonstrates that it has the potential to threaten the world's most powerful navy.

4. Japan Navy

The Japan Maritime Self-Defense Force (JMSDF) has 50 800 men, 150 ships, and 346 aircraft in its navy. The constitution of Japan limits the Maritime Self-Defense Force to a defensive doctrine.

It has access to the most advanced warships and submarines available. Furthermore, the Japanese navy is well-maintained and highly effective.

The Japanese navy has no aircraft carriers, however, it does have two large Izumo class and two Hyuga class helicopter carriers. Amphibious ships with anti-surface, anti-submarine, and anti-surface capabilities. With these massive helicopter carriers, the Maritime Self-Defense Force can project a lot of force. As a response to China's fast fleet buildup, the Izumo class warships were announced in 2018 to be converted into aircraft carriers.

The Japanese navy possesses 26 destroyers, including two gigantic Atago class anti-air warfare destroyers and four large Kongou class general-purpose destroyers. These warships are comparable to cruisers in size. The Aikizuki class also includes four general-purpose destroyers.

There are about eleven frigates and six light destroyer escorts present (corvettes).

The JMSDF has three major landing ships at its disposal. Japan's marines are modest, with just over 3000 personnel. The official mission of the Japanese marines is to counter-attack and reclaim seized islands. Despite this, Japan's expeditionary forces are gradually growing in strength.

Intriguingly, these are diesel-powered attack submarines. While Japan does not have nuclear-powered military warships, it does have extremely potent diesel-powered boats with considerable range and offensive potential. In contrast, Japan lacks both ballistic missile submarines and nuclear ballistic missiles.

5. The United Kingdom

The United Kingdom's Royal Navy is known by its formal name. The Royal Navy is one of the world's most capable blue-water fleets, focusing on amphibious operations at the moment. Despite this, due to declining funding, it is rapidly shrinking in size and number of vessels. Approximately 33 000 people work for the Royal Navy.

The Royal Navy only possesses one Queen Elizabeth-class aircraft carrier.

The British navy has six anti-air warfare destroyers of the daring class. These ships can patrol broad regions and supply the fleet with air defense.

Around 7,700 people make up this brigade. The Royal Marines are the European Union's most powerful naval infantry unit. Two Albion class landing ships and three Bay class logistics landing ships are moored alongside.

The Royal Navy also has four ballistic missile submarines of the Vanguard-class. Each of these boats can carry 192 nuclear bombs. Such a weight is capable of wiping out entire countries. At any one time, a single Vanguard-class boat is on deterrent patrol. The specifics of these patrols are remained classified.

Various naval helicopters are used by the British Fleet Air Arm for search and rescue, anti-submarine warfare, utility, and other missions.

6. France

The Marine Nationale de France is one of the oldest naval units in the world. It currently employs roughly 36 000 people.

The Charles de Gaulle is the lone aircraft carrier in the French navy. It is, nevertheless, far smaller than the carriers in the United States.

There are two modern anti-air warfare destroyers of the Horizon class. Frigates are the official name for these ocean-going warships. These ships, however, are certainly destroyers due to their size and strong armament. For political reasons, these are referred to as frigates. There are also two older Cassard class destroyers and four Georges Leygues class destroyers scheduled to be retired soon.

The French navy has four guided-missile frigates of the Aquitaine class. This class of vessels is being manufactured in greater numbers. There are 5 frigates of the La Fayette class and 6 frigates of the Floreal class.

The French navy has three amphibious assault ships of the Mistral-class. After the Charles de Gaulle aircraft carrier, these are the largest warships. Amphibious landing operations are the primary mission of these ships. They can also provide command and control and force projection. A naval infantry brigade with a strength of roughly 8000 troops is part of the French navy. These are expeditionary forces that may land on hostile coasts and launch armoured raids into enemy territory up to 100 kilometres away.

The French navy has four ballistic missile submarines of the Le Triomphant class, which serve as the backbone of the country's nuclear deterrent.

7. India

Approximately 67 000 individuals work for the Indian Navy. It is a strong force in South Asia. Its equipment is gradually improving, and it is evolving from a coastline to an ocean-going force

The INS Vikramaditya is the lone aircraft carrier in the Indian Navy. This ship has a limited number of aircraft. An aircraft carrier being built in India, the INS Vikrant, is anticipated to be operational soon. It will boost India's capacity to project force significantly.

Three destroyers of the Delhi series and five destroyers of the earlier Rajput class are also present.

Three previous Brahmaputra class frigates and one Godavari class frigate are also present. To protect the oceans, roughly 20 corvettes are stationed around the coast.

The INS Jalashwa is the Indian Navy's largest amphibious transport ship, with eight smaller landing craft (3 Shardul class, 2 Magar class, 3 Kumbhir class). These ships are built to transport troops and weapons to hostile shores or to conduct a counter-offensive against occupied Indian shores. India, on the other hand, lacks a specialized marine infantry due to a lack of crucial equipment.

The Indian Navy only possesses one Arihant-class ballistic missile submarine. The class's second boat will be launched shortly. It was a turning point in the evolution of the Indian Navy. India has entered a group of five countries capable of designing and manufacturing nuclear submarines.

In the fleet, there is only one nuclear-powered attack submarine. These are modified Scorpene-class boats built for the Indian Navy by a Franco-Spanish company. Three more boats are being built, and the lead boat has been commissioned. Two other boats are expected to be ready soon. The Indian Navy also has nine Sindhughosh class diesel-powered patrol submarines. Kilo-class boats from the Cold War era of the Soviet Union. There are four Shisumar class (German Type 206 class) diesel-powered boats in operation.

There are around 210 aircraft in the Indian Naval Air Arm.

8. South Korea

A few decades ago, the South Korean navy was almost unknown. It was, however, subsequently upgraded from a coastal to an ocean-capable force. It presently has 70 000 employees.

There are no aircraft carriers in the South Korean navy. Only one amphibious assault ship of the Dokdo class is available. It's about the same size as a small aircraft carrier. It is the South Korean navy's flagship. Another ship of this class is now under construction, with a 2020 commissioning date. Three guided-missile destroyers make up the Sejong the Great class. These are some of the most technologically advanced ships ever built. After the American Zumwalt class destroyers, they are presently the world's most capable destroyers. The Sejong the Great class ships are armed with a diverse range of missiles, allowing them to cope with practically any danger on land, at sea, or in the air.

There is presently only one Daegu class air defence frigate in service, which was commissioned in 2018. Three further warships of this class are currently under construction. There are also six Incheon-class coastal defence frigates. The South Korean navy has six old Ulsan class frigates from the 1980s and 1990s. However, these older ships are set to be decommissioned in the nearish term. The South Korean navy has seven diesel-powered submarines of the Type 214 class (also known as the Sohn Won-yil class) with air-independent propulsion systems. There are also nine earlier Chang Bogo class diesel submarines.

The Cheong Wang Bong class has two active amphibious landing ships. Two more ships in this class are currently under construction. The Go Jun Bong class includes four amphibious landing ships.

Around 70 aircraft make up South Korea's naval aviation. The majority of these are helicopters. Even though there are 16 Lockheed Martin P-3C Orion maritime patrol planes.

9. Italy

The Italian navy (formally Marina Militare Italiana) has an ocean-going fleet and employs approximately 31 000 people. The Italian navy has a diverse fleet of warships.

The Italian navy has two destroyers of the Horizon class. These warships are officially referred to be frigates for political reasons. These ships, however, are certainly destroyers due to their size and strong armament. There are also two older multi-role destroyers of the Durand de la Penne class. The Marina Militare currently employs six smaller Carlo Bergamini class guided-missile destroyers, with four more on the way. These ships are also known as frigates, but they are far larger and more powerful than other frigates and even destroyers around the globe.

There are six operating anti-submarine frigates of the Maestrale class. There are two smaller patrol frigates of the Soldati class.

There are four diesel-powered patrol submarines of the Salvatore Torado class (German Type 212 class) and four earlier Sauro class diesel-powered patrol submarines.

The Italian Navy has a total of 2 000 men and a dozen AV-8B Harrier II close support aircraft. Onboard Italian aircraft ships, another 29-30 F-35B multi-role fighters have been requested.

10. Taiwan

The Taiwanese navy has a workforce of 38 000 persons. The majority of the warships are supplied by the United States. Some of the warships were supplied by other countries. Taiwan is also capable of building ships on its own.

The Kee Lung class consists of four destroyers. These are destroyers from the Kidd class of the United States Navy.

The Taiwanese navy has a total of 20 frigates. There are eight frigates of the Cheng Kung class among them. Six frigates of the Chi Yang class (originally the US Knox class) and six frigates of the Knag Ding class (French-built La Fayette class) are in service.

The Taiwanese navy has only two useful Hai Lung class submarines.

Taiwanese navy aviation operates 12 refurbished and modernized P-3C Orion maritime patrol aircraft.
