Indian Navy
The Indian Navy is the maritime branch of the Indian Armed Forces. The President of India is the Supreme Commander of the Indian Navy. The Chief of Naval Staff, a four-star admiral, commands the navy. As a blue-water navy, it operates significantly in the Persian Gulf Region, the Horn of Africa, the Strait of Malacca, and routinely conducts anti-piracy operations with other navies in the region. It also conducts routine two to three month-long deployments in the South and East China seas as well as in the western Mediterranean sea simultaneously.
The primary objective of the navy is to safeguard the nation's maritime borders, and in conjunction with other Armed Forces of the union, act to deter or defeat any threats or aggression against the territory, people or maritime interests of India, both in war and peace. Through joint exercises, goodwill visits and humanitarian missions, including disaster relief, the Indian Navy promotes bilateral relations between nations. Since October 2008, the Indian Navy keeps at least one frontline warship on continuous deployment in the Gulf of Aden.
As of June 2019, the Indian Navy has 67,252 active and 75,000 reserve personnel in service and has a fleet of 150 ships and submarines, and 300 aircraft. As of 2025, the operational fleet consists of 2 active aircraft carriers and 1 amphibious transport dock, 4 landing ship tanks, 8 landing craft utility, 13 destroyers, 17 frigates, 2 ballistic missile submarines, 17 conventionally-powered attack submarines, 18 corvettes, one mine countermeasure vessel, 4 fleet tankers and numerous other auxiliary vessels, small patrol boats and sophisticated ships. It is considered as a multi-regional power projection blue-water navy.
History
Early maritime history
The maritime history of India dates back 6,000 years to the pre-Indus Valley civilisation. A Kutch mariner's log book from 19th century recorded that the first tidal dock in India was built at Lothal around 2300 BC during the Indus Valley Civilisation, near the present-day harbor of Mangrol on the Gujarat coast. The Rig Veda credits Varuna, the Hindu god of water and the celestial ocean, with knowledge of the ocean routes and describes the use of ships having hundred oars in the naval expeditions by Indians. There are also references to the side wings of a ship called Plava, which stabilise the vessel during storms. Plava are considered to be the precursors of modern-day stabilisers.Alexander the Great, during his campaigns in India, built a harbour at the ancient city of Patala, which has been hyphothzied to be the present day city of Thatta. His army retreated to Mesopotamia using ships built at Sindh. In the period after his conquest, records show that the Emperor of Maurya Empire, Chandragupta Maurya, as a part of his war office, established an Admiralty Division. Many historians from ancient India recorded Indian trade relations. Indian trade reached Java and Sumatra. There were also references to the trade routes of countries in the Pacific and Indian Ocean. India also had trade relations with the Greeks and the Romans. At one instance Roman historian Gaius Plinius Secundus mentioned Indian traders carrying away large masses of gold and silver from Rome, in payment for skins, precious stones, clothes, indigo, sandalwood, herbs, perfumes, and spices.
During 5–10 AD, Kalinga conquered Western Java, Sumatra and Malaya. The Andaman and Nicobar Islands served as an important halt point for trade ships en route to these nations and as well as China.
Middle Ages
Medieval Empires in the Indian subcontinent further developed their naval forces. During 844–848 AD the daily revenue from these nations was expected to be around 200 maunds of gold. During 984–1042 AD, under the reign of Raja Raja Chola I, Rajendra Chola I and Kulothunga Chola I, a naval expedition by the Chola dynasty captured parts of Burma, Sumatra, Sri Lanka, and Malaya, and simultaneously repressed pirate activities by Sumatran warlords.During the 14th and 15th centuries, Indian shipbuilding and maritime abilities skill set exceeded European capabilities at the time. Their ships could carry over a hundred crew and were compartmentalized to limit the effect of damage keeping the ship afloat.
Decline
By the end of 15th century Indian naval power had started to decline, and had reached its low by the time the Portuguese entered India. Soon after they set foot in India, the Portuguese started to seize all Asian vessels not permitting their trade. Amidst this, in 1529, a naval war at Bombay Harbour resulted in the surrender of Thane, Karanja, and Bandora. By 1534, the Portuguese took complete control over Bombay Harbour. The Zamorin of Calicut challenged the Portuguese trade when Vasco da Gama refused to pay the customs levy as per the trade agreement. This resulted in two major naval wars, the first one—Battle of Cochin, was fought in 1504, and the second engagement happened four years later off Diu. Both these wars exposed the weakness of Indian maritime power and simultaneously helped the Portuguese to gain mastery over the Indian waters. However, in 1526 the Zamorin launched the siege of Calicut on the Portuguese forts in Calicut, successfully eliminating Portuguese influence in the city.Later revival
By the later seventeenth century Indian naval power revived. The Mughal Empire maintained a significant naval fleet although it was the weakest branch of the military.Empress Mariam-uz-Zamani maintained large fleets of trade ships including the Rahīmī and Ganj-i-Sawai. The Rahimi was the largest of the Indian ships trading in the Red Sea. After being sacked by pirates, this ship was replaced by the Ganj-i-Sawa. This ship was eventually sacked by English Pirate Henry Every. The Navy mainly patrolled coastal areas. The navy was active in the Siege of Hooghly and the Anglo-Mughal War. One of the best-documented naval campaign of the Mughal empire were provided during the conflict against kingdom of Arakan, where in December 1665, Aurangzeb dispatched Shaista Khan, his governor of Bengal to command 288 vessels and more than 20,000 men to pacify the pirate activities within Arakan territory and to capture Chittagong,File:Mahratta pirates attacking the sloop 'Aurora', of the Bombay Marine, 1812; end of the action RMG BHC1085.tiff|thumb|left|A depiction of a Maratha naval attack in 1812 against the East India Company's ship Aurora.
The Maratha Confederacy had a significant coastal navy. The alliance of the Moghuls and the Sidis of Janjira was marked as a major power on the west coast. On the southern front, the 1st Sovereign of the Maratha Kingdom, Chhatrapati Shivaji Maharaj, started creating his own fleet. His fleet was commanded by notable admirals like Sidhoji Gujar and Kanhoji Angre. The Maratha Navy under the leadership of Angre kept the English, Dutch and Portuguese away from the Konkan coast. However, the Marathas witnessed remarkable decline in their naval capabilities following the death of Angre in 1729.
The origins of the current Indian Navy date to 1612, when an English vessel under the command of Captain Thomas Best defeated the Portuguese at the Battle of Swally. Although the Portuguese were defeated, this incident along with the trouble caused by the pirates to the merchant vessels, forced the British to maintain fleet near Surat, Gujarat. East India Company formed a naval arm, and the first squadron of fighting ships reached the Gujarat coast on 5 September 1612. Their objective was to protect British merchant shipping off the Gulf of Cambay and up the Narmada and Tapti rivers. As the HEIC continued to expand its rule and influence over different parts of India, the responsibility of Company's Marine increased too.
Over time, the British predominantly operated from Bombay, and in 1686, the HEIC's naval arm was renamed the Bombay Marine. At times the Bombay Marine engaged Dutch, French, Maratha, and Sidi vessels. Much later, it was also involved in the First Anglo-Burmese War of 1824.
East India Company to independence
In 1834, the Bombay Marine became Her Majesty's Indian Navy. The Navy saw action in the First Opium War of 1840 and in the Second Anglo-Burmese War in 1852. Due to some unrecorded reasons, the Navy's name reverted to the Bombay Marine from 1863 to 1877, after which it was named Her Majesty's Indian Marine. At that time, the Marine operated in two divisions—the Eastern Division at Calcutta under the Superintendent of Bay of Bengal, and the Western Division at Bombay Superintendent of Arabian Sea.In 1892, the Marine was renamed the Royal Indian Marine, and by the end of the 19th century it operated over fifty ships. The Marine participated in World War I with a fleet of patrol vessels, troop carriers, and minesweepers. In 1928, D. N. Mukherji was the first Indian to be granted a commission, in the rank of an Engineer Sub-lieutenant. Also in 1928, the RIM was accorded combatant status, which entitled it to be considered a true fighting force and to fly the White Ensign of the Royal Navy. In 1934, the Marine was upgraded to a full naval force, thus becoming the Royal Indian Navy, and was presented the King's colours in recognition of its services to the British Crown.
During the early stages of World War II, the tiny Royal Indian Navy consisted of five sloops, one survey vessel, one depot ship, one patrol vessel and numerous assorted small craft; personnel strength was at only 114 officers and 1,732 sailors. The onset of war led to an expansion in numbers of vessels and personnel. By June 1940, the navy had doubled its number in terms of both personnel and material, and expanded nearly six times of its pre-war strength by 1942. The navy was actively involved in operations during the war around the world and was heavily involved in operations around the Indian Ocean, including convoy escorts, mine-sweeping and supply, as well as supporting amphibious assaults.
When hostilities ceased in August 1945, the Royal Indian Navy had expanded to a personnel strength of over 25,000 officers and sailors. Its fleet comprised seven sloops, four frigates, four corvettes, fourteen minesweepers, sixteen trawlers, two depot ships, thirty auxiliary vessels, one hundred and fifty landing craft, two hundred harbour craft and several offensive and defensive motor launches. During World War II the Navy suffered two hundred and seventy five casualties—twenty seven officers, two warrant officers and 123 ratings killed in action, two ratings missing in action and a further 14 officers, two warrant officers and 123 ratings wounded. For their role in the war, the officers and ratings of the Navy received the following honours and decorations—a KBE, a knighthood, a CB, 10 CIEs, two DSOs, a CBE, 15 DSCs, an OBE, 28 DSMs, eight OBIs, two IOMs, 16 BEMs, 10 Indian Defence Service Medals, a Royal Humane Society Medal, 105 mentions in dispatches and 118 assorted commendations. Immediately after the war, the navy underwent a rapid, large-scale demobilisation of vessels and personnel.
From the inception of India's naval force, some senior Indian politicians had voiced concerns about the degree of "Indianisation" of the Navy and its subordination to the Royal Navy in all important aspects. On the eve of WWII, the RIN had no Indian senior line officers and only a single Indian senior engineer officer. Even by the war's end, the Navy remained a predominantly British-officered service; in 1945, no Indian officer held a rank above engineer commander and only a few Indian officers in the executive branch held substantive senior line officer rank. This situation, coupled with inadequate levels of training and discipline, poor communication between officers and ratings, instances of racial discrimination and the ongoing trials of ex-Indian National Army personnel ignited the Royal Indian Navy mutiny by Indian ratings in 1946. A total of 78 ships, 20 shore establishments and 20,000 sailors were involved in the strike, which spread over much of India. After the strike began, the sailors received encouragement and support from the Communist Party in India; unrest spread from the naval ships, and led to student and worker hartals in Bombay. The strike ultimately failed as the sailors did not receive substantial support from either the Indian Army or from political leaders in Congress or the Muslim League. On 21 July 1947, H.M.S. Choudhry and Bhaskar Sadashiv Soman, both of whom would eventually command the Pakistani and Indian Navies, respectively, became the first Indian RIN officers to attain the acting rank of captain.
