Australia , officially the Commonwealth of Australia , is a sovereign country comprising the mainland of the Australian continent , the island of Tasmania , and numerous smaller islands . It is the largest country in Oceania and the world 's sixth-largest country by total area . The population of 26 million is highly urbanised and heavily concentrated on the eastern seaboard . Australia 's capital is Canberra , and its largest city is Sydney . The country 's other major metropolitan areas are Melbourne , Brisbane , Perth , and Adelaide . Indigenous Australians inhabited the continent for about 65,000 years prior to the first arrival of Dutch explorers in the early 17th century , who named it New Holland . In 1770 , Australia 's eastern half was claimed by Great Britain and initially settled through penal transportation to the colony of New South Wales from 26 January 1788 , a date which became Australia 's national day . The population grew steadily in subsequent decades , and by the time of an 1850s gold rush , most of the continent had been explored and an additional five self-governing crown colonies established . On 1 January 1901 , the six colonies federated , forming the Commonwealth of Australia . Australia has since maintained a stable liberal democratic political system that functions as a federal parliamentary constitutional monarchy , comprising six states and ten territories . Australia is the oldest , flattest , and driest inhabited continent , with the least fertile soils . It has a landmass of 7,617,930 square kilometres ( 2,941,300 sq mi ) .
The Royal Australian Navy ( RAN ) is the naval branch of the Australian Defence Force . Following the Federation of Australia in 1901 , the ships and resources of the separate colonial navies were integrated into a national force , called the Commonwealth Naval Forces . Originally intended for local defence , the navy was granted the title of 'Royal Australian Navy ' in 1911 , and became increasingly responsible for defence of the region . Britain 's Royal Navys Australian Squadron was assigned to the Australia Station and provided support to the RAN . The Australian and New Zealand governments helped to fund the Australian Squadron until 1913 , while the Admiralty committed itself to keeping the Squadron at a constant strength . The Australian Squadron ceased on 4 October 1913 , when RAN ships entered Sydney Harbour for the first time . The Royal Navy continued to provide blue-water defence capability in the Pacific up to the early years of the Second World War . Then , rapid wartime expansion saw the acquisition of large surface vessels and the building of many smaller warships . In the decade following the war , the RAN acquired a small number of aircraft carriers , the last of which was decommissioned in 1982 . Today , the RAN consists of 48 commissioned vessels , 3 non-commissioned vessels and over 16,000 personnel . The navy is one of the largest and most sophisticated naval forces in the South Pacific region , with a significant presence in the Indian Ocean and worldwide operations in support of military campaigns and peacekeeping missions . The current Chief of Navy is Vice Admiral Michael Noonan .
Brazil ( Portuguese : Brasil ; Portuguese pronunciation : [ bɾaˈziw ] ) , [ nt 1 ] officially the Federative Republic of Brazil ( Portuguese : República Federativa do Brasil , listen ( help·info ) ) , is the largest country in both South America and Latin America . At 8.5 million square kilometers ( 3.2 million square miles ) and with over 211 million people , Brazil is the world 's fifth-largest country by area and the sixth most populous . Its capital is Brasília , and its most populous city is São Paulo . The federation is composed of the union of the 26 states , the Federal District , and the 5,570 municipalities . It is the largest country to have Portuguese as an official language and the only one in the Americas ; it is also one of the most multicultural and ethnically diverse nations , due to over a century of mass immigration from around the world . Bounded by the Atlantic Ocean on the east , Brazil has a coastline of 7,491 kilometers ( 4,655 mi ) . It borders all other countries in South America except Ecuador and Chile and covers 47.3% of the continent 's land area . Its Amazon River basin includes a vast tropical forest , home to diverse wildlife , a variety of ecological systems , and extensive natural resources spanning numerous protected habitats . This unique environmental heritage makes Brazil one of 17 megadiverse countries , and is the subject of significant global interest and debate regarding deforestation and environmental protection . Brazil was inhabited by numerous tribal nations prior to the landing in 1500 of explorer Pedro Álvares Cabral , who claimed the area for the Portuguese Empire . Brazil remained a Portuguese colony until 1808 , when the capital of the empire was transferred from Lisbon to Rio de Janeiro . In 1815 , the colony was elevated to the rank of kingdom upon the formation of the United Kingdom of Portugal , Brazil and the Algarves .
The Brazilian Navy ( Portuguese : Marinha do Brasil ) is the naval service branch of the Brazilian Armed Forces , responsible for conducting naval operations . The Brazilian Navy is the largest navy in South America and in Latin America , and the second largest navy in the Americas , after the United States Navy . The navy was involved in Brazil 's war of independence from Portugal . Most of Portugal 's naval forces and bases in South America were transferred to the newly independent country . In the initial decades following independence , the country maintained a large naval force and the navy was later involved in the Cisplatine War , the River Plate conflicts , the Paraguayan War as well as other sporadic rebellions that marked Brazilian history . By the 1880s the Brazilian Imperial Navy was the most powerful in South America . After the 1893 naval rebellion , there was a hiatus in the development of the navy until 1905 , when Brazil acquired two of the most powerful and advanced dreadnoughts of the day which sparked a dreadnought race with Brazil 's South American neighbours . The Brazilian Navy participated in both World War I and World War II , engaging in anti-submarine patrols in the Atlantic . The modern Brazilian Navy includes British-built guided missile frigates ( FFG ) , locally built corvettes ( FFL ) , coastal diesel-electric submarines ( SSK ) and many other river and coastal patrol craft .
China ( Chinese : 中国 ; pinyin : Zhōngguó ) , officially the People 's Republic of China ( PRC ) , is a country in East Asia and is the world 's most populous country , with a population of around 1.428 billion in 2017 . Covering approximately 9,600,000 square kilometers ( 3,700,000 sq mi ) , it is the third largest country by area . [ j ] Governed by the Communist Party of China , the state exercises jurisdiction over 22 provinces , [ k ] five autonomous regions , four direct-controlled municipalities ( Beijing , Tianjin , Shanghai , and Chongqing ) , and the special administrative regions of Hong Kong and Macau . China emerged as one of the world 's first civilizations , in the fertile basin of the Yellow River in the North China Plain . For millennia , China 's political system was based on hereditary monarchies , or dynasties , beginning with the semi-mythical Xia dynasty in 21st century BCE . Since then , China has expanded , fractured , and re-unified numerous times . In the 3rd century BCE , the Qin reunited core China and established the first Chinese empire . The succeeding Han dynasty , which ruled from 206 BCE until 220 CE , saw some of the most advanced technology at that time , including papermaking and the compass , along with agricultural and medical improvements . The invention of gunpowder and movable type in the Tang dynasty ( 618-907 ) and Northern Song ( 960-1127 ) completed the Four Great Inventions . Tang culture spread widely in Asia , as the new Silk Route brought traders to as far as Mesopotamia and the Horn of Africa . Dynastic rule ended in 1912 with the Xinhai Revolution , when the Republic of China ( ROC ) replaced the Qing dynasty . China , as a whole , was ravaged by feudal warlordism and Japan during World War II .
The People 's Liberation Army Navy ( Chinese : 中国人民解放军海军 ) , also known as the PLA Navy or PLAN , is the naval warfare branch of the People 's Liberation Army , which is the armed wing of the Communist Party of China and , by default , the national armed forces of the People 's Republic of China . The PLAN can trace its lineage to naval units fighting during the Chinese Civil War and was established in September 1950 . Throughout the 1950s and early 1960s , the Soviet Union provided assistance to the PLAN in the form of naval advisers and export of equipment and technology . Until the late 1980s , the PLAN was largely a riverine and littoral force ( brown-water navy ) . However , by the 1990s , following the fall of the Soviet Union and a shift towards a more forward-oriented foreign and security policy , the leaders of the Chinese military were freed from worrying over land border disputes , and instead turned their attention towards the seas . This led to the development of the People 's Liberation Army Navy into a green-water navy by 2009 . Before the 1990s the PLAN had traditionally played a subordinate role to the People 's Liberation Army Ground Force . In 2008 , General Qian Lihua confirmed that China plans to operate a small fleet of aircraft carriers in the near future , but for the purpose of regional defence as opposed to global reach . As of 2013 PLA officials have also outlined plans to operate in the first and second island chains . Chinese strategists term the development of the PLAN from a green-water navy into a regional blue-water defensive and offensive navy . The People 's Liberation Army Navy is composed of five branches ; the Submarine Force , the Surface Force , the Coastal Defense Force , the Marine Corps and the Naval Air Force . With a personnel strength of 255,000 servicemen and women , including 10,000 marines and 26,000 naval air force personnel , it is the second largest navy in the world in terms of tonnage , only behind the United States Navy , and has the largest number of major combatants of any navy .
Egypt ( /ˈiːdʒɪpt/ ( listen ) EE-jipt ; Arabic : مِصر Miṣr , Egyptian Arabic : مَصر Maṣr , Coptic : Ⲭⲏⲙⲓ Khēmi ) , officially the Arab Republic of Egypt , is a country spanning the northeast corner of Africa and southwest corner of Asia by a land bridge formed by the Sinai Peninsula . Egypt is a Mediterranean country bordered by the Gaza Strip ( Palestine ) and Israel to the northeast , the Gulf of Aqaba and the Red Sea to the east , Sudan to the south , and Libya to the west . Across the Gulf of Aqaba lies Jordan , across the Red Sea lies Saudi Arabia , and across the Mediterranean lie Greece , Turkey and Cyprus , although none share a land border with Egypt . Egypt has one of the longest histories of any country , tracing its heritage back to the 6th-4th millennia BCE . Considered a cradle of civilisation , Ancient Egypt saw some of the earliest developments of writing , agriculture , urbanisation , organised religion and central government . Iconic monuments such as the Giza Necropolis and its Great Sphinx , as well the ruins of Memphis , Thebes , Karnak , and the Valley of the Kings , reflect this legacy and remain a significant focus of scientific and popular interest . Egypt 's long and rich cultural heritage is an integral part of its national identity , which has endured , and often assimilated , various foreign influences , including Greek , Persian , Roman , Arab , Ottoman Turkish , and Nubian . Egypt was an early and important centre of Christianity , but was largely Islamised in the seventh century and remains a predominantly Muslim country , albeit with a significant Christian minority . From the 16th to the beginning of the 20th century , Egypt was ruled by foreign imperial powers : The Ottoman Empire and the British Empire . Modern Egypt dates back to 1922 , when it gained nominal independence from the British Empire as a monarchy . However , British military occupation of Egypt continued , and many Egyptians believed that the monarchy was an instrument of British colonialism . Following the 1952 revolution , Egypt expelled British soldiers and bureaucrats and ended British occupation , nationalized the British-held Suez Canal , exiled King Farouk and his family , and declared itself a republic .
The Egyptian Navy ( Arabic : القوات البحرية المصرية , lit . Egyptian Navy Forces ) , also known as the Egyptian Naval Force , is the maritime branch of the Egyptian Armed Forces . It is the largest navy in the Middle East and Africa , and is the sixth largest in the world measured by the number of vessels . The navy 's missions include protection of more than 2,000 kilometers of coastline of the Mediterranean Sea and the Red Sea , defense of approaches to the Suez Canal , and support for army operations . The majority of the modern Egyptian Navy was created with the help of the Soviet Union in the 1960s . The navy received ships in the 1980s from China and other , western , sources . In 1989 , the Egyptian Navy had 18,000 personnel as well as 2,000 personnel in the Coast Guard .
France ( French : [ fʁɑ̃s ] ( listen ) ) , officially the French Republic ( French : République française , pronounced [ ʁepyblik fʁɑ̃sɛːz ] ( listen ) ) , is a country whose territory consists of metropolitan France in Western Europe and several overseas regions and territories . [ XIII ] The metropolitan area of France extends from the Mediterranean Sea to the English Channel and the North Sea , and from the Rhine to the Atlantic Ocean . It is bordered by Belgium , Luxembourg and Germany to the northeast , Switzerland and Italy to the east , and Andorra and Spain to the south . The overseas territories include French Guiana in South America and several islands in the Atlantic , Pacific and Indian oceans . The country 's 18 integral regions ( five of which are situated overseas ) span a combined area of 643,801 square kilometres ( 248,573 sq mi ) and a total population of 67.02 million ( as of July 2019 [ update ] ) . France is a unitary semi-presidential republic with its capital in Paris , the country 's largest city and main cultural and commercial centre . Other major urban areas include Lyon , Marseille , Toulouse , Bordeaux , Lille and Nice . France , including its overseas territories , has the most number of time zones of any country , with a total of 12 . During the Iron Age , what is now metropolitan France was inhabited by the Gauls , a Celtic people . Rome annexed the area in 51 BC , holding it until the arrival of Germanic Franks in 476 , who formed the Kingdom of Francia . The Treaty of Verdun of 843 partitioned Francia into East Francia , Middle Francia and West Francia . West Francia , which became the Kingdom of France in 987 , emerged as a major European power in the Late Middle Ages , following its victory in the Hundred Years ' War ( 1337-1453 ) .
The French Navy ( French : Marine Nationale , lit . National Navy ) , informally La Royale , is the maritime arm of the French Armed Forces . Dating back to 1624 , the French Navy is one of the world 's oldest naval forces . It has participated in conflicts around the globe and played a key part in establishing the French colonial empire . The French Navy consists of six main branches and various services : the Force d'Action Navale , the Forces Sous-marines ( FOST , ESNA ) , French Naval Aviation , the Fusiliers Marins ( including Commandos Marine ) , the Marins Pompiers , and the Maritime Gendarmerie . As of June 2014 , the French Navy employed a total of 36,776 personnel along with 2,800 civilians . Its reserve element consisted of 4,827 personnel of the Operational Reserve . As a blue-water navy , it operates a wide range of fighting vessels , which include the nuclear-powered aircraft carrier Charles de Gaulle , various aeronaval forces , attack submarines and ballistic missile submarines , frigates , patrol boats and support ships .
India ( Hindi : Bhārat ) , officially the Republic of India ( Hindi : Bhārat Gaṇarājya ) , is a country in South Asia . It is the seventh-largest country by area , the second-most populous country , and the most populous democracy in the world . Bounded by the Indian Ocean on the south , the Arabian Sea on the southwest , and the Bay of Bengal on the southeast , it shares land borders with Pakistan to the west ; [ e ] China , Nepal , and Bhutan to the north ; and Bangladesh and Myanmar to the east . In the Indian Ocean , India is in the vicinity of Sri Lanka and the Maldives ; its Andaman and Nicobar Islands share a maritime border with Thailand and Indonesia . Modern humans arrived on the Indian subcontinent from Africa no later than 55,000 years ago . Their long occupation , initially in varying forms of isolation as hunter-gatherers , has made the region highly diverse , second only to Africa in human genetic diversity . Settled life emerged on the subcontinent in the western margins of the Indus river basin 9,000 years ago , evolving gradually into the Indus Valley Civilisation of the third millennium BCE . By 1200 BCE , an archaic form of Sanskrit , an Indo-European language , had diffused into India from the northwest , unfolding as the language of the Rigveda , and recording the dawning of Hinduism in India . The Dravidian languages of India were supplanted in the northern regions . By 400 BCE , stratification and exclusion by caste had emerged within Hinduism , and Buddhism and Jainism had arisen , proclaiming social orders unlinked to heredity . Early political consolidations gave rise to the loose-knit Maurya and Gupta Empires based in the Ganges Basin . Their collective era was suffused with wide-ranging creativity , but also marked by the declining status of women , and the incorporation of untouchability into an organised system of belief .
The Indian Navy is the naval 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 . The Indian Navy traces its origins back to the East India Company 's Marine which was founded in 1612 to protect British merchant shipping in the region . In 1793 , the British East India Company established its rule over eastern part of the Indian subcontinent i.e . Bengal , but it was not until 1830 that the colonial navy was titled as His Majesty 's Indian Navy . When India became a republic in 1950 , the Royal Indian Navy as it had been named since 1934 was renamed to Indian Navy . 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 , Indian Navy promotes bilateral relations between nations . As of June 2019 , Indian Navy has 67,252 personnel in service and has a fleet of 137 warships and 235 aircraft . As of March 2018 , the operational fleet consists of one aircraft carrier , one amphibious transport dock , eight landing ship tanks , eleven destroyers , fourteen frigates , one nuclear-powered attack submarine , one ballistic missile submarine , fifteen conventionally-powered attack submarines , twenty-two corvettes , one mine countermeasure vessel , four fleet tankers and various other auxiliary vessels .
Japan ( Japanese : 日本 , Nippon [ ɲippoꜜɴ ] ( listen ) or Nihon [ ɲihoꜜɴ ] ( listen ) ) is an island country located in East Asia . It is bordered by the Sea of Japan to the west and the Pacific Ocean to the east , and spans more than 3,000 kilometers ( 1,900 mi ) along the coast of the continent from the Sea of Okhotsk in the north to the East China Sea and Philippine Sea in the south . Part of the Pacific Ring of Fire , Japan encompasses a stratovolcanic archipelago of about 6,852 islands , with five main islands ( Hokkaido , Honshu , Kyushu , Shikoku , and Okinawa ) comprising 97% of the country 's total area of 377,975 square kilometers ( 145,937 sq mi ) . Japan is officially divided into 47 prefectures and traditionally into eight regions . Approximately two-thirds of the country 's terrain is mountainous and heavily forested , and less than one-eighth of land is suitable for agriculture . Consequently , Japan is among the most densely populated and urbanized countries in the world , with over 90% of its population living in urban areas . The largest of these is the metropolitan area centered on the capital city of Tokyo , which is the most populous in the world and home to more than 38 million people . Japan itself is the world 's eleventh most populous country with a population of 126.2 million , of which 97.8% are ethnically Japanese . The kanji ( or Chinese characters ) that make up the name of Japan in the Japanese language mean sun origin ; in the Western world , the country is often known by the sobriquet Land of the Rising Sun . Periods of influence from other regions , primarily China , followed by periods of isolation , particularly from Western Europe , have characterized the history of Japan . While archaeological evidence indicates that Japan was inhabited as early as the Upper Paleolithic period , the first written mention of the archipelago appears in Chinese texts from the first century AD . Between the fourth and ninth centuries , the kingdoms of Japan became gradually unified under an Emperor and imperial court based in Heian-kyō ( modern Kyoto ) .
The Japan Maritime Self-Defense Force ( 海上自衛隊 , Kaijō Jieitai ) , JMSDF , also referred to as the Japanese navy , is the maritime warfare branch of the Japan Self-Defense Forces , tasked with the naval defense of Japan . The JMSDF was formed following the dissolution of the Imperial Japanese Navy ( IJN ) after World War II . The JMSDF has a fleet of 154 ships and 346 aircraft and consists of approximately 45,800 personnel . Its main tasks are to maintain control of the nation 's sea lanes and to patrol territorial waters . It also participates in UN-led peacekeeping operations ( PKOs ) and Maritime Interdiction Operations ( MIOs ) .
Russia ( Russian : Росси́я , tr . Rossiya , IPA : [ rɐˈsʲijə ] ) , or the Russian Federation , [ e ] is a European country located in Eastern Europe with a vast expanse of territory that stretches across Northern Asia . At 17,125,200 square kilometres ( 6,612,100 sq mi ) , it is by far the largest country in the world by area , covering more than one-eighth of the Earth 's inhabited land area , spanning eleven time zones , and bordering 16 sovereign nations . The territory of Russia extends from the Baltic Sea in the west to the Pacific Ocean in the east , and from the Arctic Ocean in the north to the Black Sea and the Caucasus in the south . With 146.7 million inhabitants living in the country 's 85 federal subjects as of 2020 , Russia is the most populous nation in Europe and the ninth-most populous nation in the world . Russia 's capital and largest city is Moscow ; other major urban areas include Saint Petersburg , Novosibirsk , Yekaterinburg , Nizhny Novgorod , Kazan and Chelyabinsk . The East Slavs emerged as a recognizable group in Europe between the 3rd and 8th centuries AD . Founded and ruled by a Varangian warrior elite and their descendants , the medieval state of Rus arose in the 9th century . In 988 it adopted Orthodox Christianity from the Byzantine Empire , beginning the synthesis of Byzantine and Slavic cultures that defined Russian culture for the next millennium . Rus ultimately disintegrated into a number of smaller states , until it was finally reunified by the Grand Duchy of Moscow in the 15th century . By the 18th century , the nation had greatly expanded through conquest , annexation , and exploration to become the Russian Empire , which was the third largest empire in history , stretching from Poland on the west to Alaska on the east . Following the Russian Revolution , the Russian Soviet Federative Socialist Republic ( Russian SFSR ) became the largest and leading constituent of the Union of Soviet Socialist Republics ( USSR/Soviet Union ) , the world 's first constitutionally socialist state .
The Russian Navy ( Russian : Военно-морской флот Российской Федерации ( ВМФ России ) , lit . Military-Maritime Fleet of the Russian Federation ) is the naval arm of the Russian Armed Forces . It has existed in various forms since 1696 , the present iteration of which was formed in January 1992 when it succeeded the Navy of the Commonwealth of Independent States ( which had itself succeeded the Soviet Navy following the dissolution of the Soviet Union in late December 1991 ) . The first iteration of the Russian Navy was established by Peter the Great ( Peter I ) in October 1696 . Ascribed to him 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 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 . The U.S. government sometimes uses the exonymous prefix RFS ( for Russian Federation Ship ) . However , the Russian Navy itself does not use this convention . The Russian Navy possesses the vast majority of the former Soviet naval forces , and currently comprises the Northern Fleet , the Russian Pacific Fleet , the Russian Black Sea Fleet , the Russian Baltic Fleet , the Russian Caspian Flotilla , Naval Aviation , and the Coastal Troops ( consisting of the naval infantry and the Coastal Missile and Artillery Troops ) . A rearmament program approved in 2007 placed the development of the navy on an equal footing with the strategic nuclear forces for the first time in Soviet and Russian history . This program , covering the period until 2015 , expected to see the replacement of 45 percent of the inventory of the Russian Navy .
South Korea ( Korean : 한국/韓國 ; RR : Hanguk or literally 남한/南韓 ; RR : Namhan ) , officially the Republic of Korea ( Korean : 대한민국/大韓民國 ; RR : Daehan Minguk ) is a country in East Asia , constituting the southern part of the Korean Peninsula and sharing a land border with North Korea . The name Korea is derived from Goguryeo , which was one of the great powers in East Asia during its time , ruling most of the Korean Peninsula , Manchuria , parts of the Russian Far East and Inner Mongolia under Gwanggaeto the Great . Its capital , Seoul , is a major global city and half of South Korea 's over 51 million people live in the Seoul Capital Area , the fourth largest metropolitan economy in the world . The Korean Peninsula was inhabited as early as the Lower Paleolithic period . Its first kingdom was noted in Chinese records in the early 7th century BC . Following the unification of the Three Kingdoms of Korea into Silla and Balhae in the late 7th century , Korea was ruled by the Goryeo dynasty ( 918-1392 ) and the Joseon dynasty ( 1392-1897 ) . The succeeding Korean Empire was annexed into the Empire of Japan in 1910 . After World War II , Korea was divided into Soviet and U.S.-administered zones , with the latter becoming the Republic of Korea in August 1948 . In 1950 , a North Korean invasion began the Korean War and after its end in 1953 , the country 's economy began to soar , recording the fastest rise in average GDP per capita in the world between 1980 and 1990 . Authoritarian rule ended in 1987 and the country is now the most advanced democracy with the highest level of press freedom in Asia . South Korea is a member of the OECD 's Development Assistance Committee , the G20 and the Paris Club . South Korea is a highly developed country and the world 's 12th-largest economy by nominal GDP .
The Republic of Korea Navy ( ROKN ; Korean : 대한민국 해군 ) , also known as the ROK Navy or South Korean Navy , is the naval warfare service branch of the South Korean armed forces , responsible for naval and amphibious operations . The ROK Navy includes the Republic of Korea Marine Corps , which functions as a branch of the Navy . The ROK Navy has about 70,000 regular personnel including 29,000 Republic of Korea Marines . There are about 150 commissioned ships with the ROK Navy . The naval aviation force consists of about 70 fixed-wing and rotary-wing aircraft . The ROK Marine Corps has about 300 tracked vehicles including assault amphibious vehicles . The Republic of Korea Navy was established as the Marine Defense Group on November 11 , 1945 after Korea was liberated from the Empire of Japan on August 15 , 1945 . Since the Korean War , the South Korean navy had concentrated its efforts on building naval forces to counteract the North Korean navy . As South Korea 's economy grew , the ROK Navy was able to locally build larger and better equipped fleets to deter aggression , to protect the sea lines of communication , and to support the nation 's foreign policy . As part of its mission , the ROK Navy has engaged in several peacekeeping operations since the turn of the 21st century . The ROK Navy aims to become a blue-water navy in the 2020s .
Spain ( Spanish : España [ esˈpaɲa ] ( listen ) ) , officially the Kingdom of Spain ( Spanish : Reino de España ) , [ a ] [ b ] is a country in Southwestern Europe with some pockets of Spanish territory across the Strait of Gibraltar and the Atlantic Ocean . Its continental European territory is situated on the Iberian Peninsula . Its territory also includes two archipelagoes : the Canary Islands off the coast of Africa , and the Balearic Islands in the Mediterranean Sea . The African enclaves of Ceuta , Melilla , and Peñón de Vélez de la Gomera make Spain the only European country to have a physical border with an African country ( Morocco ) . [ h ] Several small islands in the Alboran Sea are also part of Spanish territory . The country 's mainland is bordered to the south and east by the Mediterranean Sea except for a small land boundary with Gibraltar ; to the north and northeast by France , Andorra , and the Bay of Biscay ; and to the west and northwest by Portugal and the Atlantic Ocean . With an area of 505,990 km2 ( 195,360 sq mi ) , Spain is the largest country in Southern Europe , the second largest country in Western Europe and the European Union , and the fourth largest country in the European continent . By population ( about 47 million ) , Spain is the sixth largest in Europe and the fifth in the European Union . Spain 's capital and largest city is Madrid ; other major urban areas include Barcelona , Valencia , Seville , Zaragoza , Málaga and Bilbao . Modern humans first arrived in the Iberian Peninsula around 35,000 years ago . Iberian cultures along with ancient Phoenician , Greek , Celtic and Carthaginian settlements developed on the peninsula until it came under Roman rule around 200 BCE , after which the region was named Hispania , based on the earlier Phoenician name Sp ( a ) n or Spania . At the end of the Western Roman Empire the Germanic tribal confederations migrated from Central Europe , invaded the Iberian peninsula and established relatively independent realms in its western provinces , including the Suebi , Alans and Vandals .
The Spanish Navy ( Spanish : Armada Española ) is the maritime branch of the Spanish Armed Forces and one of the oldest active naval forces in the world . The Spanish navy was responsible for a number of major historic achievements in navigation , the most famous being the discovery of America by Spain and the first global circumnavigation by Magellan and Elcano . For several centuries , it played a crucial logistical role in the Spanish Empire and defended a vast trade network across the Atlantic Ocean between the Americas and Europe and across the Pacific Ocean between Asia and the Americas . The Spanish Navy was the most powerful maritime force in the world in the 16th and 17th centuries and possibly the world 's largest navy at the end of the 16th century and in the early 17th century [ vague ] . Reform under the Bourbon dynasty improved its logistical and military capacity in the 18th century , for most of which Spain possessed the world 's third largest navy . In the 19th century , the Spanish Navy built and operated one of the first military submarines , made important contributions in the development of destroyer warships , and again achieved a first global circumnavigation , this time by an ironclad vessel . Today the Spanish Navy is one of the most important in the world , and one of the only nine naval forces on the planet capable of projecting an important level of force in their own hemisphere The main bases of the Spanish Navy are located in Rota , Ferrol , San Fernando and Cartagena .

Its maritime boundaries include Vietnam in the Gulf of Thailand to the southeast , and Indonesia and India on the Andaman Sea to the southwest . It is a unitary state . Although nominally the country is a constitutional monarchy and parliamentary democracy , the most recent coup , in 2014 , established a de facto military dictatorship under a junta . Tai peoples migrated from southwestern China to mainland Southeast Asia from the 11th century ; the oldest known mention of their presence in the region by the exonym Siamese dates to the 12th century . Various Indianised kingdoms such as the Mon kingdoms , Khmer Empire and Malay states ruled the region , competing with Thai states such as the Kingdoms of Ngoenyang , Sukhothai , Lan Na and Ayutthaya , which rivaled each other . Documented European contact began in 1511 with a Portuguese diplomatic mission to Ayutthaya , now one of the great powers in the region . Ayutthaya reached its peak during cosmopolitan Narai 's reign ( 1656-1688 ) , gradually declining thereafter until being ultimately destroyed in the 1767 Burmese-Siamese War . Taksin ( r. 1767-1782 ) quickly reunified the fragmented territory and established the short-lived Thonburi Kingdom .

Turkey ( Turkish : Türkiye [ ˈtyɾcije ] ) , officially the Republic of Turkey ( Turkish : Türkiye Cumhuriyeti [ ˈtyɾcije dʒumˈhuːɾijeti ] ( listen ) ) , is a transcontinental country located mostly on the Anatolian peninsula in Western Asia , with a smaller portion on the Balkan peninsula in Southeastern Europe . East Thrace , the part of Turkey in Europe , is separated from Anatolia by the Sea of Marmara , the Bosporus and the Dardanelles ( collectively called the Turkish Straits ) . Istanbul , mostly located on the European side , is the largest city in the country while Ankara is the capital . Turkey is bordered by Greece and Bulgaria to its northwest , the Black Sea to its north , Georgia to its northeast , Armenia , the Azerbaijani exclave of Nakhchivan and Iran to its east , Iraq and Syria to its southeast , the Mediterranean Sea to its south , and the Aegean Sea to its west . Approximately 70 to 80 percent of the country 's citizens identify as Turkish , while Kurds are the largest minority at anywhere from 15 to 20 percent of the population . At various points in its history , the region has been inhabited by diverse civilisations including the Assyrians , Greeks , Thracians , Phrygians , Urartians , and Armenians . Hellenization started during the era of Alexander the Great and continued into the Byzantine era . The Seljuk Turks began migrating into the area in the 11th century , and their victory over the Byzantines at the Battle of Manzikert in 1071 symbolises the start and foundation of Turkey . The Seljuk Sultanate of Rûm ruled Anatolia until the Mongol invasion in 1243 , when it disintegrated into small principalities called beyliks . Beginning in the late 13th century , the Ottomans started uniting beyliks and conquering the Balkans . After Mehmed II conquered Constantinople in 1453 , Ottoman expansion continued under Selim I . During the reign of Suleiman the Magnificent the Ottoman Empire encompassed much of Southeast Europe , West Asia and North Africa and became a world power .
The Turkish Naval Forces ( Turkish : Türk Deniz Kuvvetleri ) , or Turkish Navy ( Turkish : Türk Donanması ) is the naval warfare service branch of the Turkish Armed Forces . The navy can trace its lineage back to the first Turkish fleets to sail the Aegean in the late 11th century , the fleets of the Anatolian beyliks in the 14th century , and , more immediately , to the Ottoman Navy . However , the modern naval traditions and customs of the Turkish Navy can be traced back to 10 July 1920 , when it was established as the Directorate of Naval Affairs during the Turkish War of Independence led by Mustafa Kemal Atatürk . Since July 1949 , the service has been officially known as the Turkish Naval Forces . In 2008 , the Turkish Navy had a reported active personnel strength of 48,600 ; this figure included an Amphibious Marines Brigade as well as several Special Forces and Commando detachments . As of early 2015 , the navy operates a wide variety of ships and 51 maritime aircraft .
