91-686: The South Shetland Islands are a group of Antarctic islands located in the Drake Passage with a total area of 3,687 km (1,424 sq mi). They lie about 120 kilometres (65 nautical miles) north of the Antarctic Peninsula , and between 430 and 900 km (230 and 485 nmi) southwest of the nearest point of the South Orkney Islands . By the Antarctic Treaty of 1959, the islands' sovereignty

182-520: A 14-month circumnavigation of the world. Ordered by President Theodore Roosevelt , it was a mission designed to demonstrate the Navy's capability to extend to the global theater. By 1911, the U.S. had begun building the super-dreadnoughts at a pace to eventually become competitive with Britain. The 1911 also saw the first naval aircraft with the navy which would lead to the informal establishment of United States Naval Flying Corps to protect shore bases. It

273-647: A change in their rating from their previous rating (i.e., MMCM) to CMDCM. The stars for Command Master Chief are silver, while stars for Fleet, and gold stars for Force. Additionally, CMCs wear a badge, worn on their left breast pocket, denoting their title (Command/Fleet/Force). Insignia and badges of the United States Navy are military "badges" issued by the Department of the Navy to naval service members who achieve certain qualifications and accomplishments while serving on both active and reserve duty in

364-466: A formidable force in the years prior to World War II , with battleship production being restarted in 1937, commencing with USS  North Carolina  (BB-55) . Though ultimately unsuccessful, Japan tried to neutralize this strategic threat with the surprise attack on Pearl Harbor on 7 December 1941. Following American entry into the war , the U.S. Navy grew tremendously as the United States

455-651: A frequent actor in American foreign and military policy. The United States Navy is part of the Department of the Navy , alongside the United States Marine Corps , which is its coequal sister service. The Department of the Navy is headed by the civilian secretary of the Navy . The Department of the Navy is itself a military department of the Department of Defense , which is headed by the secretary of defense . The chief of naval operations (CNO)

546-642: A major effect on naval planning is the Pivot to East Asia . In response, the Secretary of the Navy Ray Mabus stated in 2015 that 60 percent of the total U.S. fleet will be deployed to the Pacific by 2020. The Navy's most recent 30-year shipbuilding plan, published in 2016, calls for a future fleet of 350 ships to meet the challenges of an increasingly competitive international environment. A provision of

637-635: A national navy was debated in the Second Continental Congress . Supporters argued that a navy would protect shipping, defend the coast, and make it easier to seek support from foreign countries. Detractors countered that challenging the British Royal Navy , then the world's preeminent naval power, was a foolish undertaking. Commander in Chief George Washington resolved the debate when he commissioned

728-502: A navy able to reform those enemies to mankind or crush them into non-existence. Naval power . . . is the natural defense of the United States. The Navy was rooted in the colonial seafaring tradition, which produced a large community of sailors, captains, and shipbuilders. In the early stages of the American Revolutionary War , Massachusetts had its own Massachusetts Naval Militia . The rationale for establishing

819-643: A number of unique capabilities, including Military Sealift Command , Naval Expeditionary Combat Command , and Naval Information Forces . The United States Navy has seven active numbered fleets – Second , Third , Fifth , Sixth , Seventh and Tenth Fleets are each led by a vice admiral , and the Fourth Fleet is led by a rear admiral . These seven fleets are further grouped under Fleet Forces Command (the former Atlantic Fleet), Pacific Fleet, Naval Forces Europe-Africa, and Naval Forces Central Command, whose commander also doubles as Commander Fifth Fleet;

910-867: A quarter of whom are in ready reserve. Of those on active duty, more than eighty percent are enlisted sailors and around fifteen percent are commissioned officers ; the rest are midshipmen of the United States Naval Academy and midshipmen of the Naval Reserve Officer Training Corps at over 180 universities around the country and officer candidates at the Navy's Officer Candidate School . Enlisted sailors complete basic military training at boot camp and then are sent to complete training for their individual careers . Sailors prove they have mastered skills and deserve responsibilities by completing Personnel Qualification Standards (PQS) tasks and examinations. Among

1001-465: A senior non-commissioned officer in the other services, and must have a minimum 14 years in service. Sailors in pay grades E-1 through E-3 are considered to be in apprenticeships. They are divided into five definable groups, with colored group rate marks designating the group to which they belong: Seaman, Fireman, Airman, Constructionman, and Hospitalman. E-4 to E-6 are non-commissioned officers (NCOs), and are specifically called Petty officers in

1092-497: A service member may choose to further their career by becoming a Command Master Chief Petty Officer (CMC). A CMC is considered to be the senior-most enlisted service member within a command, and is the special assistant to the Commanding Officer in all matters pertaining to the health, welfare, job satisfaction, morale, use, advancement and training of the command's enlisted personnel. CMCs can be Command level (within

1183-404: A single unit, such as a ship or shore station), Fleet level (squadrons consisting of multiple operational units, headed by a flag officer or commodore), or Force level (consisting of a separate community within the Navy, such as Subsurface, Air, Reserves). CMC insignia are similar to the insignia for Master Chief, except that the rating symbol is replaced by an inverted five-point star, reflecting

1274-721: Is a distinct, separate service branch with its own uniformed service chief – the Commandant of the Marine Corps, a four-star general. The Marine Corps depends on the Navy for medical support (dentists, doctors , nurses, medical technicians known as corpsmen ) and religious support (chaplains). Thus, Navy officers and enlisted sailors fulfill these roles. When attached to Marine Corps units deployed to an operational environment they generally wear Marine camouflage uniforms, but otherwise, they wear Navy dress uniforms unless they opt to conform to Marine Corps grooming standards. In

1365-729: Is immediately under and reports to the Secretary of the Navy. At the same time, the Chief of Naval Operations is a member of the Joint Chiefs of Staff , which is the second-highest deliberative body of the armed forces after the United States National Security Council , although it plays only an advisory role to the President and does not nominally form part of the chain of command . The Secretary of

1456-716: Is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes. The islands have been claimed by the United Kingdom since 1908 and as part of the British Antarctic Territory since 1962. They are also claimed by the governments of Chile (since 1940, as part of the Antártica Chilena province), and by Argentina (since 1943, as part of Argentine Antarctica , Tierra del Fuego Province ). Several countries maintain research stations on

To recruit, train, equip, and organize to deliver combat ready Naval forces to win conflicts and wars while maintaining security and deterrence through sustained forward presence. The U.S. Navy is a seaborne branch of the military of the United States . The Navy's three primary areas of responsibility: U.S. Navy training manuals state that

1638-596: The 1966 Palomares B-52 crash incident and the subsequent search for missing hydrogen bombs, and Task Force 71 of the Seventh Fleet's operation in search for Korean Air Lines Flight 007 , shot down by the Soviets on 1 September 1983. The U.S. Navy continues to be a major support to U.S. interests in the 21st century. Since the end of the Cold War, it has shifted its focus from preparations for large-scale war with

1729-662: The American Civil War , in which the Union had a distinct advantage over the Confederacy on the seas. A Union blockade on all major ports shut down exports and the coastal trade, but blockade runners provided a thin lifeline. The Brown-water navy components of the U.S. navy control of the river systems made internal travel difficult for Confederates and easy for the Union. The war saw ironclad warships in combat for

1820-655: The Battle of Okinawa . By 1943, the navy's size was larger than the combined fleets of all the other combatant nations in World War II. By war's end in 1945, the U.S. Navy had added hundreds of new ships, including 18 aircraft carriers and 8 battleships, and had over 70% of the world's total numbers and total tonnage of naval vessels of 1,000 tons or greater. At its peak, the U.S. Navy was operating 6,768 ships on V-J Day in August 1945. Doctrine had significantly shifted by

1911-900: The Bureau of Naval Personnel , the Office of Naval Research , the Office of Naval Intelligence , the United States Naval Academy , the Naval Safety Command , the Naval Aviation Warfighting Development Center , and the United States Naval Observatory . Official Navy websites list the Office of the Chief of Naval Operations and the Chief of Naval Operations as part of the shore establishment, but these two entities effectively sit superior to

2002-759: The Continental Navy ) The United States Navy ( USN ) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States . It is the world's most powerful navy and the largest by tonnage, at 4.5 million tons in 2021 and in 2009 an estimated battle fleet tonnage that exceeded the next 13 navies combined. It has the world's largest aircraft carrier fleet, with 11 in service , one undergoing trials, two new carriers under construction, and six other carriers planned as of 2024. With 336,978 personnel on active duty and 101,583 in

2093-661: The Equator ; the Scottish Shetland Islands are 60°N, and warmed by the Gulf Stream , but the South Shetlands at 62°S are much colder. Seal hunting and whaling were conducted on the islands during the 19th and early 20th centuries. The sealing era lasted from 1820 to 1908 during which time 197 vessels are recorded as having visiting the islands. Twelve of those vessels were wrecked. Relics of

2184-611: The Falkland Islands by the American brig Hersilia , commanded by Captain James Sheffield (with second mate Nathaniel Palmer ), the first US sealer in the South Shetlands. The first wintering over in Antarctica took place on the South Shetlands, when at the end of the 1820–1821 summer season, 11 British men from the ship Lord Melville failed to leave King George Island, and survived the winter to be rescued at

2275-547: The Ready Reserve , the U.S. Navy is the third largest of the United States military service branches in terms of personnel. It has 299 deployable combat vessels and about 4,012 operational aircraft as of July 18, 2023. The United States Navy traces its origins to the Continental Navy , which was established during the American Revolutionary War and was effectively disbanded as a separate entity shortly thereafter. After suffering significant loss of goods and personnel at

2366-439: The limited duty officer (LDO) in the Navy. Warrant officers perform duties that are directly related to their previous enlisted service and specialized training. This allows the Navy to capitalize on the experience of warrant officers without having to frequently transition them to other duty assignments for advancement. Most Navy warrant officers are accessed from the chief petty officer pay grades, E-7 through E-9, analogous to

2457-567: The volcanic rock and tephra is of basalt or basaltic andesite . An exception is the tephra of Deception Island, which is of trachyte and basaltic trachyandesite , richer in potassium and sodium . Quaternary volcanic products of the islands tend to have less potassium and sodium at a given silica range, and lower Nb / Y ratios, than those associated with the Larsen Rift on the Antarctic Peninisula. The islands are

2548-418: The 2018 National Defense Authorization Act called for expanding the naval fleet to 355 ships "as soon as practicable", but did not establish additional funding nor a timeline. The U.S. Navy falls under the administration of the Department of the Navy , under civilian leadership of the Secretary of the Navy (SECNAV). The most senior naval officer is the Chief of Naval Operations (CNO), a four-star admiral who

2639-563: The Barbary pirates, blockaded the Barbary ports and executed attacks against the Barbary' fleets. The U.S. Navy saw substantial action in the War of 1812 , where it was victorious in eleven single-ship duels with the Royal Navy. It proved victorious in the Battle of Lake Erie and prevented the region from becoming a threat to American operations in the area. The result was a major victory for

2730-534: The Chief of Naval Operations, Admiral Elmo Zumwalt , authorized the Navy to celebrate its birthday on 13 October to honor the establishment of the Continental Navy in 1775. The United States was without a navy for nearly a decade, a state of affairs that exposed U.S. maritime merchant ships to a series of attacks by the Barbary pirates . The sole armed maritime presence between 1790 and the launching of

2821-563: The Coast Guard may be called upon to operate as a service within the Navy. At other times, Coast Guard Port Security Units are sent overseas to guard the security of ports and other assets. The Coast Guard also jointly staffs the Navy's naval coastal warfare groups and squadrons (the latter of which were known as harbor defense commands until late-2004), which oversee defense efforts in foreign littoral combat and inshore areas. The United States Navy has over 400,000 personnel, approximately

2912-795: The Mediterranean, where it participated in the Second Barbary War that ended piracy in the region, South America, Africa, and the Pacific. From 1819 to the outbreak of the Civil War, the Africa Squadron operated to suppress the slave trade , seizing 36 slave ships, although its contribution was smaller than that of the much larger British Royal Navy. After 1840 several secretaries of the navy were southerners who advocated for strengthening southern naval defenses, expanding

3003-734: The Navy and Chief of Naval Operations are responsible for organizing, recruiting, training, and equipping the Navy so that it is ready for operation under the commanders of the unified combatant commands . There are nine components in the operating forces of the U.S. Navy: the United States Fleet Forces Command (formerly United States Atlantic Fleet), United States Pacific Fleet , United States Naval Forces Central Command , United States Naval Forces Europe , Naval Network Warfare Command , Navy Reserve , United States Naval Special Warfare Command , and Operational Test and Evaluation Force . Fleet Forces Command controls

3094-461: The Navy reactivated the Fourth Fleet to control operations in the area controlled by Southern Command, which consists of US assets in and around Central and South America. Other number fleets were activated during World War II and later deactivated, renumbered, or merged. Shore establishments exist to support the mission of the fleet through the use of facilities on land. Among the commands of

3185-424: The Navy. Petty Officers perform not only the duties of their specific career field but also serve as leaders to junior enlisted personnel. E-7 to E-9 are still considered Petty Officers, but are considered a separate community within the Navy. They have separate berthing and dining facilities (where feasible), wear separate uniforms, and perform separate duties. After attaining the rate of Master Chief Petty Officer,

3276-584: The South Shetlands, or North or South American sealers might have visited the archipelago before Smith, historical evidence is insufficient to sustain such assertions. Smith's discovery, by contrast, was well documented and had wider historical implications beyond its geographic significance. Chilean scientists have claimed that Amerinds visited the islands, due to stone artifacts recovered from bottom-sampling operations in Admiralty Bay , King George Island , and Discovery Bay, Greenwich Island ; however,

3367-723: The Soviet Union to special operations and strike missions in regional conflicts. The navy participated in Operation Enduring Freedom , Operation Iraqi Freedom , and is a major participant in the ongoing War on Terror , largely in this capacity. Development continues on new ships and weapons, including the Gerald R. Ford -class aircraft carrier and the Littoral combat ship . Because of its size, weapons technology, and ability to project force far from U.S. shores,

3458-755: The U.S. Army at the Niagara Frontier of the war, and the defeat of the Native American allies of the British at the Battle of the Thames . Despite this, the U.S. Navy could not prevent the British from blockading its ports and landing troops. But after the War of 1812 ended in 1815, the U.S. Navy primarily focused its attention on protecting American shipping assets, sending squadrons to the Caribbean,

3549-469: The U.S. Navy and its decisive victory over the outdated Spanish Navy in 1898 brought a new respect for American technical quality. Rapid building of at first pre-dreadnoughts, then dreadnoughts brought the U.S. in line with the navies of countries such as Britain and Germany. In 1907, most of the Navy's battleships, with several support vessels, dubbed the Great White Fleet , were showcased in

3640-614: The U.S. Navy's first warships in 1797 was the U.S. Revenue-Marine , the primary predecessor of the U.S. Coast Guard . Although the United States Revenue Cutter Service conducted operations against the pirates, the pirates' depredations far outstripped its abilities and Congress passed the Naval Act of 1794 that established a permanent standing navy on 27 March 1794. The Naval Act ordered the construction and manning of six frigates and, by October 1797,

3822-525: The United States Navy grew under an ambitious ship building program associated with the Naval Act of 1916 . Naval construction, especially of battleships, was limited by the Washington Naval Conference of 1921–22, the first arms control conference in history. The aircraft carriers USS  Saratoga  (CV-3) and USS  Lexington  (CV-2) were built on the hulls of partially built battle cruisers that had been canceled by

3913-616: The United States agent in Valparaíso, Jeremy Robinson, informed the United States Secretary of State John Quincy Adams of Smith's discovery and Bransfield's forthcoming mission, and suggested dispatching a United States Navy ship to explore the islands, where "new sources of wealth, power, and happiness would be disclosed and science itself be benefited thereby". The discovery of the islands attracted British and American sealers. The first sealing ship to operate in

4004-594: The area was the brig Espirito Santo , chartered by British merchants in Buenos Aires . The ship arrived at Rugged Island off Livingston Island, where its British crew landed on Christmas Day 1819, and claimed the islands for King George III. A narrative of the events was published by the brig's master, Joseph Herring, in the July 1820 edition of the Imperial Magazine . The Espirito Santo was followed from

4095-581: The artifacts – two arrowheads – were later found to have been planted. In 1818, Juan Pedro de Aguirre obtained permission from the Buenos Aires authorities to establish a base for sealing on "some of the uninhabited islands near the South Pole". Captain William Smith in the British merchant brig Williams , while sailing to Valparaíso , Chile, in 1819, deviated from his route south of Cape Horn , and on 19 February 1819 sighted Williams Point ,

4186-597: The beginning of the next season. Having circumnavigated the Antarctic continent , the Russian Antarctic Expedition of Fabian von Bellingshausen and Mikhail Lazarev arrived at the South Shetlands in January 1821. The Russians surveyed the islands and named them, landing on both King George Island and Elephant Island . While sailing between Deception and Livingston Islands, Bellingshausen

4277-679: The burden of retaliating against the Japanese on the small number of aircraft carriers. During World War II some 4,000,000 Americans served in the United States Navy. The potential for armed conflict with the Soviet Union during the Cold War pushed the U.S. Navy to continue its technological advancement by developing new weapons systems, ships, and aircraft. U.S. naval strategy changed to that of forward deployment in support of U.S. allies with an emphasis on carrier battle groups. The navy

4368-419: The capture of California with large-scale land operations coordinated with the local militia organized in the California Battalion . The Navy conducted the U.S. military's first large-scale amphibious joint operation by successfully landing 12,000 army troops with their equipment in one day at Veracruz , Mexico. When larger guns were needed to bombard Veracruz, Navy volunteers landed large guns and manned them in

4459-411: The current U.S. Navy remains an asset for the United States. Moreover, it is the principal means through which the U.S. maintains international global order, namely by safeguarding global trade and protecting allied nations. In 2007, the U.S. Navy joined with the U.S. Marine Corps and U.S. Coast Guard to adopt a new maritime strategy called A Cooperative Strategy for 21st Century Seapower that raises

4550-464: The end of the war. The U.S. Navy had followed in the footsteps of the navies of Great Britain and Germany which favored concentrated groups of battleships as their main offensive naval weapons. The development of the aircraft carrier and its devastating use by the Japanese against the U.S. at Pearl Harbor, however, shifted U.S. thinking. The Pearl Harbor attack destroyed or took out of action a significant number of U.S. Navy battleships. This placed much of

4641-405: The face of the expiration of budget relief offered by the Bipartisan Budget Act of 2013 and CNO Jonathan Greenert said that a ten ship carrier fleet would not be able to sustainably support military requirements. The British First Sea Lord George Zambellas said that the USN had switched from "outcome-led to resource-led" planning. One significant change in U.S. policymaking that is having

4732-423: The first three commands being led by four-star admirals. The United States First Fleet existed after World War II from 1947, but it was redesignated the Third Fleet in early 1973. The Second Fleet was deactivated in September 2011 but reestablished in August 2018 amid heightened tensions with Russia. It is headquartered in Norfolk, Virginia, with responsibility over the East Coast and North Atlantic. In early 2008,

4823-436: The first three were brought into service: USS  United States , USS  Constellation , and USS  Constitution . Due to his strong posture on having a strong standing Navy during this period, John Adams is "often called the father of the American Navy". In 1798–99 the Navy was involved in an undeclared Quasi-War with France. From 1801 to 1805, in the First Barbary War , the U.S. Navy defended U.S. ships from

4914-424: The first time at the Battle of Hampton Roads in 1862, which pitted USS  Monitor against CSS  Virginia . For two decades after the war, however, the U.S. Navy's fleet was neglected and became technologically obsolete . A modernization program beginning in the 1880s when the first steel-hulled warships stimulated the American steel industry, and "the new steel navy" was born. This rapid expansion of

5005-426: The first uniform regulations for officers were issued in 1802 on the formation of the Navy Department. The predominant colors of U.S. Navy uniforms are navy blue and white. U.S. Navy uniforms were based on Royal Navy uniforms of the time and have tended to follow that template. Navy officers serve either as a line officer or as a staff corps officer . Line officers wear an embroidered gold star above their rank of

5096-405: The fleet has shrunk and that in the face of declining budgets in the future, the U.S. Navy must rely even more on international partnerships. In its 2013 budget request, the navy focused on retaining all eleven big deck carriers, at the expense of cutting numbers of smaller ships and delaying the SSBN replacement. By the next year the USN found itself unable to maintain eleven aircraft carriers in

5187-408: The fleet, and making naval technological improvements. During the Mexican–American War the U.S. Navy blockaded Mexican ports, capturing or burning the Mexican fleet in the Gulf of California and capturing all major cities in Baja California peninsula. In 1846–1848 the Navy successfully used the Pacific Squadron under Commodore Robert F. Stockton and its marines and blue-jackets to facilitate

5278-454: The hands of the Barbary pirates from Algiers , the United States Congress passed the Naval Act of 1794 for the construction of six heavy frigates , the first ships of the Navy. The United States Navy 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 Imperial Japan . The United States Navy emerged from World War II as

5369-455: The islands. Most of them are situated on King George Island , benefitting from the airfield of the Chilean base Eduardo Frei . Sixteen research stations are in different parts of the islands, with Chilean stations being the greatest in number. The islands were discovered by British mariner William Smith , in William , in 1819. Although Dutch mariner Dirck Gerritsz in 1599 or Spanish Admiral Gabriel de Castilla in 1603 might have sighted

5460-525: The largest or most notable islands in their respective group. A more detailed list of islands in a given group may be found on their respective pages, when applicable. Area data are from the USGS unless otherwise specified. This list does not include ice rises such as Berkner Island and Roosevelt Island . All these islands fall under the terms of the Antarctic Treaty . The list is not complete. Download coordinates as: United States Navy 13 October 1775 (249 years, 1 month) (as

5551-468: The mission of the U.S. Armed Forces is "to be prepared to conduct prompt and sustained combat operations in support of the national interest." The Navy's five enduring functions are: sea control , power projection , deterrence , maritime security , and sealift . It follows then as certain as that night succeeds the day, that without a decisive naval force we can do nothing definitive, and with it, everything honorable and glorious. Would to Heaven we had

5642-529: The most common ground since aircrews are guided in their use of aircraft by standard procedures outlined in a series of publications known as NATOPS manuals. The United States Coast Guard , in its peacetime role with the Department of Homeland Security , fulfills its law enforcement and rescue role in the maritime environment. It provides Law Enforcement Detachments (LEDETs) to Navy vessels, where they perform arrests and other law enforcement duties during naval boarding and interdiction missions. In times of war,

5733-411: The most important is the "warfare qualification", which denotes a journeyman level of capability in Surface Warfare, Aviation Warfare, Information Dominance Warfare, Naval Aircrew, Special Warfare, Seabee Warfare, Submarine Warfare or Expeditionary Warfare. Many qualifications are denoted on a sailor's uniform with U.S. Navy badges and insignia . The uniforms of the U.S. Navy have evolved gradually since

5824-409: The most powerful navy in the world. The modern United States Navy maintains a sizable global presence, deploying in strength in such areas as the Western Pacific , the Mediterranean , and the Indian Ocean. It is a blue-water navy with the ability to project force onto the littoral regions of the world, engage in forward deployments during peacetime and rapidly respond to regional crises, making it

Warrant and chief warrant officer ranks are held by technical specialists who direct specific activities essential to the proper operation of the ship, which also require commissioned officer authority. Navy warrant officers serve in 30 specialties covering five categories. Warrant officers should not be confused with

6006-520: The nearest point of the Antarctic continent, Graham Land . The South Shetlands consist of 11 major islands and several minor ones, totalling 3,687 km (1,424 sq mi) of land area. Between 80 and 90% of the land area is permanently glaciated . The highest point on the island chain is Mount Foster on Smith Island at 2,025 m (6,644 ft) above sea level at 2-meter spatial resolution. The South Shetland Islands extend about 500 km (270 nmi) from Smith Island and Low Island in

6097-412: The north coast of Livingston Island. The crew of San Telmo and the troops onboard, led by Brigadier Rosendo Porlier (a total of 644 men), are believed to be the first known humans to land in Antarctica. From December 1819 to January 1820, the islands were surveyed and mapped by Lieutenant Edward Bransfield on board the Williams , which had been chartered by the Royal Navy . On 15 November 1819,

6188-447: The northeast extremity of Livingston Island . Thus, Livingston Island became the first land ever discovered farther than 60° south. Smith revisited the South Shetlands, landed on King George Island on 16 October 1819, and claimed possession for Britain. Meanwhile, the Spanish Navy ship San Telmo sank in September 1819 whilst trying to go through the Drake Passage . Parts of her presumed wreckage were found months later by sealers on

6279-467: The notion of prevention of war to the same philosophical level as the conduct of war. The strategy was presented by the Chief of Naval Operations , the Commandant of the Marine Corps , and Commandant of the Coast Guard at the International Sea Power Symposium in Newport, Rhode Island on 17 October 2007. The strategy recognized the economic links of the global system and how any disruption due to regional crises (man-made or natural) can adversely impact

6370-410: The number two official in the Navy Department during World War I, appreciated the Navy and gave it strong support. In return, senior leaders were eager for innovation and experimented with new technologies, such as magnetic torpedoes, and developed a strategy called War Plan Orange for victory in the Pacific in a hypothetical war with Japan that would eventually become reality. The U.S. Navy grew into

6461-411: The ocean-going schooner USS Hannah to interdict British merchantmen and reported the captures to the Congress. On 13 October 1775, the Continental Congress authorized the purchase of two vessels to be armed for a cruise against British merchantmen; this resolution created the Continental Navy and is considered the first establishment of the U.S. Navy. The Continental Navy achieved mixed results; it

6552-427: The operational environment, as an expeditionary force specializing in amphibious operations, Marines often embark on Navy ships to conduct operations from beyond territorial waters. Marine units deploying as part of a Marine Air-Ground Task Force (MAGTF) operate under the command of the existing Marine chain of command. Although Marine units routinely operate from amphibious assault ships, the relationship has evolved over

6643-451: The other organizations, playing a coordinating role. In 1834, the United States Marine Corps came under the Department of the Navy. Historically, the Navy has had a unique relationship with the USMC, partly because they both specialize in seaborne operations. Together the Navy and Marine Corps form the Department of the Navy and report to the Secretary of the Navy. However, the Marine Corps

6734-698: The same distance from the Equator as the Faroe Islands in the North Atlantic , but their proximity to Antarctica means that they have a much colder climate. The sea around the islands is closed by ice from early April to early December, and the monthly average temperature is below 0 °C (32 °F) for eight months of the year (April to November). The islands have experienced measurable glacier retreat during recent years, but despite this, they remain more than 80% snow- and ice-covered throughout

6825-509: The sealing era include iron try pots, hut ruins, and inscriptions. Beginning in 1908, the islands were governed as part of the Falkland Islands Dependency , but they have only been permanently occupied by humans since the establishment of a scientific research station in 1944. The archipelago, together with the nearby Antarctic Peninsula and South Georgia Island , is an increasingly popular tourist destination during

6916-663: The senior command meant that naval forces were not contributed until late 1917. Battleship Division Nine was dispatched to Britain and served as the Sixth Battle Squadron of the British Grand Fleet. Its presence allowed the British to decommission some older ships and reuse the crews on smaller vessels. Destroyers and U.S. Naval Air Force units like the Northern Bombing Group contributed to the anti-submarine operations. The strength of

7007-1052: The shore establishment, as of April 2011 , are the Naval Education and Training Command , the Navy Installations Command , the Naval Meteorology and Oceanography Command , the Naval Information Warfare Systems Command , the Naval Facilities Engineering Command , the Naval Supply Systems Command , the Naval Air Systems Command , the Naval Sea Systems Command , the Bureau of Medicine and Surgery ,

7098-671: The south. Despite the harsh conditions, the islands do support vegetation and are part of the Scotia Sea Islands tundra ecoregion , along with South Georgia and the South Sandwich Islands , the South Orkney Islands , and Bouvet Island . All of these islands lie in the cold seas below the Antarctic Convergence . These areas support tundra vegetation consisting of mosses , lichens , and algae , while seabirds, penguins , and seals feed in

7189-544: The southern summer. As a group of islands, the South Shetland Islands are located at 62°0′S 58°0′W  /  62.000°S 58.000°W  / -62.000; -58.000 . They are within the region 61° 00'–63° 37' South, 53° 83'–62° 83' West. The islands lie 940 km (510 nmi) south of the Falkland Islands , and between 93 km (50 nmi) ( Deception Island ) and 269 km (145 nmi) ( Clarence Island ) northwest and north from

7280-588: The successful bombardment and capture of the city. This successful landing and capture of Veracruz opened the way for the capture of Mexico City and the end of the war. The U.S. Navy established itself as a player in United States foreign policy through the actions of Commodore Matthew C. Perry in Japan, which resulted in the Convention of Kanagawa in 1854. Naval power played a significant role during

7371-491: The summer. The climate is cloudy and humid all year round, and very strong westerly winds blow at all seasons. Some of the sunniest weather is associated with outbreaks of very cold weather from the south in late winter and spring. Mean summer temperatures are only about 1.5 °C (34.7 °F) and those in winter are about −5 °C (23 °F). The effect of the ocean tends to keep summer temperatures low and prevent winter temperatures from falling as low as they do inland to

7462-539: The surrounding waters. From north to south, the main and some minor islands of the South Shetlands are: The Russian names above are historical, and no longer the official Russian names. (See the end of the article for a complete list of islands.) Several nations maintain research stations on the Islands: List of Antarctic and subantarctic islands This is a list of Antarctic and sub-Antarctic islands . The following list of island groups contains

7553-482: The treaty. The New Deal used Public Works Administration funds to build warships, such as USS  Yorktown  (CV-5) and USS  Enterprise  (CV-6) . By 1936, with the completion of USS  Wasp  (CV-7) , the U.S. Navy possessed a carrier fleet of 165,000 tonnes displacement , although this figure was nominally recorded as 135,000 tonnes to comply with treaty limitations. Franklin Roosevelt ,

7644-547: The west-southwest to Elephant Island and Clarence Island in the east-northeast. Various volcanoes with activity in the Quaternary exist in the islands. These volcanoes are associated with the tectonics of Bransfield Rift . From west to east, the known volcanoes are Sail Rock, Deception Island, Rezen Knoll , Gleaner Heights , Edinburgh Hill , Inott Point, Penguin Island , Melville Peak , and Bridgeman Island . Most of

7735-604: The years much as the Commander of the Carrier Air Group/Wing (CAG) does not work for the carrier commanding officer, but coordinates with the ship's CO and staff. Some Marine aviation squadrons, usually fixed-wing assigned to carrier air wings train and operate alongside Navy squadrons; they fly similar missions and often fly sorties together under the cognizance of the CAG. Aviation is where the Navy and Marines share

7826-588: Was a major participant in the Korean and Vietnam Wars , blockaded Cuba during the Cuban Missile Crisis , and, through the use of ballistic missile submarines , became an important aspect of the United States' nuclear strategic deterrence policy. The U.S. Navy conducted various combat operations in the Persian Gulf against Iran in 1987 and 1988, most notably Operation Praying Mantis . The Navy

7917-493: Was extensively involved in Operation Urgent Fury , Operation Desert Shield , Operation Desert Storm , Operation Deliberate Force , Operation Allied Force , Operation Desert Fox and Operation Southern Watch . The U.S. Navy has also been involved in search and rescue/search and salvage operations, sometimes in conjunction with vessels of other countries as well as with U.S. Coast Guard ships. Two examples are

8008-714: Was faced with a two-front war on the seas. It achieved notable acclaim in the Pacific Theater , where it was instrumental to the Allies' successful " island hopping " campaign. The U.S. Navy participated in many significant battles, including the Battle of the Coral Sea , the Battle of Midway , the Solomon Islands Campaign , the Battle of the Philippine Sea , the Battle of Leyte Gulf , and

8099-727: Was not until 1921 US naval aviation truly commenced. During World War I , the U.S. Navy spent much of its resources protecting and shipping hundreds of thousands of soldiers and marines of the American Expeditionary Force and war supplies across the Atlantic in U-boat infested waters with the Cruiser and Transport Force . It also concentrated on laying the North Sea Mine Barrage . Hesitation by

8190-471: Was successful in a number of engagements and raided many British merchant vessels, but it lost twenty-four of its vessels and at one point was reduced to two in active service. In August 1785, after the Revolutionary War had drawn to a close, Congress had sold Alliance , the last ship remaining in the Continental Navy due to a lack of funds to maintain the ship or support a navy. In 1972,

8281-524: Was visited by Nathaniel Palmer , master of the American brig Hero , who informed him of the activities of dozens of American and British sealing ships in the area. The name "New South Britain" was used briefly, but was soon changed to South Shetland Islands (in reference to the Shetland Islands in the north of Scotland ). The name South Shetland Islands is now established in international usage. The two island groups lie at similar distances from
