The Perry Expedition (Japanese: 黒船来航, kurofune raikō, "Arrival of the Black Ships") was a diplomatic and military expedition in two separate voyages (1852–1853 and 1854–1855) to the Tokugawa shogunate (徳川幕府) by warships of the United States Navy. The goals of this expedition included exploration, surveying, and the establishment of diplomatic relations and negotiation of trade agreements with the various nations in the region. Opening contact with the government of Japan was considered a top priority of the expedition, and was one of the key reasons for its inception.

The expedition was commanded by Commodore Matthew Calbraith Perry, under orders from President Millard Fillmore. Perry's primary goal was to force an end to Japan's 220-year-old policy of isolation and to open Japanese ports to American trade, through the use of gunboat diplomacy if necessary. The Perry Expedition led directly to the establishment of diplomatic relations between Japan and the western Great Powers, and eventually to the collapse of the ruling Tokugawa shogunate and the restoration of the Emperor. Following the expedition, Japan's burgeoning trade routes with the world led to the cultural trend of Japonisme, in which aspects of Japanese culture influenced art in Europe and America.

The United States Department of Defense (DoD), also referred to as the Department of War (DoW), is an executive department of the U.S. federal government charged with coordinating and supervising the U.S. Armed Forces—the Army, Navy, Marines, Air Force, Space Force, and, for some purposes, the Coast Guard—and related functions and agencies. Headquartered at the Pentagon in Arlington County, Virginia, just outside Washington, D.C., the stated mission of the Department of Defense is "to provide the military forces needed to deter war and ensure our nation's security".

The Department of Defense is headed by the secretary of defense, a cabinet-level head who reports directly to the president of the United States. The president is commander-in-chief of the U.S. armed forces. Beneath the Department of Defense are three subordinate military departments: the Department of the Army, the Department of the Navy, and the Department of the Air Force. In addition, four national intelligence services are subordinate to the Department of Defense: the Defense Intelligence Agency, National Security Agency (NSA), National Geospatial-Intelligence Agency, and National Reconnaissance Office.

Air warfare was a major component in all theaters of World War II and, together with anti-aircraft warfare, consumed a large fraction of the industrial output of the major powers. Germany and Japan depended on air forces that were closely integrated with land and naval forces; the Axis powers downplayed the advantage of fleets of strategic bombers and were late in appreciating the need to defend against Allied strategic bombing. By contrast, Britain and the United States took an approach that greatly emphasized strategic bombing and (to a lesser degree) tactical control of the battlefield by air as well as adequate air defenses. Both Britain and the U.S. built substantially larger strategic forces of large, long-range bombers. Simultaneously, they built tactical air forces that could win air superiority over the battlefields, thereby giving vital assistance to ground troops. The U.S. Navy and Royal Navy also built a powerful naval-air component based on aircraft carriers, as did the Imperial Japanese Navy; these played the central role in the war at sea.

The Battle of the Atlantic, the longest continuous military campaign in World War II, ran from 1939 to the defeat of Nazi Germany in 1945, covering a major part of the naval history of World War II. At its core was the Allied naval blockade of Germany, announced the day after the declaration of war, and Germany's subsequent counterblockade. The campaign peaked from mid-1940 to the end of 1943.

The Battle of the Atlantic pitted U-boats and other warships of the German Kriegsmarine (navy) and aircraft of the Luftwaffe (air force) against the Royal Navy, Royal Canadian Navy, United States Navy, and Allied merchant shipping. Convoys, coming mainly from North America and predominantly going to the United Kingdom and the Soviet Union, were protected for the most part by the British and Canadian navies and air forces. These forces were aided by ships and aircraft of the United States beginning on 13 September 1941. The Germans were joined by submarines of the Italian Regia Marina (royal navy) after Germany's Axis ally Italy entered the war on 10 June 1940.

The Bonin Islands, also known as the Ogasawara Islands (Japanese: 小笠原諸島), is a Japanese archipelago of over 30 subtropical and tropical islands located around 1,000 kilometers (620 mi) SSE of Tokyo and 1,600 kilometers (1,000 mi) northwest of Guam. The group as a whole has a total area of 84 square kilometers (32 sq mi) but only two of the islands are permanently inhabited, Chichijima and Hahajima. Together, their population was 2,560 as of 2021. Administratively, Tokyo's Ogasawara Subprefecture also includes the settlements on the Volcano Islands and the Self-Defense Force post on Iwo Jima. The seat of government is Chichijima.

Because of the Bonins' isolation, many of their animals and plants have undergone unique evolutionary processes. They have been referred to as the "Galápagos of the Orient" and were named a Natural World Heritage Site in 2011. When first reached during the early modern period, the islands were entirely uninhabited, although subsequent research has found evidence of some prehistoric habitation by Micronesians. Upon their repeated rediscoveries, the islands were largely ignored by the Spanish, Dutch, and isolationist Japanese until finally being claimed by a passing British captain in 1827. American, European, and Hawaiian colonists arrived from the Kingdom of Hawaii in 1830. Subsequently, Meiji Japan successfully colonized and reclaimed the islands in 1875, but Bonin Islanders' community continued up to World War II, when most islanders were forcibly relocated to Honshu. Following Japan's defeat, the U.S. Navy occupied the island, bulldozing existing Japanese homes and restricting resettlement until full control of the Bonins was returned to Japan in 1968. Ethnically, the island is now majority Japanese but remains unusually diverse, which is reflected in the local Creole language known as Bonin English. Improved transportation has made agriculture more profitable and encouraged tourism, but the development required for an airport remains a contentious local issue.

Command of the sea (also called control of the sea or sea control) is a naval military concept regarding the strength of a particular navy to a specific naval area it controls. A navy has command of the sea when it is so strong that its rivals cannot attack it directly. This dominance may apply to its surrounding waters (i.e., the littoral) or may extend far into the oceans, meaning the country has a blue-water navy. It is the naval equivalent of air supremacy.

With command of the sea, a country (or alliance) can ensure that its own military and merchant ships can move around at will, while its rivals are forced either to stay in port or to try to evade it. It also enables free use of amphibious operations that can expand ground-based strategic options. The British Royal Navy held command of the sea for most of the period between the 18th to the early 20th centuries, allowing Britain and its allies to trade and to move troops and supplies easily in wartime, while its enemies could not. In the post-World War II period, the United States Navy has had command of the sea.

Commodore was an early title and later a rank in the United States Navy, United States Coast Guard and also has been a rank in the United States Public Health Service Commissioned Corps and the National Oceanic and Atmospheric Administration Commissioned Officer Corps (NOAA Corps) and its ancestor organizations. For over two centuries, the designation has been given varying levels of authority and formality.

Today, it is no longer a specific rank within active-duty or reserve forces or in the Public Health Service Commissioned Corps or NOAA Corps, but it remains in use as an honorary title within the U.S. Navy and U.S. Coast Guard for those senior captains (pay grade O-6) in command of operational organizations composed of multiple independent subordinate naval units, e.g., multiple independent ships, submarines, or aviation squadrons.

Matthew Calbraith Perry (April 10, 1794 – March 4, 1858) was a United States Navy officer who commanded ships in several wars, including the War of 1812 and the Mexican–American War. He led the Perry Expedition that ended Japan's isolationism and signed the Convention of Kanagawa between Japan and the United States in 1854.

Perry was interested in the education of naval officers and assisted in the development of an apprentice system that helped establish the curriculum at the United States Naval Academy. With the advent of the steam engine, he became a leading advocate of modernizing the U.S. Navy and came to be considered "The Father of the Steam Navy" in the United States.

Industry City (also Bush Terminal) is a historic intermodal shipping, warehousing, and manufacturing complex on the Upper New York Bay waterfront in the Sunset Park neighborhood of Brooklyn, New York City. The northern portion, named "Industry City", hosts over 650 office, industrial, creative and manufacturing tenants across 6,000,000 square feet (560,000 m) of space between 32nd and 41st Streets, and is operated by a private consortium including Jamestown LP. The southern portion, known as "Bush Terminal", is located between 40th and 51st Streets and is operated by the New York City Economic Development Corporation (NYCEDC) as a garment manufacturing complex.

Founded by Bush Terminal Company head Irving T. Bush in the early 20th century, Bush Terminal was the first facility of its kind in New York City and the largest multi-tenant industrial property in the United States. The warehouses were built between 1892 and 1910, the railroad from 1896 to 1915, and the factory lofts between 1905 and 1925. During World War I, Bush Terminal was used as a United States Navy base, and returned to private ownership after the war. At its peak, Bush Terminal covered 200 acres (81 hectares), bounded by Gowanus Bay to the west and north, Third Avenue to the east, 27th Street to the north, and 50th Street to the south.

The United States Armed Forces are the military forces of the United States. U.S. federal law names six armed forces: the Army, Marine Corps, Navy, Air Force, Space Force, and Coast Guard. Since 1949, all of the armed forces, except the Coast Guard, have been permanently part of the United States Department of Defense, with the Space Force existing as a branch of the Air Force until 2019. They form six of the eight uniformed services of the United States.

From their inception during the American Revolutionary War, the Army and the Navy, and later the other services, have played a decisive role in the country's history. They helped forge a sense of national unity and identity through victories in the early-19th-century First and Second Barbary Wars. They played a critical role in the territorial evolution of the U.S., including the American Civil War. The National Security Act of 1947 created the Department of Defense or DoD, (after a short period being called the National Military Establishment) headed by the secretary of defense, superior to the service secretaries. It also created both the U.S. Air Force and National Security Council; in 1949, an amendment to the act merged the cabinet-level departments of the Army, Navy, and Air Force into the DoD.

The United States Marine Corps (USMC), also referred to as the United States Marines or simply the Marines, is the maritime land force service branch of the United States Armed Forces. It is responsible for conducting expeditionary and amphibious operations through combined arms, implementing its own infantry, artillery, aerial, and special operations forces. The U.S. Marine Corps is a part of the United States Department of Defense and is one of the six armed forces of the United States and one of the eight uniformed services of the United States.

The Marine Corps has been part of the United States Department of the Navy since 30 June 1834 with its sister service, the United States Navy. The USMC operates installations on land and aboard sea-going amphibious warfare ships around the world. Additionally, several of the Marines' tactical aviation squadrons, primarily Marine Fighter Attack squadrons, are also embedded in Navy carrier air wings and operate from the aircraft carriers.

The United States Coast Guard (USCG) is the maritime security, search and rescue, and law enforcement service branch of the United States Armed Forces. It is one of the country's eight uniformed services. The service is a maritime, military, multi-mission service unique among the United States military branches for having a maritime law enforcement mission with jurisdiction in both domestic and international waters and a federal regulatory agency mission as part of its duties. It is the largest coast guard in the world.

The U.S. Coast Guard protects the United States' borders and economic and security interests abroad; and defends its sovereignty by safeguarding sea lines of communication and commerce across U.S. territorial waters and its Exclusive Economic Zone. Due to ever-expanding risk imposed by transnational threats through the maritime and cyber domains, the U.S. Coast Guard is at any given time deployed to and operating on all seven continents and in cyberspace to enforce its mission. Like its United States Navy sibling, the U.S. Coast Guard maintains a global presence with permanently-assigned personnel throughout the world and forces routinely deploying to both littoral and blue-water regions. The U.S. Coast Guard's adaptive, multi-mission "white hull" fleet is leveraged as a force of both diplomatic soft power and humanitarian and security assistance over the more overtly confrontational nature of "gray hulled" warships. As a humanitarian service, it saves tens of thousands of lives a year at sea and in U.S. waters, and provides emergency response and disaster management for a wide range of human-made and natural catastrophic incidents in the U.S. and throughout the world.

The United States Department of the Navy (DON) is one of the three military departments within the United States Department of Defense. It was established by an Act of Congress on 30 April 1798, at the urging of Secretary of War James McHenry, to provide a government organizational structure to the United States Navy (USN). Since 1834, the department has exercised jurisdiction over the United States Marine Corps (USMC), and during wartime the United States Coast Guard (USCG). These branches remain at all times independent and coequal service branches within the DON. It is led by the secretary of the Navy (SECNAV), a statutory civilian officer.

The Department of the Navy was an executive department, whose secretary served on the president's cabinet, until 1949, when amendments to the National Security Act of 1947 established the Department of Defense as a unified department for all military services; the DON, along with the Department of the Army and Department of the Air Force, became a component of the DoD, subject to the authority, direction and control of the secretary of defense.

A military branch (also service branch or armed service) is a first level subdivision of the national armed forces of a state.

Fort Worth (sometimes abbreviated Ft. Worth) is a city in the U.S. state of Texas and the county seat of Tarrant County, covering nearly 350 square miles (910 km) into Denton, Johnson, Parker, and Wise counties. Fort Worth's population was estimated to be 1,008,156 in 2024, making it the 11th-most populous city in the United States. Fort Worth is the second-largest city in the Dallas–Fort Worth metroplex, after Dallas, and the fourth most populous in Texas. The Dallas–Fort Worth metroplex is the fourth-most populous metropolitan area in the United States.

The city of Fort Worth was established in 1849 as an army outpost on a bluff overlooking the Trinity River. Fort Worth has historically been a center of the Texas Longhorn cattle trade. It still embraces its Western heritage and traditional architecture and design. USS Fort Worth (LCS-3) is the first ship of the United States Navy named after the city. Nearby Dallas has held a population majority in the metropolitan area for as long as records have been kept, yet Fort Worth has become one of the fastest-growing cities in the United States.

The Colony of Fiji was a Crown colony that existed from 1874 to 1970 in the territory of the present-day nation of Fiji. London declined its first opportunity to annex Fiji in 1852. Ratu Seru Epenisa Cakobau had offered to cede the islands, subject to being allowed to retain his Tui Viti (King of Fiji) title. His demand was unacceptable to both the British and to many of his fellow chiefs, who regarded him only as first among equals, if that. Mounting debts and threats from the United States Navy had led Cakobau to establish a constitutional monarchy with a government dominated by European settlers in 1871, following an agreement with the Australian Polynesia Company to pay his debts. The collapse of the new regime drove him to make another offer of cession in 1872, which the British accepted. On 10 October 1874, Britain began its rule of Fiji, which lasted until 10 October 1970.

Energy security is the association between national security and the availability of natural resources for energy consumption (as opposed to household energy insecurity). Access to cheaper energy has become essential to the functioning of modern economies. However, the uneven distribution of energy supplies among countries has led to significant vulnerabilities. International energy relations have contributed to the globalization of the world leading to energy security and energy vulnerability at the same time.

Renewable resources and significant opportunities for energy efficiency and transitions exist over wide geographical areas, in contrast to other energy sources, which are concentrated in a limited number of countries. Rapid deployment of wind power and solar power and energy efficiency, and technological diversification of energy sources, would result in significant energy security.
