Destroyer escort

In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or battle group and defend them against powerful short-range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish Navy as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War.

The capital ships of a navy are its most important warships; they are generally the larger ships when compared to other warships in their respective fleet. A capital ship is generally a leading or a primary ship in a naval fleet.

An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Carriers have evolved since their inception in the early twentieth century from wooden vessels used to deploy balloons to nuclear-powered warships that carry numerous fighters, strike aircraft, helicopters, and other types of aircraft. While heavier aircraft such as fixed-wing gunships and bombers have been launched from aircraft carriers, these aircraft have not landed on a carrier. By its diplomatic and tactical power, its mobility, its autonomy and the variety of its means, the aircraft carrier is often the centerpiece of modern combat fleets. Tactically or even strategically, it replaced the battleship in the role of flagship of a fleet. One of its great advantages is that, by sailing in international waters, it does not interfere with any territorial sovereignty and thus obviates the need for overflight authorizations from third-party countries, reduces the times and transit distances of aircraft and therefore significantly increase the time of availability on the combat zone.

A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several roles.

The knot is a unit of speed equal to one nautical mile per hour, exactly 1.852 km/h. The ISO standard symbol for the knot is kn. The same symbol is preferred by the Institute of Electrical and Electronics Engineers (IEEE), while kt is also common, especially in aviation, where it is the form recommended by the International Civil Aviation Organization (ICAO). The knot is a non-SI unit. The knot is used in meteorology, and in maritime and air navigation. A vessel travelling at 1 knot along a meridian travels approximately one minute of geographic latitude in one hour.

The Hedgehog was a forward-throwing anti-submarine weapon that was used primarily during the Second World War. The device, which was developed by the Royal Navy, fired up to 24 spigot mortars ahead of a ship when attacking a U-boat. It was deployed on convoy escort warships such as destroyers and corvettes to supplement the depth charges.

Latin America is a cultural concept denoting the Americas where Romance languages—languages derived from Latin—are predominantly spoken. The term was coined in the nineteenth century, to refer to regions in the Americas that were ruled by the Spanish, Portuguese and French empires. The term does not have a precise definition, but it is "commonly used to describe South America, Central America, Mexico, and the islands of the Caribbean." In a narrow sense, it refers to Spanish America and Brazil. The term "Latin America" is broader than categories such as Hispanic America, which specifically refers to Spanish-speaking countries; and Ibero-America, a term not generally used that specifically refers to both Spanish and Portuguese-speaking countries while leaving French and British excolonies aside.

The Edsall-class destroyer escorts were destroyer escorts built primarily for ocean antisubmarine escort service during World War II. The lead ship, USS Edsall, was commissioned on 10 April 1943 at Orange, Texas. The class was also known as the FMR type from their Fairbanks-Morse reduction-geared diesel drive, with a type of engine used in the submarines of the time. The FMR's substitution for a diesel-electric power plant was the essential difference from the predecessor Cannon ("DET") class. This was the only World War II destroyer escort class in which all the ships originally ordered were completed as United States Navy destroyer escorts. Destroyer escorts were regular companions escorting the vulnerable cargo ships. Late in the war, plans were made to replace the 3-inch (76 mm) guns with 5-inch (127 mm) guns, but only Camp was refitted. In total, all 85 were completed by two shipbuilding companies: Consolidated Steel Corporation, Orange, Texas (47), and Brown Shipbuilding, Houston, Texas (38). Most were en route to the Pacific Theater when Japan surrendered. One of the ships participated in Operation Dragoon and two were attacked by German guided missiles.

The John C. Butler class were destroyer escorts that originated during World War II. The lead ship was USS John C. Butler, commissioned on 31 March 1944. The class was also known as the WGT type from their Westinghouse geared turbine drive. Of the 293 ships originally planned, 206 were canceled in 1944 and a further four after being laid down; three were not completed until after the end of World War II.

The Distant Early Warning Line, also known as the DEW Line or Early Warning Line, was a system of radar stations in the northern Arctic region of Canada, with additional stations along the north coast and Aleutian Islands of Alaska, in addition to the Faroe Islands, Greenland, and Iceland. It was set up to detect incoming bombers of the Soviet Union during the Cold War, and provide early warning of any sea-and-land invasion.

The Guardian-class radar picket ships were a class of ocean radar picket ships, converted 1954–1958 from World War II Liberty ships acquired by the U.S. Navy. Their task was to act as part of the radar defenses of the United States in the Cold War, serving until 1965.

Liberty ships were a class of cargo ship built in the United States during World War II under the Emergency Shipbuilding Program. Though British in concept, the design was adopted by the United States for its simple, low-cost construction. Mass-produced on an unprecedented scale, the Liberty ship came to symbolize U.S. wartime industrial output.

The American Bureau of Shipping (ABS) is an American maritime classification society established in 1862. Its stated mission to promote the security of life, property, and the natural environment, primarily through the development and verification of standards for the design, construction and operational maintenance of marine and offshore assets.

The Captain class was the designation given to 78 frigates of the Royal Navy, constructed in the United States, launched in 1942–1943 and delivered to the United Kingdom under the provisions of the Lend-Lease agreement. They were drawn from two classes of the American destroyer escort classification: 32 of the GMT (Evarts) Type and 46 of the TE (Buckley) Type. Upon reaching the UK the ships were substantially modified by the Royal Navy, making them distinct from the US Navy destroyer escort ships.

The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service.

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 largest and most powerful navy in the world, with the estimated tonnage of its active battle fleet alone exceeding the next 13 navies combined, including 11 allies or partner nations of the United States as of 2015. It has the highest combined battle fleet tonnage and the world's largest aircraft carrier fleet, with eleven in service, two new carriers under construction, and five other carriers planned. With 336,978 personnel on active duty and 101,583 in the Ready Reserve, the United States Navy is the third largest of the United States military service branches in terms of personnel. It has 290 deployable combat vessels and more than 2,623 operational aircraft as of June 2019.

This is a list of destroyer escorts of the United States Navy, listed in a table sortable by both name and hull-number. It includes the hull classification symbols DE, DEG, and DER.

Ocean escort was a type of United States Navy warship. They were an evolution of the World War II destroyer escort types. The ocean escorts were intended as convoy escorts and were designed for mobilization production in wartime or low-cost mass production in peacetime. They were commissioned from 1954 through 1974, serving in the Cold War and the Vietnam War.

The North Atlantic Treaty Organization, also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implemented the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is animus in consulendo liber.

The United States Navy reclassified many of its surface vessels in 1975, changing terminology and hull classification symbols for cruisers, frigates, and ocean escorts.

A frigate is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat.

The littoral combat ship (LCS) is either of two classes of relatively small surface vessels designed for operations near shore by the United States Navy. It was "envisioned to be a networked, agile, stealthy surface combatant capable of defeating anti-access and asymmetric threats in the littorals". Littoral combat ships are comparable to corvettes found in other navies.

The Ticonderoga class of guided-missile cruisers is a class of warships in the United States Navy, first ordered and authorized in the 1978 fiscal year. The class uses passive phased-array radar and was originally planned as a class of destroyers. However, the increased combat capability offered by the Aegis Combat System and the AN/SPY-1 radar system, together with the capability of operating as a flagship, were used to justify the change of the classification from DDG to CG shortly before the keels were laid down for Ticonderoga and Yorktown.

A cruiser is a type of warship. Modern cruisers are generally the largest ships in a fleet after aircraft carriers and amphibious assault ships, and can usually perform several roles.

The Spruance-class destroyer was developed by the United States to replace the many World War II–built Allen M. Sumner- and Gearing-class destroyers, and was the primary destroyer built for the U.S. Navy during the 1970s and 1980s. It was named in honor of United States Navy Admiral Raymond A. Spruance, who successfully led major naval battles in the Asiatic-Pacific Theater during World War II such as the Battle of Midway and the Battle of the Philippine Sea.

The Evarts-class destroyer escorts were destroyer escorts launched in the United States in 1942–44. They served in World War II as convoy escorts and anti-submarine warfare ships. They were also known as the GMT or "short hull" DE class, with GMT standing for General Motors Tandem Diesel drive.

The 3"/50 caliber gun in United States naval gun terminology indicates the gun fired a projectile 3 inches (76 mm) in diameter, and the barrel was 50 calibers long. Different guns of this caliber were used by the U.S. Navy and U.S. Coast Guard from 1900 through to 1990 on a variety of combatant and transport ship classes.

The Buckley-class destroyer escorts were 102 destroyer escorts launched in the United States in 1943–44. They served in World War II as convoy escorts and antisubmarine warfare ships. The lead ship was USS Buckley which was launched on 9 January 1943. The ships had General Electric steam turbo-electric transmission. The ships were prefabricated at various factories in the United States, and the units brought together in the shipyards, where they were welded together on the slipways.

The Cannon class was a class of destroyer escorts built by the United States primarily for antisubmarine warfare and convoy escort service during World War II. The lead ship, USS Cannon, was commissioned on 26 September 1943 at Wilmington, Delaware. Of the 116 ships ordered, 44 were cancelled and six were commissioned directly into the Free French Forces. Destroyer escorts were regular companions escorting vulnerable cargo ships.

The Edsall-class destroyer escorts were destroyer escorts built primarily for ocean antisubmarine escort service during World War II. The lead ship, USS Edsall, was commissioned on 10 April 1943 at Orange, Texas. The class was also known as the FMR type from their Fairbanks-Morse reduction-geared diesel drive, with a type of engine used in the submarines of the time. The FMR's substitution for a diesel-electric power plant was the essential difference from the predecessor Cannon ("DET") class. This was the only World War II destroyer escort class in which all the ships originally ordered were completed as United States Navy destroyer escorts. Destroyer escorts were regular companions escorting the vulnerable cargo ships. Late in the war, plans were made to replace the 3-inch (76 mm) guns with 5-inch (127 mm) guns, but only Camp was refitted. In total, all 85 were completed by two shipbuilding companies: Consolidated Steel Corporation, Orange, Texas (47), and Brown Shipbuilding, Houston, Texas (38). Most were en route to the Pacific Theater when Japan surrendered. One of the ships participated in Operation Dragoon and two were attacked by German guided missiles.

The Rudderow-class destroyer escorts were destroyer escorts launched in the United States in 1943 to 1945. Of this class, 22 were completed as destroyer escorts, and 50 were completed as Crosley-class high speed transports and were re-classified as high speed transport APDs. One ship was converted to an APD after completion. They served in World War II as convoy escorts and anti-submarine warfare ships.

The Mark 12 5"/38 caliber gun was a United States dual-purpose naval gun, but also installed in single-purpose mounts on a handful of ships. The 38 caliber barrel was a mid-length compromise between the previous United States standard 5"/51 low-angle gun and 5"/25 anti-aircraft gun. United States naval gun terminology indicates the gun fired a projectile 5 inches (127 mm) in diameter, and the barrel was 38 calibers long. The increased barrel length provided greatly improved performance in both anti-aircraft and anti-surface roles compared to the 5"/25 gun. However, except for the barrel length and the use of semi-fixed ammunition, the 5"/38 gun was derived from the 5"/25 gun. Both weapons had power ramming, which enabled rapid fire at high angles against aircraft. The 5"/38 entered service on USS Farragut, commissioned in 1934, the first new destroyer design since the last Clemson was built in 1922. The base ring mount, which improved the effective rate of fire, entered service on USS Porter, commissioned in 1936.

The John C. Butler class were destroyer escorts that originated during World War II. The lead ship was USS John C. Butler, commissioned on 31 March 1944. The class was also known as the WGT type from their Westinghouse geared turbine drive. Of the 293 ships originally planned, 206 were canceled in 1944 and a further four after being laid down; three were not completed until after the end of World War II.

The Dealey-class destroyer escorts were the first post-World War II escort ships built for the United States Navy.

The Claud Jones-class destroyer escorts were four destroyer escorts built for the United States Navy in the late 1950s. These ships were a diesel-powered version of the earlier Dealey class and were designed with the aim of producing a cheaper ship suitable for rapid production in wartime. These ships also had reduced armament and speed compared to their predecessors. They were not seen as effective anti-submarine warfare vessels by the United States Navy and were sold after only 15 years service to the Indonesian Navy.

The Bronstein-class frigates were United States Navy warships, originally laid down as ocean escorts, but were all redesignated as frigates on 30 June 1975 in the United States Navy 1975 ship reclassification and their hull designation changed from DE to FF.

The RUR-5 ASROC is an all-weather, all sea-conditions anti-submarine missile system. Developed by the United States Navy in the 1950s, it was deployed in the 1960s, updated in the 1990s, and eventually installed on over 200 USN surface ships, specifically cruisers, destroyers, and frigates. The ASROC has been deployed on scores of warships of many other navies, including Canada, Germany, Italy, Japan, the Republic of China, Greece, Pakistan and others.

Crosley-class high speed transports were high speed transport ships that served in the United States Navy during World War II. Some stayed in commission long enough to serve in the Korean War and the Vietnam War. All of them were converted from Rudderow-class destroyer escorts during construction except for USS Bray (APD-139), which was converted a year after her construction. After World War II ended, several of the ships were sold to Mexico, South Korea, Taiwan, and Colombia.

Fore River Shipyard was a shipyard owned by General Dynamics Corporation located on Weymouth Fore River in Braintree and Quincy, Massachusetts. It began operations in 1883 in Braintree, and moved to its final location on Quincy Point in 1901. In 1913, it was purchased by Bethlehem Steel, and later transferred to Bethlehem Shipbuilding Corporation. It was sold to General Dynamics in 1963, and closed in 1986. During its operation, yardworkers constructed hundreds of ships, for both military and civilian clients.

The Bethlehem Hingham Shipyard of Hingham, Massachusetts, was a shipyard in the United States from 1941 until 1945. Located on Weymouth Back River, it was owned by the Bethlehem Shipbuilding Company and operated by the nearby Fore River Shipyard. During the three and a half years that the yard was operational, it produced 277 ships, including a destroyer escort delivered in 23 days.

Union Iron Works, located in San Francisco, California, on the southeast waterfront, was a central business within the large industrial zone of Potrero Point, for four decades at the end of the nineteenth and beginning of the twentieth centuries.

The Boston Navy Yard, originally called the Charlestown Navy Yard and later Boston Naval Shipyard, was one of the oldest shipbuilding facilities in the United States Navy. It was established in 1801 as part of the recent establishment of the new U.S. Department of the Navy in 1798. After 175 years of military service, it was decommissioned as a naval installation on 1 July 1974.

The Brown Shipbuilding Company was founded in Houston, Texas, in 1942 as a subsidiary of Brown and Root by brothers Herman and George R. Brown to build ships for the U.S. Navy during World War II. Brown Shipbuilding Company ranked 68th among United States corporations in the value of World War II military production contracts.

The Federal Shipbuilding and Drydock Company was a United States shipyard in New Jersey active from 1917 to 1948. It was founded during World War I to build ships for the United States Shipping Board. Unlike many shipyards, it remained active during the shipbuilding slump of the 1920s and early 1930s that followed the World War I boom years. During World War II, it built merchant ships as part of the U.S. Government's Emergency Shipbuilding program, at the same time producing more destroyers for the United States Navy than any yard other than the Bath Iron Works. Operated by a subsidiary of the United States Steel Corporation, the shipyard was located at Kearny Point where the mouth of the Hackensack River meets Newark Bay in the Port of New York and New Jersey.

The Philadelphia Naval Shipyard was an important naval shipyard of the United States for almost two centuries.

The Normandy landings were the landing operations and associated airborne operations on Tuesday, 6 June 1944 of the Allied invasion of Normandy in Operation Overlord during World War II. Codenamed Operation Neptune and often referred to as D-Day, it was the largest seaborne invasion in history. The operation began the liberation of France and laid the foundations of the Allied victory on the Western Front.

The Captain class was the designation given to 78 frigates of the Royal Navy, constructed in the United States, launched in 1942–1943 and delivered to the United Kingdom under the provisions of the Lend-Lease agreement. They were drawn from two classes of the American destroyer escort classification: 32 of the GMT (Evarts) Type and 46 of the TE (Buckley) Type. Upon reaching the UK the ships were substantially modified by the Royal Navy, making them distinct from the US Navy destroyer escort ships.

The Allies, formally referred to as the United Nations from 1942, were an international military coalition formed during the Second World War (1939–1945) to oppose the Axis powers, led by Nazi Germany, Imperial Japan, and Fascist Italy. Its principal members by the end of 1941 were the United Kingdom, United States, Soviet Union, and China.

A convoy is a group of vehicles, typically motor vehicles or ships, traveling together for mutual support and protection. Often, a convoy is organized with armed defensive support and can help maintain cohesion within a unit. It may also be used in a non-military sense, for example when driving through remote areas.

The Mutual Defense Assistance Act was a United States Act of Congress signed by President Harry S. Truman on 6 October 1949. For US Foreign policy, it was the first U.S. military foreign aid legislation of the Cold War era, and initially to Europe. The Act followed Truman's signing of the Economic Cooperation Act, on April 3, 1948, which provided non-military, economic reconstruction and development aid to Europe.

USS Ebert (DE-768) was a Cannon-class destroyer escort in service with the United States Navy from 1944 to 1946. In 1951, she was transferred to Greece, where she served as Ierax (D31) until 1991. She was finally sunk as a target in 2002.

USS Sutton (DE-771) was a Cannon-class destroyer escort in service with the United States Navy from 1943 to 1948. In 1956, she was transferred to South Korea, where she served as Kang Won (F-72) until 1977. The ship was then cannibalized for spare parts in the Philippines.

USS Camp (DE-251) was an Edsall-class destroyer escort built for the U.S. Navy during World War II. She served in the Atlantic Ocean the Pacific Ocean and provided destroyer escort protection against submarine and air attack for Navy vessels and convoys.

USS Burrows (DE-105) was a Cannon-class destroyer escort built for the U.S. Navy during World War II. She served in both the Atlantic Ocean and the Pacific Ocean, and provided escort service against submarine and air attack for Navy vessels and convoys.

The Etorofu-class escort ships were a group of fourteen kaibōkan escort vessels built for the Imperial Japanese Navy during World War II. Eight of the fourteen ships were sunk during the war. The class was also referred to by internal Japanese documents as the "Modified A-class" coastal defense vessel .

The Mikura-class escort ships were a class of eight kaibōkan escort vessels built for the Imperial Japanese Navy during World War II. Five of the eight ships were sunk during the war. The class was also referred to by internal Japanese documents as the "B-class" coastal defense vessel .

The Loch class was a class of anti-submarine (A/S) frigate built for the Royal Navy and her Allies during World War II. They were an innovative design based on the experience of three years of fighting in the Battle of the Atlantic and attendant technological advances. Some shipyards had trouble building these larger ships, which led to widespread use of the Castle-class corvette, introduced around the same time.

The Bay class was a class of 26 anti-aircraft (A/A) frigates built for the Royal Navy under the 1943 War Emergency Programme during World War II. They were based on the hulls of incomplete Loch class anti-submarine (A/S) frigates.

The Le Corse class was a class of 4 fast frigates built for the French Navy in the early 1950s. They were first surface combatant class of ships to be built after World War II and symbolized "the revival of the French fleet." They were followed by the Le Normand-class frigates, and like them, were long-range convoy escorts capable of high speed.

The Type 14 Blackwood class were a ship class of minimal "second-rate" anti-submarine warfare frigates. Built for the Royal Navy during the 1950s at a time of increasing threat from the Soviet Union's submarine fleet, they served until the late 1970s. Twelve ships of this class served with the Royal Navy and a further three were built for the Indian Navy.

The Ikazuchi-class destroyer escort was a destroyer escort class built for the Coastal Safety Force in the late 1950s.

The Le Normand class was a class of 14 fast frigates built for the French Navy in the late 1950s. They were an immediate follow-on from the earlier Le Corse-class frigates, and like them, were long-range convoy escorts capable of high speed. The first seven ships, paid for by the United States under the Mutual Defense Assistance Act were ordered in 1952. The remaining seven ships were paid for by France and ordered between 1953 and 1955.

The Almirante Clemente class of destroyer escorts is a class of warships built for several countries. The class was designed by Ansaldo for the Venezuelan Naval Forces, currently Venezuelan Navy, in the 1950s to complement its Nueva Esparta-class destroyer.

The Type 41 or Leopard class were a class of anti-aircraft defence frigates built for the Royal Navy and Indian Navy in the 1950s. The Type 41, together with the Type 61 variant introduced diesel propulsion into the Royal Navy, the perceived benefits being long range, low fuel use, reduced crew, and reduced complexity.

The Restigouche-class destroyer was a class of seven destroyer escorts that served the Royal Canadian Navy and later the Canadian Forces from the late-1950s to the late-1990s. All seven vessels in the class were named after rivers in Canada.

The ships of the F120 Köln class of frigates were the first major warships built in Germany after World War II.

The Edsall-class destroyer escorts were destroyer escorts built primarily for ocean antisubmarine escort service during World War II. The lead ship, USS Edsall, was commissioned on 10 April 1943 at Orange, Texas. The class was also known as the FMR type from their Fairbanks-Morse reduction-geared diesel drive, with a type of engine used in the submarines of the time. The FMR's substitution for a diesel-electric power plant was the essential difference from the predecessor Cannon ("DET") class. This was the only World War II destroyer escort class in which all the ships originally ordered were completed as United States Navy destroyer escorts. Destroyer escorts were regular companions escorting the vulnerable cargo ships. Late in the war, plans were made to replace the 3-inch (76 mm) guns with 5-inch (127 mm) guns, but only Camp was refitted. In total, all 85 were completed by two shipbuilding companies: Consolidated Steel Corporation, Orange, Texas (47), and Brown Shipbuilding, Houston, Texas (38). Most were en route to the Pacific Theater when Japan surrendered. One of the ships participated in Operation Dragoon and two were attacked by German guided missiles.

USS Stewart (DE–238) is an Edsall-class destroyer escort, the third United States Navy ship so named. This ship was named for Rear Admiral Charles Stewart, who commanded USS Constitution during the War of 1812. Stewart is one of only two preserved destroyer escorts in the U.S. and is the only Edsall-class vessel to be preserved. She is on display in Galveston, Texas as a museum ship and is open to the public.

Texas is a state in the South Central region of the United States. At 268,596 square miles (695,660 km2), and with more than 30 million residents in 2022, it is the second-largest U.S. state by both area and population. Texas shares borders with the states of Louisiana to the east, Arkansas to the northeast, Oklahoma to the north, New Mexico to the west, and the Mexican states of Chihuahua, Coahuila, Nuevo León, and Tamaulipas to the south and southwest; and has a coastline with the Gulf of Mexico to the southeast.

Rio de Janeiro, or simply Rio, is the capital of the state of the same name, Brazil's third most populous state, and the second most populous city in Brazil, after São Paulo. Listed by the GaWC as a beta global city, Rio de Janeiro is the sixth most populous city in the Americas. Part of the city has been designated as a World Heritage Site, named "Rio de Janeiro: Carioca Landscapes between the Mountain and the Sea", on 1 July 2012 as a Cultural Landscape.

Brazil, officially the Federative Republic of Brazil, is the largest country in South America and in Latin America. At 8.5 million square kilometers (3,300,000 sq mi) and with over 217 million people, Brazil is the world's fifth-largest country by area and the seventh 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 and the Federal District. It is the only country in the Americas to have Portuguese as an official language. It is one of the most multicultural and ethnically diverse nations, due to over a century of mass immigration from around the world, and the most populous Roman Catholic-majority country.

The Rudderow-class destroyer escorts were destroyer escorts launched in the United States in 1943 to 1945. Of this class, 22 were completed as destroyer escorts, and 50 were completed as Crosley-class high speed transports and were re-classified as high speed transport APDs. One ship was converted to an APD after completion. They served in World War II as convoy escorts and anti-submarine warfare ships.

Colombia, officially the Republic of Colombia, is a country in South America with insular regions in North America—near Nicaragua's Caribbean coast—as well as in the Pacific Ocean. The Colombian mainland is bordered by the Caribbean Sea to the north, Venezuela to the east and northeast, Brazil to the southeast, Ecuador and Peru to the south and southwest, the Pacific Ocean to the west, and Panama to the northwest. Colombia is divided into 32 departments. The Capital District of Bogotá is also the country's largest city. It covers an area of 1,141,748 square kilometers, and has a population of around 52 million. Colombia's cultural heritage—including language, religion, cuisine, and art—reflects its history as a Spanish colony, fusing cultural elements brought by immigration from Europe and the Middle East, with those brought by enslaved Africans, as well as with those of the various Indigenous civilizations that predate colonization. Spanish is the official state language, although English and 64 other languages are recognized regional languages.

The Philippine Navy (PN) is the naval warfare service branch of the Armed Forces of the Philippines. It has an estimated strength of 24,500 active service personnel, including the 8,300-strong Philippine Marine Corps. It operates 82 combat vessels, 14 auxiliary vessels, 25 manned aircraft and 8 unmanned aerial vehicles. It shares the responsibility of patrolling the maritime borders with the Philippine Coast Guard, a formerly attached unit which became a separate maritime law enforcement agency in 1998.
