Maritime response following the September 11 attacks

The Port of New York and New Jersey is the port district of the New York-Newark metropolitan area, encompassing the region within approximately a 25-mile (40 km) radius of the Statue of Liberty National Monument. It includes the system of navigable waterways in the New York–New Jersey Harbor Estuary, which runs along over 770 miles (1,240 km) of shoreline in the vicinity of New York City and northeastern New Jersey, as well as the region's airports and supporting rail and roadway distribution networks. Considered one of the largest natural harbors in the world, the port has become the second busiest port by tonnage in the United States as of 2019, and the busiest on the East Coast.The port is the nation's top gateway for international flights and its busiest center for overall passenger and air freight flights. There are two foreign-trade zones (FTZ) within the port.

New York Harbor is at the mouth of the Hudson River where it empties into New York Bay near the East River tidal estuary, and then into the Atlantic Ocean on the east coast of the United States. It is one of the largest natural harbors in the world, and is frequently named the best natural harbor in the world. It is also known as Upper New York Bay, which is enclosed by the New York City boroughs of Manhattan, Brooklyn, and Staten Island and the Hudson County, New Jersey, municipalities of Jersey City and Bayonne. The name may also refer to the entirety of New York Bay including Lower New York Bay. Although the United States Board on Geographic Names does not use the term, New York Harbor has important historical, governmental, commercial, and ecological usages.

The 1899 America's Cup was the 10th challenge for the Cup. It took place in the New York City harbor and consisted of a best of five series of races between the defender, Columbia, entered by the New York Yacht Club, and Sir Thomas Lipton's Shamrock, representing the Royal Ulster Yacht Club. Columbia won all three races against Shamrock.

The 1920 America's Cup was the 13th challenge for the Cup and the first since 1903. It took place in New York Harbor and consisted of a best-of-five series of races between the defender Resolute, entered by a syndicate of New York Yacht Club members headed by Henry Walters, and Shamrock IV, the fourth in Sir Thomas Lipton's line of Cup challengers. Charles Francis Adams III was the skipper of Resolute in this race. Despite being disabled in the first race and losing the second, Resolute won the final three races and in doing so retained the Cup on behalf of the NYYC, continuing the club's unbroken record of defending the America's Cup. The 1920 America's Cup was originally scheduled to take place in 1914 but was postponed upon the outbreak of World War I. The 13th Cup challenge was the last to take place in New York, and the first held under the Universal Rule of measurement. Due to the rule, Shamrock IV owed Resolute seven minutes time.

The 1903 America's Cup was the 12th challenge for the Cup. It took place in the New York City harbor and consisted of a best of five series of races between Reliance, the fourth of Nathaniel Herreshoff's defenders for the cup, entered by the New York Yacht Club; and Shamrock III, representing the Royal Ulster Yacht Club and also the third of Sir Thomas Lipton's Cup challengers. Reliance won the first three races, defending the cup. It was the last race for the America's Cup that would take place under the Seawanhaka rule.

The 1901 America's Cup was the 11th challenge for the Cup. It took place in the New York City harbor and consisted of a best of five series of races between the defender Columbia, entered by the New York Yacht Club for the second time, and Sir Thomas Lipton's Shamrock II, representing the Royal Ulster Yacht Club. Columbia won all three races, the last being won with handicap, defending the cup.

SS El Sol was a cargo ship built in 1910 for the Morgan Line, a subsidiary of the Southern Pacific Company. During World War I, she was known as USAT El Sol in service with the United States Army and as USS El Sol (ID-4505) in service with the United States Navy. At the end of war, she reverted to her original name of SS El Sol. SS El Sol was one of four sister ships that carried cargo and a limited number of passengers for the Morgan Line. She was acquired by the U.S. Army after the United States entered World War I in April 1917, and converted to carry horses and mules to France. In August 1918, the ship was transferred to the U.S. Navy and continued transporting animals through the end of the war. El Sol returned to the Morgan Line in 1919 and sailed with them until March 1927, when she sank in New York Harbor after colliding with Sac City of the American Diamond Lines. A portion of the ship's cargo was salvaged but the ship was scrapped later in the year.

Liberty Island is a federally owned island in Upper New York Bay in the United States. Its most notable feature is the Statue of Liberty (Liberty Enlightening the World), a large statue by Frédéric Auguste Bartholdi that was dedicated in 1886. The island also contains the Statue of Liberty Museum, which opened in 2019 and exhibits the statue's original torch. Long known as Bedloe's Island, it was renamed by an act of the United States Congress in 1956. Part of New York State, the island is an exclave of the New York City borough of Manhattan, surrounded by the waters of Jersey City, New Jersey. Liberty Island became part of the Statue of Liberty National Monument in 1937 through Presidential Proclamation 2250, signed by President Franklin D. Roosevelt. In 1966, it was listed on the National Register of Historic Places as part of Statue of Liberty National Monument, Ellis Island and Liberty Island.

The Statue of Liberty (Liberty Enlightening the World; French: La Liberté éclairant le monde) is a colossal neoclassical sculpture on Liberty Island in New York Harbor in New York City, in the United States. The copper statue, a gift from the people of France to the people of the United States, was designed by French sculptor Frédéric Auguste Bartholdi and its metal framework was built by Gustave Eiffel. The statue was dedicated on October 28, 1886. The statue is a figure of Libertas, a robed Roman liberty goddess. She holds a torch above her head with her right hand, and in her left hand carries a tabula ansata inscribed JULY IV MDCCLXXVI (July 4, 1776 in Roman numerals), the date of the U.S. Declaration of Independence. A broken shackle and chain lie at her feet as she walks forward, commemorating the recent national abolition of slavery. After its dedication, the statue became an icon of freedom and of the United States, seen as a symbol of welcome to immigrants arriving by sea. Bartholdi was inspired by a French law professor and politician, Édouard René de Laboulaye, who is said to have commented in 1865 that any monument raised to U.S. independence would properly be a joint project of the French and U.S. peoples. The Franco-Prussian War delayed progress until 1875, when Laboulaye proposed that the French finance the statue and the U.S. provide the site and build the pedestal. Bartholdi completed the head and the torch-bearing arm before the statue was fully designed, and these pieces were exhibited for publicity at international expositions. The torch-bearing arm was displayed at the Centennial Exposition in Philadelphia in 1876, and in Madison Square Park in Manhattan from 1876 to 1882. Fundraising proved difficult, especially for the Americans, and by 1885 work on the pedestal was threatened by lack of funds. Publisher Joseph Pulitzer, of the New York World, started a drive for donations to finish the project and attracted more than 120,000 contributors, most of whom gave less than a dollar (equivalent to $29 in 2020). The statue was built in France, shipped overseas in crates, and assembled on the completed pedestal on what was then called Bedloe's Island. The statue's completion was marked by New York's first ticker-tape parade and a dedication ceremony presided over by President Grover Cleveland. The statue was administered by the United States Lighthouse Board until 1901 and then by the Department of War; since 1933 it has been maintained by the National Park Service as part of the Statue of Liberty National Monument, and is a major tourist attraction. Public access to the balcony around the torch has been barred since 1916.

The Statue of Liberty Museum is located on Liberty Island in New York City. The museum opened on May 16, 2019, and is focused on the creation, meaning, and history of the Statue of Liberty (formally Liberty Enlightening the World), a large statue by Frédéric Auguste Bartholdi which the people of France gave to the people of the United States in 1886.

The Robbins Reef Light Station is a sparkplug lighthouse located off Constable Hook in Bayonne, Hudson County, New Jersey, United States, along the west side of Main Channel, Upper New York Bay. The tower and integral keepers quarters were built in 1883. It replaced an octagonal granite tower built in 1839. The U.S. Coast Guard owned and operated the light station until the 2000s.

To the Struggle Against World Terrorism (also known as the Tear of Grief and the Tear Drop Memorial) is a 10–story sculpture by Zurab Tsereteli that was given to the United States as an official gift from the Russian government as a memorial to the victims of the September 11 attacks in 2001, and the 1993 World Trade Center bombing. It stands at the end of the former Military Ocean Terminal in Bayonne, New Jersey. Ceremonial groundbreaking occurred on September 16, 2005, in a ceremony attended by Russian President Vladimir Putin. The monument was dedicated on September 11, 2006, in a ceremony attended by former U.S. President Bill Clinton.
