The Port of Jacksonville (Jaxport) is an international trade seaport on the St. Johns River in Jacksonville, Florida. The 14th largest container port in the United States, it carries about 18 million short tons of cargo each year and has an annual economic impact of over $31 billion, including 138,500 jobs across the state of Florida related to cargo moving through the port. It handled 1,338,000 containers, and is the second largest handler of vehicles in the United States with 696,500 in 2019. History English sailors traded ammunition and guns to the French from Fort Caroline for food and a boat in 1565, the first international commerce recorded in the New World. Because of this, the port uses the phrase, Jacksonville: America's First Port. After Cowford was renamed Jacksonville, a petition dated June 15, 1822, was sent to Secretary of State John Quincy Adams, asking him to designate the city as a port of entry for the United States. Jacksonville's St. Johns River is one of the best natural seaports in the Southeast, and shipping has always been an important component of the local economy. Before Florida became a state in 1845, cotton and timber were traded and shipped at the port. The Great Fire of 1901 destroyed the port facilities as well as most of the city. Docks and wharfs were among the first items rebuilt by businesses. In 1907, the federal government helped pay for main channel in the river to be dredged to a depth of . The city of Jacksonville began to exert control over the port at Talleyrand in 1912 and a $1.5 million bond referendum passed in 1913 to pay for construction of municipal docking facilities. The U.S. Army Corps of Engineers performed the harbor dredging in 1916, 1952, 1978 and 2003, when the channel was deepened to , , and , respectively. The United States Navy had no base at the Port of Jacksonville until shortly before World War II when two facilities were constructed. Today, the Naval Station Mayport, Naval Air Station Jacksonville, Blount Island Command (Marines) and nearby Naval Submarine Base Kings Bay form the third largest military presence in the United States. Following the war, little or no money was spent on the public docks at the port, and they deteriorated until many were unusable. Because of this, Jacksonville missed out on much of the shipping boom of the Post-World
