Puerto Belgrano Naval Base

Base Naval Puerto Belgrano (Port Belgrano Naval base) is the largest naval base of the Argentine Navy, situated next to Punta Alta, near Bahía Blanca, about 700 km south of Buenos Aires. It is named after Manuel Belgrano.

Home of the Argentine Fleet, it concentrates all major ships and arsenals, and is close to the main bases of the other Navy organisations: Marine's camp Baterías and Naval aviation's air base Comandante Espora.

History
Designed by prominent local engineer Luis Huergo, Puerto Belgrano opened on November 30, 1896 under the name Puerto Militar (Military Port). In 1911, the French-owned railway company Ferrocarril Rosario y Puerto Belgrano opened a broad gauge (5 ft) line between Puerto Belgrano and Rosario. The harbor was renamed Puerto Belgrano in 1923.

The base grew in importance with the size of the fleet. During World War I and World War II the s ARA Moreno and ARA Rivadavia were docked here, and during the Cold War the aircraft carriers ARA Independencia and ARA Veinticinco de Mayo were docked at this base.

The shipyard continues doing maintenance and refits of vessels and submarines.

On April 2006, the Royal Navy's Antarctic patrol vessel HMS Endurance (A171) entered Puerto Belgrano for repairs after damaging its rudder while in Antarctica in February. It was the first time since the end of the 1982 Falklands War (Guerra de las Malvinas) that a British Royal Navy ship had entered the Argentine naval base.
