Guantanamo Bay Naval Base, officially known as Naval Station Guantanamo Bay or NSGB, is a United States military base located on 45 square miles of land and water at Guantánamo Bay, Cuba, which the US leased for use as a coaling and naval station in 1903 for $2,000 payable in gold per year until 1934, when the payment was set to match the value in gold of the 1903 lease; in 1974, the yearly rental was set to $4,085. The base is on the shore of Guantánamo Bay at the southeastern end of Cuba.
