Pentagon plans $40m fiber optic cable from Guantanamo Bay to US mainland "It would be a mistake to assume that some potential use of fiber optic communication lines" at Guantanamo Bay "is any indication of how long the detention center will be around," said Breasseale. Our goal remains to close the detention facility. We have no plans to close the naval station there. The Guantanamo Bay naval base is built on Cuban land leased to the United States in 1903. Terror suspects have been detained at the prison there since 2001.
