The Bolivian Naval Force (Spanish: Fuerza Naval Boliviana), formerly known as the Bolivian Navy (Armada Boliviana) is a branch of the Bolivian Armed Forces. As of 2008, the Bolivian Naval Force had approximately 5,000 personnel. Although Bolivia has been landlocked since the War of the Pacific in 1879, Bolivia established a River and Lake Force (Fuerza Fluvial y Lacustre) in January 1963 under the Ministry of National Defense. It consisted of four boats supplied from the United States and 1,800 personnel recruited largely from the Bolivian Army. The Bolivian Navy was renamed as the Bolivian Naval Force (Fuerza Naval Boliviana) in January 1966, but it has since been called the Bolivian Navy (Armada Boliviana) as well. It became a separate branch of the armed forces in 1963. Bolivia has large rivers which are tributaries to the Amazon which are patrolled to prevent smuggling and drug trafficking. Bolivia also maintains a naval presence on Lake Titicaca, the highest navigable lake in the world, across which runs the Peruvian frontier.
