The Armed Forces of São Tomé e Príncipe (FASTP, Forças Armadas de São Tomé e Príncipe in Portuguese) are the armed forces of the island nation of São Tomé and Príncipe, off the coast of West Africa. The islands' military consists of a small land and naval contingent, with a limited budget. Sitting adjacent to strategically important sea lane of communication in the Gulf of Guinea, due to recent concerns about regional security issues including security for oil tankers transiting the area, the US military and other foreign navies have increased their engagement with the FASTP, providing the country with assistance in the form of construction projects and training missions, as well as integration into international information and intelligence sharing programs.
The FASTP are a very small military, consisting of four branches: Army (Exército), Coast Guard (Guarda Costeira also called "Navy"), Presidential Guard (Guarda Presidencial), and the National Guard. There is no air force. Since the end of the Cold War, the nation's military budget has been steadily decreased. Despite the discovery of large oil reserves in the mid-2000s the Sao Tomean military is largely reliant upon foreign financial assistance, and it remains the least funded force in Africa. In the 2005 fiscal year, military expenditures were $581,729, about 0.8% of São Tomé and Príncipe's gross domestic product. A 2004 estimate put military manpower availability (males age 15–49) at 38,347, with a "fit for military service" estimate of 20,188. In a 2009 article, it was reported the FASTP consisted of a total of just 300 soldiers, which was reduced from 600 after an unsuccessful coup attempt in 2003 resulted in a reorganization aimed at ensuring an apolitical military that is subordinated to civilian political structures. It is believed that the Army is formed into two companies, headquartered on the main island of Sao Tome, with a detachment on the smaller island of Principe.
São Tomé and Príncipe's military is a small force – reputedly the smallest in Africa – with almost no resources at its disposal and would be wholly ineffective operating unilaterally with no force projection capabilities. Additionally, legislatively there is no requirement for personnel to deploy overseas and there is no reserve capacity. The limited equipment that the military possesses is reported nearing the end of its lifespan and while its basic small arms are considered simple to operate and maintain they may be of limited serviceability and may require refurbishment or replacement after 20–25 years in tropical climates. Poor pay, working conditions, and alleged nepotism in the promotion of officers have caused tension in the past, as evidenced by unsuccessful coups that were launched in 1995 and 2003.
