The Republic of Singapore Navy (RSN) is the maritime service branch of the Singapore Armed Forces (SAF) responsible for defending the country against any seaborne threats and as a guarantor of its sea lines of communications. The RSN traces its origins to the Royal Navy when Singapore was still a crown colony of the British Empire. The service was formally established in 1967, two years after its independence from Malaysia in 1965, and had undergone a substantial modernisation ever since – which has led them into becoming the most powerful navy in Southeast Asia.

The Singapore Armed Forces (SAF) are the military of the Republic of Singapore, responsible for protecting and defending the security interests and the sovereignty of the country. A component of the Ministry of Defence (MINDEF), the armed forces have four service branches: the Army, Navy, Air Force, and Digital and Intelligence Service. An integrated force, it is one of the most capable, robust, technologically sophisticated and powerful militaries in the Southeast Asia region. The SAF is headed by the chief of defence force, appointed by the President, on the advice of the Cabinet.
