Dawn of unmanned systems

2004

Unmanned surface vehicle cruising in the water with advanced technology.

The RSN was possibly one of the first few navies in the world to deploy an Unmanned Surface Vessel (USV) for actual operation. During RSS Resolution's deployment to the Northern Arabian Gulf, the Protector USV was used in the protection of critical infrastructure at sea from terrorist attacks.

Welcoming the First Formidable-class Frigate

RSS Formidable docked at a port with Singapore flags and naval decorations.

The first of the RSN’s six frigates, RSS Formidable was launched on 7 January 2004. Equipped with advanced sensor and weapon systems, and with enhanced anti-air, anti-surface and anti-submarine warfare capabilities, the introduction of the frigates enabled the RSN to undertake a wide spectrum of missions.

Aiding our neighbours in need

2005

Submarine surfaced in the ocean with a misty backdrop and rising waves.

This year saw the expansion of the RSN's underwater capabilities with the acquisition of the Archer-class submarine from Sweden. The Archer-class is equipped with Air Independent Propulsion technology, which further enhances the stealth capabilities of our submarines. In 2013, the year the Archer-class project was completed, the RSN announced further development for its submarine force: we are to acquire Type 218SG submarines from Germany. This marks the RSN's venture into customising the design of our underwater assets to suit Singapore's unique maritime environment.
