Fact Sheet: The Republic of Singapore Navy's Formidable-class Frigates and Sikorsky S-70B Seahawk Naval Helicopters

Background

The frigate programme first started in the mid-1990s, to replace the RSN's fleet of ageing Sea Wolf-class Missile Gun Boats that were nearing the end of their operational lifespan. The Formidable-class frigates are the principal combatants of the Republic of Singapore Navy (RSN), and form the sharp edge of its fighting force. The commissioning of the first frigate in 2007 marked a significant milestone in the RSN's 3rd generation transformation into a highly sophisticated and networked maritime force. 

High-end Warfighting Capabilities

Effective Operations Across Dimensions of Naval Warfare. Equipped with a wide-range of sensor and weapon systems, the frigates are capable of conducting operations across all three dimensions of naval warfare – air, surface and underwater. Sophisticated sensors such as the Multi-Function Radar enable the frigates to maintain air surveillance, while advanced weaponry like the Aster surface-to-air missiles allow the ships to provide effective air defence over a large area. The indigenously developed Combat Management System, developed by the Defence Science and Technology Agency and DSO National Laboratories, provides command and control of the various sensor and weapon systems onboard the frigates. It facilitates sense-making through functions such as sensor management, picture compilation, threat evaluation and weapon assignment.

Enhanced Connectivity and Better Situational Awareness. The comprehensive communications suite also connects the frigates with units at sea and ashore, including aircraft operating in the maritime theatre. Through the Singapore Armed Forces' Integrated Knowledge-based Command and Control network, the task force at sea is able to link up effectively with their sensors and shooters to gain a better level of awareness and speed up their decision-making cycle, allowing them to stay ahead of adversaries.

Integration with Organic Naval Helicopters

Sense Faster, See and Strike Further. The capabilities of the frigates are further enhanced with the integration of the Sikorsky S-70B Seahawk Naval Helicopters. The naval helicopters come with state-of-the-art avionics, sensors and sense-making systems. They play an essential role in the anti-surface and anti-submarine dimensions of warfare, and with the longer range and wider reach of the helicopters, it allows the frigate to sense faster, see and strike further. Each naval helicopter is operated by a crew of four, comprising two pilots from the Republic of Singapore Air Force (RSAF), and a Sensor Supervisor and Tactical Coordination Officer from the RSN. 

Optimal Performance to meet the RSN’s Operational Requirements. These capabilities have strengthened the maritime awareness and mission effectiveness of the RSN. Integration between the vessels and their organic embarked naval helicopters are significant force-multipliers, and enable the RSN to undertake a wider spectrum of missions including maritime security and counter-piracy operations, naval warfare and supporting Humanitarian Assistance and Disaster Relief efforts around the world.
