RSN to fit final Formidable-class frigate with Thales fire-control radar

SINGAPORE, -- The Republic of Singapore Navy (RSN) is to equip the last of its six Formidable-class guided-missile frigates with the Thales STIR 1.2 EO Mk 2 radar and electro-optical fire-control director system, a senior RSN official confirmed with IHS Jane's at the IMDEX 2015 exhibition.

The system has been progressively introduced to the class since around 2013, with the only vessel yet to receive the fit being second-in-class RSS Intrepid (69), said the official during a tour of the frigate at Changi Naval Base. " Intrepid will be the last one to be equipped with the system and is currently preparing for the installation", said the official. No timeline was given, however, for when work will be complete.

According to IHS Jane's C4ISR & Mission Systems: Maritime , the STIR EO Mk 2 system has the ability to detect and track agile and stealthy targets in densely cluttered environments, such as those encountered in littoral waters.

The system provides fire-control for naval guns, such as the Oto Melara 76/62 Super Rapid gun currently fitted to the Formidable-class ships. The STIR EO Mk 2 can also be integrated with a continuous wave illumination transmitter to support the guidance of semi-active homing weapons.

Besides the STIR EO Mk 2 system, the Formidable-class frigates are also equipped with the Thales Herakles E/F-band multifunction radar that provides surveillance, target indication, and missile guidance support.
