Radar Herakles

Radar Herakles

Herakles is a passive electronically scanned array multi-function radar manufactured by Thales Group. It is installed on board the FREMM multipurpose frigates and the Formidable-class frigates of the Republic of Singapore Navy.

It has a track capacity of 400 air and surface targets and is able to achieve automatic target detection, confirmation and track initiation in a single scan, while simultaneously providing mid-course guidance updates to the MBDA Aster missiles launched from the ship.

Design

A true multifunction radar, it has convincingly demonstrated its capabilities on board of the Formidable class and FREMM class vessels. The system offers high-performance ECCM features as well as low radar cross section to optimize vessel stealth. Herakles represents the state-of-the-art in naval radar technology withintegrated IFF with mode 5 and mode S. Being fully solid-state and with redundancies for vital functions, it offers an unmatched availability.

  • Designed to be the sole radar on-board high-value ships
  • Long range surveillance concurrently with area and self-defence in one single mode
  • Multi-beam surveillance for optimized dwell-time over full sector
  • Excellent littoral performance
  • Optimal integration with ASTER missiles, quali ed with live rings
