Class particular

The Air Defence Frigate platform is based on the successful Kortenaer class. The AAW suite has been improved by adding a Mk13 mod 1 launcher with SM-1 capability. The sensor suite has been adapted by replacing the WM25 search and tracking radar with a DA05 air surveillance radar and a STIR 1.80 tracking and illumination radar and adding an additional STIR 2.40 tracking and illumination radar aft. The AAW suite provides three layers of defence, ensuring an AAW umbrella at task force level.

 

Later the DA05 air surveillance radar was replaced by SMART-S 3D radar. The ships are provided with command facilities for a Task Group Commander and his staff. In consistence with specialisation to the AAW functionality the medium calibre gun and the hangar are sacrificed.

 

The two frigates have been sold to Chile and are now sailing under the names FFG-14 Latorre (former F812) and FFG-11 Capitan Prat (former F813).
