Armament
These multi-purpose frigates can be used in the anti-submarine, anti-aircraft or surface combat roles. Their armament reflects that.
Their primary surface armament consists of two quad launchers for the RGM-84 Harpoon anti-ship missile, which has a range of 120 kilometres. Backing this up is a 76 mm Oto Melara gun, which has both anti-ship and anti-air capabilities.
Air defence is provided by the Sea Sparrow vertical launch system, which uses semi-active radar to find its target and has a range of 14 km. 16 VLS cells are mounted on the port external bulkhead of the hangar. A Goalkeeper system provides close-range air defence. It fires 30 mm rounds and can fire up to 4,000 rounds per minute, with a range of 200 metres to 3 km.
For anti submarine warfare, each ship is equipped with two twin torpedo launchers, firing Mark 46 torpedoes; and carries one Westland Lynx helicopter. The helicopter is also armed with 2 Mk 46 torpedoes, and carries dipping sonar and forward looking infrared (FLIR) systems.
