On the other hand, the PF 4921 is a light frigate for executing anti-air, anti-surface and anti-submarine warfare. However, it sacrifices range – which is about a third less than the PF 4501 – for vastly enhanced combat capabilities. Armament is a 76 mm main gun, a vertical launch unit for the evolved Sea Sparrow Missile (ESSM), a Phalanx or SeaRAM CIWS, and six crew-served as well as remotely operated machine guns. Mounted aft are two quad packed Harpoon surface-to-surface missile launchers and a triple torpedo tube launcher. Sensors shown on the concept ship include a CEAFAR radar system, a hull mounted sonar and a towed array sonar system. Ship’s complement is 141.
