Greece’s Second FDI Frigate Receives PSIM Integrated Mast

The hull of the second Greek FDI HN frigate, Nearchos (F602), was floated out of the dry dock on September 19, 2024. The innovative integrated mast PSIM (Panoramic Sensor & Intelligence Module) was fitted on the frigate today, October 23, 2024. Approximately a month after the technical launch of the second Greek FDI HN frigate Nearchos (F602) from its dry dock at the Naval Group shipyards in Lorient, France, the final structural component—the PSIM integrated mast—was installed today on the ship. This mast, along with the inverted bow, is a key characteristic of the FDI design. The Naval Group’s mast is a separate module, manufactured independently of the hull and well in advance of sea trials. It can be powered up, tested, or even used for training purposes while still onshore. Weighing 150 tonnes and standing 42 meters tall, the integrated steel mast, known as the Panoramic Sensors and Intelligence Module (PSIM), incorporates the ship’s Command Information Center (CIC) with the latest version of the SETIS Combat Management System (CMS), a planning room for mission command staff during flagship operations, and one of the two digital data processing centers (the other is located aft in the hull for survivability). The mast also houses the majority of the ship’s above-water sensors, providing continuous 360° surveillance. My story for Naval News, here.
