HS Grigororopoulos is a Roussen class 7-strong class of British-designed Fast Attack Craft for the Hellenic Navy.
The class is named after its lead ship, which in turn is named after Lt Nikolaos Roussen, a World War II submarines officer who was killed in the suppression of the Navy mutiny in April 1944.
The modernization program of the Hellenic Navy in the late '90s included the construction of three modern missile boats and was signed on January, 2000. The construction took place at the Elefsis Shipyards, while Vosper Thornycroft (now BAE Systems Surface Ships) provide the necessary design, logistical support and equipment for the ships. On August, 2003 and September, 2008 options that provided the acquisition of four more vessels were activated with the last ship to be commissioned in 2013.
The plans of the Roussen Class missile boats are based on smaller Vita class boats serving in the navies of Qatar, as well as similar size vessels built for Oman and other countries. The hull is made of steel and the superstructure is made of aluminum, while the company Vosper Thornycroft (now BAE Systems Surface Ships) provides the electricity transmission system, the management board, electrical equipment and systems countermeasures.
The main armament of the ships are eight Exocet MM40 Block II/III anti-ship missiles with a range of 180 km. They are complemented by an Otobreda 76 mm naval gun in the bow and two smaller 30mm cannons as secondary weapons. located on the ships' superstructure. The vessel's primary anti-air and anti-missile weapon is the RIM-116 RAM missile system which comprises an onboard Mk-49 launcher with 21 missiles, as well as the DR300 and AR900 electronic support measures systems and the SRBOC decoy launcher.
The sensor suite responsible for the timely identification and homing of surface and air targets includes the MW08 3D G-band surveillance radar, the Mirador electro-optical target tracker and the Scout MkII low probability of intercept radar which is being controlled by the TACTICOS combat management system.
