In addition to contributing to Mistraltype LHD programmes and the Brave logistic support vessel project in cooperation with DCNS, STX France's Saint-Nazaire shipyard also proposes its own range of frigates and corvettes. This effort began with the New-Generation Surveillance Frigate, a modernised version of the eight Floreal-class vessels delivered to the French and Moroccan Navies in the 1990s and 2000s. More recently, STX France took the world by surprise when it announced the Defendseas corvette based on a ground-breaking concept. The design arose as part of an R&D project looking at new concepts for civil and naval vessels. A dedicated project team has been in place since 2013.
Drawing on advances by the Ecorizon® green lifecycle R&D team, which have brought significant improvements in the energy efficiency and environmental performance of STX France products,
Defendseas integrates various technological building blocks and
innovations with an architecture optimised to meet customer needs.
The result is a complete toolbox of new ideas that can be mixed and matched to expand the capabilities of warships of all displacements according to the customer's operational requirements.
The Defendseas team has also built on STX France's expertise in civil and naval shipbuilding to propose a platform combining proven solutions with an innovative architecture and layout. One of the eye-catching features of the corvette design is an ingenious helo handling system in the form of a lift that fits between two sections of a retractable deck. As a result, the superstructure volume normally occupied by the hangar can be reappropriated, with all storage spaces moved to the lower deck and all platform management and accommodation located separately.
Overall, the new design offers better use of available volumes. The hangar opens directly aft onto a 500sq.m modular space divided
into three mission-configurable bays (typically for 9.5m heavy RHIBs) and four more for 20 foot containers (for additional RHIBs or light military vehicles). The rigid-hull inflatable boats are launched and recovered one or two at a time via a stern ramp and two side
doors. All RHIBs and containers are handled by a single overhead crane. The superstructure combines a panoramic bridge offering 360° vision, the flight deck control station, the living quarters and all operational areas, including the ops room with its six to eight consoles. The superstructure also houses a space for an unmanned
aircraft system (UAS). The Defendseas combat system includes 12 vertical launch cells near the flight deck for surface-to-air missiles, four anti-ship missiles stored in paired launchers, a 76mm gun flanked by a pair of 12.7mm machine guns on the forward deck, and two remotely controlled 20mm machine guns aft. The sensor suite features a 3D search radar and an optronicfire control system. Last but not least, the super.structure, weapon systems and payload are
all designed for optimal stealth.
