radar to introduce new solid-state transmitters in SIGMA 10514-based (Patrullera Oceanica de place of magnetron and TWT transmitters, which Largo Alcance) POLA class vessels, in addition provide high responsiveness (no ‘warm-up’ time to the selection by the Brazilian Navy for the new is required), improved operational availability, Tamandaré-class corvettes. Thales Nederland safety benefits (no high voltage required), graceful also offers the scalable family of CWI transmitters degradation in case of failure and reduced life-cycle called CWITX including the 1.5- and 2-kW costs. Robust target tracking, including stealth power modules, compliant with the SeaSparrow, targets, is ensured by the large dynamic range of ESSM Block 1 and Block 2 (NATO Support and low noise receivers in combination with advanced Procurement Organization compliant), as a form, coherent Doppler processing, Thales Nederland fit, function replacement for older systems as well says. The electro-optical suite comprises a midas new installations. waveband (3-5 µm) IR camera, colour zoom and Thales Nederland developed the Pharos phased monochrome TV track cameras and an eye-safe array multi-target tracking and gun fire control laser range finder allowing for a complete passive radar, as a natural successor to the company’s Lirod search and track. The STIR 1.2 EO Mk2 system Mk2 fire-control radar. The new Ka band passive has been designed, thanks to the integration with phased array radar system has been designed for an I-band CWI transmitter, to control semi-active multiple target tracking and integrated ammunition guided point defence missile systems (a single control allowing it to extend the inner-layer defence weapon in the air at any given time), with emphasis of any medium calibre gun system, ranging from on NATO Sea Sparrow and ESSM (Evolved 30 to 76 mm. Conceived as a ship self-defence SeaSparrow Missile) Block 1. With a radar range of system against sub- and supersonic sea-skimming respectively 120 and 36 km in the I- and K- bands, anti-ship missiles as well as for the engagement according to Thales Nederland, the STING EO Mk2 of small surface targets in littoral environment, offers excellent sub-clutter tracking of targets in balancing costs with performances, Thales severe littoral environments, thanks also to the Nederland has selected a radar director featuring K-band small antenna beam width which greatly a passive phased array antenna architecture with a reduces low elevation multipath errors. ECCM features include waveform and The STING EO Mk2 has gained a significant international market frequency agility in both bands, higher success, the latest disclosed customers being the Marine dynamic range processing, digital pulse Nationale and the Mexican Navy, and has been selected by the Brazilian Navy. ©Thales Nederland compression and a lower probability of intercept. Ship installation is simplified by the reduced weight of the STING EO Mk2 director above-deck assembly of 850 kg (including radars and EO) as well as by the packing of below-decks equipment – a supply and amplifier cabinet, a liquid cooling cabinet and an air drier – totalling just over 500 kg. The STING EO Mk2 has gained a significant international market success, being in operational use or on order by around 15 navies, the latest disclosed customers being the French Marine Nationale for her under-construction Frégates de Défense et d’Intervention (FDI) by Naval Group and the Mexican Navy for the under-delivery Damen
