Expendable Decoys Directorate, IDS utilizes a lightweight, non-penetrative 36-tube launcher mount able to fire Long Range Chaff Rocket (LRCR) confusion chaff, MRCR distraction chaff, BT-4 seduction chaff, Heatrap IR seduction decoys, WIZARD corner reflectors, and LESCUT acoustic countermeasures rounds. NGDS IN SERVICE An NGDS launcher on board the French Navy Horizon frigate Chevalier Paul. (Richard Scott/ NAVYPIX) 12 tubes, with groups of three barrels angled at 10°, 40°, 60° and 135°. DL-6T and DL-12T firing angles were selected on the basis of extensive modelling performed by the Danish Defence Research Establishment. The tubes are elevated at 45 degrees, enabling firing of either mortar or rocket-propelled 130mm decoy types. CENTURION APPROACHING The option to utilize a fully trainable launcher has hitherto been unavailable to those navies using the widely-sold SRBOC/NATO Sea Gnat family of 130-mm countermeasures cartridges. Recognizing this gap, Chemring Countermeasures in 2009 began private venture development of its Centurion launcher concept with the objective of engineering a trainable system that is fully compatible with existing 130-mm rounds, but also able to optimize the performance of its new 130-mm chaff and IR variable range cartridges. Following early trials of an "Alpha" prototype, Chemring has invested its own funds in the manufaccontinued on page 38 STANDING GUARD Denmark's Terma continues to market its C-Guard 130-mm countermeasures system - previously known as the Soft-Kill Weapon System - having to date sold over 150 systems worldw ide. Customers for either the full system, or the inboard decoy launch control system alone, include the Australian, Columbian, Chilean, Danish, Indonesian, Netherlands, Norwegian, Romanian and US navies.  While based on fixed launcher sets, Terma has sought to address the limitations of the Mk 36 DLS by offering alterative DL-6T and DL-12T multi-angular barrel sets. DL-6T launchers are fitted with six tubes, with pairs angled to 20°, 40° and 135° in the azimuth plane relative to the ship's head. The larger DL12T launcher group is configured with The Centurion launcher comprises 12 vertically-stowed barrels on a rotating plinth. The launcher trains on to the appropriate bearing and then depresses the selected launcher barrel to the desired firing angle as determined by the system firing algorithms. (Chemring) The Journal of Electronic Defense | October 2016 Now a product in the portfolio of French systems and sensors group Sagem, the New Generation Dagaie System (NGDS) was developed as the successor to the widely sold Dagaie and Dagaie Mk 2 decoy systems. Adopting a modular philosophy, NGDS is compatible with a range of decoy rocket types, and will be capable of providing full co-ordination between anti-missile and anti-torpedo functions. NGDS uses a twin-axis launcher trainable in elevation and azimuth to enable accurate decoy placement to counter specific threat types. To meet the specific needs of the French Navy, countermeasures specialist Lacroix Defense has developed a new generation of NGDS-compatible SEALEM and SEALIR decoy rockets respectively deploying advanced RF and IR payloads. With a variable range between 100 meters and 3,000 meters, these are suitable for use in seduction, distraction or confusion modes according to the selected range, deployment pattern and burst point. NGDS has been installed on the French Navy's two new Horizon anti-air warfare frigates, and is also being fit- ted to the new FREMM frigates delivered to the French, Moroccan and Egyptian navies. In addition, variants of NGDS have been introduced to service on the Republic of Singapore Navy's FormidableClass frigates and its upgraded VictoryClass missile corvettes. The earlier Dagaie line was sold to 18 navies worldwide. In its original form, the trainable Dagaie launcher carries 10 "suitcases" containing either chaff (LEM) or IR (LIR) mortar-fired payloads for missile seduction. On the Mk 2 system, the two central "suitcases" were removed and replaced by a pair of threebarrel modules for the REM chaff rocket, which provides chaff blooms in the confusion and distraction modes. The Mk 2 launcher also incorporated a new supervision unit, enhancements to the data processing unit, and adaptations to servo control and power supply units. Lacroix has developed a Dagaie upgrade path, known as Dagaie NG. This replaces the suitcases associated with the LEM and LIR munitions, and instead introduces two six-barrel launcher sets common to the company's Sylena softkill system. Sylena is a fixed, lightweight launcher system designed for small-ship applications. 35
