NGDS allows a rapid response to current and new threats using the means best-suited to the situation. Its versatile single or dual decoy launcher, depending on the tonnage of the vessel, includes infrared, radar or acoustic munitions. NGDS is integrated into the existing combat system and offers a perfect combination of effectiveness and robustness, while offering the best cost-/performance ratio. This technology is used in particular on the French Navy's FREMM frigates.
