The state-of-the-art design and use of composite materials is meant to give the missile sophisticated stealth capabilities. The missile will weigh slightly more than 400 kg (880 lb) and have a range of at least 185 km (100 nm). NSM is designed for littoral waters ("brown water") as well as for open sea ("green and blue water") scenarios. The usage of a high strength titanium alloy blast/fragmentation warhead from TDW is in line with the modern lightweight design and features insensitive high-explosive II. Warhead initiation is by a void-sensing Programmable Intelligent Multi-Purpose Fuze designed to optimise effect against hard targets.
