Lightweight anti-submarine weapon
The MU90/IMPACT torpedo is 323,7mm 'NATO Standard' calibre, weight 304 Kg and is 2850 mm long. Powered through an Aluminium-Silver Oxide sea water battery using dissolved sodium-dioxide powder as electrolyte and incorporating an advanced closed-loop electrolyte re-circulation system, the torpedo is propelled by an electronically controlled high-RPM brush-less motor driving a skewed multi-blades pump-jet propulsor allowing a linearly variable torpedo speed automatically selected by the tactics of the weapon according to the scenario, the environment and the operational phase. Of extremely long endurance, the weapon operates without any speed degradation and without any limitation of salinity and temperature in water depths in excess of 1000 m and as shallow as 25 m and retaining navigation capability up to 3m.
