System Description
MN102 - MURENA is a multi-influence sea mine designed to be effective against a wide range
of targets. It is the third generation of S.E.I. sea mines after the well known MR80, MP80/MRP
mines. The mine can be laid by surface vessels, aircraft, submarine (torpedo tube or mine
belts). The mine logic is based on a unique analysis of target acoustic, magnetic and pressure
sensors and offers the operator an incredible flexibility. The precision reached in target
classification and localization make MN102 - MURENA extremely effective against a wide
range of target and resistant against mine countermeasures. Special background noise, depth
and tide compensation guarantees the best target kill probability in any environmental
scenario. The option of a cable remote control increases the flexibility of employ in harbour,
strait and port defence.
