Although unmanned underwater vehicles (UUVs) had initially existed for marine exploration, research, search and rescue since the late 1950s, they became more common when they begun to be utilized for mine countermeasure (MCM) missions. Along with the proliferation of autonomous and remotely controlled systems, navies keep their personnel away from a risky and dangerous environment, so this approach is whipping up investments in unmanned maritime technology. Today's UUVs offer an improvement in operation time and safety, greater flexibility of use, more efficient power systems, and lower implementation and sustainability costs.
