The REP(MUS)19 is an exercise that takes place annually

since 2010 in the south of continental Portugal. LSTS (Underwater Systems and Technology Laboratory) has co-organized these events, since the beginning, together with the Portuguese Navy and, in more recent years, with NATO-CMRE. NATO’s MUS (Maritime Unmanned Systems Initiative) initiative joined the event in 2019. The target of these exercises is to have technological experimentation activities that engage armed forces, universities, and industry, in the unmanned system’s operation. The event operational environment enables interactions between all parties to share experiences and needs to drive research in the direction of real-life needs. LSTS’ participation in the 2019 event consisted of eight exercises.
