About

CUIIS is a defense system integrator based in Sofia, Bulgaria working in unmanned systems, c4isr, communications & satcom +1 more.

CUIIS (Comprehensive Underwater Intervention Information System) is a European Defence Industrial Development Programme (EDIDP) project, funded under grant agreement EDIDP-UCCRS-EDD-2020-059. It is carried out by a consortium of 18 organisations from 7 EU countries, including industry SMEs and mid-caps, military and civil academic institutions, and research bodies. The project aims to develop next-generation comprehensive underwater solutions for enhanced defence diving, to detect, identify, counter and protect against sub-surface threats. Its scope covers physical support and recovery of divers, C4I mission systems for underwater management, underwater monitoring, situational awareness, positioning, navigation, and manned-unmanned teaming. The system is to be developed incrementally over three years and tested and assessed in demonstration phases. The project coordinator and WP1 leader is BDI, the Bulgarian Defence Institute in Sofia. Kick-off took place in January 2022 at the Professor Tsvetan Lazarov Defence Institute in Sofia.
