The LABUST origins can be traced back to late 1960s when the research group was formed at the University of Zagreb Faculty of Electrical Engineering (UNIZG-FER) and at the association of shipbuilding industry „Jadranbrod“ in Zagreb. In the 1970s and 1980s cooperation with the Brodarski Institute in Zagreb, Shipyard „Uljanik“ in Pula, and Central Research Institute of Marine Fleet in Leningrad was intense. Main topics of R&D at that time were navigation, guidance, and control (NGC) of ships and submarines. In 1990s our focus diversified toward unmanned marine vehicles. In that time we operated as a research group at UNIZG-FER, to be finally established as research laboratory LABUST in December 2011, when the legislation at the UNIZG-FER allowed founding of research laboratories. The research staff changed over the years to reach the number of 10 researchers in 2016. LABUST is at present the only research laboratory with R&D and innovation capabilities for underwater systems and technologies on the east coast of the Adriatic Sea! We are proud to be able to maintain expertise in this domain in Croatia, against all odds.
