The Littoral Continuous Active Sonar Multi-National Joint Research Project 2014–2020

One of John Preston's achievements during his career was the hosting of multinational sonar experimentation efforts whilst a scientist at SACLANTCEN. The Littoral Continuous Active Sonar Multi-National Joint Research Project is the most recent international collaborative experimentation activity focused on sonar hosted by NATO STO Centre for Maritime Research and Experimentation, SACLANTCEN's sucessor. Between 2014 and 2020 LCAS brought scientists and engineers from 7 NATO and Partner Nations together with the CMRE to evaluate the effectiveness of continuous active sonar in shallow littoral environments. In this talk, the objectives of the project are laid out, the scientific issues and experimental approach reviewed, details about the four sea trials conducted under LCAS are presented, and a summary of the major results of the project is provided.
