NATO STO Centre for Maritime Research and Experimentation (CMRE) crews deploy a WaveGlider during the 2019 Recognised Environmental Picture, Maritime Unmanned Systems (REPMUS19) initiative.
WaveGliders are low-power, long-endurance unmanned surface vessels (USVs). Nominally 3m in length, the WaveGlider takes propulsion energy from ocean waves and the battery recharges from the sun. They travel at 1.5 to 2.25 knots in sea and can tow payloads such as sonar arrays. They have been proven in multi-month deployments, mainly for oceanographic purposes.
