Kongsberg Maritime launched the Kongsberg Seaglider™ AUV at AUVSI 2013. This AUV is a low-cost device, with long endurance, and capable of deployment durations in excess of nine months. The technology uses changes in buoyancy for thrust, combined with an extremely hydrodynamic shape resulting in low-energy requirements, hence its ability to partake in much longer missions than propeller-driven AUVs. Full production of the AUV is expected by December 2013, although there is capacity for delivery of special orders before this date. www.km.kongsberg.com
