The A27-E is the configuration of ECA Group A27 Autonomous Underwater Vehicle, AUV, family for civil applications. His flexible platform is capable of carrying out missions inthe following domains:

  • Hydrographic data acquisition (compliant with “special order” recommendations of IHO SP44),
  • Oceanographic data gathering (current and temperature profiling, habitat mapping)
  • Geophysics data gathering (sediment analysis, seafloor classification),
  • Shipwreck or crashed underwater aircraft localisation (sonar and video imaging)

This system can be delivered with a LARS allowing automatic underwater recovery and software for data post processing.




  • Full suite of sensors working simultaneously
  • High stability due to design architecture increasing acoustic sensors performance
  • Operation from non-dedicated vessels or coastal platforms
  • Automatic underwater recovery system
  • Easy deployment for overseas missions (ISO containers transportation)
  • User friendly mission management system for mission planning, simulation, monitoring and replay
  • Flexibility of sensors payload
  • Onboard intelligence


  • IHO SP44 compliant


  • Medium water bathymetry: Survey for Hydrography Oceanography
  • Hydro-Oceanography Vessel 
  • Vessels systems & equipment: Hydrographic systems for data acquisition
