The craft entered service in the Spanish Navy in February 2014 and was homeported at the ‘Puntales’ Naval Station. The following month the ‘Sondaleza’ was assigned to the craft unit of the Spanish Navy Hydrographic Institute.

Its main mission is to conduct hydrographic surveys in ports, approaches and anchorages. In addition, the vessel can also carry out the following missions:

• Search and pinpoint wreckages and underwater pipelines.
• Examine and check nautical charts, sea lines, annual directories of tides, lighthouses’ books, coast lines, buoys positioning, and any other hydrographic control issues.
• Installation of tide gauges to determine the hydrographic zero.
• Collection of data related to port communications, pilotage, shipping control devices, wreckages, submarine emissions and fish farms.
