The ARA Comodoro Rivadavia (Q-11) is a survey ship of the Argentine Navy assigned to the national Hydrographic Naval Service (SHN for Servicio de Hidrografia Naval [1]) which among other things is responsible of the maintenance of nautical charts, balises and lighthouses.


Comodoro Rivadavia was built by Mestrina shipyard in Tigre, Buenos Aires and commissioned into the Argentine Navy in December 1974. She was the second navy ship to be named upon the city of Comodoro Rivadavia which in turn is named after sailor Martín Rivadavia, country's first Navy Minister (charge now succeeded by the Minister of Defense) and grandson of President Bernardino Rivadavia.

The ship is classified as an Hydrographic vessel and equipped with probes and bathymetric sensors.
