She has a bulk cargo capacity of 9,856 m3 or 6,300 tons (e.g.: coal, cereals, live cattle), and can carry up to 140 containers.

Bahía San Blas is powered by two 6-cylinder Sulzer 6 ZL 40/48 marine diesel engines of 3200 hp each, driving two variable-pitch propellers; with a maximum speed of 16.5 kn.

History
The ship is a Costa Sur-class cargo ship vessel built at Astilleros Príncipe, Menghi y Penco at Buenos Aires in 1978 entering service on November of that year in the Transport Maritime service of the Argentine Navy. The other ships of the class are ARA Canal Beagle and ARA Cabo de Hornos.

In 1991 she was deployed to the Persian Gulf during operations Desert Shield and Desert Storm carrying humanitarian aid and providing logistic support to the Argentine warships in the area.

In 1992 Bahía San Blas transported back from the Gulf of Fonseca the four Baradero-class patrol boats used under United Nations mandate ONUCA.

After the retirement of ARA Cabo San Antonio, Bahía San Blas became the main vessel for use by the Argentine Marines receiving several modifications.

Since 2004, an Argentine contingent was deployed to Haiti under MINUSTAH mandate and Bahía San Blas has been used for logistic support making several voyages to the Caribbean island.

As of late 2016, Bahía San Blas remains in service with the Argentine Navy.
