Design and construction

''Cantabria'' is a replenishment oiler, referred to in Spanish as a ''Buque de Aprovisionamiento en Combate'' (''BAC''; Supply Ship in Combat). She was acquired to provide logistical support to the Spanish Navy during day-to-day operations, expeditionary forces or strategic projection deployments, and for humanitarian and disaster relief operations. The vessel has a displacement of 19,500 tons, is in length, has a beam of , and a draught of . Propulsion is provided by two diesel engines, supplying to a single propeller shaft, which is fitted with a controllable-pitch propeller. ''Cantabria'' has a maximum sustained speed of , and a range of . The ship's complement is 122.

The ship's capacity includes of ship fuel, of JP-5 jet fuel, of fresh water, 280 tons of ammunition, and 470 tons of general cargo. The fuel storage areas are double-hulled. ''Cantabria'' can replenish three ships simultaneously; one on each side, plus a third via a stern refueling station. She can carry three Agusta-Bell AB.212, two Sikorsky SH-3 Sea King, or two NHIndustries NH90 helicopters to perform vertical replenishment.

''Cantabria'' was laid down in the dry dock of shipyard of Puerto Real, Cadiz, on 18 July 2007; the first ship to be built there in 30 years. The ship was launched by floating on 21 July 2008, and was sponsored by Aurora Diaz Abella, the wife of Miguel Ángel Revilla, the President of the Autonomous Community of Cantabria. The ship underwent sea trials in the Bay of Cadiz from October to December 2009. She was commissioned into the Spanish Navy on 29 September 2010. The original budget was €213m but the final cost was €238m.

Export

The design has been evaluated by foreign buyers. Canada approached Navantia to provide a design for the Joint Support Ship Project based on ''Cantabria'', but Navantia's proposal was not successful, with Canada eventually selecting an alternative German design based on the . The Norwegian Navy has also expressed interest, but they have announced an order for a replenishment ship from South Korean shipbuilder DSME.

Australia considered the design for their replacement tankers, with Navantia competing against the Aegir variant of the built by South Korea's DSME in a restricted tender competition.
Navantia's proposal based on ''Cantabria'' was announced as the successful design in the Australian tender in March 2016, with an expected in service date for the first of two vessels to be known as HMA Ships ''Supply'' and ''Stalwart'' of late 2019. The two vessels will be known within the Royal Australian Navy as the ''Supply'' class.

Operational history

Between 2 and 5 July 2012, ''Cantabria'' participated alongside the frigates , , and , the submarine , and AV-8Bs of the 9th naval air squadron during exercise MAR-22 on the Atlantic coast of Galicia.

On 3 July 2012, the Australian and Spanish governments signed an agreement to deploy ''Cantabria'' in support of the Royal Australian Navy during 2013. The ship operated in Australian waters from February to November 2013, was used to provide replenishment support to the Australians while the oiler underwent maintenance. While in Australian waters, ''Cantabria'' performed 63 replenishments, including of fuel, was involved in the first vertical replenishment of an by an MRH-90 helicopter, and participated in the International Fleet Review 2013. The deployment also allowed over 300 Australian personnel to train on systems similar to those in the Spanish-designed and -class ships being acquired, and allowed the Royal Australian Navy to evaluate the design as a possible replacement for its replenishment vessels.

In 2015 the Canadian and Spanish governments concluded a deal where and ''Cantabria'' would deploy with Canadian naval forces as their replenishment vessel in 2016. This would be done primarily for training missions. ''Cantabria'' would be made available to the Royal Canadian Navy from mid-September to November 2016.
