Supply-class replenishment oiler

The Supply class is a planned class of replenishment oilers of the Royal Australian Navy, a role that combines the missions of a tanker and stores supply ship. As such they are designated auxiliary oiler replenisher (AOR). They will be tasked with providing ammunition, fuel, food and other supplies to Royal Australian Navy vessels around the world. There will be two ships in the class, Supply and Stalwart.[1] The project is expected to cost anywhere between $1 and $2 billion. Navantia were selected to build a design based on the Spanish Navy's current replenishment vessel the Cantabria, which entered service in 2011.[2]

A number of designs were considered by the Australian Government for their replacement tankers, with Navantia competing against the Aegir variant of the Tide-class tanker built by South Korea's DSME in a restricted tender competition.[3][4] 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 of late 2019.[5]


The class of ships based on Navantia's replenishment oiler will be built at the Navantia shipyard in Ferrol, Spain.
