Supply-class replenishment oiler

The "Supply" class is a 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, and . 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 , which entered service in 2011.
Planning.
A number of designs were considered by the Australian Government 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 of late 2019.
Construction.
The class of ships based on Navantia's replenishment oiler were built at the Navantia shipyard in Ferrol, Spain. The first ship, "Supply", arrived at Fleet Base West in October 2020 to begin fitting Australia-specific equipment prior to her envisaged service entry in 2021.
