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 are tasked with providing ammunition, fuel, food and other supplies to Royal Australian Navy vessels around the world. There are two ships in the class, Supply and Stalwart.^[2] 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 Cantabria, which entered service in 2011.^[3]
