# 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 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. 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.

## Planning

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. 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 service entry in April 2021.
The second ship, Stalwart, departed for Australia in May 2021 and arrived in late June.

## Operational history

HMAS Supply commissioned at Fleet Base East on 10 April 2021.
HMAS Stalwart commissioned at Fleet Base West on 13 November 2021.

### Mechanical defects

In March 2023, a mechanical defect relating to the shaft alignment was found on HMAS Supply. The ship returned to Garden Island where it was to be repaired by Navantia under warranty.
In June 2024, it was reported that HMAS Supply could remain out of service for another year despite being sidelined for repairs over 14 months previously. In the same month, it was reported that HMAS Stalwart had been sidelined due to mechanical problems relating to its engine. As a result, the Royal Australian Navy currently has no operational replenishment oilers as of 2024. The vessels were anticipated to remain out of service until 2025.
