These ships are fast fleet tankers capable of replenishment at sea of warships, and with the ability to meet future fuel requirements plus provide a platform for future helicopters.

They are electric ships - which means they are driven by an electric motor, powered by diesel generators - and take advantage of the latest propulsion control technology.

A double-hulled design helps to prevent pollution should the outer hull sustain damage.  Their cargo will be mainly Petroleum, Oil and Lubricants (POL) and they replace the O Class ships, Olna and Olwen.

The vessels have been built to commercial standards with military requirements incorporated where necessary. The contract was placed with what was then Vickers Shipbuilding and Engineering Ltd (VSEL), now part of BAE Systems Marine Ltd, in March 1997.
