The contract worth 707 million for the supply of 4 tankers of this type was concluded with the South Korean company Daewoo Shipbuilding and Marine Engineering in March 2012. They are built at the shipyard in Okpo by the project of the ship AEGIR of the British company BMT Defense Services. Equipping the tanker with additional equipment, communications equipment and means of self-defense is carried out already in Britain.
The lead ship Tidespring was launched in July 2014. It was originally expected to be handed over in October 2015, the delivery of the remaining three representatives of the project - until April 2017. The presence of technical problems and the protracted certification have significantly shifted the deadlines for the implementation of the program. The Tidespring will be handed over to the British military only at the end of the 2017 of the year.
