The Tide-class tanker (previously known as the Military Afloat Reach and Sustainability (MARS) project) is a group of four swift fleet tankers that commenced operations with the British Royal Fleet Auxiliary in 2017. These 37,000 t vessels supply fuel, provisions, potable water, munitions, and other resources to Royal Navy vessels globally. Norway ordered a comparable 26,000 t model featuring a 48-bed hospital and increased solid storage capacity, albeit with reduced liquid storage. It was delivered in November 2018 as HNoMS Maud, deviating from the original plan by two years. Although the two variants share similarities, their diverse capabilities make direct comparison challenging.

Both variations are derived from the AEGIR design by Britain's BMT Defence Services but were constructed by Daewoo in South Korea, undergoing final fittings in the UK and Norway, respectively. The UK initially ordered four ships in February 2012, budgeted at £452m for hull construction, which eventually escalated to £550m.

The Norwegian Navy procured HNoMS Maud in June 2013 for £140m. The order placed on February 22, 2012, for four tankers at Daewoo stood at £452m, with an additional £150m allocated for UK expenditure, totaling slightly over £600 million for all four vessels. The decision to build in South Korea stirred controversy in Britain as no British yards bid for the contract. Eventually, the new class revived names from the Cold War Tide-class oilers — Tidespring (A136), Tiderace (A137), Tidesurge (A138), and the new name Tideforce (A139).

The Tide class, measuring 200.9 m (659 ft 1 in) and weighing 39,000 t, stems from BMT Defence Services' AEGIR-26 design. Its inception traces back to a civilian tanker from Norway's Skipskonsulent. These ships boast double hulls to minimize oil loss due to outer hull damage, aligning with MARPOL regulations for civilian tankers (partially applicable to military tankers). This design not only enhances safety but also allows access to areas discouraged for their single-hulled predecessors.

Equipped with three replenishment at sea (RAS) stations for diesel oil, aviation fuel, fresh water, and a rig for astern replenishment, the Tide class facilitates diverse replenishment methods. The flight deck accommodates helicopter replenishment (vertical RAS) and can handle a Chinook landing. Propulsion relies on medium-speed diesel engines in a hybrid CODELOD setup for fuel efficiency across speed ranges.

Each ship can be armed with two 30 mm cannons and two Phalanx CIWS. Usually, heavy armaments are installed only during high-risk deployments, aligning with RFA vessels' standard policy. For instance, as of June 2021, RFA Tidespring is outfitted with fore and aft Phalanx CIWS fixtures and both 30 mm cannons during its global deployment with CSG21.
