A Rocky Mountain-class fleet replenishment oiler.
The Rocky Mountain-class Fleet Replenishment Oiler is a large class of auxiliary vessel in service the Canadian Forces Maritime Command from 2003 onwards built to replace the aging Provider and Protecteur-class fleet replenishment oilers. Originally there were only five vessels planned, however in the mid-2010s, another five Rocky Mountain-class oilers were planned for construction after the Titan-class fleet supertankers were commissioned.

The vessel design was a 840-foot-long double-hulled vessel, which had three bunkers - two for marine diesel and one for aviation fuel, though all three could be used for marine diesel if needed - which had four refueling rigs and a large helipad on the end of the vessel. Four loading cranes also were installed, and the vessel could also carry 155 20-foot containers of the same design as used by the Canadian Forces. The vessel, which also could serve as a command center and mad many advanced features, was powered by eight geared General Motors Model 265 turbodiesel engines, giving the 52,000-ton vessel a maximum speed of some 24 knots (44.45 km/h), faster than the Provider and Protecteur-class vessels.

The design, which would called the Rocky Mountain-class, was approved by parliament on November 14th, 2000. The first was laid down on January 10th, 2001, at the MIL Davie Shipyards in Lauzon, Quebec.

In the late-2010s, Canada ordered a further five Rocky Mountain-class replenishment oilers.
