As part of the military afloat reach and sustainability program (MARS) there is a requirement to replace the royal fleet auxiliary replenishment at sea (RAS) fleet. Studies have shown for a large navy, separating the fuel and solid supply ships its the most efficient method, rather than the mixed approach seen in the past. The first part of the program is the Tide Class Tanker, which are under construction now. The second part of the program is the solid support ship which will be separate to the tanker, under a different class name (although currently unnamed).
The Solid Support Ship will be vitally important to the navy, particularly the carriers which will require a purpose built system to fill its big logistical footprint in the most efficient way possible. I think we can expect some more news in this years SDSR and hopefully the program can start once the tide class are built. I think the tide class seems to be coming along remarkably well so it would seem reasonable that the Solid Support Ship will follow a similar program.

The image above is from a BMT study into the optimal layout. Things to note are the large vehicle deck, steel beach, and large hanger. This design is for mixed use but its easy to see how the fuel cargo tanks can be replaced.
as always Gabriele has some great information on the project: http://ukarmedforcescommentary.blogspot ... -ship.html
