'FD' (ii) was the designation of Allied military ferry convoys (together with a numerical suffix) plying the route from the Færoe islands group to the Clyde river, and as such reciprocals of the 'DF' series (March 1943).

The sole known example is FD.3 of 4/8 March 1943 with the 4,303-ton Leinster carrying 857 returning garrison troops and nine other passengers.
