'SNF' was the designation of Allied fast troopship convoys (together with a numerical suffix) plying the route from Salerno and Naples, Italy, to North African ports after 'Avalanche' and during subsequent Italian operations, and as such reciprocals of the 'NSF' series (September 1943/November 1944).
