The First Fleet was a formation of the Royal Navy that briefly existed before the First World War from 1912 to 1914.
The First Fleet was formed on 31 July 1912, with the Commander-in-Chief Home Fleets in direct command of it; [1] a vice admiral commanded the Second and Third Fleets. The numbered fleets during this period had different levels of battle readiness; ships of the First Fleet ships were in full commission. [2]
