This became effective during 1918.
The paper on Naval Air Policy showed the aim of the Admiralty to be: To provide in sufficient numbers a type of airship which would be able to scout with the Grand Fleet, and, in this respect, to perform the duty of light cruisers.

Airship stations had been established on the East Coast for this purpose.
To provide also a type of airship for coastal patrol work and for the escort of merchant ships in convoy.

For these airships stations had been established on the East, South and West Coasts and at Scapa.
To provide a sufficient supply of kite balloons for the work of the Grand Fleet.

Fleet kite balloon stations had already been established at Rosyth and Scapa, and the resources of the latter station were supplemented by a kite balloon ship.

It was intended also to provide kite balloons for flotillas or single vessels engaged in submarine hunting or in convoy work.
