[4] A further five Folders (119–122, 186), powered by 160 hp Gnomes were delivered in 1914, with longer fuselages and larger three-bay wings of 67-foot (20.4 m) span compared with 56 feet (17.1 m) for the first aircraft).

[5] The RNAS took delivery of 81 on 17 July 1913, and it was quickly deployed aboard the cruiser HMS Hermes, which had been converted to the first seaplane tender of the Royal Navy, for the 1913 Naval manoeuvres, where it was used for reconnaissance missions, using a radio set to report the position of shipping.

[2] An engine failure on 1 August resulted in 81 ditching about 50 miles from Great Yarmouth, but although damaged, it was rescued by the German timber carrier Clara Mennig.

[6][7] The second aircraft 82 took place in the unsuccessful search for the missing submarine HMS A7,[7] while four 160 hp Folders took part in the Spithead Fleet Review in July 1914.

[14] Following the outbreak of the First World War in August 1914, the Royal Navy purchased three fast cross-channel ferrys for use as seaplane carriers, one of which was HMS Engadine, to which three 160 hp folders were allocated.
