Ship project history: Standard Admiralty coastal design built for comparison with the 'S', 'V and 'W' types. Like them had double-hull features, and was based largely on the 'V' design, with improvements such as a stern TT. The Admiralty was most anxious to encourage the building of diesel engines, and so while F1 had the standard Vickers type, F 2 had 6-cyl Nuremberg (MAN) type built under licence by J Samuel White, but F3 reverted to the Vickers type. The battery had 12S Exide cells. F1 was ordered under the 1913-14 Programme and laid down in January 1913. F2 and F3 came under the 1914-15 Programme. Another three, F4-6 were projected in 1914 but cancelled after war broke out. Being very small these submarines saw relatively little service, apart from local defence.

Modernizations: None.

Naval service: No significant events.
