The Arabis class was the third class of minesweeping sloops and the largest building project^[2] completed under the Emergency War Programme for the Royal Navy in World War I. They were part of the larger "Flower Class", which were also referred to as the "Cabbage Class", or "Herbaceous Borders". The ships were also used outside of their minesweeping duties as patrol vessels, tugs, and personnel and cargo transports.^[3]

The design for the Arabis class was made at the end of 1914.^[3] All 36 British vessels were ordered in July 1915, and were built in three batches, averaging 12 vessels. A further 8 vessels were later built in British shipyards for the French Navy. The design was highly appealing, as most shipyards were capable of building them, and construction could be completed in five months.

Like the preceding Acacia and Azalea class sloops, these were single-screw Fleet Sweeping Vessels (Sloops) with triple hulls at the bows to give extra protection against loss when working.
