Design and construction The Azalea class was based on the previous , but with a heavier gun armament. They were designed at the start of the First World War as relatively fast minesweepers that could also carry out various miscellaneous duties in support of the fleet such as acting as dispatch vessels or carrying out towing operations, but as the war continued and the threat from German submarines grew, became increasingly involved in anti-submarine duties.

She was launched on 7 October 1915, and was completed on 3 December 1915. Career Snowdrop joined the 1st Sloop Flotilla, operating under the Vice Admiral Commanding, Coast of Ireland, following commissioning. In March 1916, Snowdrop was employed on escort duties. On 29 March, the sloop was torpedoed by the German submarine , and Snowdrop and sister ship were ordered to go to Begonias assistance. Begonia was towed to Queenstown (now Cobh).
