HMS Umpire (1917)

HMS Umpire was a U-class submarine built for the Royal Navy during World War I. She was ordered in July 1916 and built by Armstrong Whitworth at their Newcastle upon Tyne shipyard. Launched on 27 January 1917, she was commissioned into service later that year.

As a U-class submarine, Umpire was primarily designed for coastal patrol and anti-submarine warfare. Details regarding her specific operational deployments and successes during World War I are scarce, as records for many submarines of this era are incomplete. However, she would have likely participated in patrols within the North Sea and potentially other areas around the British Isles, targeting German U-boats and surface vessels.

After the war, Umpire remained in service with the Royal Navy for a number of years before eventually being scrapped. The precise date of her decommissioning and disposal is not readily available in commonly accessible historical records. Her service reflects the significant contribution of the U-class submarines to the Allied war effort.
