The 1930 London Naval Treaty mattered to sloops because Article 8 exempted certain small vessels from limitation while restricting what they could carry or do. The 600- to 2,000-ton range came with limits on heavy guns, torpedoes, speed, armour, mines, and aircraft facilities. These rules kept a nominal sloop from becoming a disguised destroyer or miniature cruiser while leaving room for useful fleet-support and overseas vessels. This was the legal and design context for the interwar classes that followed.
