The Washington Naval Treaty supplied the framework inherited by the 1930 London agreement. Its definition of standard displacement counted a ship complete, manned, equipped, provisioned, and ready for sea while excluding fuel and reserve feed water. The treaty also included a wartime suspension provision and a route to termination after 1936. Small ships received no dedicated treatment, leaving the London treaty to define the exempt-vessel space in which later sloops were designed.

What the Washington Treaty left open
The Washington Naval Treaty defined standard displacement and contained wartime and termination clauses, but said nothing specific about small warships such as sloops.
