After World War I, the Royal Navy still had a global empire to protect while trying to rebuild institutional confidence after Jutland. Interwar treaty rules generally left ships below 2,000 tons unlimited if they stayed below 20 knots and carried no torpedoes. That exemption gave the service room to maintain global station forces without consuming cruiser or destroyer allowances. The resulting vessels could become survey ships, minesweepers, minelayers, escorts, or anti-submarine specialists as regional requirements changed. Flower-class experience therefore supplied a modern replacement for the elderly hulls once used on station and showed how one basic platform could support many peacetime and wartime roles.

Interwar treaties left sub-2,000-ton, sub-20-knot, non-torpedo ships largely unlimited, letting the Royal Navy preserve flexible station forces.
