The mid-frequency scattering properties of three different cylindrical shell models have been evaluated experimentally to study the influence of resiliently mounted internal structures and typical structural discontinuities such as endcaps and transverse stiffeners. The models consist of an empty shell, and unequally spaced ring-stiffened shell, and a ring-stiffened shell with resiliently mounted, wave-bearing internal structural elements. The measurements were conducted over a frequency range of 2.75
