A containment for a gas turbine engine, the containment comprising: a plurality of acoustic panels angularly arranged around a central longitudinal axis of the containment, each forming part of an annular acoustic liner. Each acoustic panel comprises: a core of cellular material comprising a plurality of elongate cells which are elongate along respective cell directions, wherein each of the elongate cells is circumferentially inclined relative to a local radial direction such that the cell direction has a circumferential component and a radial component relative to the central longitudinal axis; at least one axially-extending panel side wall which is circumferentially inclined relative to a local radial direction such that, in a plane normal to the central longitudinal axis, the panel side wall has a circumferential component and a radial component. Each acoustic panel radially overlaps with another at adjacent panel side walls, with respect to a local radial direction extending through the adjacent panel side walls. Accordingly each acoustic panel is removable from between adjacent overlapping acoustic panels along a removal path which has substantially no axial component.
