The body is a welded cylin¬drical ease closed at each end by a cover which is welded on. The central primer tube is welded into an opening in the rear cover, and exte3ids approximately half way through the body. Equi-spaced around the rear cover are three lugs, each drilled and tapped to receive a stud used for securing the tail to the depth charge. Two filling holes, each closed hy a bung, arc provided in the rear cover. The front cover is dished in¬ward to prevent ricochet.

The front of the tail has one large port for the fuze-setting control link, and two small ports to give access to pistol and valve unit when fitting the fuze-setting control link. The Tail Mk IV is designed with arming vanes and a reach rod to arm Pistols Mks XIX and XX, which are of the air-arming type and are re placing the Tail Hydrostatic Pistols Mks XIV and XVI, This tail is constructed with a three-segment cone, to which arc riveted three fins supporting the three-segment cylindrical strut.
