A warhead casing includes a nose region, a tail region, a tubular body region, and a central cavity extending along a lengthwise axis and having a first axial end and a second axial end. An aft wall is formed integrally with the tail region and extends radially toward the lengthwise axis to define the second end of the central cavity, and includes an aperture configured to receive a fuse device. A method of manufacturing a warhead casing includes forming a nose portion, a body portion, and a tail portion. The tail portion includes a circumferential outer wall defining an inner cavity, and an aft wall integrally formed with the circumferential outer wall and extending radially inward to define an axial end of the inner cavity. At least one of the nose portion or the tail portion is joined to the body portion.

1. A warhead casing, comprising: a nose region, a tail region, and a tubular body region therebetween, the regions defining a lengthwise axis of the casing;a central cavity extending along the lengthwise axis and having a first axial end and a second axial end, the central cavity having a diameter and being defined within circumferential outer walls of the nose, tail, and tubular body regions;an aft wall formed integrally with the tail region and extending radially toward the lengthwise axis to define the second end of the central cavity, whereby the aft wall remains integral with the tail portion when the casing expands radially upon impact and before detonation, the aft wall including an aperture configured to receive a fuse device and extending axially through the aft wall, the aperture having a diameter that is no more than half the diameter of the central cavity in the tail region. 2. The warhead casing of claim 1, further comprising: a socket formed in an outer wall of the tail region and substantially aligned with the aft wall along the lengthwise axis, the socket configured to receive a sensor device. 3. A warhead casing, comprising: a nose region, a tail region, and a tubular body region therebetween, the regions defining a lengthwise axis of the casing;a central cavity extending along the lengthwise axis and having a first axial end and a second axial end;an aft wall formed integrally with the tail region and extending radially toward the lengthwise axis to define the second end of the central cavity, the aft wall including an aperture configured to receive a fuse device; anda passageway extending radially through the aft wall between the socket and the aperture, the passageway configured to receive a cable for connecting the sensor device to the fuse device. 4. The warhead casing of claim 3, wherein the passageway includes a first branch and a second branch separate from the first branch, the first branch configured to receive the cable for connecting to a first portion of the fuse device, and the second branch configured to receive the cable for connecting to a second portion of the fuse device. 5. The warhead casing of claim 1, wherein the tubular body region is symmetric about the lengthwise axis. 6. The warhead casing of claim 1, wherein the tubular body region is continuous about the lengthwise axis such that the casing does not include an aperture extending from an outer periphery of the tubular body region into the central cavity. 7. The warhead casing of claim 1, wherein the casing is monolithic. 8. A method of manufacturing a warhead casing, comprising the steps of: independently forming a nose portion, a body portion, and a tail portion, including forming the tail portion with a circumferential outer wall defining an inner cavity and an aft wall integrally formed with the circumferential outer wall and extending radially inward to define an axial end of the inner cavity, the aft wall including an aperture extending therethrough smaller in diameter than the inner cavity and configured to receive a fuse device;permanently joining the nose portion to a first end of the body portion by welding;processing a first internal connection area between the nose portion and the body portion to remove irregularities caused by welding and create a smooth and continuous inner surface, accessing the first internal connection area through an open second end of the body portion;permanently joining the second end of the body portion to the tail portion by welding;processing a second internal connection area between the body portion and the tail portion to remove irregularities caused by welding and create a smooth and continuous inner surface, accessing the second internal connection area through the aft wall aperture. 9. The method of claim 8, wherein forming the tail portion includes forming a socket in the circumferential outer wall, the socket substantially aligned with the aft wall and configured to receive a sensor device.
