A multi-warhead munition includes a first cylindrical warhead having a cavity filled with high explosive, and a second cylindrical warhead offset axially from the first cylindrical warhead. The second cylindrical warhead is a transformable, segmented warhead including a plurality of segments each having an outer segment face bounding a cavity of the segment filled with high explosive. The segments are elongated and mounted at one end for rotation away from an axis of the munition to an open position in which the segment faces are pointed in a forward direction for detonation. Rotation may generally be somewhere in a broad range from about 105 degrees to about 170 degrees, obtaining different effects in different sub-ranges. The munition includes first and second detonators for the first and second cylindrical warheads respectively, the second detonator simultaneously detonating the segments of the second cylindrical warhead.

1. A multi-warhead munition, comprising: a first cylindrical warhead having a cavity filled with high explosive;a second cylindrical warhead offset axially from the first cylindrical warhead, the second cylindrical warhead being a segmented warhead including a plurality of segments, each segment having an outer segment face bounding a cavity of the segment filled with high explosive, the segments being elongated and mounted at one end for rotation away from an axis of the munition to an open position in which the segment faces are pointed in a forward direction for detonation; andfirst and second detonators for the first and second cylindrical warheads respectively, the second detonator being configured and operative to simultaneously detonate the segments of the second cylindrical warhead,wherein the second cylindrical warhead is disposed axially forward of the first cylindrical warhead, and wherein the segments of the second cylindrical warhead are mounted for rotation by a rotation angle greater than 90 degrees toward a focal region at which each of the segment faces is pointed, the focal region located on the axis of the munition at a forward end of the second cylindrical warhead. 2. The multi-warhead munition of claim 1, wherein the rotation angle is in a range between 105 degrees and 170 degrees. 3. The multi-warhead munition of claim 1, wherein the first and second detonators are co-configured to detonate the second cylindrical warhead before the first cylindrical warhead. 4. The multi-warhead munition of claim 1, wherein the second cylindrical warhead is configurable into a plurality of deployment configurations including a folded configuration and an open configuration, the open configuration having the segments rotated away from the axis of the munition by the rotation angle of greater than 90 degrees, the folded configuration having the segments extending parallel to the axis of the munition with the segment faces pointed radially away from the axis of the munition for detonation. 5. The multi-warhead munition of claim 4, wherein the open configuration is a first open configuration and the rotation angle of greater than 90 degrees is a first rotation angle, and wherein the deployment configurations further include a second open configuration having the segments rotated away from the axis of the munition by a second rotation angle of substantially 90 degrees for detonation. 6. The multi-warhead of claim 5, wherein the deployment configurations include two variants of the first open configuration, a first variant having the first and second detonators configured and operative to simultaneously detonate the first cylindrical warhead and the segments of the second cylindrical warhead, the second variant having the first and second detonators configured and operative to detonate the segments of the second cylindrical warhead before detonating the first cylindrical warhead. 7. The multi-warhead munition of claim 1, wherein the segments are rotating segments and the second cylindrical warhead further includes non-rotating segments extending parallel to the axis of the munition with segment faces pointed radially away from the axis of the munition for detonation. 8. The multi-warhead munition of claim 7, wherein the second cylindrical warhead is configurable into a plurality of deployment configurations including first and second configurations, the first configuration having the second detonators configured and operative to detonate the rotating and non-rotating segments simultaneously, the second configuration having the second detonators configured and operative to detonate the rotating segments without detonating the non-rotating segments. 9. The multi-warhead munition of claim 1, further including a nose member to which the segments are hingedly attached for rotation. 10. The multi-warhead munition of claim 9, wherein the segments are spaced from a point of hinged attachment to become spaced from the nose member in the open position to locate the focal region ahead of the nose member. 11. The multi-warhead munition of claim 1, further including a third cylindrical warhead axially displaced from the first and second cylindrical warheads. 12. The multi-warhead munition of claim 11, wherein the second cylindrical warhead is located forward of both the first and third cylindrical warheads. 13. The multi-warhead munition of claim 12, wherein the first cylindrical warhead is a shaped charge warhead located aft of the second cylindrical warhead, and the third cylindrical warhead is a thermobaric warhead located aft of the first cylindrical warhead. 14. The multi-warhead munition of claim 1, wherein each of the segment faces includes a respective elongated liner configured to form a penetrating slug upon detonation of the segment. 15. The multi-warhead munition of claim 1, wherein the segments are linear segments with wedge-shaped cross sections having respective interior apexes facing the axis of the munition when the segments are in a folded, non-rotated position. 16. A method of engaging a target with a multi-warhead munition including a cylindrical shaped charge warhead aft of a cylindrical transformable warhead, comprising: classifying the target as one of an area target, a point-and-area target, a hardened-point-and-area target, and a hardened-point target;selecting a configuration of the transformable warhead based on the classifying of the target, including: selecting a first configuration based on classifying the target as an area target, the first configuration having (1) segments of the transformable warhead in a folded position to generate a hail of fragmentation projectiles radially away from the munition upon detonation, and (2) first and second detonators configured to detonate the shaped charge warhead and transformable warhead simultaneously;selecting a second configuration based on classifying the target as a point-and-area target, the second configuration having (1) segments of the transformable warhead in a first open position to generate a hail of fragmentation projectiles axially forward upon detonation, the segments being rotated away from an axis of the munition to a first rotation angle of substantially 90 degrees to direct respective segment faces in a forward direction, and (2) the first and second detonators configured to detonate the shaped charge warhead and transformable warhead simultaneously;selecting a third configuration based on classifying the target as a hardened-point-and-area target, the third configuration having (1) the segments of the transformable warhead in a second open position to generate a hail of fragmentation projectiles axially forward upon detonation, the segments being rotated away from the axis of the munition to a second rotation angle of greater than 90 degrees to point the segment faces to a focal region ahead of the munition, and (2) the first and second detonators configured to detonate the shaped charge warhead and transformable warhead simultaneously; andselecting a fourth configuration based on classifying the target as a hardened-point target, the fourth configuration having (1) the segments of the transformable warhead in the second open position, and (2) the first and second detonators configured to detonate the shaped charge warhead after detonating the transformable warhead; anddelivering the munition with selected configuration to the target for detonation. 17.
