1. A ballistically actuated plug for being deployed in a wellbore casing, comprising:
a ballistic housing comprising a first housing portion including a chamber, and a second housing portion having a noncompressible core;
an initiator positioned within the chamber;
a detonation extender in ballistic communication with the initiator and circumferentially disposed around the noncompressible core;
an outer seal housing circumferentially disposed around the noncompressible core, and
a recess formed in an outer surface of the second housing portion;
a first sealing mechanism positioned around the outer surface of the second housing portion; and
a second sealing mechanism positioned around the outer surface of the second housing portion;
wherein the detonation extender is configured, upon detonation, to expand the outer seal housing from an unexpanded form to an expanded form to secure the outer seal housing within the wellbore casing;
the recess is configured to receive the detonation extender;
the recess extends between the first sealing mechanism and the second sealing mechanism; and
the first sealing mechanism and the second sealing mechanism are both spaced apart from the recess.
