Abstract: Embodiments described herein provide apparatus and method for stand-off deployment of UUVs utilizing self-directed projectiles that include guidance kits. One embodiment is a projectile that includes a guidance kit that directs the projectile in flight. The projectile further includes a shell and a hollow nose cone. The shell mates with the guidance kit and the nose cone couples with the shell. The nose cone includes an interior surface configured to house a UUV. The projectile further includes a controller that identifies a condition for deploying the UUV in flight, and detaches the nose cone from the shell in response to determining that the condition is satisfied.
