1. A guidable projectile, comprising:

  • a guidable projectile frame having a support structure;

    a set of fins, each fin being pivotally attached to the guidable projectile frame; and

    a deployment assembly to deploy a set of fins relative to the guidable projectile frame, the deployment assembly including;

    an actuator supported by the support structure, the actuator being constructed and arranged to provide an actuator force;

    a first spring-loaded stage supported by the support structure and in operative communication with the actuator, the first spring-loaded stage being constructed and arranged to provide a first spring-loaded output force to a fin restraining element in response to the actuator force from the actuator to move the fin restraining element from a locked position to an unlocked position relative to the set of fins; and

    a second spring-loaded stage supported by the support structure and in operative communication with the first spring-loaded stage, the second spring-loaded stage being constructed and arranged to provide a second spring-loaded output force in response to the first spring-loaded output force from the first spring-loaded stage, the second spring-loaded output force being applied to the set of fins to move the set of fins from an initial non-deployed configuration relative to the support structure to a subsequent deployed configuration relative to the support structure.
