An elongate cylindrical projectile including processing circuitry, a head assembly, a tail section assembly, a mid body section positioned between the head assembly and tail assembly, and a wing assembly, the wing assembly including a deployable wing which is stored in a closed position entirely within the mid body section and is deployed, using an actuator, to outside the mid body section in an open position in response to a command from the processing circuitry.

A munition including: a control surface actuation device including: an actuator having two or more pistons, each of the pistons being movable between an extended and retracted position, the retracted position resulting from an activation of each of the two or more pistons; and a movable rack having a pocket corresponding to each of the two or more pistons, each pocket being engageable with a corresponding portion of each of the two or more pistons, a distance between the pockets being different than a distance between the portions of the two or more pistons, such that activation of the portion into the corresponding pocket sequentially translates the rack; and a control surface operatively connected to the rack such that translation of the rack rotates the control surface.

A projectile and deployment method ensures successful deployment of the projectile regardless of an external environment. Contacting engagement is maintained between a piston and deployable fins as the fins rotate from a folded position to a deployed position. The fins are pushed by the piston to rotate into a deployed position in which the fins are locked before the piston is able to eject from the assembly. Using the engaging tabs between the fins and the piston, and a modular pressure reservoir, the piston continues to push on the fins at least until the fins are deployed and locked. After locking, pressure in the projectile is equalized and the piston is launched off of the pressure reservoir. If the fins are not immediately deployed and locked, the piston will continue to push on the fins until the external environment enables full deployment or until the pressure is equalized.

A guided projectile includes a body and a deployable wing in which the deployable wing is coupled to and enclosed by the body. A linear distance from the leading edge to the trailing edge of the wing defines a chord line that, in the stowed position, forms an angle with a plane containing the chord line and extending parallel to a longitudinal dimension of the wing in a deployed position.

A munition including: a casing having a first portion and the second portion; and an actuator comprising two or more pistons, each of the pistons being connected at a first end to the first portion of the casing and engaged at a second end to the second portion of the casing, each of the pistons being capable of having an extended and retracted position relative to the first and second ends, the retracted position resulting from an activation of each of the two or more pistons; wherein activation of one or more of the two or more pistons moves the first portion relative to the second portion.
