A projectile (100) with incidence steerable control surfaces (2) each pivotable with respect to the projectile (100), comprises: central control means (5) for controlling the control surfaces (2), a control arm (11) adapted to rotate the central control means (5) around pitch (Y) and yaw (Z) axes of the projectile (100), positioning means for positioning the arm (11), adapted to position one end of the arm (11) in a position determined with respect to an absolute reference frame, the positioning means comprising a cone (13) movable in translation so as to pivot the central control means around an orientation axis (AO), and a toothed wheel (16) meshing with a motorization intended to pilot the angular position of the orientation axis in an absolute reference frame.

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 control surface actuation device including: an actuator comprising 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 rotatable plate 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 rotates the plate; and a control surface operatively connected to the plate such that rotation of the plate rotates the control surface.

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 lock block for use in a flight vehicle to deploy and lock wings in a deployed position with the lock block having a forward end and an aft end and including a support member, a resilient member adjacent the aft end of the lock block, a first deploy pin extending from the resilient member, a second deploy pin extending from the resilient member, and a wedge located on a bottom side of the resilient member. The first deploy pin and the second deploy pin are each configured to engage a groove in a wing of the flight vehicle to push each wing into a deployed position.
