A body spin detection device for a projectile, the device including a perturbing element and a detection element electrically connected to detection circuitry in the projectile. The detection circuitry configured to receive, via the detection element, a first and second input signals and determine that the first input signal is different from the second input signal based on signal characteristics for the first and second input signals. The detection circuitry is further configured to determine a spin rate for at least one of the despun control portion and the chassis by determining a time period between receiving the first input signal and the second input signal.

A projectile including an ejectable aft fin housing assembly. The aft fin housing assembly includes aft fins that increase a distance between a center of gravity and a center of pressure of the projectile, improving passive stabilization of the projectile. Once the projectile has been passively stabilized, the aft fin housing assembly is ejected, decreasing a distance between the center of gravity and the center of pressure, improving active stabilization of the projectile.

A projectile and method of deploying a projectile includes a wing deployment system for deploying a wing of a projectile. The wing deployment system includes a stored energy release mechanism that is activated to generate an initial range of motion of the wing and a panel arranged on the wing and configured to cause an angular acceleration of the wing during the initial range of motion of the wing.

An effector having an extendible range and a method for extending the range of an effector includes using an axially translatable center body that is movable from a stowed position, in which the center body is stowed in an outer body of the effector, to a deployed position in which the center body extends out of the outer body to extend the axial length of the effector. The effector includes a ramjet assembly and the subsystems of the effector are contained in the center body. The movement of the center body exposes radially positioned ramjet fuel in the outer body, such that the air entering the ramjet inlet may be heated by combusting the air with the fuel for additional fuel and propulsion of the effector.
