A tail for a projectile includes a body having a longitudinal axis. A steering assembly is secured to the body. The steering assembly includes a flap movable from a first position in which the flap does not extend radially beyond the body to a second position in which the flap extends radially beyond the body and at an angle relative to the longitudinal axis, and a flap release mechanism. A projectile including a tail according to the present disclosure is also provided.

Deployable flap for high-G maneuvers

An electronic circuit is made by selectively depositing an electrically conductive material seed layer conformally upon a three-dimensional substrate via the plurality of apertures of a three-dimensional mask. The substrate is then plated with more of the same electrically conductive material, or a different electrically conductive material, on the seed layer. In the case of electroplating, a nonconductive support structure is incorporated into a conductive clamp for making electrical connection to the seed layer. An environmentally protective layer may be deposited upon the electrically conductive material to such an extent that the electronic circuit remains solderable. The three-dimensional mask may be fabricated by an additive manufacturing technique.
