A mast for use on a submarine is disclosed. The shape of the mast includes
a sharp leading edge. The leading edge widens to an angle greater than
the maximum angle of angle of attack that the mast will experience during
maneuvering. The shape produces a stagnation zone that minimizes flow
separations at the bow wave and has a pressure coefficient that
approaches zero such that wake signatures of the mast are reduced. The
surface of the mast is roughened to be capable of producing a turbulent
boundary layer of the mast further reducing wake signatures from the bow
wake.
