An extendible probe projectile and an extendible probe assembly therefor, in which the extendible probe reduces drag on the projectile in its extended position and is moved to its extended locked drag-reducing position by ram air action which is converted into a forwardly acting force on the probe during forward motion of the projectile.

A projectile having an extendable fluid contacting slip-stream forking probe in its forward end, said probe being slidably movable forwardly within said projectile as a function of and in response to fluid pressure rearwardly acting on said forward end of said projectile, said projectile having probe guide means at the forward end thereof and within which said probe is slidable, said probe being peripherally smaller along its forward end zone than said guide means and being thereby substantially freely slidable along its initial forward travel within said forward end probe guide means, and said probe being peripherally larger than said forward end guide means and forming a force fit therewithin whereby said probe is frictionally restrictedly by said forward end zone probe guide means during a subsequent terminal portion of its forward travel within said guide means.
