330-PSA-275-63-2:   Rocket motor and nuclear depth bomb speed on course after firing.  Because of its double transition from underwater to surface and back to water, the missile must incorporate the hydrodynamic characteristics of a torpedo and the aerodynamic characteristics of a missile, as well as a shock reducing device which permits the operation of the arming device and the warhead after water reentry at supersonic speed.
