There can be attitude transients caused by hydrodynamic effects of the
passage through the water as well as the effects of breaking the
surface. ('Tail slap' as the missile exits is of particular concern.)
Polaris was acutely sensitive to this because of their need to perform
a roll maneuver immediately upon ignition.
Coincidentally, History Channel this morning ran a show about the ICBM
Race and included Polaris launch footage. That roll was damned
impressive!
