 The original Hermes A-2 was projected to be a wingless A-1, but that missile was abandoned to be followed by another rocket called A-2 (RV-A-10).The RV-A10 was a short range solid fuel test vehicle, with plans to develop a tactical missile (SSM-A-13,) which were soon abandoned.The slightly larger Hermes A-3A (SSM-G-8, RV-A-8) followed.
