Strange Tales #150

Fury subjects himself to a dangerous test in order to prove that an atomic missile can be detonated long-distance by a sonic weapon which SHIELD believes HYDRA has. While both he & Dugan are recovering from injuries, Don Cabellero, at the urging of an undercover SHIELD man, invites Fury to a party in ancient Karnopolis in the Sahara Desert. Caballero is a disguise for the new Supreme Hydra, who is aware a SHIELD agent has invaded his ranks. Fury tells Sitwell he will be in command during his absence but suddenly a sonic boom shakes the HQ as the Overkill Horn is being tested.
