The Base, active from 1966 to 1977, housed three launch sections: the Alpha section (which coincides with the current Base Tuono) located to the south, at the foot of the Maggio mountain; the Bravo section, located in the western sector and the Charlie section, located in the north-west sector. It had twelve Nike-Hercules missiles armed with conventional warhead. The Charlie section was never equipped with missiles, so the only armed sections were Alpha and Bravo.
As the Control Area of Mount Toraro (located 3240 m of distance in direct eye contact), the Launch area of Passo Coe was assigned to 66th Group IT whose command and logistics headquarters was situated in Tonezza, 18 km away.
Near the Launch Area, about 200 meters away, there was the Logistics Decentralized Area (accommodation buildings). The entire Base was bounded by a perimeter fence. Inside the Base, the sections Alpha and Bravo - having been approved for the launch of Hercules missiles armed with nuclear warheads (which were never present in the area) - were enclosed within a second fence.
