Speer gave orders that two bunkers were to be constructed by the Organisation Todt construction group to a "special fortification standard" ("Sonderbaustärke"), requiring a steel-reinforced concrete ceiling thick and walls thick. They would be built near the coasts opposite England, one on the Côte d'Opale near Boulogne-sur-Mer and the other on the Cotentin Peninsula near Cherbourg. Each would be capable of launching 36 missiles a day, would hold sufficient supplies of missiles and fuel to last three days, and would be manned by 250 troops.
