Hitler decided the construction of the Sottevast site in July 1943 to target southeast England.
The bunker, built by the Organization Todt between 1943 and 1944, was intended to be a storage and servicing facility for launching V-2 ballistic missiles.
It was conceived to accommodate a missile regiment and a store for 300 missiles.

The bunker was located on an isolated piece of land to the north of the road to Valognes and to the east of the road to Brix, close to the latter municipality.
The site should have been serviced by a narrow gauge, considering that the main railway line was less than 200 metres (655 ft).

The L-shaped main building enclosed a large concrete pad, forming a 180 m long by 57 m wide rectangle with 4.50 m-thick walls.
Two other smaller bunkers were built on the site but no installations to produce liquid oxygen.

Sottevast was built using the technique known as "Verbunkerung".
Organisation Todt engineer Werner Flos devised a plan under which the 5-m thick roof would be built first, flat upon the ground, and the soil underneath it would be excavated so that the construction works below would be protected against aerial attacks.

While Watten and Wizernes were designed to be capable of frequently launching V-2 rockets and, by their size, future developments like the A9/A10, Sottevast was not designed to be capable of launching V2 rockets frequently.
The V2 rocket would have been transported by train to Sottevast, transferred to the narrow gauge train, serviced along the L-shaped building and launched from the same entrance.
This configuration would have made it difficult to launch more than a dozen of rockets per week, with a payload per rocket equivalent to that of a classical bomber.
According to Henshall, Sottevast and the other launch silos in the Cherbourg peninsula were not designed to launch V-2 rockets with conventional warheads but chemical warheads, with nerve gas like Tabun and Sarin, or radioactive warheads.

The site was partially completed when it was captured by the 504th Parachute Infantry Regiment of the 82nd Airborne Division during the Normandy campaign.
Generals Eisenhower and Bradley visited Sottevast days after D-Day.
The site was filled in by the US Army at the end of the war, under twenty metres of soil.
