The Gossberg (German: Goßberg) is a hill with the highest point of 483 m in the municipality of Wüschheim close to the border with Hundheim in the district of Rhein-Hunsrück-Kreis in the low mountain range of Hunsrück in the state of Rhineland-Palatinate, Germany.

Forces), during 1984–1989 was excavated 30 m deep in order to accommodate the subsequently constructed NBC (Nuclear, Biological, Chemical) bunker to be operated by the MT unit, which was already stationed about 4 km southwest of Gossberg in the direction of Kappel on the federal highway B 327.

Responsibilities of the MT unit at Gossberg included the signals intelligence (SIGINT), the communications security (COMSEC), the radar, the determination of targets, the air defense, and most prominently the control of ready-to-fire launch facilities for cruise missiles carrying nuclear warheads (and their corresponding guidance) located at the nearby (approximately 3 km north of the bunker) missile base Pydna (known under the code name of the Wüschheim Air Station) between Bell and Hasselbach.

Both shield hulls are separated by hollow space with a width of 2.00 m, which serves three major purposes: The thickness of the bottom plate is 1.00 m, while of the cover plate of the inner shield hull is between 1.00 m and 1.20 m. The cover plate of the outer shield hull consists of a so-called Zerschellschicht (a layer of lean concrete on top of the reinforced concrete construction to mitigate damage inflicted by explosions) with a thickness of 1.05 m and an overlying layer of fluid concrete with quartzite blocks with a thickness of 1.10 m. Finally, there is a soil layer of 0.40 m on top as a green roof.

By default, it contains nine rooms, but could be expeditiously reconfigured (by operating staff on their own, potentially during ongoing war) thanks to (re)movable walls, suspended ceiling, and raised floor (on stilts).

Other features include: The purpose of story 1 (underground floor) is to technologically sustain the building and provide storage space (e.g. for food, equipment, weapons, etc.

Other features include: The purpose of story 0 (underground floor) is to technologically sustain the building and provide storage tanks (e.g. for water and oil).

It contains road and parking paved with interlocking brick stones, which officially offers a helipad, a small transformer building, and a hill of about 10.35 m high with an entrance to the bunker.
