Sentralanlegget

Sentralanlegget is a physics topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sentralanlegget rather than just read about it. In short: Sentralanlegget (lit. The Central Facility) is the war headquarters of the Norwegian government, built during the Cold War.

Key takeaways

Sentralanlegget belongs to physics; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Sentralanlegget to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Sentralanlegget from memory before moving on to harder problems.

Reference excerpt

Sentralanlegget (lit. The Central Facility) is the war headquarters of the Norwegian government, built during the Cold War. The facility is located in Hole municipality in Buskerud County, and designed as an underground shelter in the west side of the mountain Kongens utsikt, meant to withstand a hit from a nuclear missile from the east.

History Sentralanlegget was built by the civil defense authority during the 1960s. The Cold War and the threats represented by the Soviet Union made it necessary to build a facility where members of the Norwegian royal family, members of the government and other key personnel could evacuate to in case of a military attack on the nation. Hole municipality was chosen due to its massive mountain range, ideal for an underground shelter, and because of its relative proximity to the governmental offices and the Royal Palace in Oslo. The end of the Cold War marked a change in the threats against Norway, as the neighboring Soviet Union no longer existed. Seen in the light of the modern world, this facility is now outdated in many ways. Nevertheless, it is still in operation and can be used if necessary. During the 1980s, the Norwegian government built a new, smaller and more modern war headquarter in a bunker under the governmental offices in Oslo. This, though, can not accommodate a larger number of persons for a longer time.

Function Sentralanlegget has two main entrances located some three hundred meters apart. From these, tunnels lead to the facility inside the mountain. The facility can accommodate 600 persons for months, and includes a hospital, restaurant/bar, communication central, conference rooms, situation room, private rooms for members of the government and the royal family and storage rooms for supplies. The facility is self-contained with power, water, air and food. It is the Directorate for Civil Protection and Emergency Planning that is responsible for the daily operation of Sentralanlegget. The Ministry of Justice and the Police and the Prime Ministers Office are also involved.

Secrecy Due to the sensitive nature of such a facility, location and technical details are classified. The entrances are digitally removed from aerial photos in Norwegian internet search engines. During the 1980s, journalists in a newspaper for a leftist pacifist organisation were threatened with legal action by the Prime Ministers Office if they published a story on the facility. In April 2010, the Norwegian Broadcasting Corporation reported that phone numbers, address, and the number of employees could be found in Norwegian search engines and telephone books. All information was provided by the Directorate for Civil Protection and Emergency Planning, most likely caused by a human error. Journalists also found technical drawings and lists of security cleared personnel lying open for everyone in the Norwegian state archive. These were later withdrawn. In 2018, Aftenposten reported that the bus stop in front of the secret entrance was called "NATO-facility".

Worked examples

Example 1 — a first encounter with Sentralanlegget

Start with the simplest possible case. Write down what Sentralanlegget claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In physics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sentralanlegget before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sentralanlegget ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sentralanlegget

In research: Sentralanlegget appears in physics research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sentralanlegget in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sentralanlegget is common in secondary-school and first-year university syllabi. It links to neighbouring topics Buildings and structures in Buskerud, Continuity of government, Emergency management in Norway, so understanding it makes those chapters shorter.
In everyday life: Look for Sentralanlegget outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
