Mount Yarokovo

Mount Yarokovo - known formally as National Defence Complex Mount Yarokovo (Arvorian: Комплекс национальной обороны Гора Яроково, Hallisised: Kompleks natsional'noy oborony Gora Yarokovo) and also as An-02 - is an Arvorian military facility operated by the Arvorian Air Force located 19.3 kilometres (12 miles) northwest of the town of Dmiznetsk in Tura Oblast, 191.5 kilometres (119 miles) north of the oblast seat at Lenigansk.

Mount Yarokovo is a Site of National Security Significance (Arvorian: Объект, имеющий значение национальной безопасности, Hallisised: Ob"yekt imeyushchiy znacheniye natsional'noy bezopasnosti) and Basic Continuity of Government (Arvorian: Основная преемственность правительства, Hallisised: Osnovnaya preyemstvennost' pravitel'stva) facility. Air Base Dmiznetsk is located five kilometers (3.1 miles) west of the mountain and is home to 91 through 94 Squadrons of the Arvorian Air Force. The entire area is part of the Ninth Military District, with the district commander based out of Mount Yarokovo itself.

Overview

Mount Yarokovo monitors the aerospace of Arvor and all of D'Runia, tracking missiles, space systems, and foreign aircraft through its early-warning and remote monitoring systems. It has been the home of Strategic Air Command (Arvorian: Стратегическое авиационное командование, Hallisised: Strategicheskoye aviatsionnoye komandovaniye) since its construction and is also the home of the national civil defence communications centre, being the site of a section of the Main Communications Directorate of the Ministry of Defence, with one of the central nodes of the All-Republic Comprehensive System for Information and Warning (Arvorian: Общереспубликанская комплексная система информации и оповещения, ОКСИО, Hallisised: Obshcherespublikanskaya kompleksnaya sistema informatsii i opoveshcheniya, OKSIO).

The main control stations for two important systems - the D'Runia Integrated Radar Defence System (Arvorian: Интегрированная система радиолокационной защиты Д'Руния, Hallisised: Integrirovannaya sistema radiolokatsionnoy zashchity D'Runiya, ИсрзД or ISRZD) and the Tracking and Data Relay Satellite System (Arvorian: Спутниковая система слежения и ретрансляции данных, Hallisised: Sputnikovaya sistema slezheniya i retranslyatsii dannykh, Сссрд) - are located here. The complex is also home to AURORA, the IR12 Strela-V supercomputer that serves to co-ordinate and process data flows on international military and political affairs in support of AFA analysts and planners.

Facilities

Main chambers

While one-fifth of the complex sits above ground, the remainder is built deep into Mount Yarokovo itself, underneath 762 metres (2,500 feet) of solid granite and encompassing 33 buildings on five hectares (12.3 acres). The buildings are protected from movement by a system of giant springs and flexible pipe connectors to limit the operational effect of movement. The springs, more than 2,000 of them, are designed to prevent any of the buildings from shifting more than 25 millimetres (one inch). The complex is certified to be able to sustain an electromagnetic pulse (EMP). Three of the buildings are dedicated to housing facilities for base staff, including suites for high-ranking officers within the bunker. Amenities include an infirmary, commissary, cafeteria, recreation centre, and a fitness centre.

In a time of severe national emergency, the president and premier would relocate here. Two special suites of rooms are set aside solely for their use.

Blast doors

The bunker is built to deflect a 30-megaton nuclear explosion as close as 2 kilometres (1.2 mi). Within the main access tunnel are sets of 22.7 metric tonne blast doors and another set for the engineering department. The doors were built so that they can always be opened when needed. Should a nuclear blast hit the building, they are designed to withstand a blast wave. There is a network of blast valves with unique filters to capture airborne chemical, biological, radiological, and nuclear contaminants.

Outdoor

Outside of the military complex are the car park and a fire station, as well as the offices for certain non-critical services maintained at the facility. Both roads leading up to the mountain's primary access tunnel is guarded all hours of the day by armed military police. All who would gain access to the facility must have the appropriate clearance and authorisation.

Support area

The complex has its own nuclear generating station, two biodiesel-fired backup generators, a heating and cooling system, and water supply. It is the job of the engineers on site to ensure that there is a 99.999% degree of reliability of its electricity, water, air conditioning and other support systems. The threats that the complex may face, in descending order of likelihood, are "medical emergencies, natural disasters, civil disorder, a conventional attack, an electromagnetic pulse attack, chemical or biological or radiological attack, an improvised nuclear attack, a limited nuclear attack, and a general nuclear attack." The least likely events are the most hazardous.

As more water is produced by the underground mountain spring than the base needs, there is a 7,750 cubic metre (7.57 million litre) reservoir to ensure that even in event of fire, there is enough water to meet the facility's needs. A secondary reservoir of 17.03 million litres (17,000 m3) of water is used as a heat sink. There is also an extensive battery bank installed as a redundant power supply.
