Military
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. It is typically authorized and maintained by a sovereign state, with its members identifiable by their distinct military uniform. It may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of the military is usually defined as defence of the state and its interests against external armed threats. In broad usage, the terms ''armed forces'' and ''military'' are often treated as synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include both its military and other paramilitary forces. There are various forms of irregular military forces, not belonging to a recognized state; though they share many attributes with regular military forces, they are less often referred to as simply ''military''. A nation's milit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientific
Science is a systematic endeavor that builds and organizes knowledge in the form of testable explanations and predictions about the universe. Science may be as old as the human species, and some of the earliest archeological evidence for scientific reasoning is tens of thousands of years old. The earliest written records in the history of science come from Ancient Egypt and Mesopotamia in around 3000 to 1200 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to provide explanations of events in the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages, but was preserved in the Muslim world during the Islamic Golden Age and later by the efforts of Byzantine Greek scholars who br ...

Cheyenne Mountain Complex
The Cheyenne Mountain Complex is a Space Force installation and defensive bunker located in unincorporated El Paso County, Colorado, next to the city of Colorado Springs, at the Cheyenne Mountain Space Force Station, which hosts the activities of several tenant units. Also located in Colorado Springs is Peterson Space Force Base, where the North American Aerospace Defense Command (NORAD) and United States Northern Command (USNORTHCOM) headquarters are located. Formerly the center for the United States Space Command and NORAD, the Complex monitored the air space of Canada and the United States for missiles, space systems, and foreign aircraft through its worldwide early-warning system. Since 2008, NORAD and the United States Space Command have been based at Peterson Space Force Base and the complex, re-designated as an Air Force station, is used for crew training and as a back-up command center if required. The military complex has included, in the past, many units of N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chiashan Air Force Base
Chiashan Air Force Base () is a military airport operated by the Republic of China Air Force in Hualien County, Taiwan. It is known for its extensive underground hangars. Hualien Airport operates within a 28-acre civilian section of the base. It is one of the most important defense installations on Taiwan as it houses the military's most survivable aerial counter-attack forces. History In 2018 the Air Force issued a solicitation for an automated CIWS system to add an additional layer of protection to Chihhang Air Base and Chiashan Air Force Base. Facilities Construction of the main underground section of the base spanned from 1985 to 1993 and cost more than 27 billion NTD to build. The underground hangars can accommodate approximately 200 fighters. The underground complex has ten blast doors which exit to multiple runways. It also has its own hospital as well as multiple underground gas stations. See also *Taoyuan Air Base *Ching Chuan Kang Air Base Ching Chuan Kan ...

Iranian Underground Missile Bases
According to Iranian authorities, Iranian underground missile bases or silos ( fa, پایگاه های موشکی زیرزمینی ایران ), also known as the Missile Cities ( fa, شهرهای موشکی) exist in all provinces and cities of Iran. The bases contain road-mobile transporter erector launcher trucks, along with other hardware. A video from one of the missile sites was released for the first time on 14 October 2015 by Brigadier General Amir Ali Hajizadeh, commander of Aerospace Force of the Army of the Guardians of the Islamic Revolution. This was just a few days after news of the testing of a new-generation medium-range ballistic missile, the Emad, was broadcast by the state media of Iran. Amir Ali Hajizadeh stated that: "Iranian missiles of varying ranges are ready to be launched from underground bases once Supreme Leader Ayatollah Ali Khamenei orders to do so," adding that "Iran created missile bases in all the provinces and cities throughout the country at a ...

Underground Living
Underground living refers to living below the ground's surface, whether in natural or manmade caves or structures. Underground dwellings are an alternative to above-ground dwellings for some home seekers, including those who are looking to minimize impact on the environment. Factories and office buildings can benefit from underground facilities for many of the same reasons as underground dwellings such as noise abatement, energy use, and security. Some advantages of underground houses include resistance to severe weather, quiet living space, an unobtrusive presence in the surrounding landscape, and a nearly constant interior temperature due to the natural insulating properties of the surrounding earth. One appeal is the energy efficiency and environmental friendliness of underground dwellings. However, underground living does have certain disadvantages, such as the potential for flooding, which in some cases may require special pumping systems to be installed. It is the prefe ...
