Drachenbronn Air Base
Drachenbronn Air Base (''Base Aérienne 901 Drachenbronn'') of the French Air and Space Force is located in the community of Drachenbronn-Birlenbach in the Bas-Rhin département. It houses the '' Centre de détection et de contrôle 05/901.'' The base uses the underground facilities of the former Ouvrage Hochwald of the Maginot Line. Its mission is the surveillance of aviation movements in eastern France. Under budget cuts announced in October 2014 it will become an outstation of Nancy – Ochey Air Base. History In 1946 the Air Force began studies for the creation of a radar station on top of the ''ouvrage''. Construction began in 1952, and in 1955 major construction was undertaken in the ''ouvrage'' for a radar control room and operations center, which was placed in operation in 1957, originally designated ''Station Maître Radar 50/921''. The facility was briefly called ''Ouvrage H'' and was connected by data links to ''Ouvrage G'' at the Fort du Salbert near Belfort ...

Roundel Of France
A roundel is a circular disc used as a symbol. The term is used in heraldry, but also commonly used to refer to a type of national insignia used on military aircraft, generally circular in shape and usually comprising concentric rings of different colours. Other symbols also often use round shapes. Heraldry In heraldry, a ''roundel'' is a circular charge (heraldry), charge. ''Roundels'' are among the oldest charges used in coat of arms, coats of arms, dating from at least the twelfth century. Roundels in British heraldry have different names depending on their tincture (heraldry), tincture. Thus, while a roundel may be blazoned by its tincture, e.g., ''a roundel vert'' (literally "a roundel green"), it is more often described by a single word, in this case ''pomme'' (literally "apple", from the French) or, from the same origins, ''pomeis''—as in "Vert; on a cross Or five pomeis". One special example of a named roundel is the fountain (heraldry), fountain, depicted as ''a ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort Du Salbert
Fort du Salbert, also known as Fort Lefebvre, was built between 1874 and 1877. It was named after General François Joseph Lefebvre. It forms part of the Séré de Rivières system fortifications in the fortified region of Belfort in northeastern France. It is located at the summit of Salbert hill to the northwest of Belfort. During the early years of the Cold War it briefly served as an air defense coordination center. Séré de Rivières fort Fort du Salbert is one of the second ring of forts around Belfort, built about 5000 to 6000 meters outside the first ring of the 1840s. All of the new generation of forts abandoned sheer walls and bastions in favor of low earth-covered mounds to better resist artillery. After it became apparent that masonry forts would not resist explosive shells, the fort was modernized beginning in 1885 with concrete over the caponiers and the creation of underground shelters for troops. From 1893 the fort was connected to other Belfort forts by the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Air Defence Radar Systems
The French air defence organisation is integrated in the military Armée de l’Air (ALA), the French Air Force. The defence of the French national airspace has always been based on 2 main aspects: * the peacetime security of the French airspace. This assignment is executed according to the fixed conditions of the French prime minister collaborating with the ministers of transport, foreign affairs, industrial, postal and communication services, interior management and colonial management. * the national military air defence consisting of all defensive and counteroffensive measures against eventual aggressors. In peacetime, the air defence and air operations command develops and evaluates all possible classic assets of air operations in all kinds of theatres. In times of crises or at war, the air defence and air operations command is responsible for all offensive and defensive air operations. The ''Commandement de la défense aérienne et des opérations aériennes'' (CDAOA) is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maginot Line
The Maginot Line (french: Ligne Maginot, ), named after the French Minister of War André Maginot, is a line of concrete fortifications, obstacles and weapon installations built by France in the 1930s to deter invasion by Germany and force them to move around the fortifications. The Maginot Line was impervious to most forms of attack. In consequence, the Germans invaded through the Low Countries in 1940, passing it to the north. The line, which was supposed to be fully extended further towards the west to avoid such an occurrence, was finally scaled back in response to demands from Belgium. Indeed, Belgium feared it would be sacrificed in the event of another German invasion. The line has since become a metaphor for expensive efforts that offer a false sense of security. Constructed on the French side of its borders with Italy, Switzerland, Germany, Luxembourg and Belgium, the line did not extend to the English Channel. French strategy therefore envisioned a move into Belgium ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alsace
Alsace (, ; ; Low Alemannic German/ gsw-FR, Elsàss ; german: Elsass ; la, Alsatia) is a cultural region and a territorial collectivity in eastern France, on the west bank of the upper Rhine next to Germany and Switzerland. In 2020, it had a population of 1,898,533. Alsatian culture is characterized by a blend of Germanic and French influences. Until 1871, Alsace included the area now known as the Territoire de Belfort, which formed its southernmost part. From 1982 to 2016, Alsace was the smallest administrative ''région'' in metropolitan France, consisting of the Bas-Rhin and Haut-Rhin departments. Territorial reform passed by the French Parliament in 2014 resulted in the merger of the Alsace administrative region with Champagne-Ardenne and Lorraine to form Grand Est. On 1 January 2021, the departments of Bas-Rhin and Haut-Rhin merged into the new European Collectivity of Alsace but remained part of the region Grand Est.

Fort François De Guis
A fortification is a military construction or building designed for the defense of territories in warfare, and is also used to establish rule in a region during peacetime. The term is derived from Latin Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the ... ''fortis'' ("strong") and ''facere'' ("to make"). From very early history to modern times, defensive walls have often been necessary for cities to survive in an ever-changing world of invasion and conquest. Some settlements in the Indus Valley civilization were the first small cities to be fortified. In ancient Greece, large stone walls had been built in Mycenaean Greece, such as the ancient site of Mycenae (famous for the huge stone blocks of its 'cyclopean' walls).

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...
