You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 34.200.0.0/16 has been blocked by ‪JJMC89‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 05:16, 2 September 2025. Your current IP address is 34.200.225.90.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

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 crisis 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 the air defence and air operations command, and has the following primary missions:
* to decelerate and to evaluate any possible threats to the country by controlling the French and surrounding airspace by radar
* to present an actual airpicture on a  24/7 basis to all civilian and military authorities on which strategic decisions may be made
* to secure the airsuperiority in the national airspace at all times
* to prevent or to stop the use of the national airspace by any kind of aggressor
* to alert all civilian and military authorities in case of surprise air attacks

CDAOA secondary, peacetime, missions are:
* to command and control all military air traffic  in cooperation with the civilian air traffic under the authority of the minister of transport
* to command and control all search and rescue operations in case of civilian or military air accidents

In case of need the main CDAOA functions will always be guaranteed on all theatres by the activation of air, ground or sea mobile detection units of all French armed forces. These units may be deployed at any time to support the fixed operational systems.

==System elements==
*'''STRIDA''' (''Système de Traitement et de Représentation des Informations de Défense Aérienne'', lit. "System for processing and representing air defence information") is the radar itself. They equip the CDAOA, the CCOA, the CDC's and the UDA
*'''[[PALMIER]].''' are 3-dimensional and 2-dimensional radars in the 23&nbsp;cm wavelength. They feed information to the CDCs, which exchange their radar inputs from the other CDC's, from foreign allied [[NATO]] CRC's and from the E-3F and E-2C planes to complete the situation awareness.
*'''VISU- IV/ -V''' are computerised workspaces staffed and operated by military controllers that can be operated in control mode or surveillance mode. A senior controller is always in charge of supervising the operators. The VISU- IV/ -V equip the CDCs and UDA.
*'''METEOR and ETEC''' are radio and datalink communication systems. They constitute the primary means of transmission, though telephone and radio transmissions may also be sent via other specific sources in the defence network, such as Socrate or MTBA, or even through the installations of [[France Télécom]].

==Air defence chain of command==
The operational air defence [[command hierarchy|chain of command]] consist of 3 main parts.

*The '''Centre de Conduite des Opérations Aériennes''' (CCOA), the air operations command and control centre where the overall air picture is generated and evaluated, is responsible for all air operations and for the security of the French airspace. This military authority is directly under the French President.

The CCOA, is located in an underground facility on [[Taverny Air Base]] (''Base aérienne 921 ‘Frères Mahe’'') near the town of [[Taverny]]. In radiotraffic it uses the tactical call sign (tactical) “Veilleur’

*The '''Centres de Détection et de Contrôle (CDC),''' the control & reporting centres are  placed in the commandstructure of the Commandement Air des Systèmes de Surveillance, d’Information et de Communications (CASSIC) and are the subordinating units to the CDAOA.

There are 5 fully operational CDC's in the new ALA structure. These command & reporting centres are
* ''CDC 05.901 Drachenbronn'' located on [[Drachenbronn Air Base]] (''Base aérienne 901 ‘Capitaine de Laubier''') at the town of [[Birlenbach]] with the tactical “Riesling radar”.
* ''CDC 05.942 Lyon/Mont Verdun'' located on [[Lyon - Mont Verdun Air Base]] (''Base aérienne 942 ‘Capitaine Robert’'') at the city of [[Lyon]] with the tactical “Rambert radar”.
* ''CDC 05.943 Nice/Mont Agel'' located on [[Nice Air Base]] (''Base aérienne 943 ‘Capitaine Auber’'') at the town of [[Roquebrune-Cap Martin]] with the tactical “Rhodia radar”.
* ''CDC 04.930 Mont-de-Marsan'' located on [[Mont-de-Marsan Air Base]] (''Base aérienne 118 ‘Colonel  Rozanoff’'') north of [[Mont-de-Marsan]] city with the tactical “Marina radar”.
* ''CDC 07.927 Cinq-Mars la Pile'' is an air detachment of [[Tours - Saint-Symphorien Air Base]] (''Base aérienne 705 ‘Commandants Tulasne’'') at [[Tours]] with the tactical “Raki radar”.

The former CDC 05.902 located on airbase 902 at [[Contrexéville]] and the former CDC located on air detachment 922 at [[Doullens]] have been deactivated and transformed into radiocommunications and satellite control stations. Although their infrastructure is still present and conserved the radar stations are not operational anymore.

*The '''Unité de détection aéroportée (UDA)''', the French airborne early warning (AWACS) unit located on airbase 702 ‘Cne Georges Madon’ near the town of [[Avord]] with the unit tactical  "Cyrano". This airborne early warning unit, has been created in 1989 on the Avord airbase and consists of

''36th Escadre de détection aéroportée'' (36 EDA), becoming operational in 1990 and equipped with 4 E-3F AWACS planes during 1990–1992.

''Escadron de détection aéroportée'' (EDA 01.036) ''Berry'' and ''EDA 02.036 Nivernais'' are the 2 operational E-3F squadrons

''Escadron de préparation des missions et simulation'' (ESMT 10.036) and ''Escadron de soutien technique spécialisé'' (ESTS 15.036), the mission supporting and the technical maintenance squadrons.
