== Description ==
<!-- ''In the description, the first part should be about the history of the creation and combat usage of the vehicle, as well as its key features. In the second part, tell the reader about the ground vehicle in the game. Insert a screenshot of the vehicle, so that if the novice player does not remember the vehicle by name, he will immediately understand what kind of vehicle the article is talking about.'' -->
The '''{{Specs|name}}''' is a rank {{Specs|rank}} British tank destroyer {{Battle-rating}}. It was introduced in [[Update "Hot Tracks"]].

== Usage in battles ==
<!-- ''Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).'' -->

=== Pros and cons ===
<!-- ''Summarise and briefly evaluate the vehicle in terms of its characteristics and combat effectiveness. Mark its pros and cons in a bulleted list. Try not to use more than 6 points for each of the characteristics. Avoid using categorical definitions such as "bad", "good" and the like - use substitutions with softer forms such as "inadequate" and "effective".'' -->

'''Pros:'''

* Has 8 multi purpose missiles that can destroy both tanks and aircraft
* Missiles can penetrate 900 mm of armour
* Missiles have a range of 10 km
* One of the fastest missiles in the game (1,200 m/s)
* Missiles aren't affected by infrared APS such as on [[T-90A]] or [[AMX-30B2 BRENUS]]
* Lower profile than the American [[ADATS]] - especially with the radar folded down
* Far easier to use and more effective in the AA role than its predecessor, the [[Stormer HVM]]
* Missile launchers can elevate higher than the ones on the American ADATS
* Missiles are armed with a proximity fuse, meaning a direct hit isn't needed to down an aircraft

'''Cons:'''

* Really fragile, can be penetrated by autocannons and high-calibre machine guns
* Long antennas might give your position
* Unable to depress the launcher below horizontal - unable to engage tanks lower than you or low flying aerial vehicles
* Lacks the 25 mm gun found on the American ADATS
* Smoke launchers are mounted on the front of the vehicle - hull must face the direction of smokescreen deployment
* The M113 chassis has a low hp/ton ratio - mobility is severely reduced off-road, in mud, snow, and sand
* No ESS
* Low reactive mobility
* Only 8 missiles - after these are used they must be reloaded on a capture point which takes quite some time
* Missiles need to travel a certain distance to arm the fuze - unable to engage enemy aerial vehicles at close range, except for a direct hit

== History ==
<!-- ''Describe the history of the creation and combat usage of the vehicle in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the vehicle and adding a block "/History" (example: <nowiki>https://wiki.warthunder.com/(Vehicle-name)/History</nowiki>) and add a link to it here using the <code>main</code> template. Be sure to reference text and sources by using <code><nowiki><ref></ref></nowiki></code>, as well as adding them at the end of the article with <code><nowiki><references /></nowiki></code>. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under <code><nowiki>=== In-game description ===</nowiki></code>, also if applicable).'' -->The ADATS (M113) was a Canadian-operated anti-aircraft and anti-tank missile carrier system, designed to engage both ground and air targets. Developed in the early 1970s by Oerlikon-Buhrle (now part of Rheinmetall), the AA system failed to see service with the countries it was intended for, namely the United States. However, the Canadian armed forces procured 36 ADATs vehicles based on the M113 chassis, which served with the Canadian army as anti-aircraft systems until their withdrawal in 2007.

=== Design and Development ===
In the early 1970s, Oerlikon-Buhrle began the process of developing a new vehicle, designed for both anti-tank and anti-aircraft defence. This vehicle would later become the ADATs. In 1979, Martin-Marietta joined the design process. The vehicle was designed to compete in the FAAD (Forward Area Air Defence) competition for the US Department of Defence, which wished to replace it’s interim [[M163]]/M167 Vulcan Anti-Aircraft guns and the MIM-72 Corporal anti-aircraft systems. The ADATS ended up winning the competition, beating out competitors including the Franco-German-designed Roland.

However, the ADATs encountered a number of critical issues with it’s operability. Namely, it had an extremely high mechanical failure rate resulting in a very low operational readiness. And, in 1990, the Cold War ended; that was the final straw for the ADATS. As a result, the US DoD cancelled the ADATS program, after almost five billion dollars of funding. Despite this, the Canadian government ordered the ADATS for their Low Level Air Defence (LLAD) program, spending 1.09 billion dollars to purchase 36 ADATS vehicles along with the necessary equipment.

The ADATS was highly unique in that it was designed for both anti-air and anti-ground defence. Based on the M113 APC chassis, the weapon system was composed of eight ADATS missiles, along with a search radar and laser missile director. The Canadian version was not fitted with the M242 Bushmaster cannon fitted to American ADATS SPAAs. The missiles themselves were laser-guided, and had a combined HEAT/HE-Frag warhead capable of penetrating 900 mm of armour. This system enabled the ADATS to destroy both tanks and helicopters from a maximum range of 10 km, or 7 km altitude.

=== Operational History ===
The ADATS entered service with the Canadian armed forces in 1989, and was built by Oerlikon Aerospace, based in Quebec. The ADATS saw combat just once, being deployed by the Canadian armed forces during the Gulf War. However, it never actually saw combat, and never fired a shot in anger. The ADATS was unusually expensive for an anti-aircraft vehicle, due to its large design and development costs and small order in terms of vehicles. As a result, the Canadian Armed Forces announced that they would retire the ADATS in 2006. By 2007, all ADATS vehicles had been withdrawn from Canadian service.
