Description
The JAS39A Gripen is a Swedish multirole fighter that entered service in 1996 to replace the aging JA37D and AJS37 for the Swedish air force. The JAS39A is developed by SAAB and was designed to carry out tasks such as defending Swedish airspace, engaging with hostile ground targets, and reconnaissance missions.
The JAS39A was introduced in Update "Air Superiority" as top rank jet fighter for Sweden, able to fight toe to toe with MiG-29s and F-16s on more even terms than the preceding JA37D. The JAS39A can be equipped with different types of anti-air missiles for air engagements, but also does come with different bomb loadouts making it able to be used in a ground supporting role, giving it a multirole ability to engage a variety of enemies. The JAS39A handles differently than its predecessor JA37D, but will be more similar to the F-16 that some may be used to.

Survivability and armour
Examine the survivability of the aircraft. Note how vulnerable the structure is and how secure the pilot is, whether the fuel tanks are armoured, etc. Describe the armour, if there is any, and also mention the vulnerability of other critical aircraft systems.

Usage in battles
Gripens needs to be played in one way which is very different from all the other top-tier jets. The JAS39A has an underwhelming radar-guided missile out of all its opponents, meaning it will not play ever in BVR engagements, since it will always end up losing. Instead, the Gripen shines in the furballs, where the chaos prevents anyone from being totally aware of its surroundings. There, it can use its two best assets: the RB 74(M) (a Swedish Version of the AIM-9M ) and the nearly-unlimited flares loadout the plane can carry. When approaching the danger zone, activate the automatic countermeasure release, set to cycle 1 sec with 0.5 sec between each release and 2 releases per cycle. You have about 4:30 minutes of pure adrenaline before you run out of flares (using flares and chaff should half the time, but sticking to the deck makes radar-guided missiles easily dodgeable). Now the player can pay less (not none) attention to their surroundings and focus on launching the RB 74(M) missiles. Do not focus too much on one target, lock on with radar so the missile won't go for the flares during the lock-on phase and prefer targets that are showing you their side: this way even if they flare the missile will be less likely to notice the flares at all. The Gripen is also a good dogfighter, use the air brake until you get into the 700-850 km/h, that way you will pull like a monster.
Pros and cons
Pros:
- High speed; good acceleration gets you back in the fight after losing speed in turns or climbs
- Extreme maneuverability - currently possibly the most agile fighter in the game, outturns even F-16s!
- High amount of countermeasures available; a total of 720 when carrying four BOL rails on the wings
- Well balanced loadouts available, ranging from dumb bombs and rockets to F&F AGMs and laser guided bombs
- Helmet mounted sight lets the pilot slew both IR missile seekers as well as the radar onto off-bore targets
- Access to very competitive RB74(M) missiles which are highly resistant to flares
Cons:
- Prone to tear off wings at high speed; its high agility may result in over-G breaking the plane apart with reckless maneuvering
- Mediocre radar missiles; very short range compared to the AIM-7Ms and R-27ERs carried by contemporaries
- Low ammo count for a relatively rapid firing cannon
- Canard-delta design combined with its tiny size means that any hit is likely to cause critical damage to your flight surfaces
History
Describe the history of the creation and combat usage of the aircraft 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: https://wiki.warthunder.com/(Vehicle-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />. This section may also include the vehicle's dev blog entry (if applicable) and the in-game encyclopedia description (under === In-game description ===, also if applicable).
