with a battle rating of 10.0 (AB), 10.3 (RB), and 10.7 (SB). It was introduced in Update 1.97 "Viking Fury".
The J35D is the first Swedish jet capable at Mach 2. The jet is highly agile and is the first plane in War Thunder capable of performing the famous "Cobra maneuver".
General info
Flight performance
The J35D Draken is a highly agile interceptor of the Swedish aviation family. This interceptor uses a double delta wing-configuration and a powerful Avon engine to achieve both excellent high and low-speed performance at various altitudes. This aircraft is outfitted with two wing-mounted Akan m/55 auto-cannons and up to four Rb24 missiles. Along with options for both anti-air and anti-ground rockets, the J35D becomes a versatile platform with a high potential thanks to unmatched maneuverability. Having almost twice the wing surface of a MiG-21MF, the J35D comfortably dogfights any opponent who dares to challenge it.
The cost of this maneuverability is the large reduction in speed when turning. The J35D usually drops below 500 km/h airspeed when performing aggressive maneuvers. This lack of speed usually leaves the J35D vulnerable to enemy attacks, since avoiding missiles or gunfire becomes a lot more difficult. This makes the J35D a unique flying experience where the player needs to be constantly aware of the current airspeed, while still avoiding to dump all speed at once. In order to maximize the stored speed, a J35D should be flown carefully. Aerial maneuvers should be avoided and turning has to be done slowly. The efficiency of the J35D significantly increases when played with higher speeds. Although the plane becomes more sluggish at speeds close to 1,100 km/h, the J35D still manages to outmaneuver incoming missiles. Avoiding incoming homing devices usually leads to deceleration, but with careful planning, this speed can always be regained thanks to the strong acceleration the engine provides.

Survivability and armour
The J35D is one of the few high-rank planes entirely without protection, much like the F-4 Phantom series of fighters. Although the later variants of the Draken featured bird strike-proof cockpits, no Draken variant was fitted with armour plating or bulletproof glass. In-game, this downside can be quite hard to notice since higher rank vehicles tend to boast incredible amounts of firepower, making every hit incredibly devastating. A J35D pilot should, like every other pilot, avoid damages at all costs as any damage deteriorates the aircraft's performance and ability to stay in the fight.
Armaments
Offensive armament
The J35D is outfitted with two 30mm Akan m/55 cannons, which are Swedish manufactured variants of the British ADEN cannons. These two cannons offer a high burst mass and velocity at medium ranges. Although these guns are dangerous, they are quite limited by their ammunition count. Just like the J32B, these cannons have 90 rounds each, giving the player a total of 180 shells. The cannons should be fired with caution in order to maximize the amount of damage they provide. Since the missiles are outdated Rb24 missiles, a J35D pilot needs to be prepared to engage most enemies with these cannons rather than suspended armaments.
Another issue with the J35D is the cannon placement. The two Akans are wing-mounted rather than centre-mounted. This is a downgrade compared to the centre-mounted position found on the J32B since set convergence now plays a role. This makes the J35D lose effectiveness at certain ranges since the target has the chance to fly between the shells, and when hitting a target, the shells are unlikely to concentrate to a singular point, lowering the amount of damage created. This placement creates difficulty in complex manoeuvres, since putting the plane sideways creates a vertical spread. A wise J35D pilot will commence target practice with the guns prior to battle as they are important for the plane’s overall survivability and combat effectiveness.
Suspended armament
Describe the aircraft's suspended armament: additional cannons under the wings, bombs, rockets and torpedoes. This section is especially important for bombers and attackers. If there is no suspended weaponry remove this subsection.
Usage in battles
Describe the tactics of playing in the aircraft, the features of using aircraft in a 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. Examine 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
Pros:
- Superior manoeuvrability - Able to out-turn anything it wishes
- High top speed - Can catch most top tier aircraft at low altitudes
- Strong acceleration
- Decent firepower
- Easy and short takeoff/landing
- Slow stall speed - Air-brakes prevent "superstalling"
Cons:
- Poor sustained turning - sustained speed degenerates quickly when manoeuvring at speeds below 1,000 kph
- Outdated missiles - unable to reliably eliminate observant opponents
- Unorthodox gun placement - less accurate and more tricky to get used to
- Lack of countermeasures - No flares or RWR

Fun Fact: Pilots of the J35D created a term called superstalling, unlike typical aircraft which would stall, nose over, and recover, the Draken's control surfaces remain ineffective for some time as the aircraft falls, potentially causing it to crash. |
History
- Background
The discussion about a new fighter project, capable of intercepting small groups of bombers at an altitude of 10 kilometres, was brought up in the autumn of 1949, just a few months from the introduction of the J29 Tunnan. The threat was deemed to be transonic bombers, which needed to be intercepted before reaching Swedish airspace. This meant the next big project, Saab would focus on a high-speed interceptor capable of exceeding the Mach number, while still being able to function as an all-weather, daytime fighter.
- Saab 210 Lilldraken
This new project for a supersonic fighter-interceptor was given the name "project 1200". This project would be lead by the Saab engineer Erik Bratt. His team tinkered with various ideas on how to create a supersonic fighter with low-speed handling, to ease landing on shorter runways. The team came up with a double delta design that made use of two wing angles, giving the plane less drag at higher speeds, while staying manoeuvrable at lower speeds. In order to test this design, the team constructed a miniature version of the new fighter, named Saab 210, which also received the nickname "Lilldraken" (translates to small kite). This plane was just 70% the size of the regular Draken and was used for extensive testing of handling as well as ergonomics of a double delta configuration. This prototype was first flown on January 21st, 1952.
The Saab 210 would see many changes to its design in order to finalize the look of the upcoming J35 Draken. The nose was changed to better suit radar use, its air intakes moved back for a better view, and the tail reconstructed to fit a drag-chute. All of which would be found on the J35 Draken later on.
- Saab 35 Draken
With the tests finished, the Draken would finally see full-scale prototypes. The first prototype took to the skies in October 1955, and deliveries of the first variant, the J35A, would commence in 1959. By 1960 the first Drakens would officially be in service. These would be stationed at F13 Bråvalla and F16 Gotland. Later variants would be placed all over Sweden, with various purposes. Being used for bomber interception, reconnaissance and trainers, the Saab 35 Draken would see the longest service life of any fighter in the Swedish air force. The Draken would serve for almost 40 years, having 615 planes produced during its lifespan.
- J35D Draken
The J35D was the 4th Draken variant that was planned and built due to the new requirements the Swedish KFF (Kungliga FlygFörvaltningen or Royal air ministry) issued to Saab. The new requirements specified that the next fighter had to intercept high altitude bombers flying at Mach 1.5, while still carrying the same weaponry and ordinance the earlier J35B offered. This required Saab to upgrade the RM6B engine found on the J35B, which meant the design had to be slightly altered. The air intakes were elongated, and the fuselage got altered to support the use of drop-tanks in the centre. The first J35D took to the skies on the 28th of August 1962, but the first planes delivered would be without radar equipment. These would be known as the J35D1, of which 24 of which were made. The other planes got the name J35D2 and would later be known as the J35D when the original D1s got their radar equipment installed.
A total of 120 J35D Drakens would be built between 1963-1964. Being outfitted with the Rm 6C (Avon 300-series), this version was the fastest Draken to take to the skies. This Draken would also be exported to the Austrian air-force. In order to export these planes to Austria, Saab ended up buying back 24 of the Swedish serving J35Ds and converting them to the Austrian requirements, which meant fitting the planes with the bird-proof cockpit from the J35F, as well as repainting them for Austrian service. These Austrian Drakens, designated J35Ö (sometimes designated J35OE), saw extensive use all the way towards the 21st century, being taken out of service in 2005.

In the late 1940s, the Swedish Ministry of Defence released a set of requirements for a new, cutting edge jet interceptor. Among other requirements, the new aircraft was to be capable of reaching speeds of Mach 2 and able to hunt down transonic bombers, while being easily maintained and capable of taking off from special public roads.
Saab began developing an aircraft around these specifications in the early 1950s and quickly came to the conclusion that a double delta wing design was needed in order to achieve all the requirements. However, this design was yet untried and untested, which led to the creation of the Saab 210 - a testbed aircraft which pioneered the double delta wing design.
Having gained the necessary insight on the performance of the double delta wing, Saab engineers transferred the newly acquired experience into the development of the actual aircraft to address the Ministry’s requirements - the J35 Draken was born.
The J35 Draken undertook its maiden flight in October 1955 and entered service with the Swedish Air Force in March 1960. Over 650 Drakens of various modifications would be built until the end of production, serving with Sweden until the late 1990s before being decommissioned. Apart from Swedish service, the J35 Draken also saw use with Denmark, Finland and Austria. The Austrian Air Force was the last operator to decommission the Draken in 2005, while some units are still in civilian use.
