{{main|AN-M64A1 (500 lb)|G.P. Mk.I (1,000 lb)|H.C. 4,000 lb Mk.II (4,000 lb)}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* 9 x 500 lb AN-M64A1 bombs (4,500 lb total)
* 6 x 1,000 lb G.P. Mk.I bombs (6,000 lb total)
* 1 x 4,000 lb H.C. 4,000 lb Mk.II bomb + 2 x 1,000 lb G.P. Mk.I bombs (6,000 lb total)

== Usage in battles ==

Climbing high to around 10 kilometres will save you from most predators and AA fire in both AB and RB as the Canberra has one of the best climb rates and high-alt performances in the game. Watch out for the [[Me 163 B|Me 163]] and [[Ki-200]], who can climb to you easily thanks to their Rocket Engines. A common strategy by Canberras (and B-57s, as they are the same airframe) is to head to one base, drop all payload on such base and then running for their lives. Using the 6 x 1,000 lb payload is recommended for usage on bases while 1 x 4,000 lb + 2 x 1,000 lb payload works best when used on airfields.

Since the move to 8.3, the Canberra does not perform very well at all. Its primary advantage, being able to outrun most fighters, was lost following its move to 8.0 and 8.3. It is best advised to drop any/all bombs you have on the First Base you see. It is possible to evade contact by flying out to the side, but as RADAR becomes more prevalent it is not recommended to do so. Wasting Time over the target zone, is in essence a liability.

=== Pros and cons ===


'''Pros:'''

* Good stock engine power
* Good stock acceleration speed
* Powerful airbrakes
* Good top speed for such a large aircraft
* Decent payload
* High service ceiling(max. altitude)
* Great climb rate

'''Cons:'''

* May rip wings by going straight for a while without intelligent use of air-brakes
* Large target
* Likely to be a big target for fighter aircraft with an air-spawn
* BR 8.3, which means you will be caught by all jets that you face (due to Matchmaking primarily being 7.7-8.7, 8.0-9.0).
* Requires quick thinking to outmanouevre an enemy that is on you.
* Due to being one of the first contacts spotted, you will almost always be engaged first.
* First few fights will be running to a base, bombing the base and ending up dead by enemy jets.

== History ==

The Canberra B Mk.2 was created in 1949 to replace the Mosquito fast bomber. It was designed to have outstanding high altitude performance and speed, being unparalleled for 10 years. Despite the RAF originally expecting the Canberra to be obsolete within a few years of entering service, so much so that work to develop a replacement (eventually leading to the TSR-2) was started before it had even entered service, it would go on to be one of the RAF's longest serving aircraft. The Canberra remined in front line service with the RAF until its retirement in 2006, some 55 years after it first entered service (although it spent a lot of that time in the photo-reconnaissance role, as opposed to its original purpose as a bomber). The Canberra was replaced in the strategic bomber role by the Valiant (and other V-bombers), and in the strike role by the Buccaneer (following the cancellation of the TSR-2 programme). It established a world altitude record of 21,430 m in 1957 and was the first jet-powered aircraft to make a non-stop transatlantic flight.

=== In-game description ===
Whilst the United States and the Soviet Union were, in many ways, running ahead of Britain during the early development of jet fighters, Britain would at least keep up if not forge ahead with its very first jet bomber – the legendary English Electric Canberra.

The origins of the Canberra lay in 1944 when the Air Ministry called for a replacement for the de Havilland Mosquito in the light bomber role – a fast, agile tactical bomber was required by RAF Bomber Command to move into the jet age. English Electric set to work under Chief Engineer WEW Petter, who envisaged a bomber built around straight wings of a large area, and two of the new Rolls-Royce Avon jet engines. The prototype first flew in May 1949, with Typhoon-ace Roland Beamont at the controls. The Chief Test Pilot remarked that the aircraft was practically free of vices and possessed an agility that was reminiscent of a fighter rather than a bomber.

After various modifications were made, including the addition of a glass nose for a bomb aimer, the first production variant – the B Mk.2 - entered service in 1951 with No.101 Squadron. The Canberra was able to reach speeds of some 560 mph and reach heights of 48,000 feet whilst maintaining the capacity to carry 6000 lbs of ordnance. A series of modified Canberra B Mk.2s set a succession of world altitude records, culminating in August 1957 with a staggering 70,310 feet. It was a Canberra that saw victory at the Last Great Air Race from London to Christchurch in 1953. With a range of approximately 2600 miles, the Canberra was considered a tactical rather than a strategic bomber.

The Canberra was popular with its aircrew due to its performance, popular with ground crews due to its relatively simple maintenance schedule and also popular with Command due to its relatively low cost. Over 400 Canberra B Mk.2's were built until uprated engines led to the development of its successor, the B Mk.6, which entered service in the summer of 1954. As squadrons received the newer model, the now older B Mk.2 saw service with the RAF in Germany, Cyprus and the Far East, although the variant did serve successfully in the Suez Crisis of 1956. A small number of export variants of the B Mk.2 also saw service with the United States as a template for building under license as the Martin B-57, Australia and Venezuela.

=== Survivability and armour ===

The Jaguar GR.1 has no armour plating or armoured glass. The entire wings of the Jaguar GR.1 are made up of fuel tanks, along with most of the upper fuselage, with flight controls being exposed in the "spine" of the aircraft. The two engines take up a small amount of room in the very rear of the fuselage.

== Armaments ==
=== Offensive armament ===

{{main|ADEN Mk.4 (30 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 2 x 30 mm ADEN Mk.4 cannons, belly-mounted (150 rpg = 300 total)

=== Suspended armament ===

{{main|Mk.M1 (540 lb)|G.P. Mk.I (1,000 lb)|AIM-9G Sidewinder|CRV7 M247}}

The '''''{{PAGENAME}}''''' can be outfitted with the following ordnance:

* Without load
* 2 x AIM-9G Sidewinder missiles
* 76 x CRV7 M247 rockets
* 8 x 540 lb Mk.M1 bombs (4,320 lb total)
* 8 x 1,000 lb G.P. Mk.I bombs (8,000 lb total)
* 2 x AIM-9G Sidewinder missiles + 38 x CRV7 M247 rockets
* 6 x 540 lb Mk.M1 bombs + 2 x AIM-9G Sidewinder missiles (3,240 lb total)
* 6 x 1,000 lb G.P. Mk.I bombs + 2 x AIM-9G Sidewinder missiles (6,000 lb total)

== Usage in battles ==

As a Strike Aircraft, the Jaguar is best suited to going after Ground Targets. Equipped with up to 8 1000 pound bombs, it shines as a Ground Attack Aircraft in Ground RB and is a very dangerous aircraft for Tanks. However, equipped with the Air to Air Missiles (AIM-9Gs, which, are admittedly are not perfect, but since it was intended as a Ground Strike, they were intended for self defence) and a Pair of our friends, the ADEN 30mm Cannons, it is also a very real threat to any Fighters that find a Jaguar behind them, or indeed ahead of them and closing fast. The main strategy is to act as a support aircraft, rather than flying Solo against enemy Fighters. A Rather Handy Drag Chute and Arrestor Gear is provided, though it is not advised to use a Jaguar alongside a Carrier, as the Arrestor Gear was only intended for situations where the normal Wheel and Air Brakes had failed.

However, you cannot forget in the Jaguar that you are a glorified Strike Aircraft. You only have 2 Missiles at most, and 300 Rounds, to which Trigger Discipline, is as always, a must. Again, engaging Fighters is not a problem, and the Jaguar is very agile without a lot on bombs slung underneath.

'''Enemies Worth Noting:'''

'''MiG-21s:'''

As a member of NATO teams you can and will face MiG-21s. The F-13/J-7II (Chinese) are a pair of dangerous opponents, with their 23mm guns, but the Missiles are not fatal. They are the equivalent of AIM-9Es, and track badly if you are at long range or are turning. The SMT/MF variants are much more a threat. With R-60 Missiles, they are to be feared and respected. ,

'''Phantom/F-4s'''

Again, F-4s are very very dangerous. However, unlike the MiG-21, they get access to far more Ammunition for Guns. They also get access to SARH Missiles, as well as AIM-9J Missiles on the E/EJ variants.

'''Any other Fighters:'''

The best rule of thumb is to play safe, if you are flying as a Ground Strike Aircraft, but usual rules apply when engaging enemy fighters.

== History ==

The Jaguar was a joint program between the British and French to develop a cheap subsonic trainer and light attack aircraft. The British and French bought a total of 403 aircraft with Britain receiving 203 of the aircraft. Other exports include to the Indian Air force (160 total aircraft ordered ), The Royal Air force of Oman (26 total aircraft ordered), The Ecuadorian Air force (12 total aircraft ordered) and the air force of Nigeria (18 total aircraft ordered). The Jaguar was used in several military conflicts in countries such as: Mauritania, Chad, Iraq, Bosnia, Pakistan and The Chenepa war but most notably it saw service in the 1990 Gulf War during Operation Desert Storm, where it was used to destroy Iraqi artillery and missile positions. During the Bosnian bombing campaign of 1995 Jaguars of the 41 squadron carried out the first raids in Europe since the second world war. During the Bosnian airstrikes jaguars were fitted with laser designators and would laze Bosnian-Serb forces for RAF Harriers to strike. These re-fitted more modern Jaguars were re-designated as SEPECAT Jaguar GR.1 B and is not the same as the one we currently have in the game, although it is possible that Gaijin will add these in the future.

{{Break}}
The '''{{Specs|name}}''' is a rank {{Specs|rank}} Swedish fighter {{Battle-rating}}. It was introduced in [[Update 1.95 "Northern Wind"]] along with the rest of the Swedish air tree.

== General info ==
=== Flight performance ===

The J21 series is arguably the most iconic propeller-engined aircraft to ever come out of Sweden. For the time, they were underpowered, slow aircraft that were were outclassed by nearly all opponents it could have faced. It's distinctive twin-boom, rear-engined facia is easy to recognize and its performance is nothing to scoff at either. The [[Akan m/39A (13.2 mm)|Akan m/39A]]'s are some of the most effective non-cannon aircraft weaponry in the game, boasting superior aspects to even the famed [[M2 Browning (12.7 mm)|M2 Browning]], specifically in terms of raw stopping power and muzzle velocity. The [[Akan m/41A (20 mm)|Akan m/41A]]'s are quite powerful as well. The challenge for the pilot is to manoeuvre this aircraft into a solid shooting solution which can be difficult especially against more agile aircraft. Although suffering from a relatively low rip speed, skilled and new pilots can use this somewhat to their advantage, mainly by diving on opponents and climbing again, although this shouldn’t be attempted at extreme speeds.

=== Offensive armament ===

{{main|Akan m/41A (20 mm)|Akan m/39A (13.2 mm)}}

The '''''{{PAGENAME}}''''' is armed with:

* 1 x 20 mm Akan m/41A cannon, nose-mounted (140 rpg)
* 2 x 13.2 mm Akan m/39A machine guns, nose-mounted (350 rpg = 700 total)
* 2 x 13.2 mm Akan m/39A machine guns, wing-mounted (325 rpg = 650 total)

The '''automatkanon m/41A''' is essentially a slower firing [[Hispano 404 (20 mm)|Hispano 404]] with more ammunition, with all the advantages and disadvantages that come with it. While one might think that the slower firing speed is a disadvantage, it is just high enough to still be effective and is very beneficial for conserving ammunition. It is important to note that when stock, the cannon is very inaccurate and overheats quickly, but becomes quite accurate after modifications.

The complimentary '''automatkanon m/39A''' heavy machine guns are, as mentioned previously, arguably the best non-cannon weapons in the game. Their high muzzle velocity, very high fire rate and reasonable accuracy allow them to saturate the sky with lead. The higher calibre of 13.2 mm allows for more stopping power than the typical 12.7 mm and converts them from just being a nuisance to a threat to be heeded. It is interesting to note that due to their HEF-T rounds, they technically fall under the category of "cannon", as normally exploding rounds typically start at 20 mm.

== Usage in battles ==


For pilots just beginning to learn this aircraft's flight characteristics, it is best used as a support aircraft, it is too slow to take into dives reliably and suffers from Yak-like rip speeds, without any of the benefits that the Yaks have in agility. For pilots with more experience, you can successfully push this aircraft to its limits and beyond and eliminate lesser experienced pilots in more agile aircraft or even other more experienced pilots through strong counter-manoeuvres.

==== Specific Enemies Worth Noting: ====

* '''[[P-47D-25]]/[[P-47D-28|28]]:''' The high-speed Thunderbolts are a menace in any game mode. They are some of the fastest things in the bracket and sport an octet of the late M2 Brownings that will set you ablaze in a few short bursts. While they are already quick at medium altitudes, they become even faster at high altitudes, easily blitzing past the poor J21. However, they have incredibly poor turn rates and climb just as badly. The go-to tactic versus a P-47 is to turn with it in order to get on its tail then shread it with your guns.
* '''[[M.B.157]]:''' The 157 is one of the worst enemies you can come across as it is basically a Thunderbolt that can turn and climb. Its ludicrous speed along with excellent climb rate and its above-average manoeuvrability make for an enemy that you cannot face in a 1-on-1. Your best bet is to try to head-on it if you can manage to do so. The one Achilles heel of the 157 is its low ammunition count, so try to get it to waste as much ammo as possible before it needs to disengage. At this point, you can either try to gun it down or attempt to regain altitude so you may catch it later.
* '''[[Bf 109 (Family)|Bf 109 F series]]:''' The F series of 109's are noteworthy adversaries whose strengths change with the model. The F-1 and F-2 will turn better than you and climb quite well but you are, the F-4 is almost a hard counter depending on if it runs gunpods. Without gunpods, the F-4 out-speeds, outclimbs, outturns and out-accelerates the J21, outclassing it in every way. But since most F-4's run gunpods, their decreased performance helps even the odds.

=== Pros and cons ===


'''Pros:'''

* Very stable, does not stall in level flight even with the throttle set to zero
* Engine protected from head-on attacks
* Highly effective and accurate armament layout that will tear through enemies like paper
* Can take quite a few hits and still fly reasonably well
* Very high energy retention
* Easy to land thanks to its tricycle landing gear
* Rear-mounted engine makes head-ons safer (can't be hit during head-on)

'''Cons:'''

* Pusher aircraft, engine mounted facing rear, can be hit by tailing aircraft
* Fuel Tanks can take damage if you pull up from a dive on an enemy plane
* Required to set convergence due to wing-mounted machine guns
* Agility is quite poor, it is subpar to most aircraft
* High repair cost
* Engine overheats during takeoff, and during flight at WEP, even with full modifications.
* Very low rip speed - cannot push past 640 km/h (400 mph) without threatening to rip off wings

== History ==

The SAAB 21 is a twin-boom pusher fighter and attacker designed by the famed Swedish engineer Frid Wänström (pronounced "Vanstrom"), who also worked on the SAAB 29 ''Tunnan'', 32 ''Lansen'', 35 ''Draken'' and 37 ''Viggen''. In the anticipation and wake of World War 2, Sweden was concerned over its neutrality policy coming under threat by the other European countries, specifically hostile ones such as Nazi Germany. In order to deter belligerent forces and potential aggressors, the Swedish Air Force created a major plan to modernize their fleet, which included the import of foreign models such as the Italian [[J11|CR.42]] and [[J20|Re.2000]] as a stopgap measure.

Meanwhile, Swedish corporation SAAB began studying designs for the possible development of a new, high-performance fighter aircraft. Most of the designs were based around the Bristol Taurus two-row 14 cylinder radial engine developing around 1,000~1,100 horsepower. The most promising design was a twin-boom pusher layout and made use of many new features unfamiliar to the SAAB technicians and engineers at the time, but was able to compete with the other fighter aircraft at the time while also maintaining several advantages such as a heavy amount of nose-mounted armament and superior pilot visibility, along with ease of maintenance. The design was kept dormant until 41, as Sweden was beginning to see that it would not be able to procure improved foreign models as a result of the war, they started another rearmament program to adopt advanced indigenous fighter aircraft.

Accordingly, SAAB blew the dust off of their old twin-boom design and set to work. Earlier on, it was decided to replace the Bristol Taurus with an American Pratt-&-Whitney Twin Wasp, but this was changed when the engine manufacturer ''Svenska'' was requested to provide an alternative engine, which was difficult due to the time constraints. Thus, they decided that a licensed engine would be the best course of action. The legendary German Daimler-Benz DB 605 that powered many famous designs was chosen and modified to fit Swedish needs. Three prototypes were completed and its maiden flight was completed in 1942.

The type was delivered in 1945, and a total of 300 models were produced.
