 Although the J21 can be set on fire rather easily due to its centrally located fuel tank, it is often possible to put out the fire by diving very steeply and fast. This creates enough of a slipstream around the fuselage to often put out the fire.
-A enemy worth noting is the F-82E which is equipped with 6 12.7 mm M3 Browning machine guns which could provide a formidable foe that could take out the J21A quickly with just a few bursts, and its payload is superior to the J21 variants, which could result in a quick death when going head on with one.

Another plane of interest that needs not be ignored is the XP-50, which has an airspawn and will most likely have an energy advantage over you, be careful while dealing with such planes.

-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.
+Overall, the J21A was designed (and should be used) as an interceptor. One excellent tactic is to climb at about 20 degrees until reaching 4,000-5,000 m and operating from that altitude in a boom-and-zoom role. This enables the J21A to use its excellent dive speed and heavy armament to maximum effect.
-Climb to about 1,000 m then use boom and zoom tactics to pick on enemies. Due to the powerful nose-mounted armaments, head-ons are quite easy.
+Another effective tactic is to fly level and fast at medium altitude 2,000-3,000 m and act as a support fighter, assisting team mates who are overwhelmed by picking off some of their opponents in hit-and-run attacks. While the J21 can maneuver quite well (especially with combat flaps) it is not advisable to do this except as a last resort because the aircraft bleeds speed very rapidly. Also, this can expose the J21's engine (mounted in the rear of the aircraft) to and an enemy, allowing him the opportunity to knock out the J21's engine or hit its fuel tank (centrally located between the cockpit and the engine). This is another reason to avoid running away from an opponent, except when you can dive faster than the enemy or outclimb him. Many planes at the J21's level can keep up with it, although many also cannot. As long as you know your opponent and their capabilities, you can use the J21 very effectively.

The go-to tactic versus a P-47 is to turn with it in order to get on its tail then shred it with your guns.

-The SAAB 21 rose from the drawing board in anticipation of World War 2. The development of this aircraft came with the need to develop a national fighter without having to rely on foreign designs like the Re.2000 and CR.42. The Saab 21's unique twin-boom layout, offering exceptional pilot visibility and easy maintenance, was chosen and fitted with a modified German Daimler-Benz DB 605 engine.

-The J21 series is arguably the most iconic propeller-engine aircraft to ever come out of Sweden. For the time, they were underpowered, slow aircraft that were outclassed by nearly all opponents it could have faced. Its distinctive twin-boom, rear-engine fascia is easy to recognize and its performance is nothing to scoff at either, though the climb rate is poor and the engine overheats quickly when using WEP. 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.

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 Bf 109s are noteworthy adversaries whose strengths change with the model. The F-1 and F-2 will turn better than you and climb quite as well as you do. the F-4 is almost a hard counter depending on if it runs gun pods. Without gun pods, the F-4 out speeds, outclimbs, outturns and out accelerates the J21, outclassing it in every way. But since most F-4s carry gun pods, their decreased performance helps even the odds. Boom & Zoom the F-1 and F-2, head on the F-4 only as a last resort.

 * 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
 * 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

 After further work, three full prototypes were constructed for testing, two of which were fully functional. In July 1943, the prototype of the SAAB 21 first took to the skies for its maiden flight. Production of the SAAB 21 began some time after its maiden flight, with the first aircraft reaching their units in December 1945.
 Overall, over 50 J21A-1s were produced before production of the first model stopped by December 1946. In total however, close to 300 piston-engined J21s of all variants were produced before the production run of the type ended in 1949.
 Due to the J21's introduction to service coinciding with the dawn of the jet age, the type didn't remain in active service for too long. In fact, the J21 was retired in 1954 - some ten years after its initial introduction - and its only operator remains the Swedish Air Force.

-The J21A-1 is the first production series SAAB 21, quite sluggish but a heavily durable fighter. It has a top speed of 640 km/h, courtesy of the Daimler-Benz DB-605B engine; However, the speed and manoeuvrability are not the most impressive characteristics of the aircraft: it's the weaponry it comes armed with. A total of four 13.2 mm [[Akan m/39A (13.2 mm)|Akan m/39A]] and a 20 mm [[Akan m/41A (20 mm)|Akan m/41A]] makes it a heavy firepower-reliant fighter able to eliminate any enemy aircraft with ease.
