General info

Flight performance

The MiG-17AS is powered by the Klimov VK-1 jet engine, the same as the engine found on the MiG-17. This engine performs well at higher altitudes, and affords this vehicle much better high-altitude flight characteristics than its American counterpart, the F-86. This also means that the MiG-17 performs much better in vertical manoeuvres than many other aircraft. The engine also gives this vehicle very good energy retention and a high climb rate. At high speeds (>900 kph), the aircraft experiences compression and loses roll and pitch authority.

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.

Armaments

Offensive armament

The MiG-17AS is armed with:

• 1 x 37 mm N-37D cannon, chin-mounted (40 rpg)
• 2 x 23 mm NR-23 cannons, chin-mounted (80 rpg = 160 total)

The Nudelman N-37D was a 37 mm autocannon which replaced the Nudelman-Suranov NS-37 autocannons. The N-37D was 30% lighter than the NS-37, but to lighten the load, a sacrifice was made causing a 23% drop in muzzle velocity in comparison. Even with the loss of muzzle velocity, this autocannon can still fire at 400 rounds per minute which equates to just over six per second, emptying the belt in just over 7 seconds if the firing button is continuously held and the gun does not jam. The continuous fire of this weapon should not be attempted as only one or two rounds is enough to take down the largest of aircraft, though a dodging fighter may take a few more rounds before one connects.

The Nudelman-Rikhter NR-23 was a 23 mm autocannon which was widely used on many Soviet aircraft. The NR-23 has a faster muzzle velocity over the N-37D by 200 meters per second, firing them at the same time will not result in them landing in the same place as the N-37D will begin to drop sooner. Firing at around 900 rounds per minute, the NR-23 can unload a good amount of ammunition downrange, however, with a limited supply of only 80 rounds per gun, it is best to fire in small bursts when the pilot has a good gun solution. Firing in "hopes" to hit the target will result in many missed and wasted shots and may very well cause the MiG-17AS to go dry just when those rounds are needed the most.

Suspended armament

The MiG-17AS can be outfitted with the following ordnance:

• Without load
• 2 x 250 kg OFAB-250-270 bombs (500 kg total)
• 2 x S-21 unguided rockets
• 2 x R-3S air-to-air missiles

Though built as a fighter-interceptor the MiG-17AS has the suspended ordnance option to actually take on a multi-role function. The MiG-17AS can function also as a fighter-bomber, fighter-attacker as well as a fighter-interceptor. To fulfil the bomber role, the MiG can be outfitted with two 250 kg bombs, though not enough to put a dent in an enemy base, these bombs are a great option for strategic bombing of vehicles or anti-aircraft artillery which may be a bit more spread out. These one-off or mobile targets are difficult for the higher up bombers to hit, but a fast and nimble strategic fighter-bomber can get in low and deliver the ordnance on to the target more efficiently.

As for the fighter-attacker role, the S-21 unguided rockets come into play. These unguided rockets are best used against ground-based tanks or high altitude bombers. Since the rockets are unguided, they work best against slow-moving targets and firing at a relatively short-range to endure positive contact either crippling the enemy vehicle or destroying it. The S-21 is a fire-and-forget rocket in that once it takes off, there is nothing more to do than let it reach its destination. At this point, the fighter can take evasive action or set up for another run if there are any rockets available to shoot.

For fast-paced air-to-air combat, the MiG-17AS can be outfitted with two R-3S missiles (reversed engineered AIM-9 Sidewinder also known as the Vympel K-13 or NATO AA-2 "Atoll"). This missile works best when flying behind the target aircraft to allow the system enough time to gain a lock. Once the lock is achieved, the missile can be fired. It is best to fire between 1 and 1.5 km from the target to allow for the least amount of reaction time and potential for evasive action on the enemy aircraft's part. Firing a missile from a greater distance is possible, however, the more that the enemy fighter can react to the missile launch, the better the odds are that they will be successful in evading the missile. If the missile is evaded, all is not lost, many times the enemy fighter had to perform several energy bleeding manoeuvres to evade the missile which may ultimately set them up for the MiG-17AS pilot to close in and eliminate the target with their 37 mm and 27 mm autocannons.

Usage in battles

Against enemy aircraft

The MiG-17AS has much better high-altitude flight characteristics most planes at its rank, so it is best played in higher-altitude dogfights. Nearer to sea level, the competition will have better engine performance.

This vehicle performs much better in vertical manoeuvres than many other aircraft, and such manoeuvres may be employed to cause an enemy aircraft to stall, giving the player an easy kill. But make sure that there are no other enemies nearby before attempting a low-speed stall manoeuvre.

The engine also gives this vehicle very good energy retention and a high climb rate. However, the plane begins to compress at high speeds, and aiming may become difficult. Watch out for this during diving attacks.

So, this plane is well-suited for medium-speed dogfights, where it can utilise its energy retention and good turn rate against enemy aircraft. In addition, luring enemies to slow speeds will allow the MiG-17AS's air-to-air missiles to better track and destroy them. (In practically all other cases, the poor-tracking missiles will struggle to keep up with a fast-moving, turning enemy.)

As for cannon armament, the MiG-17AS has three high-caliber cannons. This may sound perfect at first glance, but the armament setup on this plane does create difficulties on further consideration. First of all, these cannons are all slow-firing, and it is not uncommon that a fast-moving enemy will slip between cannon shells and avoid destruction. Also, the shells have a fairly low muzzle velocity compared to that of other jets at this rank, and have quite a noticeable drop. Combined with the slow firing speed, this makes aiming difficult at the best of times, and extremely challenging at ranges over 400 m. But as if all of that wasn't enough, the cannons are mounted below the nose of the plane, making aim difficult for players inexperienced in flying with this gun positioning. Furthermore, all three cannons have quite low ammo counts, so trigger discipline is key. All in all, this vehicle's guns are certainly not its strong point, but keep in mind that the aircraft's admirable flight characteristics can more than make up for this weakness: when the enemy is stalled out in front of this aircraft, its guns are more than enough to guarantee the kill.

Against ground targets

The MiG-17AS has the option to mount 2x250 kg bombs. However, these bombs considerably harm the vehicle's flight performance, and have quite low destructive power. Using them against armoured ground targets is often difficult.

In most cases, a better option is to use the 2xS-21 air-to-ground missiles available to this aircraft. These each contain a very good 9.95 kg of TNT, and may be fired separately. They also have quite respectable penetration, and will be able to penetrate the roof armour of many of the tanks that this vehicle might face in ground RB. They also have a decent velocity, and are easier to aim than bombs.

History

The Korean War showed that the MiG-15 and MiG-15 bis fighters were able to battle any aerial opponent at least on equal terms. The MiG-17 was a further development of the MiG-15 design that had proven itself so well. It was decided to increase the aircraft’s speed by increasing the sweep of the wing and the fuselage being lengthened to maintain the centre of gravity. The MiG-15 and MiG-17 show almost no differences at first glance. The prototype of the MiG-17 was even called the MiG-15bis45. However, only the frontal parts of the fuselage are the same, from the air intake to the wing, if you don’t count the landing headlight that had been moved to the left-wing and some minor details.

These aircraft are different in every other way. It is easy to see the main differences when you look from above. By comparing the side profiles, you can see that in addition to the difference in fuselage length there are differences in the tail fin and an additional ventral fin which allows you to immediately tell the MiG-17 apart from the MiG-15. The upper part of the fins and the rudders of the aircraft are different, the juncture between the fin and the stabilizer fin also differs, but this can only be seen close up. The wing sweep of the stabilizer fin was also increased and there were also changes to elevators. The air brakes also differ in shape and size. The depth of the housing was decreased, so a cigar-shaped cowl was created to hide the cylinder. There were very significant changes to the wing. Apart from an increased wing sweep, a leading-edge break appeared and the tips became rounder, which helps differentiate the aircraft when looking at them from above or below. While the Mig-15 had two aerodynamic ridges on the top surface of its wings, the MiG-17 had three.

The change in the shape of the wing led to appropriate changes in the construction of the flaps. The new geometry of the main landing gear legs required for the cover to be altered. The structure of the canopy also saw some changes. However, the first versions of the MiG-17 had the same canopies as the MiG-15 bis. Apart from changes to the design of the canopy framing (which is not actually that noticeable from afar), a rear-view mirror was introduced that would allow the aircraft to be recognized from further away. There were no significant changes to the cockpit. Overall, the MiG-17 looks even more aesthetically pleasing and streamlined than its predecessor.
