The Polikarpov I-16 in World War II


When Polikarpov I-16 was introduced into Soviet air forces in early 30th it was a revolutionary design. It was the world's first low-wing cantilever monoplane fighter with retractable landing gear to have attained operational status[1]. It was a backbone of VVS when Eastern front was opened in 1941. However at that point its performance potential was already exhausted and it was already planned to be replaced by a newer designs like Yak-1, LaGG-3 and MiG-3.

It was very small aircraft of 9m wingspan and 6.13m of length with rear weight bias making it difficult to fly and easy to fall into spin, also the recovery was easy. When British instructor had an opportunity to fly I-16, after landing the aircraft he was sweating heavily and commented "Let the Russians fly this airplane!"[2] I-16 was built in many variants. It engine was being constantly upgraded during from early 480 hp Shvetsov M-22 in type 4 variant up to 1,100 hp M-63 in late variants type 29. The armament was in constant evolution as well resulting in most heavily armed early war fighter aircraft.

The Polikarpov I-16 in Aces High II

The Polikarpov I-16 in AH powered by 1,100hp Shvetsov M-63 radial engine comes in 3 latest I-16 types 24, 28 and 29 depending on the armament. It is generally outclassed at Late War Main Arena by all means, however it still holds on its own against early war plane set. It is comparable in its performance to Bf-109E-4 and Hurricane Mk I and has a significant place in any early/mid war special event.

This plane can be seen as a mix of good climb and acceleration, great firepower and cockpit visibility, outstanding maneuverability for an early war design combined with a short loiter time and significant lack of speed even for an early war design.

Engine Power

The aircraft has very good climb performance for an early and stands on its own for even a mid war plane. The climb diagram is quite similar to that of Bf 109E-4 and A6M2, slightly better than Hurricane I over 12K and significantly better than similar period US planes P-40C/E or F4F. I-16 accelerates well for an early model plane and decelerates easily thanks to vast amount of drag induced by a huge radial engine.

Unfortunately you can say the same about its speed performance. I-16 is one of the slowest planes in AH. It is about 40 mph slower than Bf-109E-4, P-40C at 16K, about 20mph slower than Hurricane I at altitude. On the deck it has a similar speed to Hurricane I amd A6M2.

Another limiting factor is fuel consumption. I-16 has only 16 min military power of fuel extending it to around 24 min with drop tanks making them almost mandatory at MA (for fuel burn multiplier of 2.0). I-16 does not even come close in its loiter time to that of early period Hurricane I and with DT it is similar to that of its main opponent Bf-109E-4. So management of engine RPM and throttle is mandatory operational knowledge for every I-16 pilot and helps extend its limited loiter time to somewhat reasonable.

Short loiter time also brings a restriction for early Eastern front event designers - using high fuel burn multiplier values can significantly hamper already limited abilities of I-16.

Polikarpov I-16 has one of the best early war packages available. You should note that eastern aircraft have different characteristics in comparison to western counterparts. So these are several things you should remember when you consider a package both as a fighter and as a target.

  1. ShKAS MG guns have much higher rate of fire in comparison to western .303 MGs. The typical rate of fire for western MG is around 1,000 rpm while synchronized ShKAS gives around 1,600 rpm and non-synchronized 1,800 rpm. So type 24 package with 4 MG provides roughly same rate of fire as 6.8 0.303 MG i.e. quite close to that of Hurricane Mk I with half of the guns without harmonization issues giving high accuracy.
  2. 20mm ShVAK canon carrying 90 round of ammunition each has much better ballistics than early war counterparts Type 99 or MG-FF carrying 60 rounds each. The ShVAK canon is essentially the same canon used in later war La-5 and La-7 but with lower ammo load making it very heavy armament similar to mid-war period.
  3. The UBS MG has higher rate of fire of around ~1,000 rpm in comparison to ~850 rpm of .50 cal AN/M2.

There are three armament types available. All of them share two cowl mounted synchronized 7.6mm ShKAS MG with 450 rpg. Additionally each type provides:

  • Type 24
    2 wing mounted 7.6mm ShKAS MG, 900 rpg
    It is probably the most underestimated package as it consists of "only 4" MG. However considering the high rate of fire of ShKAS MG it more than reasonable early war package that is close to that of Hurricane Mk I and Spitfire Mk I. A short well aimed burst of fire would chop parts of even heavy bombers and good enough to deal with fighters.
  • Type 28
    2 wing mounted 20mm ShVAK canon, 90 rpg
    it is probably the best package available for any early war plane. It provides decent punch against both fighters and bombers. However it requires taking care of convergence. Having only 90 rpg you can't "spray and pray" and once you out of 20mm shells you have very limited fire power.
    Another important issue with type 28 package is its weight that somewhat hampers few existing good I-16 qualities like climb, acceleration and turn rate. Historically introduction of ShVAK canons reduced the turn rate from 15 to 18 seconds of a complete 360° circle.
  • Type 29
    1 synchronized bottom mounted 12.7mm UBS MG, 230 rpg
    It is somewhat similar to type 24, but provides arguable more firepower due to replacement of 2x7.6mm ShKAS with 1x12.7mm UBS and what is also important it has no convergence issue allowing to hit targets painfully and accurately at quite long distances.

Special note should be said about 6xRS-82 rockets. They are quite difficult to aim having a bad ballistics and high dispersion rates. At 200 yards they already drop below the lowest mark of aiming circle and probably should be used is salvo to get reasonable results against ground targets.

Historically RS-82 were used as air-to-air rockets as well similarly to later Luftwaffe's R4M. Fuses with delays of 2 to 22 seconds could be installed and used against bomber formations. They were successfully used for the first time at Khalkin Gol against bomber formations. During WW2 pilots considered them an effective weapon to break enemy formations[3],[4].

Unfortunately delayed fuses aren't available in AH and only way to bring down a bomber with a rocket is to hit with it directly. It can be done against big bomber target with reasonable probability and accuracy from ~200 yards but the risk of being shut down in such an attack is too high.
