General info

The Ki-43-III otsu Hayabusa in the garage.

The Ki-43-III Otsu Hayabusa is a Rank III Japanese light fighter with a battle rating of 4.3 (AB), 4.0 (RB), and 4.7 (SB). It was introduced in Update 1.45 "Steel Generals".

The main purpose, usage and tactics recommendations

General play style

The Ki-43-III Otsu starts off as a rank three aircraft in the Japanese Army Air Force line. Like its tier two brethren, it is an extremely maneuverable and lightweight aircraft. It has exceptional climb and roll rate making it a fairly hard target to hit in the hands of a skilled player. The trade-off, however, is its extremely fragile nature - a good hit even from a plane equipped with rifle-caliber guns could do some serious damage if one doesn't push the plane to its limits in any of the game modes. On the other hand, the rather modest pair of fuselage-mounted 12.7mm Ho-3s of the Ki-43-II have been replaced with a pair of the hard-hitting Ho-5 20mm cannons, which for its battle-rating gives the Hayabusa power it needs to take down anything it opposes. Like many of the Japanese fighters, dog-fighting is the key to staying alive. By using the combat flaps and throttle in a optimal manner, this aircraft can get behind nearly every opponent it meets in a low to mid altitude dog-fight. With a modest ammo load of 300 rounds, trigger discipline is important here. It is best to get up close (500m-200m is optimal) and then let off several short bursts, firing until the enemy is critically damaged or killed.

Vehicle characteristics

Like the Zeros, the Ki-43 is exceptionally light and maneuverable. Unlike the Zeros, the Ki-43 has a ridiculous roll rate making it the closest one can get to playing an arcade-esque plane in RB.

Unfortunately, this comes at a cost. At 4.0 BR the Ki-43 sees primarily American planes which are far faster in both level flight and dive while having significantly better armament. Evading fire becomes difficult when facing planes such as the P-47N-15 which has x8 M2 Browning .50cals that are extremely deadly and have a ridiculous volume of fire.

As such, the Ki-43 is almost entirely dependent on siphoning kills from unwary pilots or simple pilot error which makes it quite a difficult plane to play.

Tactics

When using the Ki-43-III Otsu Hayabusa, do remember this plane can easily out manoeuver anything it may face. Do not try to go head on with enemy planes as a single round can damage your plane.

Specific enemies worth noting

Most Allied opponents at 4.0 BR can outrun the Ki-43 with ease. Most concerning are planes such as the P-47D/N or F4U Corsair, as both planes are over 50mph faster on the deck and also possess exceptional .50cal armament. Use the Ki-43's maneuverability to dodge shots and try to slowly drain the energy of your opponent and force mistakes.

Counter-tactics

When facing the Ki-43-III Otsu Hayabusa do remember that it is very manoeuverable and that it can easily out turn what it faces therefore try to apply Boom and Zoom tactics against a Ki-43-III Otsu Hayabusa.

Pros and cons

Pros:

  • Excellent rate of climb.
  • Extremely manoeuvrable.
  • Quick roll rate.
  • Good armament.
  • Decent ammo capacity.
  • Easy to fly.
  • Low stall speed.

Cons:

  • Lightly Armoured.
  • Can catch fire easily due to the lack of armored fuel tanks.
  • Can feel a bit like a paper airplane handling-wise.
  • Extremely slow, at 507 km/h on the deck.
  • Poor high-alt performance.
  • Energy retention and dive speed is abysmal.
  • Wing rips can happen very easily if one performs high speed maneuvers (~11 G).

Modules and improvements

The stock 20mm cannon belts are a pain. Research the "offensive 20mm belts" fast. Otherwise there is not a lot necessary to upgrade, mainly performance modules. The engine and compressor modules do wonders. Payload unlocks should be considered last. The Ki-43 is a fighter and not a ground attacker like the B7A2.

History of creation and combat usage

The Ki-43 was fairing poorly against allied aircraft by 1944. A new version was constructed at an attempt for better performance. The Ki-43-III is very similar to the Ki-43-II Hayabusa except for its engine. It was replaced with the far more powerful Mitsubishi Ha-112-32/42 engine. The aircraft was also fitted with a pair of 20mm cannons. The last variant of the Ki-43, (the Ki-43-IIIc) was intended to protect main land japan from B-29s. The war ended before the aircraft could ever be produced.
