Description

The ▃Ki-61-Ib Hien is a premium Rank II Japanese fighter with a battle rating of 3.7 (AB/RB) and 3.3 (SB). It has been in the game since the start of the Open Beta Test prior to Update 1.29. It costs 700 Golden Eagles.

Unlike its more maneuverable and agile counterpart, the A6M Reisen, the Ki-61 is more of what one would call an "energy fighter". Compared to the "Zero" it is faster, has a higher climb rate, and handles better at higher speeds. This captured version of the Hien has exactly the same stats and armament as the Japanese version. Armed with four 12.7 mm Ho-103 machine guns and plenty of ammunition, the Ki-61-Ib is a more than capable fighter. As a continuation of the Japanese army tree, the Ki-61 is the successor of the earlier Ki-43 Hayabusa. The Hien is faster, has a higher rate of climb, and features a better armament. Utilize these three aspects when facing planes like the Ki-43. In realistic battles, one of the major advantages the Ki-61-Ib has is its climb rate. The stat card may be misleading, but this plane can reach altitudes no enemies will be close to (unless of course, the enemy is another Hien). This allows the Hien to choose when and where it wants to fight. Instead of simply "turning and burning" the Ki-61 is very good at energy fighting, or Boom & Zoom. Once at a high altitude the Hien pilot may choose to dive lower to attack an enemy. If the enemy is not destroyed on the first pass, it is recommended to climb sharply and gain altitude. By doing this, the Hien sets itself up for another attack while not being in range of the enemy's guns.

Armaments

Offensive armament

The Ki-61-Ib (USA) is armed with:

• 2 x 12.7 mm Ho-103 machine gun, nose-mounted (400 rpg = 800 total)
• 2 x 12.7 mm Ho-103 machine gun, wing-mounted (500 rpg = 1,000 total)

Usage in the battles

The Ki-61's instrument panel.

The Ki-61-Ib utilized four 12.7 mm Ho-103 Japanese machine guns. Generally they are unreliable and it often takes hundreds of rounds to destroy an enemy plane. This is due to the lack of primer in the rounds themselves. 12.7 mm rounds fired by the M2 Browning may seem to do more damage because they have more primer which dictates how fast the round will exit the barrel. Due to this, it is necessary to get up close to enemies. Aim for the engine, pilot, or fuel tanks if the location is known. Remember to lead with these machine guns, as the rounds are not high velocity.

The Hien is best utilized as a multi purpose fighter. Although proficient at energy fighting, the Ki-61 is also generally average at standard maneuvers. It may lose turn fights with some enemy aircraft like the A6M2, but nonetheless it can still be used in multiple roles. The Hien is your standard "jack of all trades". It's not incredibly good at anything it does but it is even across the board. This allows the Hien pilot to choose what role he or she wants to play in the battle. One could play the reserved, high flying energy fighter, or the aggressive low flying dog fighter. The Ki-61 allows these choices.

Its armament is not so flexible, as the American captured version is unable to equip bombs or ground targets ammunition. Its weapons, four Ho-103 12.7 mm machine guns, are considered by many to be unreliable and unwieldy. However, with accuracy and shot placement, the large ammunition pool can work to your advantage.

If caught in a sticky situation, the Hien pilot may choose to do several things. Depending on your altitude, executing a rolling scissors or an overshoot may be a valid tactic. Try to make the enemy pilot feel pressured to disengage. Depending on the enemy's aircraft, use your speed to your advantage and try to get away. The most sure tactic would be communicating with teammates to ensure your assailant's death. Once tailed, the Hien pilot can "set up" an enemy by nosing up about 70 degrees so the entirety of the enemy plane is shown. At this stage, ideally your teammate is arriving to save the day.

History

In December 1943, the US Marine Corps landed at Cape Gloucester on the island of New Britain. After capturing the temporary Japanese airfield, the Marine Corps discovered a hidden Ki-61 Model 1Ko fighter (serial number 263) from the 68th Sentai produced in April 1943.

The aircraft had been abandoned by the Japanese due to a number of engine malfunctions which were not repairable in the field. The aircraft was meticulously inspected by officers of the US Army's Technical Intelligence and sent to Australia, where it was restored to airworthy condition and had USAAF markings applied to it. This is the aircraft we currently see in-game.
