Late in the war, after taking a pounding at the hands of powerful, heavily armed, and durable American aircraft, the Japanese Army wanted a fighter that could compete with heavy U.S. airborne iron on its own terms. In design at least, they certainly succeeded with the Ki-84. Japan's badly decimated aircraft industry, however, was not up to the task of producing the plane. Had the Frank not suffered from appalling manufacturing deficiencies, it certainly would have been one of the greatest prop fighters of the Second World War.
Fortunately for Air Warrior Frank pilots, the game does not model the failures of material and workmanship the actual Ki suffered. The Frank has a 1900 horsepower Homare engine in an airframe more than one ton lighter than the Corsair. This gives the Frank excellent speed - faster than even the Mustang at low altitudes - along with a good climb rate. The Frank can out-turn every plane in the Pacific except the Zero, at low speeds, and the P-38 at high speeds.
The Ki is lethal, sporting two 20mm cannon in addition to two machine guns, but its lethality drops sharply after 35% of its ammunition is gone. Nonetheless, the total ammo load on a Frank is substantial.
Most planes in Air Warrior come with distinct assets and limitations that dictate the way you should fight when flying them. The Ki, however, is so versatile that it appeals to energy fighters and turn-and-burn dogfighters alike. It's main deficiency against American planes is durability, but that is perhaps its only drawback.
Opinions vary widely over the values and vices of the Frank in full realism. Some call it, "the Focke Wulf of the Pacific," due to its mixture of great guns and speed, combined with its nasty departure characteristics. The Ki's fundamental structural limitations, compared to American fighters, become more of an issue in full realism. Whereas an American fighter can pull as many as 8 or 9 Gs briefly at high speed, a similar stress to the Frank's airframe would rip a wing off.
The Ki-84 is extremely fast - the fastest fighter in the Pacific at the low to medium altitudes where most battles take place in the online, network arena. In addition, the Frank is extremely maneuverable, particularly at speeds between 150-250 knots. At these speeds, only a Zeke can outturn it. Lastly, the Ki has good guns, an ample ammo load, and excellent range.
The Frank is not a sturdy aircraft. At high speeds you constantly run the risk of ripping its wings off in maneuvers, and its controls turn to mush above 350 knots. Also, the Ki will depart into violent spins if pushed beyond its low speed limits. Stalling this airplane when its wings are not parallel to the horizon is almost certain to induce a nasty spin.
Finally, with its radial engine and high parasitic drag, the Ki accelerates poorly, and bleeds energy badly - especially in straight, boom and zoom maneuvers.
Initially, most pilots would regard the Frank as an ideal scenario fighter due to its range, guns, ammo load, speed, and maneuverability. While it indeed possesses these attributes, the Ki is absolutely terrible at the extreme altitudes typical in scenario play. It can barely maintain level flight at 35,000 feet - a common height for combat air patrols in the better high altitude fighters.
Throttle back in nose-down turns, especially if you're entering the turn at high speed. Many novice Ki pilots tend to enter compressibility, over control the plane to compensate, and then rip the wings off when they regain control of the aircraft. Watch your airspeed in high speed tail chases, especially against American fighters. Again, compressibility is the enemy here; you will lose control over your plane before the pilot in the American fighter will. If you throttle back, or make constant, though slight, flight adjustments as you reach speeds of 375 knots and above, you can often stave off or delay the onset of compressibility.

| 2-20mm cannons | 240 shells | 1-550 lb. bombs |
| 2-12.7mm Machine Guns | 700 rounds | - |
The Ki is extremely fast and has excellent turning ability at low to medium altitudes. Above 20,000 feet, however, its performance attributes begin to steadily diminish.
Up to 20,000 feet only the Corsair and the P-38 climb better than the Ki-84. The Ki is faster than all Pacific theater types at low altitude, and only the Mustang is faster at medium altitude. In the thin air, however, the Ki is far from formidable.
Despite its impressive high speed numbers, low speed turning is what the Ki does
best. Only the Zero can do it better. In high speed turning, however, heavy
American iron can best the Frank easily.
