The once legendary aircraft was given a series of nerfs that turned it into a Japanese P-47 like aircraft. The Ki-87 has poor energy retention in very sharp turns, a lackluster roll rate, and a sluggish feel. The Ki-87 has issues with overheating on WEP, and you'll need to use manual engine control to operate this plane. All these flaws mean nothing to an experienced pilot, as the Ki-87 has the most fearsome armament of the super props. The cannons have excellent velocity, and usually one shot everything, and bombers fear you like the plague. the Ki-87 can reach amazing speeds in dives, and you can use tactics to force head-ons with many opponents.

The Ki-87 makes use of a Turbo-Supercharger. What this means is that your plane won't suffocate to death at high altitudes, so you can keep your engagements at high altitudes. Planes like the Yak-3, Corsair, and Bf 109 will be outclassed by the Ki-87 because of their poor high altitude performance. It is important to note that the Turbo Supercharger is not controlled by manual engine control, so you won't need to worry about adjusting your supercharger gear or turbocharger.

Using WEP the Ki-87 is able to climb to just over 5,500 m in five minutes, a strong climb rate. Bombers spawn in at 3,000 m so you can quickly climb above for positional advantage for booming and zooming. If the Ki-87 retains momentum from the dive and engages the targets, it will be able to climb back up to the operational altitude it was before engaging the enemy. It is recommended to take the minimum load of fuel, and set your guns targeting to 500 and turn on vertical targeting. You should run the tracer belts for your 30mm rounds and the universal rounds for your 20mms.

The Ki-87 is also a great silver lion maker. It has 520% lion reward calculator, and it also has a pretty low repair cost. The Ki-87 is rather expensive however, sitting at a price of 6080 GE. However, the plane is very much worth your time.

For landings, slow to at least 300 km/h (180 mph) before dropping the main gear and 250 km/h for flaps. Ideally, be about 50 m in altitude at the end of the runway and hold 200 km/h until touchdown.

The flight performance feels slow, sluggish, yet powerful. The turning and energy retention is not good either. This plane also has overheating issues. to solve performance issues, it's always best to go for a side climb, especially when in uptiers! The plane dives insanely well. The Turbo Supercharger will keep the plane's performance up while at altitudes above 5000 meters.

Japanese rank IV aircraft are typically armed with a respectable array of guns, and the Ki-87 is no exception. Although the 20 mm Ho-5's are nothing to write home about, the 30 mm cannons are some of the most feared, respected and deadly weapons in the entire game. When armed with the ''Tracer'' belt, the Japanese 30 mm cannons have a muzzle velocity that surpasses even the M2 and M3 Browning .50 cal HMG's at a staggering 920 m/s, and when combined with the high explosive filler and large calibre, these beasts will make short work of any aircraft that's unfortunate enough to end up in their crosshairs.

The usual issue with 30 mm cannons on WW2-era propellor planes - that being their lack of sufficient ammunition capacity - is notably absent on the Ki-87, which mounts 150 round per gun instead of the usual 60 seen on other aircraft like the [[Ki-84 hei]] and [[J7W1]]. Although this increased ammunition capacity is indeed wonderful, the pilot should still take care to not be too trigger happy, as the exceptional ballistics of the cannons will prevent the need to waste copious amounts of bullets on a single target, increasing the endurance of the aircraft in the hands of a patient pilot.

Unlike the usual Japanese low-altitude and highly manoeuvrable fighter aircraft, the Ki-87 is a high-altitude bomber interceptor with mediocre speed and climb rate but less impressive agility. Featuring something relatively new for a Japanese fighter, the Ki-87 has a notably visible turbo-supercharger to boost its high altitude performance at the cost of aircraft weight and size. As such, it cannot be played like most other aircraft from the Japanese tree, but rather as a reserved Boom-&-Zoom that can abuse its brutal acceleration in a dive to pick off unwary victims.

For engaging the enemy, The Ki-87 is best at boom-and-zoom tactics. '''Side climb''' to around 6,000 m and fly over enemy formations, once in position roll the plane to target, maintain coordinated control and correct rudder as at that altitude it is very easy to stall. Descend fast but not so much that the controls get sluggish. Once lined up and in range fire a short burst, the very heavy armament will rip the enemy plane apart; even evasive countermeasures will be insufficient for a properly executed Boom & Zoom.

Against heavily armed aircraft such as the B-17, B-24, and B-29, and other heavy bombers, climb at least 600 m above them use slashing boom and zoom tactic firing short bursts, once the bullets hit the target, fire longer busts then jump back up. Ideally you should aim for large critical parts such as the wings and tail plane. The cannons on the Ki-87 will make short work of essential components and being substantial offer best chance of hitting. Never attack behind and at nearly same speed as you become a perfect target for multiple weapons. The Ki-87's fuel tanks are somewhat easy to ignite, and you won't last long if they do.

* '''Force Headons''': The Ki-87 can't energy fight or turn fight with any props (Save ta-152 C-3 and P-47M). It will be outclassed. The only time you should ever turn fight is if the enemy is crippled or in a low energy state. To deal with fighters that are higher than you, you need to step up and force a head on. Most likely, allied players will take the head on. Your Guns good velocity should be enough to kill them. Remember to pull off early, as only one quick burst can kill you. If the enemy is higher than you and appears to engage, dive down. The enemy will most likely level out. Keep your speed high, as this will allow you to pull up and engage in vertical head ons. This is your last chance to score the kill, as the enemy will now be at an advantage.

Description

The majestic and hard to master Ki-87.

The Ki-87 is a premium rank IV Japanese fighter with a battle rating of 6.0 (AB/SB) and 5.7 (RB). It was introduced in Update 1.63 "Desert Hunters". Originally a pack vehicle, it was discontinued from the store after the 2018 Independence Day Sale, but was brought back for War Thunder's 7th Anniversary as a premium purchasable in-game for 6,090 Golden Eagles Ge icon.png.

The Ki-87 feels similar to a Japanese P-47. It has poor energy retention in very sharp turns, a lacklustre roll rate, and a sluggish feel. The Ki-87 has issues with overheating on WEP, and you'll need to use manual engine control to operate this plane at its best. However, all these flaws mean nothing to an experienced pilot, as the Ki-87 has the most fearsome armament of the super props. The cannons have excellent velocity, and usually one shot everything, and bombers fear you like the plague. The Ki-87 can reach amazing speeds in dives, and you can use tactics to force head-ons with many opponents.

The Ki-87's powerful armament consists of 2 x 20 mm cannons by the engine and 2 x 30 mms mounted in the wings.

The Ki-87 makes use of a turbo-supercharger, meaning that it won't suffocate as much at high altitudes, so you can keep your engagements high. Planes like the Yak-3, F4U Corsair, and Bf 109 will be outclassed by the Ki-87 because of their poor high altitude performance. It is important to note that the turbo supercharger is not controlled by manual engine controls, so you won't need to worry about adjusting your supercharger gear or turbocharger settings.

Using WEP, the Ki-87 is able to climb to just over 5,500 m in five minutes, a strong climb rate. Bombers spawn in at 3,000 m so you can quickly climb above for positional advantage for booming and zooming. If the Ki-87 retains momentum from the dive and engages the targets, it will be able to climb back up to the operational altitude it was before engaging the enemy. It is recommended to take the minimum load of fuel, set your guns targeting to 500 m and turn on vertical targeting. You should run the tracer belts for your 30 mm cannons and the universal belt for your 20 mms.

For landings, slow to at least 300 km/h (180 mph) before dropping the main gear and 250 km/h for flaps. Ideally, be about 50 m in altitude at the end of the runway and hold 200 km/h until touchdown.

The flight performance feels slow and sluggish, yet powerful. The turning and energy retention is not good either. This plane also has overheating issues. to solve performance issues, it's always best to go for a side climb, especially when in uptiers! The plane dives insanely well. The turbo supercharger will keep the plane's performance up while at altitudes above 5,000 metres.

The Ki-87 is armed with:

  • 2 x 30 mm Ho-155 cannons, wing-mounted (150 rpg = 300 total)
  • 2 x 20 mm Ho-5 cannons, wing-mounted (150 rpg = 300 total)

Japanese rank IV aircraft are typically armed with a respectable array of guns, and the Ki-87 is no exception. Although the 20 mm Ho-5's are nothing to write home about, the 30 mm cannons are some of the most feared, respected and deadly weapons in the entire game. When armed with the Tracer belt, the Japanese 30 mm cannons have a muzzle velocity that surpasses even the M2 and M3 Browning .50 cal HMG's at a staggering 920 m/s, and when combined with the high explosive filler and large calibre, these beasts will make short work of any aircraft that's unfortunate enough to end up in their crosshairs.

The usual issue with 30 mm cannons on WW2-era propeller planes - that being their lack of sufficient ammunition capacity - is notably absent on the Ki-87, which mounts 150 round per gun instead of the usual 60 seen on other aircraft like the Ki-84 hei and J7W1. Although this increased ammunition capacity is indeed wonderful, the pilot should still take care to not be too trigger happy, as the exceptional ballistics of the cannons will prevent the need to waste copious amounts of bullets on a single target, increasing the endurance of the aircraft in the hands of a patient pilot.

Usage in battles

Unlike the usual Japanese low-altitude and highly manoeuvrable fighter aircraft, the Ki-87 is a high-altitude bomber interceptor with mediocre speed and climb rate but less impressive agility. Featuring something relatively new for a Japanese fighter, the Ki-87 has a notably visible turbo-supercharger to boost its high altitude performance at the cost of aircraft weight and size. As such, it cannot be played like most other aircraft from the Japanese tree, but rather as a reserved Boom-&-Zoom that can abuse its brutal acceleration in a dive to pick off unwary victims.

For engaging the enemy, The Ki-87 is best at boom-and-zoom tactics. Side climb to around 6,000 m and fly over enemy formations, once in position roll the plane to target, maintain coordinated control and correct rudder as at that altitude it is very easy to stall. Descend fast but not so much that the controls get sluggish. Once lined up and in range fire a short burst, the very heavy armament will rip the enemy plane apart; even evasive countermeasures will be insufficient for a properly executed Boom & Zoom.

If no bombers are present, then you might have issues engaging enemy fighters. The Ki-87 can only do a 21 m/s climb at 17 degrees, which makes it vulnerable to being outclimbed by nearly everything. As such, you'll need to side climb and then engage from the side. Do not try to turn with anything.

Against heavily armed aircraft such as the B-17, B-24, and B-29, and other heavy bombers, climb at least 600 m above them use slashing boom and zoom tactic firing short bursts, once the bullets hit the target, fire longer busts then jump back up. Ideally you should aim for large critical parts such as the wings and tail plane. The cannons on the Ki-87 will make short work of essential components and being substantial offer best chance of hitting. Never attack behind and at nearly same speed as you become a perfect target for multiple weapons. The Ki-87's fuel tanks are somewhat easy to ignite, and you won't last long if they do.

Tactics to Win With

  • Force headons: The Ki-87 can't energy fight or turn fight with any props (save Ta 152 C-3 and P-47M-1-RE). It will be outclassed. The only time you should ever turn fight is if the enemy is crippled or in a low energy state. To deal with fighters that are higher than you, you need to step up and force a head-on. Most likely, Allied players will take the head-on. Your guns' good velocity should be enough to kill them. Remember to pull off early, as even a quick burst can kill you. If the enemy is higher than you and appears to engage, dive down. The enemy will most likely level out. Keep your speed high, as this will allow you to pull up and engage in vertical head-ons. This is your last chance to score the kill, as the enemy will now be at an advantage.
  • Keep your speed high: You need to worry about speed and altitude. DO NOT go for ground targets, as you will be an easy target for enemy fighters (a low and slow Ki-87 is as good as dead). Instead, keep your speed and altitude high, and have spatial awareness. Know where your enemy is.

You'll need to keep the prop pitch at 99-98 percent while in a climb, and adjust it to 90% when traveling above 700 km/h. The radiators should be kept at 100% while on WEP. The mixture should be adjusted at these levels:

  • Sea level: 100%
  • 1,000 metres: 90%
  • 2,000 metres: 80%
  • 4,000 metres: 60%
  • 6,000 metres: 45%

Pros and cons

Ki-87 over the Pacific.

Pros:

  • Excels in high-altitude bomber intercepting
  • Great gun velocity, you can engage bombers from over a kilometer away
  • Powerful armament consisting of 2 x 30 mm cannons and 2 x 20 mm cannons
  • No wing-mounted fuel tanks
  • 30 mm cannons have a huge amount of ammo
  • High red-line speed of 840 km/h
  • Fast at diving
  • Can equip bombs, although it will affect the aircraft's speed and turning time

Cons:

  • Not as manoeuvrable as other Japanese aircraft, feels very sluggish
  • Really bad energy retention, especially when coming out of a dive
  • Plane tends to wiggle in sharp turns, bleeding tremendous amounts of energy, so don't make too many sharp turns
  • Crew skills, if the crew skills are not high enough it is very easy to black out
  • Fuselage fuel-tank is susceptible to fire
  • Overheats extremely quickly, it's advisable to open the radiators using Manual Engine Controls
  • Mediocre climb rate
  • No interceptor spawn
  • 30 mm HEF-T has only a maximum penetration of 2 mm
  • Begins to lock up at around 700 km/h (435 mph)

History

Improved metallurgy and engineering in the 1930s saw a massive leap in aircraft performance, especially the once bulky, boxy, lumbering bombers reborn as sleek and sexy machines that left old fashioned wooden fighters in its vapour trail. It was not long before those flying rag fighters were also updated with gleaming aluminum and once again surpassed the bombers top speed. Yet bombers still had a trick up their sleeves, altitude.

Ki-87 at the cargo port

Flying above 9,000 m (29,500 ft) in super cold thin air and rarefied oxygen was both a technical and physiological challenge. The long wings and large interiors of bombers offered space needed for extreme high altitude flight, example the Ju 86P/R bomber which flew above 12,000 m (40,000 ft) with impunity over England, beyond the RAFs reach for months. The B-17 and B-24 could also operate at altitudes the Bf 109 and Fw 190 had difficulty reaching.

The Ki-87 from another angle in Cargo Port

Predicting the same for Japan, the military wisely ordered research into high altitude single engine fighters as early as 1942 and by 1943 work was underway on the future Nakajima Ki-87 and the alternate Tachikawa Ki-94. At 12,000 meters the air density is about 1/4 that of sea level necessitating a huge supercharged engine, but its internal "blower" needed an additional boost so a "turbo-supercharger" was added, powered by high velocity exhaust gas. This combination is exactly like the P-47 Thunderbolt has, except this time the turbo was mounted on the right side of nose on the prototypes and not in rear fuselage. High aspect-ratio wings were chosen for the thin air (compare Fw 190 with Ta 152), but with limited space to mount the dual pair of 30 mm and 20 mm cannons in an unusual step Nakajima chose a landing gear retraction like on P-40 Kittyhawk. High altitude flight is also extremely uncomfortable for the pilot so the cockpit was partially pressurized and extra tanks of oxygen installed. Pilot armour, thick bulletproof glass, self-sealing fuel tanks, and hard point for bombs were also added. Finally enough fuel for at least 2 hours flight resulted in a massive aircraft for the Japanese, well over twice the weight of the A6M2 Zero.

It was an enormous technical challenge for Japanese industry taking a long time to overcome teething issues. Japanese aircraft rarely utilized turbo-superchargers in their planes, so experience in operation was limited, and although the 90° retracting gear was a favourite design, it took Nakajima months to get it to operate correctly.

The prototype flew for the first time in April 1945 at a time when the anticipated B-29 bomber was pounding Japan, but by then it was too late. Disruption by bombing and dwindling resources prevented the second prototype from flying and attrition of what little fighter defence Japan had. Ironically, with such weak home defence, the B-29's flew much lower so they could bomb more accurately, negating the purpose of the high altitude Ki-87!
