HELP, Jap aircraft

Post by herbieh »

OK, Ive been fiddling around with the UV editor trying to sort out how japanese planes perform.
Now we all know what a zero is, can do, cant do
same with betties, nells, and maybe sallies

But come 1943 and later and there is a bewildering selection of planes, tonies,georges?, Ki43,Ki 44 ect, ect, ect
Let alone all the bombers.

Now the question for yuo gonards
Ive got to decide production piorities.
Could some one care to list in a very simple order Japanese planes that are "best" for 43, 44, or 45, and maybe ones that are a total waste of time.

Ive been trying various fighters against B17s, and one sort seems to go OK, but then try it against hellcats and Yikes!
(This is a test with very experienced pilots)
Did all that make sense?
I want to get rid of oscars asap, what should I build after the zeke?

Personally after 43 I wont be concentrating on carrier air, just the heaviest land fighter the japanese has, which is?
Thanks in advance.

Won't comment on the overall question..., but the answer to the above is easy. To shoot
down heavy bombers, you need maximum firepower and a stable gun platform. To deal
with the Hellcats you need speed and manueverability (and hopefully a hight advantage).
One set of qualities is rarely compatible with the other. A twin-engined "heavy" fighter
might be ideal for dealing with B-17's, but is dog meat when dogfighting a Hellcat.

Briefly, the Oscar (Ki-43) first model only had two 7.7mm MGs. Very good dogfighter, but very light and too slow overall. The Ki-43 IIIb upgunned to two 20mm cannon.

It was replaced with Ki-44 and Ki-61. The Ki-44 was originally planned as an interceptor, although it couldn't keep up with the Ki-45 in practice. I think the Ki-61 might be a better choice in game terms. While it suffered many engine and production difficulties, it was both fast and maneuverable. Used a lot in home defence.

The Ki-45 is a twin-engine heavy fighter/bomber/nightfighter suitable for attacking unescorted bombers.

Another good bet would be to build the Ki-84 as soon as practicable. It is a very good land-based A/C. After service trials . these showed up in Apr '44 to the end of war.

But you can't replace Zekes with any of these, because they can't operate from your carriers. I don't think there is a historical replacement for the A6M.

The Ki-84 "Frank" was generally regarded as the best Japanese fighter of the war. It was deployed operationally in the Summer of '44.

The following is a very general aproach to explaing these planes, this is not a flight sim so I will not expound, and UV and WiTP handel these planes in a very abstract maner, and many of the plane types are generic in the game, also in UV they have the Ki-84C which never realy produced in any number (it has the 30mm Cannons).

Tony (Ki-61), Early models went into action in New Gunie, whear it proved a very formadable aponet for the Allies, superiour to al but the P38 in most respects, early Models had the MG 151, but later ones switched to the better Japanese Ho-5 20mm Cannon, no mater the time of war the Ki-61 is a good machine, though Early models were the best preforming generaly, specificaly in terms of climb rate. They even I beleave out climbed the Ki-44 at least the early models did.

Ki-44, Another good Army fighter, though not as well rounded as the Tony, the Tony handeled better, it's 40 mm cannon was useless (the modles that had it). Generaly speaking a good climber, but by the time the Ki-84 was coming in to service the Frank was defenatly the better machine.

Ki-84, Superlative aircraft, as noted above likely the Best of the Japanese Army Machines, it was a good designe, post war tests under ideal condations with US fuel produced some stagering results, it out preformed a P51D, and a P47N ( prety shure it was a N).

Ki-45, Ground atack and Bomber intercept, good PT Boat killer as well.

.....................


Jack/George - Navy land based interceptor, offered good climb rates and Good forepower, two 20 Type 99MK I and two 20 MM Type 99 MK II cannon, production delays slowed it introduction to the front and by the time they were largely iroedout the George was intering service, the N1K1 (George) was the Better machine by far, initialy Georges suffered a number of Mechanical bugs, and the Mid wing N1K1 was part of the problem that and it's long landing gear, these probles and others were ironed out and the result was the N1K2 preformance wise almost identical to the N1K1, it was an excelent fighter, the best the Navy had during the late war, it had the same engine as the Ki-84 though it was a bit slower. The George also incourperated a noval automated flap system which gave it superlative handeling qualitys.

Another point to remember is that Japanese Designers proved capable of designing
better aircraft than Japanese Industry was able to produce in any numbers. The Tony
sufferred a lot of trouble because of failings with it's liquid-cooled engine (unique among
Japanese aircraft); and all of the later high performance types suffered from industry's
inability to meet high-end specs in production runs. This was a basic failing of Japanese
Industry which was only made worse by bombing and shortage of skilled workers.

Under perfect conditions, and with perfect maintainence and construction, and the availability of high-octane AvGas, some of the last Japanese aircraft were as good as anything flying in theory..., but rarely in practice. But if a "good" one happened to get
into the hands of a superb "veteran" flyer, then some US pilots got a rude shock for a
while until the maintainence caught up to it.

The Ki-84 proving "superior to" the P51-D and P47-D (not N) in post-war tests is an oft-repeated but incorrect rumour. Using US 100 Octane fuel the Ki-84 proved capable of a maximum speed of 427 mph at 20,000 feet, using war emergency power. This speed exceeded that of the P-51D Mustand and the P-47D at that altitude by 2 mph and 22 mph respectively. The P-51D and P-47D retained the edge in roll rate, and at speeds in excess of 300 mph, the P-51 and P-47 could out-turn it. Both aircraft could outdive the Ki-84. Both aircraft had superior armor to the Ki-84 and were more generally survivable in the face of damage. The Ki-84 was a superior climber, but only up to 20,000 feet (as it should have been, it only weight 7900 pounds). In addition, the Ki-84 had several operational problems -- an unreliable engine and structurally weak landing gear. It also had poor taxi and ground handling qualities, and pressure had to be maintained on the starboard rudder pedal to counteract a tendency to swing to port caused by the high engine torque.

In operational use by the Japanese, a Ki-84 in mint condition could obtain maximum speeds of 390 mph, making it superior overall (when operating properly) to the USN F6-F, but not to the F-4U or the P-51 or P-47.

Note, at higher elevations the Ki-84s performance dropped off radically, giving both the P-51 and the P-47 a speed edge, even assuming an "American rebuilt Ki-84 fueld by American avgas."

Man that was helpful, the linked sight was amazing

Ok, replace oscars with tonys, tonys with franks, and zekes with the george, and build nicks galore
replace all bombers with P1y Frances

Got it[:D][:D]

The Frances is defenatly a good Bomber but so is the Peggy, These would be the best choices for Late war Navy and Army Bombers respectively, the later has a much better defensive aramement as well. The Navy did BTW use the Peggy as well (Not shure if UV or WiTP represents this).

................

pauk: The 40MM Cannon the Ki-44 mounted was a very odd weapon, it was more like an mortar with an auto fead, the practicle range was sucidealy short, and the weapn was extreamly slopy in operation and in terms of it's balistics, I recal mention of 100 yards or closer to inshure some chance of a hit. Ho-301 Japan 40mm caseless 475 rpm 245 m/s , very low MV.

Note the 40mm Projectile drawing, the amoo is caseless, the propelent is contained in the base of the projectile:

..............................................

Historicaly as noted above prety much all the Allied late war fighters were faster and preformed better at alt than their Japanese counter parts, notable exceptions would be the Hellcat and the FM-2 . Many Allied late war fighters also possed superiour exceleration which depending on altitude could alow them to excape if they got into trouble. Allied fighters also tended later in the war to almost always fly to thier strengths, rarely mixing it up, prety much all planes like the F4U's and P47's could do with the Japanese is Go fast hit and run, they were total dogs in most other respects, but this was enough, this and the huge numerical advantage the allies had, and the handicaps the Japanese had in reliabality issues with some of their machines later in the war as mentioned above.

Interestinly as noted above Well maintained and well flow Georges could do a good job, Air Groupe 343, CAPT. Minoru Genda, formed this unit and brought in hand picked experanced units from all over the navy to fill it. of the 170 some odd piolets in the unit 35 were Class "A" piolets (figure given for just before operations over Okinawa). During operations over Okinawa the groupe managed the los of 29 aircraft for 106 kills, and 165 aircraft sortied.
During a 2nd of June battle over Kagoshima bay a groupe of F4U were caught in a bad position and 21 N1K2's atacked 23 F4U's and 18 of them were shot down.

You mean that they were "total dogs in all other respects except for armament, armor, and maneuverability at speeds in excess of 300 mph, in which categories they were consistently superior to the late war Japanese a/c."

Aramement, they could of course cary considerably haever Bombloads, but their gun packages were not any better, if anything the weapons on the Japanese planes were more efficient in many respects and at least as efficient in others, I am refering to late war gun packages hear.

Armor, Some late war Japanese aircraft did cary armor suficient to be effective aganst the 50cal. Allied Aircraft Armor was effective to a point, Japanese aircraft weapons did not relay on penatraion effects like US ordance did to acheave a kill, their reliance on HEI ordance primarly which focused on defeating the Airframe, not killing the engine or piolet, ect rendered the armor aspect a mute point to a degree.

High Spead Manuaverabality: This is in keeping with the above mentioned premise that the Allies prety much had one trick, go fast and stay fast, dont mix it up. I call the F4U and the P47 dogs based on what I have read about them, and to an extent my own personal experance flying them in sim's, they are largely extreamly unpleanst beasts with little redeaming qualitys, certainly the F4U is, the P47 is not quiet as bad. It is interesting that in Sims these planes suffer horably aganst Japanese planes like the N1K2, but in these aritifical areanas the Allied planes are seldom ever used as they should be, that being to their strengths, hince their one trick, go fast stay fast and dont fight, but Boom and Zoom, this is what they did in real life and it helped them win the war, once you get out of this limited aspect of the preformance window they are indead dog's.

I think there is no possibility that we will ever agree. The "don't mix it up" premise is a false statement. Typically pilots were admonished not to allow their airspeed to drop below a certain level. If, for example, a P-51 "mixed it up" with a Ki-84 but kept IAS above 350 mph, he could count on flying a more maneuevrable ship.

Your comment basically amounts to the assertion that US planes would be lousy at low speed dogfighting. So what? They'd be lousy at jousting too. Ju-jitsu would likely be difficult from a cockpit. Swordfighting is right out. No one now dogfights at low speed. The whole evolution of fighter/interceptor design has been towards greater speed because speed usually wins. The Allied designs were built for the qualities that win, not the qualities that do not matter. Like Frag said, who cares about the coffee maker?

As to the 20-30mm armament; US a/c routinely survived detonating hits from 30mm. Even the lowly wildcat. The airframe was too tough to take down with a single hit unless you hit a critical component. Given the low velocity and poor trajectories of Japanese aircraft cannons, the he-armed guns were a bad choice (unless you want to bring down a bomber). Against Allied fighters they'd have been much better off with 12.7mm. In contrast, the US 12.5 had the energy to rip the wing off most Japanese fighters if the gas tanks were full (12,000 foot pounds will do that), even if the bullet did not penetrate the target. So you are mistaken in assuming that the .50cal's effects were primarily from "penetration." Their effects were primarily from energy transfer. Japanese aircraft, with very few exceptions, did not have the durability to sustain hits from .50cal. I'll grant that some, like the Emily and Mavis were tough nuts.
