How do you know that the next planes wouldn't fall behind for a good 30-40 km/h? That was pretty ususal, as designers very often overestimated those numbers.Д«ut won't change anything important of the matter. How do you know that your next paper plane wouldn't be the next one with an unsuccesful history?В Again, you would never know. I don't know why are you trying to convince me how usual was that. The Fw 190 was just another example, how the paper design could be different from the final plane that was succesful in the war. I don't mind well documented prototypes (preferably as premiums), but the Ki-88 or the J6K are not one of those. I didn't say differences in prototype to production, I said differences in blueprint (paper) design to prototype/production, as even prototypes could have different stages. So I can't see how these would be your breaking point, when such planes have always been implemented. Mind you, WT adds prototype planesВ in ideal function, which have little to no real useful flight data, relatively often. I don't see how differences in prototype to production matter here, that is the progression of design after the fact, and prototypes are added to WT frequently. My point is that more often than not, planes were not dramatically different than the estimated flight performance. There being many of these isolated incidents does not mean it was the norm.

A plane falling apart in flight was highly unusual. J5N falling far below the requested performance was unusual. But it is still uncommon that such planes areВ called paper. So, the fact of the matter is: you would never know with paper planes.ДЄs I said, anyone recognizes that unflown planes have no flight data, so this point is moot. These are even bigger differences than the case of J5N.Д«ut even with well known planes like the Fw 190s, the first succesful prototype or first production variant were different from the final plans.

There were even cases when the first flown planes fell apart in the air because construction faulires and the projects were abandoned. Misjudged performance was pretty common in WW2. You can argue how should we call these planes, but they are not differ from the planes existing on papers only at all. The Ki-88 might be partially built, but parctically it is a paper plane. Planes are a different breed, so a partially built model means exactly nothing regarding the performance and anything important. Will navy branches include projects that were never realized in metal, but existed only in blueprints, not to mention those that never got past the stocks?ДЄ: Yes, weвЂ™re not ruling that out, especially with regard to projects that were completely ready, but whose construction was never finished for one reason or another. ThatвЂ™s why everything is calculated in advance, and in truth, a ship is born long before it reaches the shipyard, itвЂ™s born in the final construction blueprints. Q: Designing a ship (not a boat) is a very serious matter, it cannot be seriously redesigned if mistakes come up when itвЂ™s already been built. The fact of the matter is, planes that were built but never flew are added to War Thunder all the time, and if you would leave for such planes being added, you should have many times over, even recently. Obviously planned performance is never perfectly aligned with reality, but such a major difference as J5N was a rarity. This plane was just before final assembly when canceled. So playing some kind of 'what if' game with planes is nonsense. There is a reason why they needed so much test flight and evaluations, revisions and in some cases complete redesign. Paper and never tested planes are not like tanks and ships. Despite the other five prototypes also having flown with numerous enhancements, the aircraft never achieved its design speed, and the project was abandoned soon after in February 1945.'ДЄnd that's why we don't like planes that never flew. J5N: ' The top speed attained was only 597В km/h (371В mph) вЂ“ far below the specified 666В km/h (414В mph) of the requirement. compare the P-51H estimates and real numbers), that's a fact. And estimates were way off in WW2 at every nation, even late war (e.g.
