I don't think I said the 90 was an improvement on the 89, except as a transport thanks to the loading ramp.
No, but you did claim the new wing as a positive, and as we have seen, it wasnt.
Without knowing the layout of the equipment in the fuselage we cannot say for sure. The Ju88 was a pretty radical design at the time it was started for the German aviation industry.
How weird would it be if two bombers, designed side by side by the same company, ended up with the FAR LARGER bomber having a smaller bomb bay... and one incapable of being expanded at that...
Relatively simple, but as part of the overall changes needed at that point it would require just as much work if not even a bit less to just design a new, more modern aircraft.
No, quite simple, you dont even need to modify the fuselage structure as in other bombers, mostly just change aluminum by glass.
It will change the weight and weight distribution. Plus IIRC even the airliner versions adapted the fuselage to add the read load ramp.
The wing is a pretty substantial drag factor.
Not drag, not speed, the ramp was added on the V6.
B-29. Lancaster and He177 with a light load. Even the Ju288 was supposed to be able to with a lighter payload.
Nope, the He 177 did not have the 5.000Km range needed to make the trip, at best managed 4.400Km with 1t bombs as per its data sheet.
No Ju 288 ever reached even 4.000Km, not with Jumo 222s nor with DB 610s.
And, finally, how do you find a target 2.500Km inside enemy territory at night? A 5.000Km daytime trip would be a bloodbath for ANY bomber.
But you need better speed to survive night fighters. It would also help with making it harder for day fighters to intercept at altitude too. With 1.6 tons of bombs and who knows how much armor and defensive guns though, they were better off with the much cheaper He111s and Ju88s.
Better payload, acceptable defensive fire, faster, and much cheaper (at least 1 for every one Ju89).
How if they had B17-like performance of the 1942/43 variety in 1940 that would be a different story, as their ability to survive to target in the day would be much higher than the twin engine bombers due to the lack of British fighter cannons.
It cruised as fast as the Lancaster and B17, of course, we cant know that for certain until fully armed and with production engines.
The He 111 was limited to SC250s internal, the Ju 88 SC50s... it wouldnt be hard to put much more lethal 8xSC500s on an aircraft as large as the Ju89 and end up with a better range and offensive payload than the 3xHe 111 that Kesselring claimed could be built for 2xJu 89s. Less crew as well.
With proper turrets after 3 years of development they could have them with 2xMG FF, belt fed, or with 2xMG17Zs, some real firepower.
Again sure, but not as much as could be had with a fresh design like the He177, especially if it required 4 years of development to get it in production...which means in 1940 when it would be too late to really matter in the west, but still potentially useful in the East, just not as much as the Bomber A design. Really the big problem was the lack of a non-dive capable, four engine He177. A 35% increase over the 1936 Ju89 prototype isn't really worth it.

"Bird on hand" and so on...
Oh, development began in 1935, first flight 1936, service 1939 at the latest since it had no problems during early testing. Just like the Ju 88 until someone decided to screw it up.
Except the gondola was not outside the slipstream. It added weight the frame could not handle and increased drag. Of course they didn't really have an option considering the aircraft wasn't a bomber to begin with and was shoehorned into that role.
Of course not, and I never said that!!!
They needed the gondola for defensive weapons and the inside for fuel, so they put the bombs in the gondola as the simplest solution, big deal.
Responsive, stable handling and good stall characteristics are important for every aircraft. The point of sharing the calculation wasn't to make a multi-engine aircraft that was maneuverable like a single engine, but the impact of weight and drag on the ability to maneuver, which impacts even the safe handling abilities of multi-engine aircraft for things like take off and landing, as well as stalling.
Great, so do you have a source for such problems? The new engines would provide enough power so it would no longer be underpowered.
The Ju290 was a very different aircraft than the 89, with a different role, so talking about the wings as if it was a simple upgrade is really missing a number of other factors.
Which is why I pointed out those wings appeared on the Ju90 and didnt help at all.
The Ju89 probably needed more than just wing clipping, probably more a total redesign, which IIRC can change the tail as well to keep things in balance.
That is a whole lot of probablys there...
The reason that Walter Wever thought 1941 wasn't an issue was Hitler told him not to worry about a war before 1942. In hindsight you'd need a functional heavy bomber in production as of 1938 to have enough to be an improvement over 1940. Even 1939 is probably not enough time to build a strategic bomber force usable in time to improve on the force composition in 1940. Honestly Germany would probably be better served getting the Ju88 in service sooner by not adding the dive bombing requirement and ventral gondola, so they could phase out the Do17s in time for France, while also having enough time to work out the bugs from the first models. Because if you are going to build up a strategic bomber force it is going to come at the expense of smaller bomber production, while lacking some of the flexibility of the smaller bombers in terms of role. That could be somewhat mitigated if they had the fighter-bomber version of the Bf110 in service as of May 1940, but they wouldn't necessarily have the numbers to fully offset the loss of bombers in general, especially given that the Do17 used engines that were probably not suitable for strategic bombers or even the Bf110 (which was already somewhat underpowered with the 1940 DB601 engines as a fighter).
Ah! The Hitler defense, Hitler had no control over when wars began, and any professional soldier, from any country, in any period of history, trusting such statements, from anyone, is either an idiot or lying...
...other people might declare war on you, specially if you are doing stuff you are not supposed to do... like bombers...
First successful trial on blind bombing aids was in 1935, 200 Ju89s might make a difference in 1940 with proper signals security and no enemy night fighters.
Question, what is a medium bomber good for?
Had they opted for a less well performing tactical/light bomber to replace the Do17 they could have used the same engines:
https://en.wikipedia.org/wiki/Henschel_Hs_124
IIRC they couldn't because of the foreign exchange crisis due to rearmament. They were going to license a US aircraft engine in 1935, but the cost convinced them not to. In the case of transport aircraft they had already a large stock of the older, cheaper Ju52, which were just cheaper to make. In the end the vastly better Ju252 was just too expensive to make, as it required bomber engines and too many other strategic materials needed for combat aircraft.
Just make a transport version of the Ju 89... wait!
