4-engined bomber for 1943-44

[davparlr]

You mean like the B-33A only with turboed R-2800s instead of R-2600s?

Yes, only I would have cancelled the B-26 whose role could easily been taken over by the B-25, and the B-17 or B-24, either of which could adequately do the job of the other. The B-24 would probably be preferable to keep. So, the total quantity of engines and aircraft would not change. Of course I am looking at the war in excellent hindsight.

An (mostly) unarmed bomber that would be a Mossie/Mixmaster combo: the 2 engines on wings, other 2 engines in upper part of the hull, behind the wing (Mixmaster's were in front of the wing) driving 2 props at tail. Some guns in front, maybe also in the nacelle, looking aft & remotely controlled; the night bomber maybe without any whatsoever.

I believe this is incorrect. Wagner's American Combat Planes shows the B-29 as having a range of 3250 mile/20,000 lbs. bombs which is identical to the National Museum of the US Air Force.

sorry i used Joe Baugher page as source and again this go wrong

from the link posted in (recent) B-29 thread at 140000 lbs with 20000 lbs bombs and 39396 lbs fuel B-29 has 2627 nautical miles range (around 3023 statute miles)

so back to topic 2/3 of range with 1/2 of bomb load

it's a reduced B-29 it's possible i'm not more sceptical in the technically capability
but i've doubt in the timeline the B-33 not got the prototype at november 25th 1942 it's hard to think they can go in production in '43 also w/o B-26 work almost starting in '40 i don't know if starting in '39 we can project a similar plane

Other aircraft timelines

B-24

Concept begun Sep. '38
B-24 prototype ordered Jan. '39
1st production Dec. '40
1st B-24A delivery May,'41

B-29
Prototype ordered '40
1st production delivery Sep '43

The upgraded B-26 would have similar technology to the B-24 but bigger and larger engines but not near the complexity of the B-29. I don't see a problem in delivering start of '43 if design starts in '39 or first of '40.

if was so easy because the not get prototype of B-33 after 2 years?

[davparlr]

We actually know very little about the program including funding, which may have been on the back burner due to the B-29 program, or development issues. However, it doesn't seem outlandishly long, certainly not enough to indicate a problem.

June '41 prototype contracted
October '41 mockup approved
Nov '42 programmed cancelled

So only a year and a half from contract to cancel and only 12 months from mockup approval to cancel. Remember, this aircraft just went from two engines to four different engines. It also should be noted that Martin went on contract for production in January, '42, for some 400 aircraft, another indication that there appeared no significant problems at that stage. I don't think this supports your argument. I would have started this project earlier, around the end of '39.

june '41 was 4 engined prototype contracted, the twin engined was already contracted and so in june they not start o to nothing

we have already did this discussion and we don't agree so i think we can agree that we are in disagree.
