Was the B-29 rushed into combat?

Was the B-29 rushed into service, causing its heavy mechanical losses?

The replies disagree over the word 'rushed', but agree that the B-29 attempted a difficult technological leap while moving rapidly into mass production and service.

Whether the B-29 was rushed is disputed here. One interpretation emphasizes the difficulty of taking a complicated new aircraft from test examples into mass production and widespread service, while accepting that more development time would have helped. The later B-50 illustrates how much the design family improved after its early problems, including chronic engine fires, had been addressed. A competing interpretation calls the B-29 rushed because its electronics and other systems pushed beyond what could readily be developed and introduced at the time. The step beyond the B-24 is estimated at roughly one and a half generations overall, with some components advancing further than others.
