Keep in mind that the Ju 188 was actually nothing more than a Ju 88 with a redesigned, streamlined cocpit section. Hence why the first variant was an Ju 188E. Originally it was designated Ju 88E (D being the last variant), it was just redesignated later. In short, it was not a seperate development, just a newer version of the Ju 88 with more powerful engines, and improved performance!
