Hi Basil,
It is worth mentioning that the P 203 was not intended as a bomber aircraft but as (according to the original Blohm & Voss brochure) a "Zerstoerer" (heavy fighter / bomber destroyer), "Schnellkaempfer" (attack aircraft) and Nachtjaeger (night fighter).
Well, "Schnellkämpfer" is short for "Schnellkampfflugzeug", or "fast bomber", so I'd not say it was not intended as a bomber
An attack aircraft would be described as "Schlachtflugzeug" or "Schlächter", or maybe as "Erdkampfflugzeug" (though I'm not sure off the top of my hat whether the last one really is a WW2 term).
But Vogt's intention really was economical production, and having a multi-purpose type of course helped with that, so that's really a very minor point I'm raising.
Regards,
Henning (HoHun)
