Umbau mods and Rüstsatz kits
This chapter gives details of the basic characteristics of the 10 Fw 190A types manufactured but for each type there were alternative versions produced, usually in small numbers or as one-offs, at the factory.these were indicated by a ‘U’ number, such as Fw 190A-8/U1. Some only existed as proposals. In addition, most of the Fw 190A types were supported with Rüstsatz conversion kits that could be fitted in the field. When added to a standard aircraft, altering its characteristics, they were referred to in the type’s designation using an ‘R’ number, such as Fw 190A-4/R6. Here are all the Fw 190A Umbau modifications and Rüstsatz kits. Where a number is missing, e.g. Fw 190A-4/R3, either that designation was never allocated or it is simply unknown to what it may have referred.
