Karnak, I was not referring to use Fw200 as a bomber, so, the payload is secondary, speed may also be secondary having a radar.
The idea is to use these Fw200 to discover enemy CV groups at long distances, even to coordinate and control "future" submarine groups. Check the link above.
Ju188 had also the same radar, but it had much more limited range than Fw200. In fact, Fw200C almost doubled the B17 range.
As a "plus", some Fw200 were armed with two guided missiles or two guided bombs, and were able to transport supplies and troops (big goons?).
