That's not right masher. First off only a couple were modified (note the extra foot or so on the tail wheel?), and none of them were A8 models if I recall. I only recall a few testbeds on A-5s or equivelant F3 models. Also note the pictures show an A5 model (or F3, the line really was kind of blurred as to what was an F3 and what was an A5 with modifications), with the small-caliber MG cowling, the inboard pitot tube, etc.
There were some F8s that carried big bombs, and I think that's what KG200 was formed for.
One source that seems fairly good says:
"The "FW-190A-5/U14" and "FW-190A-5/U15" were both torpedo-bombers with an extended tailwheel to give ground clearance for the torpedo.
There was a similar modification, the "FW-190F-8/R15", for carriage of an odd munition known as the "BT-1400 torpedo bomb". The BT-1400 weighed 1,400 kilograms (3,090 pounds), and looked much more like a bomb than a torpedo, with a long tapered nose, three tailfins (including a folding bottom fin to permit ground clearance), and no propeller.
It is unclear if these FW-190 modifications saw much service, though it appears that late in the war the Luftwaffe special-operations group, KG-200, used FW-190s carrying BTs in operations against the Soviets. There are also stories of such long-tailwheel aircraft carrying SC-1800 1,800 kilogram (3,970 pound) bombs, if with great difficulty and stripped of everything that could be removed. They were apparently used to try to destroy the Remagen bridge over the Rhine, seized by the Allies in early 1945, but with no success."
Note those carried bombs, despite the name having the word "torpedo" in the name of the bomb.
