I think the Ta-152C-5 was suppose to be armed with five MG 151/20mm. It was later changed to a engine mounted MK 103 and one MK 108 in each wing instead of the 20mm.
What I don't understand, this was to be named the TA 152 B-5? I'm guessing this is a mistake as a the correct would be TA 152 C-5.
The last version drawn up was the Ta 152C-1/R14 which was to be a torpedo bomber. Interestingly the RLM asked for a torpedo bomber in December 12th 1944, what's interesting is the FW-190 was also chosen to carry the torpedo. Kurt Tank designed both aircraft, Tank was going to build both the FW 190 F16/R-14 and the TA 152 C-1/R14 at the same time so he could test both, one of the issues was the directional stability of the massive torpedo.
Unfortunately he was planning on doing the mockup and test in March 1945, to late to be made, one thing that hindered the build of the ta-152 is the production did not start on the Ta 152C yet, also the factories being bombed destroyed his only mockup. I have the photo of the TA152C with DB603 LA, so I know the aircraft was built, unfortunately it was to late in the war.
Would of been interesting to see how it flew, I always knew there was a FW190 prototype for carrying a Torpedo, I had no clue Tank wanted both built to test them both.
