Germany did not convey, its the company who did? Issue would have come had the German Govt denied export license. But this is a company's decision. The powerpack related work which is probably handled by CVRDE, terms had the 1400hp MTU engines related work alongside in the schedule for assistance in the 1500hp powerpack development work. I guess priority is now shifting. below estimate in the job ad from December 2023.
I would have shelved the MTU engines plan myself, but perhaps there are certain issues, like need to redesign some LRU or similar major/minor niggles.
