That is not a pivot I would have expected. Aviation turbines are not good utility turbines. If you just need to beef up your turbine engineering, drone turbines are probably the place to go. Less competition from GE etc.
It's a VC fundraising oriented pivot I think.
I don't think they expected it either, but it's building expertise in that general area, the question is if that expertise will transfer back over to supersonic jet engines, or if they're different enough that they can't.
