Did they have a turboprop big enough though already though for the 400? (SHP?)
M.54 I reckon would take a hell of a lot of poke without new, modern engines.
Add to that the problems with older fuel burn and the effect hence on mission payload.
Just a few ideas why they stuck with creating new donks.
