P&W fights US government criticisms of F-35 engine reliability - 4/30/2015 - Flight Global
Interesting to see the VTOL engine is almost twice as reliable as the CTOL engine. Counter intuitive. I wonder why that is.
The drop off after F136 cancellation is interesting. I assume there is more to this though, were there also cost/weight/production changes that explain the drop off? I suspect "Engines" would know.
