Almost certainly would help WS-15 production set up. Which is why I said 5 years instead of the 10 years it took to take the industry go from WS-10A serial production in very limited numbers to current WS-10B and WS-10C batch production in current impressive numbers (relative to past but not impressive by US production rate for F110 in the past and F135 now).

I think it’s very unlikely that you see only a 50% reduction in overall production ramp time for the WS-15. Entire bodies of process knowledge and production systems didn’t exist for the WS-10 that now exist for every new engine going forth. The 5-10 years for the WS-10’s production to ramp up was as much about building the general infrastructure and production knowledge to do advanced turbofan production. If you take 10 years to learn C++ from not knowing *any* programming language and then try to learn Java your speed of learning isn’t going to be reduced just by half.

Vortices, formation flying, and full afterburners that stand out beautifully thanks to the overcast.
