Design and development

Development of the WS-15 afterburning turbofan engine began in the early 1990s.[1] .[3] The thrust target was reported as 180 kilonewtons (40,000 lbf) in 2012.[4]The new engine is speculated to incorporate two-plane thrust vectoring nozzles.

gollark: I'm not sure, but it SEEMS that way.
gollark: Yes, but it doesn't seem to be fast enough?
gollark: * then
gollark: I'll definitely have to look at transfer node mining them.
gollark: Hmm, 1 billion, that's quite a lot.
