United states aerospace giant General Aviation has successfully tested a prototype of next generation turbo-fan engine for combat aircraft. The engine named GE XA100 is claimed to have an increase thrust of 10% and an improve fuel efficiency of 25%. This will in turn increase the range of a fighter jet by 35%.
