According to Official Guinness Records,

The most powerful fighter jet engine is the US aircraft engine manufacturer, Pratt and Whitney's engine for the F-35 Lighting II Joint Strike Fighter (JSF). Whilst its published power is rated at 28,800 lb thrust (128.1 kN) in intermediate power and 43,010 lb thrust (191.3 kN) in maximum power, on 18 September 2006, it set a record for thrust from a fighter engine reaching more than 40,000 lb thrust (178 kN).
NB, it is normal to quote engine power in lb thrust (hence metric in brackets).
