You mean the GE/RR F136... which is the "back-up" engine for the F-35?
A US company (GE) is losing out on this as well.
Note that GE has the majority share on this engine... but it is a couple of years behind the primary engine for the aircraft (P&W's F135), and would still take a considerable sum of money to complete for service.
That is just how it is when a government has way overspent itself... unnecessary things, like a second engine design for an aircraft where the primary engine is meeting all requirements and has basically completed all development, tend to get chopped in the process of cutting back on wasteful spending.
