The Clone Aircraft Corporation has begun testing a hybrid engine in a retired K40 fighter. The engine is bi-mode, able to be used as a normal turbine but also with an electrically powered fan for low but high efficiency thrust. The test K40 will test cruising in "electric mode", the K40 has a number of fuel cells fitted though also can generate electric from the other engine in turbine mode to power the other.
The CAF has no plans as yet to field this kind of engine in one of their fighters (though a similar engine is used in the K3 trainer and K58 COIN aircraft). However it is rumoured the technology may be included in a future version or upgrade of the K45.
