3-4 years for Hurjet... we don't even have an engine for it. It will take us at least 5 years to build an engine. Or we could buy a FOREIGN engine. But then and again who can trust Western countries anyway? They'll probably embargo us again.
The engines are British for Hurjet as far as I know, they are not from germany,france or the US which are known to embargoe us. Brits wont cause us troubles I believe.
