The TF-40 two-seat trainer version of the F-40 fighter fleet is now showing it's age and the HCSAF did consider buying a two-seater version of the F-45. However instead it has been found to be cheaper and quicker to rebuild the TF-40s instead. CAC is now working on a TF-40M rebuild which will have a totally new avionics suite to aid training for the forthcoming F-45C/K. New engines and an airframe refurbishment to give the type 15-20 years more service.
One TF-40 will be rebuilt over the next few months and if the trials next year are successful then the 155 other TF-40s will follow suit.
