Generation 4.5 means it has similar performance and stealthiness compared to the F-18 and F-16 but slightly more refined design and better avionics. The Rafael is also considered 4.5. The lastest upgrades to the F-15 and F-16 could probably also be considered 4.5
Thank you for your informative reply.
