Weird to think that the near 50 year old Hornet design is in many ways still more capable than the F-35.
Aircraft 'ages' are interesting:
Production F-18 Super Hornets first flew around 1995 (31 years ago).
Production F-18 Hornets first flew around 1980 (46 years ago).
The YF-17 first flew in 1974 (52 years ago).
Heck, the F-5 Tiger (I count it as the father of the hornet) first flew around 1959 (67 years ago).
Yeah, that's a plane with a VERY long design legacy, but you can track major updates to the design every 15 years or so.
By contrast, the F-35 first flew around 2006 (20 years ago). Its only 11 years 'younger' than the Super Hornet, but a new design.
If the F-35 had a similar history to the Hornet family, we should have seen an evolved design emerge in the past five years. I know there's the 'blocks' but that's not really the same thing.
Also interesting: The first RAAF F-18F Super Hornet flew in 2009, and the first RAAF F-35 was completed in 2014, so our F-35s are only about 5 to 8 or so years younger.
We could/should see the entire RAAF combat force being retired around 2040-2045. Gonna be an EXPENSIVE decade...
But could there be a 'Super Lightning II' by then? Seems unlikely.
Not sure where I was going with this - it's just interesting that we think of one design as 'old' and the other 'new', when in fact the they're not that far apart in some ways...
