Good Tribute, however only the US Navy legacy hornets are retired.
Australia are definitely still flying their "Classics", I was at the 77SQN mission brief for Dawn Strike on the 31st of May. However, they're not technically A's/B's anymore. With the HUG program and recent avionics upgrades they're now basically the A++.
The RAAF just completed it's Air Warfare Instructors Course (AWIC), which was the last recognised course on the Classic Hornet. They are no longer training new pilots on the legacy model, rather sending them to the states to convert to the F35.
The Marines just updated their APG-73s to APG-79s so I'd assume they'll keep them flying for some time.
Canada is obviously flying legacy hornets and just received 2 of the RAAFs post Ex Red Flag 19-1 (another ex I was lucky enough to be at this year).
Malaysia still flies the D models, they had theirs in Australia for Ex Pitch Black last year
And Switzerland, Spain, Finland and Kuwait all still fly their legacy hornets. Most of them are looking to upgrade to the Super Hornet, but time will tell what happens there. Currently only the RAAF outside of the US fly the Super Hornets and the Growlers. From what I've heard Canada is still pushing for Supers and Growlers as well even with the RAAF hornet stop gap.
Anyway, you can expect that the legacy hornet will still grace the skies for a while yet.
