Until the first F-35s arrive
Russians and their Novichoks say that they are fighting NATO but better NATO stay out of the conflict. Would be funny to see strikes against RU refineries by F35 which Russia can't even detect.
It's 2024 outside, and Poland is still clinging to its Soviet rust buckets.
As with tanks, logistics of keeping multiple fighter types operational will eventually be too much, sanity will prevail, and all these Migs will be eventually delivered to Ukraine.
When it comes to tanks, due to impulse buying, Poland ended up with T-72M, PT-91, Abrams, Leopard 2 and South Korean K2. MoD people on arms fair shows were like kids in a candy store.
Good thing that Poland sold well maintaned T-62 and T-55A to various African nations in the 90's, where these distinguished machines got a second life liberating good black people from bad black people.
T-72M were transferred to Ukraine in 2022, and I believe most of PT-91 are currently liberating Kursk People's Republic.
Otherwise - maintenance teams in armored brigades would go insane.
