I mean not really… Su-25s have proven to not really be needed in a war like Ukraine but that doesn’t mean they need to get rid of them entirely, especially since most of the ones they operate are SMs…
now something that SHOULD be gotten rid of is Su-24M/M2…
Probably to keep quantity. In areas with less anti-air desnsity Su-24M2 can drop UMPKs just as fine as Su-34 so you can keep 34s on more dangerous missions while having more aircrafts overall
If wikipedia to be believed, by 2024 only 12 Su-27s were left in Russian airforce and 18 in navy. Rest are all modernised to SM or SM3 standard. Not a sinle 27P mentioned.
Visually there is pretty much no difference between 27S and 27P so those 12 mentioned could be the last airframes. Other than that, from what i heard, SM and SM3 are the ones that get distributed to PVO, while 35S and 30SM are saved for regular airforce units.
i run universal, APHE does very good damage if it fuses, and with modern airframes there is a plenty of opportunitioes for it to fuse, but you still keep HEF-I in it just in case.
