Yeah, if the crew was the weak part then why increase the volume of space inside the aircraft dedicated to their comfort. Removing them and replacing them with something else would be the upgrade if they were the problem... not expanding their footprint inside the aircraft.
Su-34 is a Soviet concept.
The misión of Su-34 is long range missions in a scenario of high scale war against NATO. This is tactical nuclear strike against western Europe countries.
They likely wont make more than a couple of dozen more Su-34s as they have in service over 120 right now, so it would make sense as production of Su-34s wind down to start production on something else.
In this moment, after the withdraw of the 5 Su-34 of the first batch, and lost 4 (3 in the same accident in january 2019) , there are 113 Su-34 in the ranks of VKS
By the year end , VKS will have 120 machines in 10 squadrons.
Other 90 Su-24M and Su-24MR are in service in VKS and 24 in Monchegorsk under the command of North Fleet.
Total more than 110, that need replacement. Also Pacific Fleet will be rearmed and probably will receive the same than North Fleet.
Su-34 will continue in production until the total replacement of Su-24M, about other 60 to 72 Su-34
The Su-57 can engage the F-35s while the S-70s take out the C-130s behind them.
Su-57 is the counterpart of F-22. The misión on RuAF is the to defence of mainland in the three main directions : Leningrad, Rostov and Jabarovsk
The number of 76 Su-57 is not a casuality. USAF has 166 F-22 in 9 squadrons of 18, +4 for training.
The most that USA can deploy outside is 4 squadrons or 72 F-22
F-35 is a joke, will have to see in the end how many are manufactured of the 2700 intended-No more comments.
And C-130 will be easy bread for Air Defence, S-400 or S-300, if invades the russian air space
