In this case are some guys who likes the SU-33 in several squads, the 33 flight model dont have the S option of the SU-27, at the same time, have less fuel and countermeasures, if the SU--33 goes with ECM have the same missile quantity than F-15, that can have:
- 10 missiles
- 3 fuel tanks
- integrated ECM
- Super airframe, never break the wings even with full loadout and stupids 14.5G maneuvers
- better SA, radar, and missiles
Then, why bother for what the others want to fly?
