You should be fine with your Su-27 though. Just so you know, use caution when purchasing the M2000-C and any other new aircraft modules (even the new campaigns I think, idk, I never bought one.) as the keys are now completely seperate, steam keys for steam, standalone keys for standalone. I will be doing this when the F-14A/B becomes available. What many people end up doing is they eventually move off of steam and switch to the standalone version, this way when a new module comes out, they can buy and fly day one. A major example being the Viggen and NTTR (DCS World 2.0) are still not available on steam because they are both in testing. That being said, I want to make you aware of the fact that the steam version acquires these modules slower than having the Standalone version provided on the DCS website. You're getting into DCS World at a really good time, a lot of new modules are in the pipe and being worked on by different developers! Have fun with it! Hopefully you'll learn it and put in enough time to want to get the Su-33 when it's updated. That being said, it is still a very potent, agile fighter and a menace in the right hands. The Su-27, in DCS World or otherwise, does not have any of the advanced avionics of its later models. Likewise the Su-35 (upgraded, modernised Su-27) doesn't have thrust vectoring. What you saw in the videos was most likely the Su-37 which is a technology demonstrator and is not in production.

And I'm not sure if that's across the fleet or just select models. Originally posted by cailean_556:The Su-30 is the only Su-27 derivative production that currently possesses thrust vectoring.
