R-33, R-37 and R-37M are all broadly comparable to AIM-54 (and Fakour 90) in size and mass.
Not quite as absurd as AIM-174, but very much on the larger side for A2A weapons. I don’t have data for the G loading of the R-37, but it’ll need quite high values to be difficult to dodge at speed. 25G at Mach 1 is vastly different to 25G at Mach 3 or higher.
Even 50G at Mach 5 will be a very large turn.
