You will rarely if ever achive that speed with them in game. Infact pretty much every missile in game will very rarely reach its max listed speed.
The only time you can ever get them to go close to that fast is if your launching at 8-10km in altitude while going fast. Which given the average map size and general gameplay of WT top tier air that scenario rarely happens…
Insane that even when ARH drops and nato gets arguably the best one there’s still a SARH that scares people to death.
Seriously though, 120s can guarantee multiple kills while the 27 can only go for one at a time. My advice is to abuse that fact
People see statcard and assume it will be that like always (while statcard tells perfect case scenario) and it quite literally saying maximum speed, not sustained speed or anything else.
by those means the phoenix A is the best missile in the game for you for the sole fact it has an internal radar at the lowest br, even if it is missing 90 percent of it’s acceleration and pulls like a red top.
More accurately, the radars on the Aim-120 (and other ARH) are modeled to be pretty weak and unlike IRL, stop recieving DL information from the launch aircraft upon reaching their active range. These radars are just as easy to defeat as any early radar.
Defeating R-27ER or other SARH missiles invovles defeating the aircraft radar and at higher BRs, they can be incredible hard to defeat and will quite happily ignore chaff altogether
If anything, played right the R-27ER vs the AMRAAM A can result in a mutual kill but very rarely should the R-27ER outdo the AMRAAM except for in that sweet spot where the R-27ER’s stupid good accel can propel it forward to kill the target before the AMRAAM can go independent. But even then the risk is high for a mutual kill
