Su-27 doesnt really need it’s Radar as much though as it thrives in the short to medium range late game. It’s weapon systems are designed as such R-77 and R-73 and even R-27 are all pretty lethal in short range.
Typhoon really needs to be able to use it’s Radar to make that limited payload count.
We are also comparing an older mechanical scan Radar with the most advanced mech scan Radar in the game.
Having the screen on a single eye is a slightly more considered choice than it seems. It allows for a sense of distance (HMDs can cause a “flattening” of what you see). Having it on only one eye allows you to have both the information and this perception.
Furthermore, the system can be moved on the helmet, allowing it to be positioned in front of the pilot’s “aiming” eye. And since the way you see things is based on this eye, it doesn’t impact the perception of information at all.
Considering the Striker 1/2 HMD and F-35 JSF HMDS all using a full field of view HMD the idea that a monocle based system is advantageous seems not to hold water.
As @ron_2303 mentioned its old 80’s tech, sure the newer symbology is there on newer systems like the JHMCS II but you’re still limited in field of view pretty massively. Which means you need to move your head/neck around more.
I never said it’s advantageous over the full-vision system; it’s a technology that has advantages and disadvantages, and more modern systems are obviously more efficient.
Moreover, what I mentioned about the advantages of the eyeplate display doesn’t apply to more modern systems because they are systems that project onto the visor and not onto a plate (as in the case of the F-35). Technological developments in displays and materials have made it possible to reduce the flattening effect on these viewfinders, which is why the new models achieve this result.
