State test usually test the applicability, and capability of the aircraft in the VVS, along with making sure components reach the specs set by the
government, and is often done after the serial model is complete. If the PAK FA tests anything like the SU-34, the serial engine test should be done
quickly, it will not take 5 years. NPO Saturn is doing all the developmental testing at this time.
My question is, is this the serial engine or "item 127", which is the second stage engine on the research chain?
AL-41F1 >>> item 127 >>> unnamed serial model

I'm not an expert in this field, but both KS-172 and R-37, achieve their ranges differently. KS-172 was a very long projectile with very little drag.
The size and fuel load gave it its range, that's fairly obvious. R-37 has large fins that run along the body, they are there to create lift, the burn
time is controlled to optimize the glide range of the missiles.
Regarding ramjets vs solid fuel, I cannot say much. Ramjets have their engines with them for the duration of their flight, solid burns their fuel
probably loosing weight much faster. There are so many variables, you really cannot say which is the better, longer range method of
