Cmptohocah Posted March 7, 2022 Posted March 7, 2022 (edited) Just saw this video and it looks like R-77-1 has a range of around 90km!? The video shows Su-35's HUD at the moment of firing an R-77 ARH missile. Launching aircraft is doing M0.95 at around 12.9km altitude. Strangely, I can't seem to tell speed and height of the target. It looks like it might be also lofting, but unless someone figures out the target's altitude this is just speculation. Edited March 7, 2022 by Cmptohocah Cmptohocah=CMPTOHOCAH
Tom Kazansky Posted March 7, 2022 Posted March 7, 2022 Are you sure the target is 90 km away? It seems odd to fire from that distance with such a huge off-boresight-angle.

FoxAlfa Posted March 7, 2022 Posted March 7, 2022 (edited) You are using Rmax wrong... it is R1 and R2 ranges in Russian manuals.... so Rmax not necessarily equal R1... especially since manual instruct pilot to fire R1 which would be exceptionally low probably shot if Rmax = R1. Edited March 7, 2022 by FoxAlfa ------- All the people keep asking for capabilities to be modelled.... I want the limitations to be modelled.... limitations make for realistic simulation.

Ok, fair enough, so what is the R1 here? To my knowledge R1 is exactly the same as Rmax, but I am ready to be corrected. Cmptohocah=CMPTOHOCAH

Target is probably the one marked with 1 on the HUD, well below the horizon, so seems like it does loft. 1

R1 is not the same as Rmax since there are engineering safety include into calculations, like wind, trigger passing speed, temperature, hit probability etc... Also some pilots stated that missiles should be able to pull 3g for more then few seconds pass R1... That is why Rmax > R1... 1 ------- All the people keep asking for capabilities to be modelled....

Badger1-1 Posted March 7, 2022 Posted March 7, 2022 Well anyway he is shooting it at around 80km which is around 43nm and hes at around 40k so...all normal? It just shows what an immense range the phoenix has

From what I've heard and read so far, the limiting factors are available terminal manoeuvre G's, missile speed needs to be higher than launching platform speed at time of impact, overtake speed over target (important for rear aspect shots) should also be enough for the fuse to work properly. These limits will also probably differ depending on missile, launching platform and intended target
