Just unlocked AIM 120B and pretty disappointed how they just nose into the ground if the target aircraft dives. It’s like the seeker is locking the ground and not the aircraft.
They seem to be massively over leading targets. I know we shouldn’t compare DCS, but AIM 120 in game are not so easily defeated
Such is what happens with proportional navigation, and it definitely happens in DCS it’s a big way to defeat missiles.
Diving on the deck can work but the missile is aiming for the deck you have to lead the missile i’m watching jets just lazily dive to the ground and the missile gives up.
4 miles from an AIM120 you aren’t defeating it
It seems pretty stupid for a missile that likely has a built in radar altimeter due to its seeker tbf… I’d be incredibly surprised if fox 3’s irl did not cancel normal prop nav when it would lead them to colliding with the ground, choosing instead to follow LOS until target no longer has an estimated intercept point that intercepts a massive chunk of radar clutter…
Nevertheless, there are methods that prevent missiles from doing this.
SA2 system could already do this in the 60s.
In the BMS, the AIM120 does not simply fly into the ground
Do we have data on RCS for aircraft and how the missile interact with that value?
Seeing some weird things with the AIM 120B
Can you elaborate on what you find weird?
I find US aircraft seem to be able to spook or fool an AIM 120B launched frequently within 10km of an F-16 and the missile misses (its on its own radar and its not being notched)
Su-27 die, Gripen die, Mirages die. But F-16s and F-15s Amraams give up (for me flying the Tornado)
Like you are tyring to shoot down an aircraft with a very low RCS
I have no issues fooling AIM-120 with either, you’ll have to find a way to show that similar sized fighters with similar sized flares are getting unique responses from the missile for a report.
I will look at the sensor view and see what’s happening
It is normal that they are different for such different missiles. PID values dictate how much the missile tries to correct to hit a target. Tuning values, basically.
AIM-120 absolute maximum speed in-game per the files is mach 5.08 (1500 m/s) at very high altitude. The top speed of the missile should therefore be achieved at a minimum speed of mach 2.1 at 12km altitude. The loft profile should bring it into thin air relatively quickly. A higher launch of 2.4 mach should bring the missile to a theoretical top speed IRL closer to 5.1 - 5.2 mach.
In the case of the R-27ER it is missing a top speed of 100 m/s from 5km+, I think in-game the AMRAAM is much closer already to its’ real world top speed in comparison and may even be overperforming in very low altitude scenarios (as is the R-27ER and other longer range AAM’s).
The 27ER, much like C5 is missing top speed to the engine limit isn’t it? Same for 120B, they all clip at 5400km/h IAS(iirc).
Any missile with a top speed above 5 mach at altitude would hit the limit, yes, hence my comment. The R-27ER is missing 100m/s from it’s top speed as early as 5km whereas the AIM-120B is only missing speed when launched beyond 2 mach and at very high altitudes.
Yep, i really hope they fix this limitation. A it would buff the R-27ER and pose more questions on which aircraft use it, for potential historical changes, and some missiles like ASRAAM will be heavily capped by such a limitation if it isnt removed.
All future ordnance that can be added to the game in regards to medium or long range AAM’s are hampered by this limitation. Any that are not are sparse exceptions, such as AIM-7P.
Pretty much, especially with the Russian hypersonic missiles which can really offer a unique capability to Russia, I would expect it to be fixed pretty soon.
