Wow they’re so lazy
Its super easy to test in a user mission or a private match, simply have two planes flying in a line at the same speed, lock the rear one, then have it slow down while the forward one stays the same speed, the missile will shift its lock to the forward one.

Does AIM-54C actually reach mach 5.7 in dev server?
Considering that there is barely a reason to use Phoenix below 8-9 km of altitude, that’s a pretty significant buff.
It’s 4000m to match old thrust, but 9.6km to match old total impulse, because total burn time went from 30s to 27.8s. But if your missile hits before 27.8s, then yes at 4km altitude it’s already better.
For exact matching performance it’s more complicated because drag (slightly) and loft changed. According to the graph, the multiplier does assume linear scaling with pressure (I think), but that of course doesn’t scale linearly with altitude.
But total old impulse was ~14350 N * 30s = 430500 Ns, so to match that in 27.8s you need ~15485 N of thrust, which on the graph is around 9.6km.

Is it correct for the missile to be as draggy as it is in the dev server?
It feels weird with how quickly it loses speed after the motor shuts off to the point where in my testing launching at 9km altitude with mach 1.6 the thing can barely fly 50km
That’s because the flight profile is still incorrect.
AFAIK, the AIM-54 is designed to execute an aggressive loft immediately after launch, cruise at high altitude as it approaches the target, and then dive almost vertically during its terminal phase.

Here are the Code Screenshots that have been sent, BOTH Aim-54C and Aim-120 have DopplerSpeed/DopplerSpeedGate, but 54C and 54C+ specifically are missing Distance/DistGate which in War Thunder Provides Ranging Information

They also changed calibre , but i’m pretty sure they messed something with the drag as well. They changed it, but maybe did something wrong. Whatever shot you may make , the max speed is around 4 mach.
At 16km alt, the maximum it gives is 4,3mach when you launch with 2000km/h speed.
I believe that should be the 5+ mach they say in the reports…
And that’s with the 1,22% boost from altitude and in thin air.
At lower alt, with the same launch speed it barely reaches 2,7 mach.
That’s very wrong and i don’t think it’s the motor’s thrust.
Let’s start with it shouldn’t make 180s in any case… which they have video with 54 doing it .However it can do it when motor is on. I can’t see any other reason that it can pull 180… The motor has nothing to do with that. Or even the new fin AoA alone. You need drag to pull Initial D drift .
EDIT : it can give near 4.9 at 25km alt. launch …with 2,500km/h. Let’s say it should do that from a 15km launch , and 2,100-200 km/h launch. No F-14 would launch a missile at 25km alt and 2500km/h. ANd that was the only launching platform when they give info for the missile. If they got 5+ mach at high altitude documented , means the max is around 14s logical numbers, not MiG 31s.

At low altitudes, yes. The one correct thing TOPGUN told its pilots is that the Aim-54 is essentially dead in the water at low alt-low speed when the motor burns up.

To be fair they made it better with this patch going from 17.5 degrees of loft to 30. It should be variable to to ~60 but what it does do is condemn any plane with poor RWR zones to death.
That’s the maximum speed limit, which is part of a game design. It only caps the missile if it reaches that limit.
You need optimal launch conditions for the missile to reach high speed. That means launching at the highest altitude.

I believe loft is 22 deg now on dev, not 30
You’re right my bad
So is the motor burn time getting longer if you launch at 9.6 km or more? Therotically, if I can launch at the highest altitude, would the motor burn time be longer than 30 to 35 seconds?
No, the burn time is constant what varies is the thrust, at 9.6km now you get a total impulse of 430.5 KN·s which is the as with the old total impulse with the 30s burn time
I noticed that now AIM-54 can sometimes simply fly by its targets in headon conditions.

I see, thank you for the clarification.
11000m alt, mach 2, 45km target - couldnt hit the MiG-15 in test drive. Thats rough
