I discovered that all the hypersonic cruise missiles in the game have a problem of excessively low turning rate (much lower than that of HGV, almost completely straight and unchanging at a scale ranging from several tens to about 100 nautical miles). As a result, the HCMs with anti-ship capabilities (such as AShM HAWC, YJ-19, CJ-1000, Zircon) are unable to effectively aim at the target during the terminal locking stage (ASBM and ASHGV, such as DF-26D, DF-27, do not have this problem).

Incidentally, in my DF-26D bug report, a friend said the CJ-1000 missed its target and made a long detour before re-locking on the target. This situation should be related to this one.

I added target ships and a carrier moving at flank speed, the missiles (Zirkon, YJ-19 and CJ-1000) and impacted without problems or detoured as you described.

Another problem, perhaps related with it or due to the high speed, is when you plot a course. In this case the carrier was stopped.

Perhaps this is useful to solve the problem. The detour is due to a reattack after the radar seeker has been spoofed, it is a long detour due to the high speed, and will try until running out of energy. WAD?

I think plotting a course is a different problem and probably due to the high speed, will create a new thread.

The retargeting of the 3 HCM in the scenario compared.

The CJ-1000 is the longest one, it is also the faster, and so has more difficulties to turn, WAD?

This problem is more likely to occur at a greater distance of engagement. Moreover, the DF-26D and DF-27 have much higher speeds and do not have such missed-target situations. They will quickly correct their trajectories (this can also be seen in the strict adherence of the DF-27 to the waypoints).

But the DF-27 RV may also fail if the radar seeker is spoofed.

This is exactly the same of what happens with the 3 HCM in the messages logs posted above.

The advantage of these is that they may retarget, but the DF-27 cannot because it is ballistic.

I see a problem in the plotted courses of the HCM, but not in the aiming of the radar seekers.

HCM waypoint issue logged as 0017390. Spoofed missiles attempting to re-attack is WAD for now

What I want to convey is that the reasons for the failure of HCM locking and the reasons for not following the plot course are the same. If you start to slow down the time flow rate (for example, to 2x) and magni-scale, before the missile activates the radar guidance system, you can carefully observe that the HCM itself will make very small and low-frequency turns. However, this turning rate is insufficient to ensure that it can accurately hit the predicted target point (just like it cannot follow promptly to the plot course points).

P.S. The surface ship target I use had no jammer or decoy.

I still do not understand, the HCM will impact the target except when is spoofed or malfunction, like the rest of weapons.

I have seen many times torpedos that in the map you may say following the trajectory that it will not impact the target, and suddenly, boom, the target explodes.

It is run by a roll of a dice, if the weapon is not spoofed or malfunction the target is impacted.



There is no target in the scenario you uploaded

This ".save" file has recorded the entire process of my bug testing (the development team can view the record), rather than a initial state. I suggest you create a new blank scen, set a ship target without any jammer or decoy to be in the "autodetectable" state (so that you can aim at it without relying on other sensors) and move it at cruise or flank speed. Then follow what I said above, and you will discover something.

Well, I discovered we have different B1892.

The ML of your scenario.




What happens here after creating a new scenario with your conditions. Sure they may malfunction, but this message is different of yours.
