ABM engagement issues (terminal seeker equipped SAM missiles) unable to intercept ballistic targets in terminal phase

[CarlTheRadarNerd]

New update is really great. But updates sometimes comes inevitable bugs. Currently only TVM/SARH are only capable of terminal phase ABM interception. Missiles using active radar/infrared seekers or combinations cannot intercept ballistics.

Situation - certain units/dedicated SAM facilities that use terminal seekers like ARH or IR do not automatically engage ballistic threats at the terminal stage of its flight. For example, only TVM/SARH seem to engage ballistic missiles in tests, such as PAC-2 and S-300 series (48N6 series only/TVM) currently function properly along with other SAM using TVM guidance. PAC-2 GEM+ and other SA-20/48N6DM work - as long as its TVM.

Other terminal ABM systems such as Stunner (David's Sling - ARH/IIR/EO seekers, paired with a dedicated ABM radar mount) says "unable to intercept target" for ballistic missiles it normally would intercept before update.
Same with the SAMP/T using Aster 30 and Aster 30 block 1 NT and S-400/350 using the 40N6E or 9M96E2 (active radar guidance)
However, PAC-3 missiles sometimes work for ABM role , and other times do not.

Issues also exist for some other SAM facilities that use terminal seeker equipped missiles when dealing with high speed/ballistic threats.

SAM facilities having issues engaging terminal phase ballistic threats: error message "unable to intercept target", even though target speed within parameters and guidance radars have sufficient track of target for ABM engagement:
PAC-3, SAMP/T, David's Sling, SA-21a/b, SA-28 (S-350 Vityaz), Skybow

Not sure if bug is due to guidance radars or missiles themselves, but prior to the recent db update each system's ABM function was working fine.

Do you have a scenario that was working reliable with ARH and now it's not?

I've tested the pac2/Pac3 of the other thread scenario and, Pac3 hasn't problems to engage TBM. Also if I added a TPY4 to the sky bow, they were firing too (with less pH due to the speed of RV)


Thank you

Thank you

Maybe you have a savefile with a working PAC3 and /or Sky Bow engagement TBM? I can not manage to fire a single PAC3 or a Sky Bow with TPY4 so it would be very interesting what is the reason. Thank's

Newest 1706 Beta seems to fix this

Fix how ? What is different?

Just wanted to add on something I noticed.

When playing REDemption Part 6 from the community scenario pack, noticed some strange behavior on the opening missile attack on Starokostiantyniv airbase about 7 minutes into the scenario. After the missiles are first detected, they do not seem to be tracked consistently, about every 2 seconds the radar is not tracking them for about 2 seconds. This sequence continues which usually makes it impossible for the Patriot battery at the airbase to get a shot off. Occasionally it does get a shot off and for some reason prioritizes using the PAC-2 missiles but sometimes will use both. If it does get a shot off, the radar switches modes and the updates are more rapid.

If you attempt to manually intercept the incoming missiles, when the incoming missiles are being actively tracked, the PAC-2 missiles usually allow manual fire but the PAC-3 missiles do not, with a simple "Unable to intercept target" as the explanation. I found that odd as the PAC-3 missile should be a better interceptor against a ballistic missile.

I setup a basic test scenario to see if it was scenario related. While the radar seemed to keep a better track on the incoming missiles, the Patriot battery still seemed to have difficulty automatically engaging the incoming missiles. Again, manual intercept gave me the same issues with the PAC-3 missiles, however, it did occasionally get several shots off of both the PAC-2 and PAC-3 missiles (though the results were usually pretty poor).

I also noticed some strange behavior with the PAC-2 missiles in both scenarios on occasion where they would be tracking towards the target and at some point it would make a left turn away from the incoming missile and never intercept the target.

2 Files attached, in the REDemption scenario, advance about 7 minutes in, in my scenario you may need to advance it a few seconds before incoming missiles are detected. I have run it over and over again and get different results, Occasionally it fires and intercepts the missiles, other times, it doesn't or never gets a shot off. The REDemption scenario seems to be more consistent at not even getting a shot off. Of note, the database versions are a bit different but don't think that would have an affect?

Hope this info helps as I don't recall seeing these issues playing the REDemption scenarios previously.

What version of the game are you running? We've made some significant BMD improvements on the beta branch with 1706, and I'm unable to recreate any of the issues you're reporting.

The PATRIOTS being able to fire beyond their max range with manual allocation is WAD, just know that if you do the missile be dramatically less accurate since it will be hitting the target at a much slower velocity
