1. the onboard RWR SPO-15 of Flankers has not been a reliable friend from its beginning, but the recent update in DCS 2.9 eliminates the possibility detecting when the active homing missile loses target. From the perspective of Flanker in defense, SPO15 is always barking as long as Flanker is inside front sphere of the activated missile seeker, not matter the Flanker is being tracked or not. It's been witnessed for so many times that anyone can repeat this bug from any PVP server. No matter I had evaded the seeker by terrain (some seconds after terrain cover, AIM120 was flying straight towards other heading, but I was still in its front sphere when there was no terrain barriers anymore) or by notching (barking all the way but I was actually survived in the end) ... even when the AIM120 had been firing in MAGDOG mode towards my friendly and triggered SPO15 when it turned around to my direction without actually locking on me. Tacview records are linked below. Two records are not convincing enough. If someone is interested, I can record the cockpit view mp4 as proofs.
I don't know whether other airframes are suffocating this bug or not. Please let me know if you had similar experience.
2. Modern airframes, like hornets and vipers, are able to fire AIM120s against jamming targets in TWS mode (without entering STT mode), which avoids lighting the SPO15 (only spikes are detected). I am not sure if this 'feature' is employed in LOT20 in reality but it's smart enough though for old ECMs on FC3 airframes.
For this part, I did not study it for a wide range of situations, so I am pleased if someone tells me I was wrong and explain the principles why HOJ mode is not necessary.
At last, as an old friend for over a decade accompanying DCS, I totally understand the need for bringing new airframes to keep the company running. Meanwhile, I think it could be better to look back and review instead of rushing recklessly. It is those 'unseen' but shining efforts that makes DCS a professional combat simulator
Thanks
