TWS Mode for Flankers ;) Can they only select 1 or a multiple order like I seen some US planes do?
Sure I seen TWS on F-15 which can remember 4 targets in order to be ready to shoot when in range by SOFT LOCKS? Can this not order them for Flankers?

I know one MIG-29 can use TWS2 but is for shooting just 2 missiles at 2 Targets one after another but not simultaneous right?

In DCS is the SU-27A. The oldest version of flanker with the oldest avionics. It does not have TWS.

About the 29, there is also the A version which can not do that as I know.

I guess it is done via missile command. The missile is just commanded from aircraft.
Fulcrum and flankers in DCS have TWS available, but it automatically switches to STT within 80% of max range, iirc.

As for the fulcrum, it also has TWS2, which allows you to lock on two targets at once (they need to be flying close together, though).

Once you have TWS2 lock + cross (for second bandit), hold the weapon release button, that will launch one R-77 at each of them... problem is that it'll be a DTT lock, so they'll probably get instant missile warning.

In other words, you're better off using EO.

Yes all Flankers have TWS (not restricted to Fox1) but I was interested in the SOFT LOCK (the dotted box before you or it goes into a HARD LOCK). So it is just the F-15 that can set 4 Targets in SOFT LOCK I take it.
I now see I can Target 2 planes in TWS just as we can with the MIG-29 TWS2 but how are they different? In TWS (all Flankers) it numbers them the 2 Targets 1 & 2 although I did not yet test this for firing. I have seen the TWS2 vid but forget which MIG-29 type it was on.
The F-15 is weird in TWS which you select your 1st but has no label for that Target, then you can Target another 3 it labels 1,2,3!

I'm not surprised many pilots are very confused over Russian Planes. Every one thinks you need CANOPY OPEN to Refuel/Rearm but you DO NOT. The ONLY difference being is you can HEAR the refuelling.

You don't need to HARD LOCK (STT) until you really wish to. All you do is let the box auto move to the 1st Target then do the same to another close to it and it will lable them 1 & 2 in SOFT LOCKS. Once you are then in firing range it switches by auto to STT HARD LOCK (Circle).

So I can lock 5 or more Targets in TWS with any Flanker. So what is the point?
Once we fire our 1st Missile there's only the Fox2 that would not require keeping a Lock until Kill except the R77 in J-11A for the R77 for half of it's path.
How do we select the Next Target in our List we ordered???
If it means waiting for the Target to be killed then it first must hit the ground!
Else if we use UNLOCK TARGET bind OR reselect BVR, it keeps TWS ON but has lost the order of Target List we made!!!
So what's the real point in this LIST???
Is it to label them on RWR so we can tell Wingmen (AI & people)???

According to the manuals. The R-27 and R-27ER missiles have a semi-active and passive lock. So even if you stopped locking your target with the radar, the missile will lock on target's radar and/or on target's ECM. This is what is written in the manuals. I didn't checked it. But again, if you using TWS mode, whan will happen to the first missile when your radar will lock the next target? Will the first missile continue aiming on the first target or will it reaim on the next one? Also, it is may be, that the radar of SU-27/SU-33 have an ability to lock and track 4 - 5 targets simultaneously? If it is so, it makes sense. I know, more questions than answers, but everything about russian planes are mystery in this game and must be checked to know it for sure.

By the way, the AIM-120C have the same ability. Like if it's radar loose the target it can switch to passive mode to re-aim on target's radar or ECM and then switch to active mode again. So it maybe better to turn off your radar and ECM to shake this missile of your plane. But again, it's according to the manuals, but I don't know this for sure. It need to be checked, but I guess it will be very hard to check.

Where did you get that from?

You can TRACK several targets in TWS, but you can't fire at them.
STT is required for weapon employment, so you can only engage one target at a time.

The fulcrum's TWS2 allows DTT, which means that you can engage up to 2 targets simultaneously, that's the difference.

Btw, I think that DTT is still a hard lock, so both bandits will get missile launch warning.

That's how the fulcrum's TWS2 works, but the flanker can't do that afaik.

Also, I don't think TWS2 locks are "soft".

No, you can TRACK up to 10 targets, which isn't the same thing.

TWS tracks don't allow missile employment, again, you need STT lock for weapon employment (which is why it switches automatically to STT within ~80% of max range).

What list? Are you talking about HDD symbology?

Afaik, there's no TWS list for these planes, this mode is only meant to keep track of several bandits, so you can STT them one by one without having to look for them.

If the purpose of this thread is to know whether you can employ the flanker's and fulcrum's TWS modes like you do in the eagle, the answer is no.

Like I said, if you want to be "silent" you're better off using EO

What manuals are you referring to? Flanker DCS manual?

Are you talking about this ?

"Nevertheless, it is possible to obtain a bearing-only "angle-of-jam" (AOJ) lock on the countermeasures strobe and to launch semi-active radar homing (SARH) missiles, which in this case will guide in the passive "home-on-jam" (HOJ) mode."

That only works if the bandits are using ECM and I doubt the guidance is any good.
I wouldn't expect to hit anything using HOJ, tbh.

You just need the hard lock to be able to shoot at target, because SU-27 can not carry and use R77 which are the only one that are usable in TWS2 mode in Mig-29. The main reason is because the R77 has active guidance. R-27 has semi-active.

Yes, I'm talking about DCS SU-27 manuals. It is also written in MiG-29 manuals. The manuals says that the missiles AIM-7M, AIM-120, and R-27 have a Home On Jam (HOJ) mode.

In the Mig-29S with R-77's, you can go into TWS2 and if two enemies are close enough, you can move the box cursor over one, then it will put a crosshair over the second one (takes a second or three). Do not switch to EORL mode or you can only track one, it must be in only "RL"/radar only.

You can then wait until you're close enough and it will auto-lock (not quite sure what kind of lock this is, yet) or press the "Target Lock" button (you can do this at any time, long before you're in range) and then you can see both targets on your HUD (Their physical location to be specific). One will be the small diamond that you're familiar with. The second one will be covered with a crosshair. Then, as soon as you get into the first acceptable launch parameter, LA will pop up with a T1 and T2 on each side of the LA. Just fire missiles twice (or more), it will switch back and forth between the one it's firing at. It also begins to number the missiles but I need to fly it and pay more attention to say more about that. Also, I haven't ever been in a position to see if it can track more than 2x jets nor have I tested any of that.

I need to see how this works with R27-R/ER's. I can only guess that it works like the AIM-7 does in the F-15C or F/A-18C and that it requires an STT lock to fire and can only track one target instead of both like it's doing with the R-77's.

The LIST I mention is the number order of Targets in the HDD. Due to the ingress speed we need to get an advantage for faster missiles, these numbers only show up for about 1sec and can only be seen when ZOOM in on it and at best Display Zoom too obviously.
So both SU-33 & J-11A with R77 can make best use of these once they go pitbull so that we can STT our next Target. But the Targets are all forgot once we either UNLOCK or reselect BVR right? Or does it auto-STT LOCK next on that list? It needs testing because there were times when it seemed I could not select any further SOFT LOCKS by moving to them. Perhaps it had gone over all 10 already?!
HOWEVER, there has to be a reason for the SU-27 to have this too. Is it solely to designate WINGS targets? Because we see ourselves as a number plus any Wings get another and we share on datalink all this data to see who has selected what. Is that the point here so that the first to arrive gets to use TWS for many targets to designate for our Wings to know what to go for? Makes sense! Then that's why it does all it needs to in a split second. If left to fully auto TWS it just selects the closest in a group of Targets. That's ok say if on your own against them from behind else pick another day to fight lol ;)

For Flankers the average maximum kill range being 10miles and breaking through ECM is about 15miles then it is possible to not be pointing towards Target when firing and the missiles can even be fired even closer whilst on the defensive (hit deck or corkscrew works). You will know if to use those when it still says JAM but you can't see that when using EO so would require EOIR for radar ON.
