CA - SA-19 issues?

[LetMePickThat]

Hello all !

I'm having several issues with the SA-19 and Combined arms, and I can't figure out why.

• Sometimes, I can't lock targets using the PPI view (Rctrl+F10) whereas I have no problem using the optic (F1) view.
• When I do manage to get a lock on the PPI view, my guns and missiles are instantly brought up at maximum elevation, and do not lead the target properly.

See the enclosed track for more details. Any idea what I could be doing wrong?

Thanks !

I have noticed this too. IIRC you can get your gun out of the max elevation state by disabling or enabling the stabilizers (or was it tracking mode? ). It will then start tracking the target and you can fire the gun. However, for me, it seems that the lead calculation is sometimes (not always) way off. But using tracking mode and doing the aiming manually is way more fun anyways.

Whenever that occurs, I usually switch positions and disable/enable stuff randomly and it magically starts working again.

But thanks for bringing that up.

What exactly is tracking mode? I can't find any control with that name and I'm not sure what it refers to.

While I'm at it, is it possible to fire missiles using the SA-19 and the PPI (Rctrl+F10) view, or only the guns? Each time I switch to the missiles, the system will lose the lock and refuse to reaquire the target...

The command is called 'Track Target On/Off'

What it does is it takes the range from the rangefinder and adds lead based on user input (so if you range a target and then track it, it will add lead).

Do note that it's generic and none of the vehicles in DCS have their proper fire-control systems simulated (and the tracking RADAR essentially doesn't do anything apart from act as a laser rangefinder).

In DCS at least, the missiles are optical SACLOS, requiring you track the target optically. Not sure if the real Tunguska can use RADAR ACLOS (like Rapier with Blindfire).

In real life, the Tunguska and Pantsir are using ACLOS, with SACLOS being a backup mode. The ACLOS mode can be slaved to either the optics or the FCR, meaning that the system should be able to lock onto a target and fire at it regardless of weather and cloud cover, using only the radar if the operators want to do so.

It's disappointing that ACLOS isn't available, given that optical CLOS doesn't require much than what's already available for lead compensation when using the guns. That plus the single-target limitation (a glaring issue for the SA-15 for instance) make CA pretty much useless for any serious air defense.

I'm working on a Pantsir-SM, I might use a TVM guidance mode with tweaked guidance laws to work around that problem, given that the practical range of the missiles is much greater than what you could conceivably achieve with SACLOS.
