PRF code setting for LGB in single player with AI JTAC

[DmitriKozlowsky]

In RL PRF codes for laser guided munitions would be pre-briefed as part of mission operations order. But I am unable to find option for JTAC to use a particular PRF for LGB, and I am unable to find how to set PRF for AI armorers in Mission Editor. Is PRF even a thing in DCS: F-5E? 

F-5E in DCS, is really a fair weather aircraft, with no ECM, and way too few countermeasures. But its a decent rocket delivery platform. Evading ZSU-23 and ZSU-57 , and 40mm Bofors , not difficult. But modern SAM in DCS, SA-15, SA-19, all MANPADS kind of eat F-5E s (flown by me) for lunch.

AIM-9P5 is almost as good as AIM-9M, it will guide at all aspects, but it seems very easy to spoof with flares. Especially by TU-95 and TU-22M. Even firing from 5 or 7 o'clock (from enemy POV) at Bears, there is a good chance that Bear's flares with spoof it. Combined that we only get 2 Sidewinders per sortie.

I see we just got Chinese H-6J. A modernized TU-16 Badger. Thats an interesting target.

JTAC changes to equal the airplane code. He might handle 20 airplanes with 20 different codes. The fact that DCS JTAC is inflexible in LGW code is a hole in the simulation. I thought there was a way to set the JTAC code in the editor but I don't see it. You get what you get and that's it.

 

Yes, laser-guided weapons with codes is a thing with F-5E. You can change it with battery switch off on the ground through the kneeboard.

Unfortunately, DCS' JTAC doesn't support changing laser PRF codes, and always uses 1688 AFAIK.

 

On the F-5E-3, you'll find the setting either in the kneeboard (so long as the aircraft is cold) where it can be changed, or alternatively, you can find it in the "Additional properties for aircraft" tab in the mission editor, this is where it also is for the M-2000C, F-14A/B and F-16CM (and probably others).

 

Personally, the changing of the code should be made a ground crew option, either as a separate option or as a part of the rearming and refuelling window.

It was a lightweight tactical fighter, mostly intended for export, from around the 70s, it's no surprise that it struggles with air defence systems from the 80s and 90s.

AFAIK the AIM-9P-5 AFAIK uses a cooled InSb detector, and I think uses a spin-scan tracker. The AIM-9P-5 apparently had improved countermeasure resistance, but not sure of the particulars. But owing to the AM spin-scan tracker, it would be expected that it would have poorer countermeasure resistance compared to the FM conical scanning employed by the AIM-9M, which further has electronics designed for countermeasure rejection (possibly by measuring energy rise).

Fairly sure that's accurate for our version (though IIRC our version is somewhat of a mashup).

Yeah, but it's from 2018 AFAIK, a much more suitable target would be the baseline H-6 or Soviet Tu-16s/Tu-22s/Tu-22M-2.

Tried with TU-22M. If TU-22M is at high altitude, at its max DCS speed with or w/o burner, F-5E can't climb and catch it in a chase intercept. Its too slow. To intercept Backfires, F-5E has to come from Backfire's 9 to 3. With only single two missile shot and head on and single high aspect merge for guns. After that its waste of time, unless TU-22M is forced to slower speed, by mission designer, or damage. Now Mirage 2KC, is a great Backfire interceptor. It can catch em from any aspect. I am sure DCS F-15C is also, but its an FC3 not DCS level. F/A-18C is great for blunting med and low flying Backfires.

We have the Tu-22M3, which is faster than the M2, by a substantial margin, and it's a bit more suitable for the F-5E, then again so would the Tu-22 Blinder and Tu-16 Badger.

The ability to avoid SAM’s is more on the pilot than the plane, especially modern SAMs. You need to learn the firing parameters for each and avoid getting inside them. Stay out of the WEZ and the SAM won’t fire.

 

If an SA15 or 19 does fire, you need to head for the deck fast enough to cause the SAM to hit the ground.

 

MANPADS are a matter of speed and angle. The F-5 is plenty fast enough to stay out of their firing parameters. If they do fire, a couple flares, throttle to idle and a proper break usually defeat them in any aircraft.
