How do you release countermeasures?

[WildBillKelsoe]

Its weird. Latest update, I set it to both chaff and flare, and flick the switch by canopy handle to INT/KONT (which positions?) and OFF yet as I press HOTAS countermeasure fast release nothing happens.

 

Can you walk me step by step or maybe I wasnt packing chaff or flares?

 

Also, can it detect IR MANPADS or just radar guided missiles?

 

State of sim?

You need to add the countermeasures pod if you want to release countermeasures. The AJS37 doesn't carry any internally.

Not sure what you mean, the RWR will detect radar signals.

Like A-10C can detect SA-18 igla?

No, only the A10C and M2000 have this ability in game now.

No

 

The Saab AJS-37 Viggen only has a RWR that is a RADAR Warning Reciever, something fires a radio/microwave beam at it and it goes beep. The Viggen's RWR is simple, it only gives you direction based on a 6 sector system and it can only give you PRF (pulse repetition frequency) in that the frequency of the beep corresponds to PRF of the RADAR, you can use the pitch of the beep to best guess what kind of RADAR is being picked up by the RWR.

 

The SA-18 is a passive infrared guided missile, it tracks by way of tracking a source of infrared radiation which will be your aircraft. It doesn't emit anything to your aircraft like a RADAR does so the Viggen won't tell you if one is approaching.

 

The A-10C has a more sophisticated defensive aids system that incorporates not only a RWR (and a more sophisticated one at that) but also a MWS/MAWS system, that is Missile Warning System or Missile Approach Warning System, this is like your eyes visually spotting missiles, though with a bit more sophistication. The A-10C I know uses the AN/AAR-47 to warn you of incoming missiles, what variant I don't quite know. But they use either infrared/optical/UV (somebody who knows what they're taking about correct me) to detect incoming missiles in sort of the same way your eyes do. The Viggen sports no such system so is unable to detect incoming missiles, the only way to do it is to use the RWR, which I don't believe gives you indication of a launch, but I might be wrong, or to use your eyes.

Someone in the industry once told me that the main method for detecting an incoming IR missile is UV. As I understand it, the sensor looks for a combination of emissions in the IR and UV that resembles the exhaust of a missile's rocket engine, figures out what direction the missile is by comparing the signals from different sensors, then displays a warning to the pilot.

 

How it decides what's a missile and what's not, categorizes threats, and otherwise 'works on the inside' he couldn't tell me (all super classified!). Apparently the Americans won't even let you open the boxes that contain the equipment for repairs- if it breaks you send it to the US (presumably on secure air freight), and a couple of weeks later the device (or a replacement) comes back, fully functional.

 

I do find myself wondering how many high tech sensor systems have gone on trips halfway across the world to have a $0.05 resistor replaced... But that's just how the US defense industry works with classified equipment. They're not very trusting people :D

 

 

On-topic, the flares are dispensed from the Viggen's countermeasure pod using the 'Countermeasures fast release' control, which needs to be assigned to a button on the keyboard or a controller (it's not clickable in the cockpit). They're not really that effective because the dispenser only launches one flare per second (or therabouts) which isn't enough to distract most IR missiles before they reach you. Still better than nothing, I suppose. AI Viggens cheat: they can launch flares from both wings without carrying any pods, and whenever they do so I turn green with envy.

[WildBillKelsoe]

I see. Now I know about the mws which is great in A-10C. That classified information could get you killed or expunged dishonorably from the military! RUUNNNN!

Also, in a rather twisted sense, the lack of a clickable cockpit switch actually turns out to be accurate since some sneaky evil spy has seemingly replaced the canopy countermeasure switch with an emergency radio transmitter/receiver.

 

Granted, that's probably just the devs having old or wrong photo references, but still. :lol:

The switch label is accurate... for a JA 37. It's the same switch in the same place for both aircraft but on the AJ and AJS 37 it controls countermeasure release mode and is labeled as such, but on the JA 37 it's some backup radio transmitter mode setting (IIRC controls if the push-to-talk button on the stick should transmit on the backup radio or not, or something like that).
