ED Team BIGNEWY Posted February 17, 2016 ED Team Posted February 17, 2016 why not? you may have to clarify your question are you in the su-27 with radar off and you get hit with an AIM-120?

Hydrox Posted February 17, 2016 Author Posted February 17, 2016 Yes. Isn't that missile radar guided?
BaconSarnie Posted February 17, 2016 Posted February 17, 2016 Nope http://fas.org/man/dod-101/sys/missile/aim-120.htm You might also want to google F15 Track While Scan And lo, Reverend Vegas did say "Take forth unto the infidel the mighty GAU 8 and expend its holy 30MM so that freedom will be brung upon them who knoweth not the joys of BBBBBBBRRRRRRRRRRRRRRRRRRRRTTTTTTTTTT" "Amen"
Hydrox Posted February 17, 2016 Author Posted February 17, 2016 So what was guiding the missile when it hit, if not radar lock?
RoflSeal Posted February 17, 2016 Posted February 17, 2016 So what was guiding the missile when it hit, if not radar lock? AIM-120 has its own radar.
Hydrox Posted February 17, 2016 Author Posted February 17, 2016 OK, can you tell me what's the point putting radar off in Su-27? Is it any use in game? Well except enemy knowing you're there, but with weapons.
ED Team BIGNEWY Posted February 17, 2016 ED Team Posted February 17, 2016 When you are using your own radar you will show on the F-15s RWR so by having it off you are denying situational awareness.

Sryan Posted February 17, 2016 Posted February 17, 2016 it's radar guided yes, specifically an active radar missile type. That means it has its own radar built into the missile that it uses to find you and hit you. It does not listen to the radar built into your nose at all. Another typical radar guided missile type is the semi-active radar guided missile. These look for radar reflections on the target caused by the parent aircraft radar. This is how the radar guided missiles on your Sukhoi 27 work ( R27R and R27ER). Lastly there are missiles that listen to radar signals sent by the enemy. They work the way you describe, if your radar is off they cannot see you. They are called anti-radiation missiles. they are not used against aircraft though, only against ground based anti-air missile sites. Check my F-15C guide
Hydrox Posted February 17, 2016 Author Posted February 17, 2016 Ok, that clears things up, I think I got it now. I'm gonna go kill that F-15 now payback time. Thank you for making me wiser.
winchesterdelta1 Posted February 17, 2016 Posted February 17, 2016 And there the adventure of DCS starts. Get ready for tears, happiness, despair, and adrenaline rushes :) Welcome Hydrox. Go in close, and when you think you are too close, go in closer.
Sheepherder Posted February 18, 2016 Posted February 18, 2016 Also, the radar warning receivers on all planes have dead zones where wingtips and such block sensors, and the Russian aircraft in particular are bad this way, so it's entirely possible that you get literally no warning that something is guiding a missile at you.
Cik Posted February 18, 2016 Posted February 18, 2016 when a missile says it is "radar guided" it means that someone is tracking you with their radar and then the missile tracks that, not that it homes directly on your radar. there are missiles like that, however i do not believe anyone has ever made one for air-to-air combat. they are used in an anti-SAM role fairly often by everyone, though.
cardboard_man Posted February 18, 2016 Posted February 18, 2016 The Russians actually made air to air Anti-radiation missiles. The R-27P and R-27EP although i don't know how common they were/are.
DarkFire Posted February 18, 2016 Posted February 18, 2016 Also, the radar warning receivers on all planes have dead zones where wingtips and such block sensors, and the Russian aircraft in particular are bad this way, so it's entirely possible that you get literally no warning that something is guiding a missile at you. This is very important to remember, particularly if you're just starting out in the Su-27. The SPO-15 RWR system will only detect radar signals that are within ±30° of the plane of your aircraft. Example: youir SPO-15 detects that an enemy Hawk SAM is tracking you. You decide to turn sharply to get out of the weapon engagement zone and in doing so you bank more than 30°. Because the emitting radar is >30° off the plane of your aircraft the SPO-15 will stop telling you that you've been locked up until your bank angle is back within 30° of the ground. It's very easy to believe that because the SPO-15 isn't displaying a lock warning then the radar must have lost lock, when that isn't necessarily true. Another way to think of it: if the vertical angle between your aircraft and the source of a radar signal is more than 30° above you or 30° below you then the SPO-15 won't detect the radar signal at all. @Hydrox: welcome aboard! If you're new to the Su-27 it will likely seem nearly unflyable t first, but the secret to mastering it is nothing other than putting in the time, effort, sweat, frustration and perseverance. Because it doesn't have the same carefree handling that things like the F-15 have it can seem a real handful and takes far, far longer to master. But, when you do eventually master it, it's an absolute pleasure to fly and can do some absolutely amazing things that no other aircraft in DCS (with the arguable exception of the MiG-29) can ever dream of doing.

A definite +1 for Santi's Su-27 guide. The only thing that I take exception to is that the R-27ER is described as slow and sluggish when in fact it's one of the fastest and fastest accelerating missiles in the entire DCS world: I've seen an R-27ER reach over 4,200 Km/h - a speed that no AIM-120 will ever hope to reach.

Sryan Posted February 19, 2016 Posted February 19, 2016 wait what!!! how do you get an R-27 to go that fast being high and fast. Check my F-15C guide
Sweep Posted February 19, 2016 Posted February 19, 2016 4,200km/h is 2,200kts...Not that hard for an AMRAAM at high alt IIRC. The ER has a lower fly out time at high alt though. Lord of Salt

The ER definitely has a speed advantage at high altitude. It's not massive, but it is noticeable. [sIGPIC][/sIGPIC]
Hydrox Posted February 19, 2016 Author Posted February 19, 2016 ER has a huge speed advantage, it can fly past target way much faster.
DarkFire Posted February 19, 2016 Posted February 19, 2016 wait what!!! how do you get an R-27 to go that fast This is purely from memory, but I think I launched an R-27ER against a KC-135 at around 20 Km. I was at around 7,000m and the target was down at around 2,000m. Launch speed was a hair under 1.2M At the point at which the sustainer burned out the speed of the missile as reported by F2 view was I think 4,219 Km/h.
