Yeah just "open the window" of your supersonic jet while you're spinning around like crazy trying to avoid getting stuck up the ass by a SAM. Good advice.

What always works in the movies is to launch missiles at a rock wall and then fly towards it. Veer right or up or left at the last second and the missiles crash into the wall.
Works for torpedoes too. :thumbsup:

If it's heat-seeking (infrared), about all you can do is flare and try a sudden maneuver. Infrared missiles are extremely deadly, extremely fast, and extremely maneuverable. It's unlikely that any sudden move will do much. However, they have a very short range (unlike that BS in Behind Enemy Lines). Longer range radar-based missiles, though, give you a bit more latitude. The best thing you can do is do a 180 and fly away (if it's launched from long range) or fly normal to the missile so it takes a long time to catch up with you.

They are jettisoned for maneuverability. No way would blowing up fuel tanks create the same IR signature as correctly burning the fuel in a turbine.

Are they that complex? So a heat seeking missile has a computer system which stores profiles of aircraft and compares against incoming images? That must take a pretty serious amount of processing power...

either your friend is an idiot or you are for believing him.

even if it did create enough heat to throw off the missile, how do you open the canopy of a jet thats going several hundred mph?

I don't honestly know, but I wouldn't think it would take that much processing power. It's pretty much just a 2d signal detection problem. I'm sure those missiles cost as much as they do for a reason.

The unique head-seeker also extends the lethality of the missile by aiming it to the target's most vulnerable areas. Most heat seeking missiles tend to home on the hottest spot of the aircraft which is normally the rear exhaust system. In modern combat history, some aircrafts that were hit by a missile in that area, managed to survive the flight until the landing. The Python 5, which acquires a sharp image of the target can home on the most critical areas of the aircraft, such as the cockpit or the central area, and significantly improve the chances for a shot down.

the Python 5 claims this ability, of course its really hard to know what the missiles can and can't do.

There is also a sample picture of what an IR seeker on a missile sees, but I'm sure its a bit higher resolution straight out of the missile.

They're fairly complex. They lock onto temperatures which are common in jet exhaust, and can discriminate against other heat sources. If they built them to just go after the hottest heat source they see, you'd have missiles going after the sun 90% of the time.

I heard that they open the canopy and light a fart with the lighter first. it really confuses teh hell out of the missle.

Its perfectly Possible to dodge a missile. You just need to dodge it so that the proximity detonator wont activate and fill you aircraft with shrapnel.

While missiles out maneuver and out speed Jets, Jets have humans inside them, who are capable of making complex maneuvers.

Just get out of the missiles detection cone, and the missile will lose the lock.

Modern IR missiles are scary good. Text

There's another video of the 9X out there that's better than this one, but I can't find it.

don't remember everything about it, but it showed a little text (and maybe even a diagram) before each shot explaining what it was supposed to demonstrate. There was an off-boresight shot and an amazing shot that ended a Lufbery, a few others.

right, because he made every attempt to let us know he was joking :roll:
of all the tings i've read on this forum, it would not suprise me if he thought it was true.

Yeah, that's what I meant. They discriminate by wavelength. Though like some people are linking the newest seem to actually be able to track a picture of the plane and aim for certain parts.

the ability to vector in on center mass is not all that complex. Usually there is a component of forward motion on the missile that is along the same path as the plane itself, a tail chase. it would not be too difficult for the software to move forward of the tailpipe a certain percentage.

Basically, the pilot has to jerk the stick and try to dodge. Once you dodge once, the missle's pretty much lost you. But the trick is to do that dodge, then make sure another one doesn't get shot at you.

Some missiles are radar guided, rather than heat seeking. Fuel tanks present a large radar signature.

No idea if it would be effective though, that's what chaff is for.

Divert all power to aft shield, flip on your cloaking device, worst case jump to hyperspace. Easy!
