AIM-120 And Method Of Firing

Thu Jul 19, 2012 3:30 pm

The AIM-120 can be carried and fired in a fair few ways, ranging from rails, from a aircraft body station such as on the F-18, from attachment points on the F-15, direct from a pylon on the Sea Harrier (when carried under the body), or from internal bays on the F-22 and F-35.

The majority of these methods do not require rails - but do the other methods incur a performance penalty in not using rails?

If they do it would be fairly minor. The biggest impact on performance is going to be launch altitude, speed and angle to target.

So why carry rails at all then? Just hang the missiles off the pylons and be done with it...

There has to be a reason!

I'd assume its down to the pylons being universal carriers requiring the rails as interface for the AIM-120. Most of the other methods such as conformal and internal are dedicated to the AIM-120 (or Sparrow before it)

Don't forget the "FOX THREE" radio call for an active radar-guided missile launch.

Got any photos distinguishing rails and pylons?

To me they serve the same purpose.

Rails are generally attached to pylons. A pylon can often carry two (or more) rails. Rails are essentially the adapters off of which you can fire AAM's. I don't know enough about the Sea Harrier to speak on it but I would guess that attached to each attachment point (pylon or body) was some sort of rail or ejector devices (AMRAAM can be launched either way).

This shows a BAE Sea Harrier carrying four Aim-120s, two on pylons underneath the body of the aircraft, and two on rails on the wing stations.

Hope that helps!
