F/a 22 Rcs

urmomma158 · 04-29-2006, 21:14 PM

i know its exact RCs but i would like to know if it changes slightly or dramatically based on wavelength. Its designed for All aspect wideband stealth for a wide spectrum of frequencies like the B-2. So can anyone shed light on this.

It's just plain F-22A.

The F/A- designation was dropped many moons ago.

The F-22 has the RCS of a fly. If any radar could detect the F-22, it would have to detect every fly in the area.

BTW, as Sniper said, the F/A-22 designation was removed back in December 2005. It's been months since then. Now it's F-22A.

Gentelemen. Your knowledge of the most classified US fighter is really funny.

First it was a basket ball, then golf ball. Last time it was a bee.... now Raptror's RSC is downgraded to a fly!!! is it a steel coated fly or just regular fly?

You are confused, Garry.

F/A-18E/F = basketball
F-35 = golf ball
B-2 = bee
F-22 = fly

You're RCS ratings for the Raptor are actually those for the SuperHornet, JSF and B-2 Spirit.

OK. Stand corrected

Lets add there Flanker = a big crowd of bees sitting on a basketball

Well a guy I know compiled a list of RCS of a bunch of aircrafts and then posted them up, including the F-22. Note he said that they are based on rough estimates by a variaty of sources, so you should not take this as actually the real thing. It is just for the ballpark guessing:

Raptor: 0.0002m2

I remember highsea and jgetty were discussing this issue with lurker..... RSC is quite different from various angles and to various bands. Plus it would vary with different positions of Raptor's own radar antena (highsea assumed that it can fold up in a passive mode).

anyway. Averaging down few speculations do not necceserity give result close to actual data.

True however most sources state this is the actual RCs. Not to mention most people forget that the F/A 22 is all aspect wideband stealth.

* Radar signature approximately the size of a bumblebee, thereby avoiding detection by the most sophisticated enemy air defense systems
* Signatures/emissions of sound, turbulence, and heat that can aid detection are reduced
* Requires no direct assistance from electronic support aircraft that may be more easily detected
* Includes planform alignment of the wing and tail edges, radar-absorbing sawtoothed surfaces, an engine face that is concealed by a serpentine inlet duct, "stealthy" coating cockpit design to minimize the usually substantial radar return of pilot’s helmet
* Through internal weapons placement, the F-22 eliminates multiple surface features that could be detected by enemy radar

Its wideband stealth should allow it to maintain it for a wide range of frequencies at least in the X band targeting band and higher. UHF,VHF,HF, will be larger

The F-35 Joint Strike Fighter was a first step in the stealth reformation. Planners are considering abandoning the radar blocker in the exhaust with the idea that the 5-deg. cone of vulnerability out the aircraft's tail was an acceptable risk given the altitude at which it would fly (a margin of safety provided by the use of precision weapons). Its overall radar signature, for example, is about -30 dBsm. (the radar reflection of a golf ball) in most directions compared with -40 dBsm. (a marble) for the F/A-22. (AW&ST Aug. 27, 2001, p. 34).

i can give more sources concerining wideband stealth if you want guys.

Yeah I forgot to add that is frontal aspect. Indeed, the RCS changes from the position you are looking at an aircraft.

Also like I said, this gives a general ballpark not the accurate thing. A good starting point, if you ask me.

Wellduh so what do you think of my previous post.

Garry, you misunderstood my post.

I will try to find a pic so it's more clear.

No, more precisely......a "hornet"

Here you go, Garry. This is a pic of the APG-79, but the -77 front array is oriented the same way. The array is fixed, so it doesn't "fold up" when passive. What I was saying is that it is angled upwards, which redirects backscatter from the antenna away from the emitter and up into the sky.

So to get a return from the antenna, the emitter has to be in front of, and above the AC. This is not really a safe place to be if you're hunting Raptors!
