F-22 More Revolutionary than I thought! Apparently it has no Avionics at all!

SUBMAN1 · 06-30-09, 08:50 AM

The aircraft, being one giant sensor, needs nothing. This is like Star Trek or something! There are no boxes to remove from this aircraft. No nothing. Need a UHF or VHF radio? Write a software app and presto! You have one! Need a Direct TV connection so you can catch up on your latest episode of Battlestar Galactica while in route to your next target? Write a software app and Presto! You have one! I wonder if it can bypass the encryption mechanism?

Read the interview with Metz (Chief Lockheed test pilot):

That is one very interesting article.

Is this an F-22 or an I-Phone?

The pilot does not care nor does he need to know how the avionics conclude that there is a MiG-29 at 330� at 38.2 miles doing 0.85 Mach number at 30,000 feet. The MiG is real. It is there and he needs to do something about it.

Honestly, statements like this worry me. I sure would like to know, time allowing, how the computer came to this conclusion! After all, it'll be ME that will be explaining things if I hit an airliner or something, not the computer.

Want to bring down a F22? Write a software app and Presto!

LOL just what I was thinking.

Arent these going to fall under the budget axe anyhow?

Gates said we're not going to get any more of them, although we're obviously keeping the ones we have.

Some folks in Congress are trying to get some more built as pork barrel spending for their districts.

Stupid that they are. The F-35, though the second most capable aircraft in the world now, is not going to have the same length of life the F-22 will have. Its just a second rate frame comparatively.

You could build a virus for any platform these days. Problem is, you'd have to have intimate knowledge of F-22 programming. Not likely to happen ever.

Hopefully our pilots are smart enough to not open any emails from the Bank of Nigeria while on a mission.

One word - AESA. THe F-22's version is similar to the Aegis system and it has such a fine resolution, it can identify a target by its shape. It also has such a narrow beam capability that it is unlikely to be detected. It is actually a system of about 50 radars that individually send out weak signals that are thrown out as interference by an RWR on an enemy aircraft, but collect it as one picture.

Couple this with the myriad of other sensors for identification.

Do you have a reliable source for that?

Any AESA page can give you a good run down on it, though the F-22's is a more advanced version of AESA with probably a 250+ (large target) nmi range. With AESA, you even have built in jamming and hacking tools. You can theoretically overload a missile sites computer systems with it. Kind of like a power surge.

Maybe it is not 50, but 1000:

Quote:

The F-22's Northrop Grumman/Texas Instruments-built AN/APG-77 radar is an active-element, electronically scanned (that is, it does not move) array of over 1000 finger-sized transmitter / receiver modules. Each module weights ca 15g and has a power output of over 4W. The APG-77 is capable of changing the direction, power and shape of the radar beam very rapidly, so it can acquire target data, and in the meantime minimizing the chance that the radar signal is detected or tracked.
