F-35 simulator article

2007 article on F-35 simulator mission:
http://www.flightglobal.com/articles/2007/07/31/215810/flight-test-f-35-simulator-virtual-fighter.html

Not sure where I got this from but:
16 m + 5.5 m ramp x 4 x 4 m

PAK-FA is a 5.5 generation fighter

Why?

It’s over:

R-27AE never entered service. Alamo E is R-27P.

Its only a ‘fully passive intercept’ if the target isn’t fitted with missile approach warning sensors (MAWS).

The ICMS Mk3 EW suite on Greek Mirage 2000-5EGM is credited with the ability to detect and jam AAM/SAM midcourse datalinks. Same ability is credited to IMEWS on UAE Mirage 2000-9.

SPECTRA covered 2-18 GHz (F1) improved to 2-40 GHz (F2).

Praetorian is said to be 100 MHz to 10 GHz (possibly up to 18 GHz) and can detect almost any radar, some radios and AAM midcourse datalinks.

So if Mica IR/EM (or AMRAAM or R-77) is using the midcourse link, modern fighters will detect the link.

TARH missiles such as AMRAAM do not switch the seeker on to very close to the target. Rumours suggest the AMRAAM seeker active switch on range was reduced during early testing to avoid giving the target too much warning.

I read in one of the artice today that F-22 internal weapon bay cannot be used at supersonic speed and that F-22 needs to turn to subsonic to release weapons from internal bay , is this true ?

Initially it was limited to subsonic JDAM drops (2005), which were later cleared for supersonic drops (2007).

Were did you read the article?
