According to AW&ST the SU-30/35 has a 90,000lb GTO weight. That's one big a/c. Also, have others here read anything about Russia's passive infrared equipment that, in addition to providing azimuth info, also provides range info as well? Apparently, (and this is over 1 yr old info) the USAF sent a squadron of their newest F-15C's to India to do DACM with their Mig's. The Mig's, equipped with the super-duper infrared, just waxed the Eagles in almost every engagement. If this is very out-of-date gouge, then I apologize in advance.
