Dear Colleagues, although this subject appeared in numerous discussions and publications, can you explain to a layman how an SNR-125 Low Blow managed to get a lock on an F-117 and to shoot it down on 27 March 1999? Can this kind of radar operating on the I/D band indeed lock on a stealth plane? I can understand that a P-18 Spoon Rest operating on VHF could detect a stealth plane from distance, albeit with mixed accuracy, especially back in 1999, but what about the SNR-125? Or was another detection method used like the LLTV? This site mentioned Serbian modifications and upgrades to the original SNR-125, however it remains unknown if they were applied before the events of 1999. Any comments appreciated.
