President Dudayev was killed on April 21 1996, by two laser-guided missiles when he was using a satellite phone, after his location was detected by a Russian reconnaissance aircraft, which intercepted his phone call. Despite America’s ban on assassinations, it is suspected the NSA was involved in the assassination by providing one of their SIGINT satellites to assist in the triangulation.[3] At the time Dudayev was reportedly talking to a liberal deputy of the Duma in Moscow, reportedly Konstantin Borovoy. Additional aircraft were dispatched (a Su-24MR and a Su-25) to locate Dudayev and fire a guided missile. Exact details of this operation were never released by the Russian government. However, it is known that Russian reconnaissance planes in the area had been monitoring satellite communications for quite some time trying to match Dudayev’s voice signature to the existing samples of his speech. It was a grave mistake on Dudayev’s part to use a satellite phone, especially with his experience as a Soviet Air Force general.
