Russia has begun using a new cruise missile to attack Ukraine, known as the "Filin" cruise missile. This new ground-launched missile has a maximum speed of up to 800 km/h, a maximum altitude of 6 km, and a flight range of 600-1200 km. It is 3.5 metres in length and has a wingspan of 3 metres. It's warhead weighs either 50 or 100 kg, and can be equipped with fragmentation-high-explosive, penetrating, and thermobaric warheads. This was likely that missile that was mixed up with Geran-5 jet-drones on October 16, that I reported as flying at speeds of 700-800 km/h towards western Ukraine.
