(Express) – Fears of devastating global conflict have increased following reports Russia is looking to more than double the range of nuke carrying missiles, which could then reach US mainland. The 3M-54 Kalibr cruise missile can transport a nuclear or convention warhead up to 2,000 kilometers. However, it is believed Russia is looking to boost the range to over 4,500 kilometers. Kalibr missiles can be fired from either submarines or surface ships.

A military source told the state-linked Tass Russian News Agency: “The newest high-precision ship-based Kalibr-M cruise missile with a maximum firing range of more than 4,500km was being developed for the Russian Navy.” The weapon upgrade should be complete by 2027, though some Kalibr-M missiles could be supplied to the Russian navy before this date.
