Test launch from an underwater firing position is awaited. The Russian military has yet to comment on the report's veracity.

The Zircon was launched in January by Admiral Gorshkov in the Barents Sea, home to the Northern Fleet of Russia. 

Russian President Vladimir Putin disclosed in December that it was developing a ground-based version of the Zircon.

It is estimated that the Zircon has a flight range of more than 1,000 km and is intended to be mounted on both surface ships and submarines, including vessels designed to carry existing cruise missiles of the Kalibr class. It is also commonly anticipated that the missile will be installed on board the latest nuclear submarine of the fifth generation Husky class currently under construction.

The Zircon's testing began in 2015, with almost a dozen launches completed by 2018. In his speech to Russia's Federal Assembly in 2018, President Putin described the Zircon as one of half a dozen strategic systems capable of evading US missile defenses, thus ensuring a Russian response capability.
