Russia is in the process of equipping its new nuclear submarines with hypersonic Zircon missiles, the head of Russia’s largest shipbuilder has said. “Multi-purpose nuclear submarines of the Yasen-M project will... be equipped with the Zircon missile system on a regular basis,” Alexei Rakhmanov, chief executive officer of the United Shipbuilding Corporation, told RIA. “Work in this direction is already underway.” Yasen-class submarines, also known as Project 885M, are nuclear-powered cruise missile submarines built to replace Soviet-era nuclear attack submarines as part of a programme to modernise the Russian navy’s fleet. Sea-based Zircon hypersonic missiles have a range of 560 miles and can travel at several times the speed of sound, making them extremely difficult to defend against them. What are hypersonic missiles? Hypersonic missiles, like the Zircons or the Kinzhal (”Dagger”) rockets the Russian Air Force has allegedly already deployed in its war in Ukraine, are thought to represent the next generation of arms. The Kinzhals can travel at exceptionally high velocities – up to ten times the speed of sound, which is around 8,000mph. By comparison, a subsonic cruise missile like the US Air Force’s Tomahawk rocket moves at a relatively sluggish 550mph. Kinzhals are typically carried by MiG-31K fighter jets and can hit targets as far away as 1,250 miles, their speed, mid-flight manoeuvrability and ability to fly at low altitudes making them difficult to track using radar on the ground and therefore near-impossible to stop. Perhaps most alarmingly, the Kinzhal can carry a nuclear warhead as well as a conventional explosive, a strategy it has been feared Russia could resort to as its war becomes ever-more desperate and drawn-out than expected due to the heroic resistance put up by the locals, well armed by their international allies. Which countries have them? Australia, the UK and US, together known as the Aukus nations, previously announced a plan to expand their military pact to collaborate on the development of hypersonic missiles and anti-hypersonic weapons. In April 2022, the then-prime ministers of Australia and Britain, Scott Morrison and Boris Johnson, joined Joe Biden in issuing a joint statement saying their countries would “commence new trilateral cooperation on hypersonics and counter-hypersonics, and electronic warfare capabilities, as well as to expand information sharing and to deepen co-operation on defence innovation”. “These initiatives will add to our existing efforts to deepen cooperation on cyber capabilities, artificial intelligence, quantum technologies, and additional undersea capabilities.” The Aukus deal was initially signed to concentrate on nuclear submarine development with a wary eye on potential Chinese aggression in the Pacific, but focus has now shifted towards the threat posed by Vladimir Putin. Russia’s defence ministry has already said its forces have fired hypersonic ballistic missiles in the conflict, claiming to have destroyed a fuel depot in the Black Sea city of Mykolaiv and an underground ammunition store in western Ivano-Frankivsk. How effective are they? Military analyst Pavel Felgenhauer has argued that the use of such weapons will make little difference on the ground and that their true value is “giving a certain psychological and propaganda effect”. In other words, inspiring terror. Mr Putin has boasted of Russia’s investment in such “invincible” weaponry, justifying doing so as a response to what he considers to be Nato military expansion on his country’s doorstep in Eastern Europe. The US and China are said to be working on their own versions, as are the navies of Britain and France, who are understood to have been collaborating on one known as Perseus since 2011, although it is not expected to enter service for another seven years or so. What’s happening in the US? Andrew Hunter, assistant secretary of the US Air Force’s acquisition team, told politicians in March this year that his team would not go ahead with purchasing the hypersonic AGM-183A Air-launched Rapid Response Weapon after the prototyping phase ended. There were problems with the weapons during testing. Mr Hunter, in written testimony, told the House Tactical Air and Land Forces Subcommittee the service planned to finish the ARRW programme’s last two all-up round test flights to collect data that might help with future hypersonic programmes.
