Russia is developing hypersonic missiles in response to steps by the US and NATO that broke military parity with Moscow, a senior Russian official said on Tuesday.
These steps include the decision to leave the Anti-Ballistic Missile Treaty (ABM Treaty), signed between the US and USSR in 1972, and the deployment of ballistic missile infrastructure in Europe close to Russian borders, said Kremlin spokesman Dmitry Peskov.
Over the past decades, Russia witnessed gradual destruction of the treaties that form the basis of international arms control, Peskov said at a press briefing in Moscow.
"We also faced certain steps on the part of the US and NATO, which actually damaged the existing parity, including the establishment of missile defense positional areas, the deployment of anti-missile launch systems in Romania and other countries in close proximity to our borders. This is the infrastructure that can also be used to launch attack missiles," Peskov said.
Such a situation demands measures that can ensure Russia's security and would guarantee the continuation of the parity that had been established, Peskov added.
The Russian Defense Ministry announced on Monday that it successfully test-launched a Tsirkon hypersonic missile at a ground target 350 kilometers (217.5 miles) away at Mach 7, or seven times the speed of sound.
Commenting on the tests, Pentagon spokesman John Kirby had said Russia's new hypersonic missiles "could potentially lead to destabilization and pose a significant risk because they can carry a nuclear charge."
