Russia stops sharing missile test info with United States
Information was shared to ensure a test launch not mistaken for an attack
A senior Russian diplomat said Wednesday that Moscow will no longer inform the U.S. about its missile tests, an announcement that came as the Russian military deployed mobile launchers in Siberia in a show of the country's massive nuclear capability amid the fighting in Ukraine.
Russian Deputy Foreign Minister Sergei Ryabkov said in remarks carried by Russian news agencies that Moscow has halted all information exchanges with Washington after previously suspending its participation in the last remaining nuclear arms pact with the U.S.
Along with the data about the current state of the countries' nuclear forces, the parties have also exchanged advance warnings about test launches. Such notices have been an essential element of strategic stability for decades, allowing Russia and the United States to correctly interpret each other's moves and make sure that neither country mistakes a test launch for a missile attack.
The termination of missile test warnings appears to mark yet another attempt by Moscow to discourage the West from ramping up its support for Ukraine. It comes days after Russian President Vladimir Putin announced the deployment of tactical nuclear weapons to Moscow's ally Belarus.
Treaty suspended
Last month, Putin suspended the New START treaty, charging that Russia can't accept U.S. inspections of its nuclear sites under the agreement at a time when Washington and its NATO allies have openly declared Russia's defeat in Ukraine as their goal.
Moscow emphasized that it wasn't withdrawing from the pact altogether and would continue to respect the caps on nuclear weapons the treaty set.
The Russian Foreign Ministry initially said Moscow would keep notifying the U.S. about planned test launches of its ballistic missiles, but Ryabkov's statement reflected an abrupt change of course.
"There will be no notifications at all," Ryabkov said in remarks carried by Russian news agencies when asked if Moscow would also stop issuing notices about planned missile tests. "All notifications, all kinds of notifications, all activities under the treaty will be suspended and will not be conducted, regardless of what position the U.S. may take."
Ryabkov's announcement followed U.S. officials' statement that Moscow and Washington have stopped sharing biannual nuclear weapons data that were envisaged by the New START treaty. Officials at the White House, Pentagon and State Department said the U.S. had offered to continue providing this information to Russia even after Putin suspended its participation in the treaty, but Moscow informed Washington that it would not be sharing its own data.
The New START, which presidents Barack Obama and Dmitry Medvedev signed in 2010, limits each country to no more than 1,550 deployed nuclear warheads and 700 deployed missiles and bombers. The agreement envisages sweeping on-site inspections to verify compliance.
The inspections have been put on hold since 2020 because of the COVID-19 pandemic. Discussions on resuming them were supposed to have taken place in November 2022, but Russia abruptly called them off, citing U.S. support for Ukraine.
Siberian exercises
As part of the Russian drills that began Wednesday, Yars mobile missile launchers will manoeuvre across three regions of Siberia, Russia's Defence Ministry said. The movements will involve measures to conceal the deployment from foreign satellites and other intelligence assets, the ministry said.
The Defence Ministry didn't say how long the drills would last or mention plans for any practice launches. The Yars is a nuclear-tipped intercontinental ballistic missile with a range of about 11,000 kilometres. It forms the backbone of Russia's strategic missile forces.
The Defence Ministry released a video showing massive trucks carrying the missiles driving out from a base to go on patrol. The manoeuvres involve about 300 vehicles and 3,000 troops in eastern Siberia, according to the ministry.
The massive exercise took place days after President Putin announced a plan to deploy tactical nuclear weapons to Belarus, Russia's neighbour and ally.
Tactical nuclear weapons are intended for use on the battlefield and have a relatively short range and a much lower yield compared to the long-range strategic missiles fitted with nuclear warheads that are capable of obliterating whole cities.
Putin's decision to put the tactical weapons in Belarus followed his repeated warnings that Moscow was ready to use "all available means" — a reference to its nuclear arsenal — to fend off attacks on Russian territory.
