In late 2022, the Russian Defense Minister Sergey Shoigu claimed that supplies of major weapons in the outgoing year had risen by 30%, while the amount of ammunition for rocket, artillery and aircraft systems increased by 69% to 109%. The Chief of Russian Armed Forces General Staff Valery Gerasimov also claimed that his troops had received more than 3,100 armored, rocket-artillery and other weapons including aviation systems and upgraded gunships. Nuclear weapons As of January 2017, the Federation of American Scientists estimated that Russia has approximately 1,765 deployed strategic warheads, and another 2,700 non-deployed strategic and deployed and non-deployed tactical warheads, plus an additional 2,510 warheads awaiting dismantlement. Russia's Strategic Rocket Forces controls its land-based nuclear warheads, while the Navy controls the submarine based missiles and the Aerospace Forces the air-launched warheads. Russia's nuclear warheads are deployed in four areas: Land-based immobile (silos), like R-36 and its replacement RS-28 Sarmat. Land-based mobile, like RT-2PM2 Topol-M and new RS-24 Yars. Submarine based, like R-29RMU2 Layner and RSM-56 Bulava. Air-launched warheads of the Russian Air Forces' Long Range Aviation Command The military doctrine of Russia sees NATO expansion as one of the threats for the Russian Federation and reserves the right to use nuclear weapons in response to a conventional aggression that can endanger the existence of the state. In keeping with this, the country's nuclear forces received adequate funding throughout the late 1990s. The number of intercontinental ballistic missiles and warheads on active duty has declined over the years, in part in keeping with arms limitation agreements with the U.S. and in part due to insufficient spending on maintenance, but this is balanced by the deployment of new missiles as proof against missile defences. Russia has developed the new RT-2PM2 Topol-M (SS-27) missiles that a Russian general claimed to be able to penetrate any missile defence, including the planned U.S. National Missile Defence. The missile can change course in both air and space to avoid countermeasures. It is designed to be launched from land-based, mobile TEL units. Because of international awareness of the danger that Russian nuclear technology might fall into the hands of terrorists or rogue officers who it was feared might want to use nuclear weapons to threaten or attack other countries, the federal government of the United States and many other countries provided considerable financial assistance to the Russian nuclear forces in the early 1990s.
