The INF Treaty, signed by the United States and the Soviet Union in 1987, bans all ground-launched ballistic missiles with ranges between 310 and 3,400 miles (between 499 and 5,471 kilometres). The United States has repeatedly claimed that the range of Russia's 9M729 missile violated treaty limits, with Moscow responding by vehemently denying the allegations, citing a lack of proof.
Moreover, Russia also complained that US defence systems in Europe are equipped with launchers capable of firing cruise missiles at intermediate ranges.
