Answer: Russia
Notes: The Oreshnik hypersonic missile, recently tested by Russia, has a range of 3,000-5,500 km and can strike targets in Europe and the western US. Its unique feature is the ability to carry multiple warheads, akin to intercontinental ballistic missiles (ICBMs). President Vladimir Putin indicated that this missile's deployment was a response to Ukraine's use of Western missiles, marking a significant escalation in the ongoing conflict. The missile is designed to be highly accurate and currently lacks effective countermeasures against it.
