In response to questions from reporters at a news conference in the Kremlin on Sept. 1, 2021, President Vladimir Putin said the new Russian missile was called the Hazel Tree because the weapon's design was inspired by a Soviet-era experiment.

According to Putin, the experiment was conducted in the 1940s, when Soviet scientists were working on a missile called the Tsarevich. The research failed, but the scientists learned from the failure and applied some of its key elements to the later Hazel missile.

Inspired by a failed Soviet-era research project, Mr. Putin explained, the Hazel represents a spirit of innovation and breakthrough. The missile is powerful and precise enough to strike enemy targets at long distances.

In addition, Putin also stressed that Russia's new missile is one of the largest long-range ballistic missiles in the world, with a range of more than 3,000 kilometers and can cover most of the world. Its appearance means that Russia has mastered advanced long-range attack capabilities and is ready for future wars.

Overall, Putin spoke highly of Russia's new missiles, which he considered an important part of Russia's defense capabilities. He hoped that other countries would respect Russia's sovereignty and territorial integrity and not try to interfere in Russia's internal affairs.
