America, Russia, and China are all working on advancing and upgrading their nuclear weapons. Key point: The specifics of nuclear weapons is one of the more closely-guarded secrets of any country. Just how fast or unique might Russia's new system be? The first crop of details has emerged concerning the mysterious new Kedr intercontinental ballistic missile (ICBM), the successor to Russia’s current Yars missile system. Russian state news outlet TASS reported earlier this month that work will soon commence on Russia’s next-generation intercontinental ballistic missile (ICBM). “Research work on Kedr has been financed under the current state arms procurement program, which is in effect until 2027. Technological development will begin in 2023–2024,” a defense industry insider source told TASS.
