Answer: Russia
Notes: Russia plans to deploy the RS-28 Sarmat intercontinental ballistic missile, also called "Satan 2," to replace older models. The RS-28 Sarmat is a three-stage, liquid-fueled missile with an 18,000 km range and a 208.1 metric ton launch weight. It measures 35.3 meters in length and 3 meters in diameter, carrying a 10-ton payload. The missile can carry up to 10 heavy nuclear warheads, 16 smaller ones, or hypersonic glide vehicles. It features a short initial boost phase, making it harder for enemy systems to track and intercept.
