Private Superforecasting Workshop asks:
Will Russia conduct a flight test of an RS-28 Sarmat ICBM before 1 August 2021?
Russia has been developing a new intercontinental ballistic missile (ICBM), the RS-28 Sarmat, for years (TASS, Daily Mail). Russia reportedly planned for five flight tests in 2020, but none were conducted (CSIS). Whether the flight test is deemed successful is immaterial.
The question closed "No" with a closing date of 1 August 2021.
