On 1 November Vladimir Putin's forces 'conducted an unsuccessful test of the RS-24 Yars intercontinental ballistic missile, which is the main element of the ground-based component of the Russian strategic nuclear forces'.
The missile 'went off course, as it did during the previous command and control exercises' on 25 October, says the Ukrainian defence ministry's main intelligence directorate.
'Similarly, the test launch of the RSM-56 Bulava ballistic missile from a….missile submarine on 25 October 2023 was unsuccessful, once again proving its insecurity.'
