Russia’s New Super Quiet Ballistic Missile Sub In “Final” Sea Trials After Years Of Delays

War Zone – The Russian Navy’s newest ballistic missile submarine, the Project 955A Borei-A class Knyaz Vladimir, has headed out for its “final” sea trials, indicating that it could finally enter service in the near future. The boat was originally set to formally join Russia’s Northern Fleet back in 2017, but that schedule repeatedly slipped due to technical issues.
