Russia's TASS news agency reports that the delivery of the country's newest cruise missile submarine will take place no earlier than the second half of 2020 instead of within this year as originally planned.
The delay has been attributed to the failure of the auxiliary sub-assemblies and mechanisms of the Project 885 or Yasen-class submarine Kazan to satisfy the defence ministry's testing requirements during recent dockside and builder's trials by Sevmash Shipbuilding.
The submarine will undergo another series of dockside and builder's trials after the correction of the identified technical flaws, a process which by itself could last several months.
