Were British triple-turret battlecruiser studies consulting work for an Imperial Russian contract?
Short answerIt is possible, although the apparent Royal Navy context makes a domestic design connection at least as important.
NotesThe question links British studies of triple turrets for successors to the Invincible class with the Russian Izmail or Borodino-class battlecruisers. An attempted Imperial Russian contract is one possible explanation for the design activity. Much of the surrounding evidence, however, appears connected to Royal Navy requirements, leaving a domestic design connection at least as important as export work. Further archival evidence is needed to settle the institutional setting of these studies.
