In 1914H1, all nine of these ships received 1912 Fire Control.

Parisius, Caerleon, and Augustonemetum were sunk in this configuration at the Battle of Ironclad Bay

By the end of 1923H1, the six surviving ships had been updated to 1918 Fire Control.

Who cheer when solider lads march by
Sneak home and pray that you'll never know
The hell where youth and laughter go.
