With the 750t destroyer class, 12x750t TGB were built.
TGB750, Byzantine Empire TGB laid down 1906

in 1914 Re Classed as "Destroyer" then renamed D750 class

In 1922, their too low speed made them reclassify in the category of TGB and assigned to the surveillance of the far east colonies.
For their patrols, a long-range radio (25t) was installed in 1922H2.
They are back in TGB topic
