Originally, it was Charles 2C of France who had more than 360 turrets. 19 18 started production with an output of ten.

1925, British A 1E 1 independence is the origin of multi-turret tanks in a narrow sense, and it was trial-produced.

After A 1E 1, British Vexcor Company also continued to develop, but failed to mass-produce due to cost reasons. Then came the mass-produced multi-turret tanks such as T28 and T35, but they became a swan song.
