 A number of plans were made for the post @-@ war completion of the ships , including modifying the turrets to load at a fixed angle of + 4 ° to reduce the weight and complexity of the loading equipment . Another intended change was to lengthen the funnels by 2 metres ( 6 ft 7 in ) to minimise smoke interference with the bridge , as this had been noted as a problem on the Gangut @-@ class dreadnoughts . There were suggestions to improve the machinery with geared turbines , turbo @-@ electric drive , or Föttinger 's hydraulic transmission , but these were more theoretical than practical .
