Erebus-class monitor HMS Terror (I03) guns note smoke generator and high vis tower
Modified Mark I* Turret on HMS Terror in 1915. Note the armor plates covering the gunports under the barrels and the armor cowls under the bloomers above the barrels. These were result of changing the range of elevation from -5 / +20 degrees to +2 / +30 degrees. Also note the smoke generator apparatus on the direct control spotting tower, useful in “shooting and scooting” in the Belgian littoral against German coastal artillery. IWM photograph SP 1612.
