use
The BL 6 Inch Mk XII replaced the earlier 50 caliber ship gun BL 6 Inch Mk XI on many ships of the Royal Navy , as this had proven to be too unwieldy , especially on light cruisers . At the start of the First World War , it was the most advanced British 152 mm gun. It was mainly mounted with individual lubrication. Due to the low elevation range of 40 °, it was not suitable for air defense .
