General description

Achilles displaced 13550 long tons (13,767.5 t) as built and 14500 long tons (14,732.7 t) fully loaded. The ship had an overall length of 505 in 4 in (154.03 m), a beam
Beam (nautical)

The BL 9.2 inch guns Mk IX and Mk X were British 46.7 calibres naval and coast defence guns in service from 1899 to the 1950s. They had possibly the longest, most varied and successful service history of any British heavy ordnance.-History:...

 gun on a high-angle Mark Ic mounting was mounted on the quarterdeck in 1915. It had a maximum depression of 8° and a maximum elevation of 60°. The gun fired a 6 pounds (2.7 kg) shell at a muzzle velocity of 1765 ft/s (538 m/s) at a rate of fire of 20 rounds per minute. They had a maximum ceiling of 10000 ft (3,048 m), but an effective range of only 1200 yards (1,097.3 m). Achilless foremast was converted to a tripod mast to support the weight of a fire-control director after the Battle of Jutland in 1916, but when the director was actually fitted is not known.
