1) The propellant charge for the single Mark V gun carried by HMS Erin was 288 lbs. (130.6 kg) in order to obtain the same muzzle velocity as the Mark VI guns.
2) The projectile lengths given are average numbers. There were as many as five different manufacturers for these munitions, each producing a slightly different projectile from the others.
|Elevation||With 1,400 lbs. (635 kg) AP Shell|
|Range @ 20 degrees||23,110 yards (21,130 m)|
|0 yards (0 m)||
|10,000 yards (9,144 m)||
1) Data from "British Battleships of World War Two."
2) The penetration figures in this table are for an uncapped AP shell striking the plate at 90 degrees, i.e., with the axis of the shell perpendicular to the face of the plate. A capped shell would give about 10 to 20% improvement at low velocities and about 30 to 50% at high velocities.

|Weight||600 tons (610 mt)|
|Elevation||-3 / +20 degrees|
|Rate of Elevation||N/A|
|Forward and aft turrets: about -150
/ +150 degrees
Q turret: about 30 to 150 degrees on either side
|Rate of Train||N/A|
|Note: Superfiring turrets could not fire within 30 degrees of the axis because the blast effects would have penetrated into the lower turrets through the sighting hoods.|
