The Dreadnought Project:Abbreviations
This page serves as a source for all abbreviations used on Tone's Fighting Ships.
AA
AA, A/A or A.A. is an abbreviation for anti-aircraft, normally notating a weapon adapted or designed for use against aeroplanes.
crh
crh stands for Caliber Radius Head. The pointed head of a projectile is described in terms of its ballistic length and the radius of the curvature of its nose. Larger numbers mean a more streamlined profile. Properly, crh is shown as a dual number such as 3/4crh, with the first number indicating the ballistic length and the second number indicating the radius of the curvature, but it is often abbreviated to a single number such as 4crh.
DGOU
Duplex Gyro Oil Unit.
o/a
o/a, o.a. or oa is an abbreviation for overall, and is used when describing the length of a ship. This term refers to the maximum length of a vessel from the two points on the hull most distant from each other, measured perpendicular to the waterline.
p/p
p/p, p.p., pp or lbp is an abbreviation for length between perpendiculars, and is used when describing the length of a ship. This term refers to the length of a vessel along the waterline from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. This was believed to give a reasonable idea of the ship's carrying capacity, as it excluded the small, often unusable volume contained in her overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally this length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition.
RPC
Remote Power Control.
w/l
w/l, w.l. or wl is an abbreviation for waterline, and is used when describing the length of a ship. This term refers to the length of a vessel along the waterline. In a ship with raked stems, naturally this length changes as the draft of the ship changes, therefore it is measured from a defined loaded condition.
