Designations
Up until just after World
War II, each caliber of USN guns was identified by a mark number, its length in
calibers and a modification number, the original modification designation being
"Mod 0". For example, 16"/50 Mark 7 Mod 0 meant a gun
firing 16-inch (40.64 cm) projectiles with a barrel 16 x 50 = 800 inches
(20.320 m) long, was the seventh gun in the 16-inch
(40.64 cm) series and was built to the original design with no modifications. A
few smaller guns built or purchased mainly in the latter part of the 19th
century were known by the weight of their projectiles; the 1-pounder through
6-pounder. Roman numerals were used for many designations until about 1920 when
arabic numerals were
substituted.
Gun Mod numbers generally
indicated changes to the original design for new guns or a change made to a
finished gun. For example, a change in the rifling pattern from the original
design might be designated as Mod 1 and new guns built with this rifling would
be so designated. Mod 0 guns being relined with this new pattern would also
then be designated as Mod 1.
Mountings originally had a
similar designation, being of the form 12" Mark 8 Mod 0 for a
mounting using a 12-inch (30.5 cm) weapon. By 1930, the Mark number mounting
designation had been dropped for weapons larger than 5 inches (12.7 cm) and new
mountings were then known by the ship class they were used on. For example, the
mountings for the 16"/50 (40.64 cm) Mark 7 guns used on the Iowa class
battleships were designated as 16-inch three-gun mountings Iowa class.
Mountings for 5 inch and smaller guns continued to have Mark numbers assigned
to them.
Similar to Britain, shortly after World War II the USN designation system was changed from being based upon the gun classification to being based upon the mounting classification. So, a modern designation such as 5"/54 Mark 45 is really the designation of the gun mount, not the weapon itself. Furthermore, starting with the 5"/54 Mark 42, almost all naval guns are now classified into a single "Mark" series, regardless of their caliber. For example, modern guns such as the 5" Mark 45, the 76 mm Mark 75 and the 57 mm Mark 110 are all in the same numeric Mark series.
