The VPAM scale as of 2009 runs from 1 to 14, with 1-5 being soft armor, and 6-14 being hard armor. [1] Tested armor must withstand three hits, spaced 120 mm (4.7 inches) apart, of the designated test threat with no more than 25 mm (0.98 inches) of back-face deformation in order to pass.
A Chinese publication lists 30MnCrNiMo "685" steel as the material used in Chinese rolled armor plates, with a Brinell Hardness of HBW 444-514 (thin) / 429-495 (thick). According to the same publication, older vehicles use a 22SiMn2TiB "616" steel with a hardness of HBS ≤ 219.
In pre-Qin dynasty times, leather armor was made out of rhinoceros. The use of iron plate armor on the Korean peninsula was developed during the Gaya Confederacy of 42 CE - 562 CE. The iron was mined and refined in the area surrounding Gimhae (Gyeongsangnam Province, South Korea). Using both vertical and triangular plate designs, the plate ...
Ceramic armor is armor used by armored vehicles and in personal armor to resist projectile penetration through its high hardness and compressive strength. In its most basic form, it consists of two primary components: A ceramic layer on the outer surface, called the "strike face," backed up by a ductile fiber reinforced plastic composite or metal layer.
Ranger Body Armor (RBA) is a US military-issue ballistic vest that was designed for, and used chiefly by, US Army 75th Ranger Regiment operators ("Rangers") in the 1990s and 2000s. The RBA system has since been replaced by other specialized body armor systems adopted by the United States Special Operations Command (USSOCOM) .
Tankō, worn by foot soldiers, and keikō, worn by horsemen, were both pre-samurai types of early Japanese cuirass constructed from iron plates connected by leather thongs. During the Heian period (794 to 1185), the cuirass evolved into the more familiar style of armour worn by the samurai known as the dō. Japanese armourers started to use ...
Augustan period statue of a Gaulish soldier wearing a Roman lorica hamata. Modern historians believe that mail armor was invented by the Celts. [3] [4] With the idea for this form of mail possibly coming to Rome during conflicts with the Celts in the 3rd century BC, [5] [2] lorica hamata was used by both legionary and auxilia troops. [2]
Traditionally, a warship's armor system was designed both separately from, and after, the design layout. The design and location of various component subsystems (propulsion, steering, fuel storage and management, communications, range-finding, etc.) were laid out and designed in a manner that presented the most efficient and economical utilization of the hull's displacement.
