The best result was achieved by utilizing a 20 millimetres (0.79 in) thick MEXAS armour panel on top of a 7.3 millimetres (0.29 in) HHA plate fitted with a 10 millimetres (0.39 in) liner on the interior — a mass efficiency of 3.5; however the higher thickness decreased the thickness efficiency to 0.8 compared to the other tested armour layouts.
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.
Lamellar armour was used over a wide range of time periods in Central Asia, Eastern Asia (especially in China, Japan, Korea, Mongolia, and Tibet), Western Asia, and Eastern Europe. The earliest evidence for lamellar armour comes from sculpted artwork of the Neo-Assyrian Empire (911–609 BC ) in the Near East .
Experimental 6 inch (150 mm) Krupp armour plate from 1898. Krupp armour was a type of steel naval armour used in the construction of capital ships starting shortly before the end of the nineteenth century.
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.
Advanced Modular Armor Protection (AMAP) is modular composite armour concept, developed by the German company IBD Deisenroth Engineering, since 2019 part of Rheinmetall Protection Systems. According to IBD AMAP is a 4th generation composite armour, making use of nano-ceramics and modern steel alloy technologies. [ 1 ]
Antibiotic use was not associated with an increased risk of cognitive impairment and dementia in healthy older adults, according to a recent study.
The Soviet T-64 was the first mass-produced tank with composite armour The Leclerc tank is equipped with NERA (Non-explosive reactive armour) [1] Depending on the operating state, the Leopard 2 has various extended armour elements such as bomb protection for the top, cage armour, extended mine protection (A6M) or additional armour in the form of composite armour MEXAS or AMAP Plasan SandCat ...
