A tank with sufficient armour could resist the largest anti-tank guns then in use. RHA was commonly used during this period (combined with other plate alloys and cast steel armour), and the power of anti-tank guns was measured by the thickness of RHA they could penetrate. This standard test has remained in use despite the modern usage of many ...
Some Sherman tanks were up-armoured in the field with glacis plates and other armour cut from knocked-out tanks to create Improvised Jumbos, named after the heavily armoured M4A3E2 assault tank. In the Vietnam War, U.S. "gun trucks" were armoured with sandbags and locally fabricated steel armour plate. [20]
A similar system using glass inserts in the main steel armour was from the late fifties researched for the Soviet Obiekt 430 prototype of the T-64; [29] this was later developed into the "Combination K" type, having a ceramic compound mixed with the silicon oxide inserts, which offered about 50% better protection against both shaped charge and ...
When a shaped charge strikes the upper plate of the armour, it detonates the inner explosive, releasing blunt damage that the tank can absorb. Reactive armour is intended to counteract anti-tank munitions that work by piercing the armour and then either killing the crew inside, disabling vital mechanical systems, or creating spalling that ...
The M60 was the last U.S. main battle tank to utilize homogeneous steel armor for protection. It was also the last to feature either the M60 machine gun or an escape hatch under the hull. Originally designated the M68, the new vehicle was put into production in 1959, reclassified as the M60, and entered service in 1960.
Non-explosive reactive armour (NxRA), also known as non-energetic reactive armor (NERA), is a type of vehicle armor used by modern main battle tanks and heavy infantry fighting vehicles. NERA advantages over explosive reactive armor (ERA) are its inexpensiveness, multi-hit capability, [ 1 ] and ease of integration onto armored vehicles due to ...
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. It was developed by Germany's Krupp Arms Works in 1893 and quickly replaced Harvey armour as the primary method of protecting naval ships, before itself being supplanted by the improved Krupp ...
Limitations in manufacturing capacity and the added cost led to this armor being dropped by November 1958 [33] and all M60-series tanks were protected with conventional steel armor but the tank retained the capability to employ armor panels. [36] The M60 was the last tank to feature an escape hatch under the hull.
