How many inches of homogeneous armour is equal to an inch of depleted uranium/chobham armour(In terms of resistance towards HEAT rounds). I am wondering this because Ive read that a PG-7VR (rpg tandem) warhead can pentrate up to 29.5 inches of homogeneous armour and I wan't to know the penetration power when met with newer more resistant armours. Thanks.

You can stop building your backyard bunker. Trump isn't going to nuke CA. :lol:

Got a AR or 1911 question that one of us could possibly answer? Depleted uranium and RPG's specs are just a little out of my league.

Basically, to stop kinetic energy weapons, it really comes down to a few centimeters of very hard plating. To stop Chemical Energy weapons, it is all about spacing and reactive armor (not just ERA, but passive ones like Ceramic composites as well).

High tensile alloy faced armor is an arrangement common amongst state of the art tanks. Basically, it is a thin sheet of tungsten alloy or in the case of late model M1 tanks Depleted Uranium acting as the strike face of whatever the armor type is underneath. The mission of this is to fracture long rod penetrators and render them practically useless. Tungsten-carbide is actually harder than DU, but DU is also very hard and is less prone to shattering making it a superior material for penetrators and strike faces. The problem is DU dust is toxic and is very unhealthy if breathed in.

The current armor package for the M1A2 for example uses Depleted Uranium strike faces, an advanced Chobham type ceramic laminate, baffled spacing and Kevlar type supplementary backing for critical spaces. The exact thickness and construct of the laminated armor blocks are of course highly classified. I believe the core armor for the up armored Leopard 2s remain the same as the original Leopard 2’s perforated type. However, the big chunks of additional armor probably has high tensile strike faces and are probably mostly hollow – if they were not largely hollow, the Leopard 2A6 would be a lot more than 70 tons. Only the Chinese military officials will know the exact composition of the armor on the Type 98 and 99 tanks. However, if I have to take a guess I say they are using perforated armor with hardened strike faces and ERA. This will be consistent with the need for squared profiles and the modest weight of the packge.

The PG-7VR projectile is a Russian-made tandem charge HEAT round developed by the state-owned enterprise Bazalt in 1988, and designed to defeat Explosive Reactive Armour (ERA). A 64mm shaped charge is carried forward of the main shaped charge, separated by an extension boom. This charge is intended to detonate the ERA of the target vehicle, allowing the primary 105mm charge to penetrate the regular armour. It weighs in at approximately 4.5kg, has an operational range of around 200m, and is supposedly capable of penetrating up to 600mm of Rolled Homogenous Armour (RHA) after detonation of ERA by the forward charge. The primary explosive is 1.43kg of OKFOL (окфол), an HMX-based compound.

None of that will matter a few years from now as tank-mounted hyper-velocity rail guns and powerful new lasers being developed now - practically sci-fi class 'phasers' - enter service on tanks, ships, and as miniaturization progresses, even aircraft. Expect in about ten years (unless Democrats win in 2018 or 2020) to see the deployment of orbital battle stations (Raytheon and Boeing have had the plans for years) armed with nuclear-pumped lasers with variable emitters capable of destroying anything from a small high value target, to large military and naval formations, to airborne squadrons of bombers or fighters, to large areas of big cities.

With the election of a patriotic president and congress, America's "skunkworks" will all be working overtime to help Make America Great Again.

Sorry!! If you dont know how to fire 1911 pistols you can take some PG-7VR s to the range only.

I would love to shoot one of those but unfortunately there is a whole long list of people and organizations that would frown upon it.

Protecting future tanks

Combat vehicle Tank Military vehicle Vehicle Self-propelled artillery

A bendable titanium alloy suspension system inspired by the hard shells and flexible legs of ironclad beetles could hold the key to protecting future military vehicles from explosive impacts.

BAE is building a military tank that can withstand explosions by bouncing back into shape after impact, so that the vehicle can continue its mission.

The firm is using a bendable titanium alloy suspension system, made from the same type of material used in flexible glasses, which enables the vehicle’s suspension to return to its normal form after impact, according to the company’s statement.


It is evaluated that the new system could be made available in the next decade. Initial tests of a prototype have already succeeded.

According to defenseworld.net, currently, the hulls of combat vehicles and their passengers are protected from blasts such as mines or IEDs, but key operational parts such as the vehicle’s suspension can still be damaged, meaning they must be rescued by other military units.

Marcus Potter, Head of Mobility at BAE Systems Land (UK) said, “This use of memory metals could prove a real game-changer for combat vehicles taking part in operations.”

Being able to adapt to changing situations is hugely important to maintaining effectiveness, and this application of bendable titanium could give armed forces the required flexibility and survivability to complete tasks in challenging areas, he added.

According to BAE Systems engineers, this is the first time the metal alloy has been used to build an entire suspension system. Using memory metal also means the spring can be removed entirely from the suspension strengthening and simplifying the system further.

A prototype of the suspension system has already been constructed and tested by a team of experts and apprentices at BAE Systems as part of their response to a competition placed by the Government’s Defence, Science and Technology Laboratory for an unmanned tank

The small-scale prototype underwent five increasingly powerful explosive tests, showing significant resilience against the blasts as a result of its highly robust construction.

The company’s engineers are investigating adapting memory metal suspension for full-size combat vehicles.

I heard of 'memory metals' maybe 20 years ago, and prices were outrageous for any application. Cool thing about the military (or NASA) is they can develop the tech to the point where civilian applications are priced more moderately. Really enjoy hearing news like this.
