Russia claims their new future body armour will stop a .50 cal
 

Hmmmmmmmm...

Will the Opposition Leader be demonstrating its effectiveness? :hmm:

No, he will be demo-ing it's early teething problems.:E

Wont stop a .50 cal blowing your arm off.

From a US website discussing ‘how a .50 cal kills you’...

With a .50 machine gun it's unlikely to be just one round that hits - depending on the particular weapon the rate of fire is 400 - 1200 rounds per minute.

The laws of physics do not apply in the US as Mr Newton didn't get a visa.

Not according to this gentleman who, despite his obvious ancestry, I believe was American...

So maybe sometime in the future the momentum of the .50 cal going forward will equal the recoil going back towards the shooter. I guess at that point our US cousins will stop shooting .50 BMG from a big rifle.

James Doohan was Canadian. Landed with 3rd Canadian Inf Div on D-Day and I believe he flew too.

momentum same in both directions
 

It always was the same. It's the kinetic energy that kills you.

Imagine a ten pound gun firing a one ounce bullet at 1600 feet per second. It will recoil at ten feet per second. Momentum is 10*10 = 100 foot pounds. That's also true for the bullet 1/16 *1600 = 100 foot pounds.

Kinetic energy of gun is 1/2mv^2 (5*10^2) = 5*100 = 500 foot pounds.

Kinetic energy of bullet is also 1/2mv^2 (1/32 *1600^2) = 1/32 * 2560000 = 80,000 foot pounds. It's 160 times as much.

I don't know the actual values, this is illustrative. The recoil will also include that from the high velocity gas propelling the bullet, but I believe recoil suppression devices vent much of the gas backward - at the cost of making the gun even louder. I have never fired anything bigger than a 12 bore shotgun, and that is loud enough for me!

Maybe it will, maybe it won't....but underestimate the Russians at your peril...as the SU-57, continued space program and the Sputnik vaccine show.

a fifty ball plinking into your armour is going to flick you away like lint, it may not penetrate, but being booted over the next county might not end well.

I'm thinking spalling... your tummy is going to have the wobbles as is every cavity of your body. The Ke is roughly the same as a 300lb mass running into you at 100kmhr, with a pointy stick that is 1/2" across. The bullet may not penetrate the vest, but the vest may penetrate the person wrapped around the bullet. gonna leave a bruise.

the 50 has about 18-20kJ of kinetic energy. per standard

Staying Power.
 

Their Sputnik satellite has gone a bit quiet, lately.

Your energy calc is erronous, 20kJ is 110lbs@100kmh or about 2 large dogs@1100 inches/second . . . probaby knock you over . . .

Armaments suppliers are pretty consistent, offering something that is not necessarily needed or capable of being used/ As long as it gets the Dollars / Rubles / Euros or whatever currency then the end justifies the BS.

I saw a show a while back where they were demonstrating the US Army's 50 cal sniper rifle. It was punching a hole through half inch armor plate at something like 500 yds. I also seem to recall they have an "armor piercing" round for the 50 cal machine gun. Hard to believe they could come up with body armor that could stop that - at least body armor that anyone would be able to wear and still move...
Maybe the Russians are re-defining body armor as a small one person tank :ok:

I thought Boris was a bullet dodger ?

Sure .... it’ll probably just deflect the round .... right up his nose!

Very efficient use of propellent (?) which if ignited in a bowl in front of you would be harmless(?)
