MBT-70 vs Object 277 | Armor Penetration Simulation

Simulation of MBT-70 tank projectile hitting the frontal armor of Object 277 tank

152mm XM578E1 (Heavy Tungsten Alloy penetrator, maraging steel jacket APFSDS) at 1430 m/s

vs

Object 277 turret front armor (~270mm, at ~45 degrees)*

MBT-70 152mm XM150E5 gun muzzle velocity - 1478 m/s. 1430 m/s refers to a distance of approximately 0.5 km.

*The area representing the average turret armor protection (between the weakest area near the mantle and the strongest area at the edge of the turret.

Object 277 is a very obscure tank not many people know about. It was developed as a "conventional" version of the much more famous object 279. The turret was very similar to the 279's turret and it used literally the exact same gun. The M-65 130mm rifled cannon. A beast indeed.

Watching this has given me a desire to see comparisons of multiple tanks shooting at the same target to see the differences in effectiveness/penetration directly. Obviously we can make reasonable inferences from the numbers alone, but seeing a direct comparison 'sticks' better as well as allowing us to see smaller differences.

I was always curious how powerful the 6 inch gun could have been with better dart designs.

[MrChewy]

I think this demonstrates how early apfsds projectiles had relatively poor flat penetration compared to heat rounds of the day.

[urosmarkovic]

270 sloped like that is like 350 to 400mm effective, that's no joke for cold war

[DarkestVampire]

When i read MBT-70 i immediately thought you were gonna model a anti tank missile. But then i remembered that anti tank missiles make your computer catch fire when you want to model them.

Lets make a Kursk 1943 "first encounter of two beasts" simulation: SU-152's 152mm BR-540B vs Panther upper front plate at 1000m

[buscadiamantes]

Hello! Could a simulation of an HSTV-L upper front plate be made? Against the projectile of your choice, I don't have one in mind. Thanks!

[samspeed]

Now this should be... Wait, it didn't go through? Not even half way? Daaamn, that's some strong Stalinium

[glxytoni]

looking at how fast graphics are evolving... maybe in a couple of years we can have such fast computers that we can have games like Warthunder simulate every hit like one can only dream

[Phapchamp]

That is a big hole for that projectile. I also love APFSDS barely moves up or down and instead just deforms because speed of the projectile. Those holes reminds me the meteorite marks on moon.

[Mathosalpha]

What mechanical properties were used for the maraging steel and core? Granted 270mm at 45 is about 382mm LoS.

[kite]

Coming out of a 152, that is disappointing.

[alexthegreat]

I would love to see more simulations showing the 277

[MsciwojzPolska]

Wasn't this gun designed to for chonky HEAT nad Shillelagh missile?

[ned]

They crew actually lived for once, wahey!

[Pablonien]

Could you make an video of an shell that's hits the same part twice, and that doesn't pen in the first time?

[anninias]

Could you do the same thing with the conquerors turret? It’s got some gnarly angles I’d love to see maybe t62 APDS or some other early MBTs apds

[JarateHunter]

Could you do a simulation of an ERA detonating on a plate that's too thin? Like yes it could stop an ATGM or maybe even a KE projectile but maybe the flyer plate facing the armor will penetrate it instead.

[acyde]

Love the 277 in WoT absolute blast to play
