Why does the Rheinmetall 120mm gun have a larger bore evacuator than say its eastern 125mm counterparts?
No it's not imposible. HEAT (SC) warhed is limited no by explosive but used (diameter) SC. For late 1990s it was 6-6,5x diamater so 120mm x6-6.5 = 720-780mm RHA in best case. And that value (800mm RHA) max is given for most modern NATO 120mm HEAT rounsd, and it's israeli analoge.Keshav Murali said:CL-20 is 60 times more powerful than RDX.
AFAIK 120 mm HEAT with RDX penetrates around ~250-300 mm. If replaced with CL-20 tandem warhead and Obus-G type ball bearings, penetration could be around ~1200 mm or more. Only thing, mass production will be very costly unless orders of more than 30000 or 40000 are placed. I suppose that one round would require around 3 kg of CL-20. 'Adequate quantity' should be around 2 tonnes. so we can make 670+ warheads now already.
If MoD approves the fielding of this round,
R.I.P - Pakistan tanks.
No, it will not.Given this the penetration value will increase dramatically compare to RDX / HMX types..
No, it will not. I read all avaible in google pdfs about SC, HEAT, cumulative jest and others -including few PHDs works, and there is no option to "increase dramatically".The best avaible now big caliber SC warhed have circa 8-9x diameter perforation.
Maybe im stupid but I can see there only 29%...Penetration performance increased by 40%, not by 15 times nor by 60 times.
Israeli clon of DM-12 whit completly new warhed have achivable 800mm RHA. And this round is now most fresh (on west) tank HEAT -developed for Merakava Mk.III/IV.So a 120 mm shaped charge with CL 20 will penetrate less than 900 mm RHA.
2% sounds to be possible in known now aspectsThis penetration is strongly dependant on standoff: During tests with Compostion A5 (which is up to 99% RDX) penetration increased by only 2% for a in-built standoff of 1 CD.
All RHA plates used in the tests have the same thickness. The shaped charge with CL 20 penetrated 7 plates, the warhead with HMX only 5. 7/4 = 1.4Maybe im stupid but I can see there only 29%...
Rather not in that way:All RHA plates used in the tests have the same thickness. The shaped charge with CL 20 penetrated 7 plates, the warhead with HMX only 5. 7/4 = 1.4
I did look up a bit, but I do not see any conclusive evidence that M1A3 will have rifled gun. @Decklander, could you please provide some references, like @Damian has?And where did you read that it will have rifled gun, and what rifled gun?@Damian, M1A3 will have 120mm rifled gun. So much for your self styled outstanding knowldge of tank guns. remember how we debated it a few months ago?
Do you also remember my quote that Arjun Mk-3 will be a turretless tank with three men crew and much better protected than even Mk-2.
The only 120mm tank guns currently developed in USA, are smoothbore XM360 for lightweight platforms and XM360E1 for heavyweight platforms like MBT's.

Old news, from source: THE M1A3 THE WAY IT SHOULD BEMain Gun improvements. Many years ago Jane's Defence Yearbook compared the Rheinmental smooth bore and Royal Ordinance rifled 120mm guns. It concluded that the rifled gun was the better weapon since it was more versatile. American and German operational experience has confirmed this.
