Avimimus Posted September 12, 2020 Author Share Posted September 12, 2020 The M230... is rifled? But the round uses effectively a shaped-charge warhead for enhanced penetration? I'm asking because it was suggested to me that the 45mm depressible TKB-700 developed for the Su-25 had a smoothbore barrel to improve the performance of the shaped-charge warhead.

Avimimus Posted September 12, 2020 Author Share Posted September 12, 2020 Much higher velocity as well. I tried looking into this a while ago, and what I found suggests that the Gsh-30-2 has similar ballistics to the A-10's complimentary can-opener. Yeah... compared to the AH-64, the Mi-24P has: 1.34 times the kinetic energy? 2.25 times the high explosive charge? Compared to the Mi-24P, the A-10 has: 1.09 times the kinetic energy (not including the velocity of the aircraft) 1.2 times the explosive charge The A-10 might be about ~20% more effective (assuming the Russian AP rounds aren't much worse). But it looks much more comparable to the GAU-8 than the M230... Link to comment Share on other sites More sharing options...
AlphaOneSix Posted September 12, 2020 Share Posted September 12, 2020 The M230 is rifled, yes. The warhead is classified as high explosive dual purpose. It has a shaped charge that can defeat light armor (around 50mm if my memory is correct) as well as a fragmentation effect. It’s definitely not as powerful as the GAU-8 or 2A42.

Avimimus Posted September 12, 2020 Author Share Posted September 12, 2020 Ah, okay. It is an interesting design. P.S. I should've said the A-10's gun has "1.09 times the kinetic energy". The A-10 itself could probably have about 436,273,768 joules (rough calculation using max takeoff weight at VMax). Link to comment Share on other sites More sharing options...
Rogue Trooper Posted September 18, 2020 Share Posted September 18, 2020 (edited) The Apache basically has the AK-47 of the 30mm Kannons. It will do very nicely..... the others will just do it better. But those yanks know ballistics, its in their blood, how that Kannon behaves as an off axis defensive weapon maybe really cool. A DCS Apache AH-64A will learn us that.

Kerberos Posted September 21, 2020 Share Posted September 21, 2020 (edited) I did some simple calculatons about the kinetic energy of the two compared guns: I get that the Mi-24 has about 1.57 times the kinetic energy of the apache in each projectile at the muzzle heres the calculation: https://www.wolframalpha.com/input/?i=%280.5+*+0.39+*+940%5E2%29%2F%280.5+*+0.339+*+805%5E2%29 Now if I look at the total energy output per second (factoring in the fire rates) I get that the MI-24p's gun has about 15 times the kinetic energy output of the apache at the high RPM setting https://www.wolframalpha.com/input/?i=%28%280.5+*+0.39+*+940%5E2%29+*+2600%29%2F%28%280.5+*+0.339+*+805%5E2%29*265%29 Thats about 7466KW for the Hind and 485KW for the gun of the apache. Now, those numbers of course in no way reflect the combat effectiveness of the guns. I would argue that the apaches gun is much more effective because it is mounted in a turret with an advanced ballistics computer and FLIR. But still: The Mi-24p has one hell of a gun and if aimed properly it can cause some serious damage Edited September 21, 2020 by Kerberos Link to comment Share on other sites More sharing options...
