Improved auto-loader adresses this issue. It does not improve range, which is a function of energy. In fact given round sof the same weight, the Russian round at 1750m/s will fly farther than the 120mm round at 1650 m/s. it might improve effective range, which is why rifled guns used to...

1. He did not prove the Arjuns gun was superior, the info provided did not look very impressive. Not at all superior in terms of raw energy to what the T-90's gun can do with modern ammunition and way behind cutting edge 120mm smooth bore ammunition. At best the Arjun's gun is adequate in that...

Ok, thank you although it does not specify, the long delay seems to indicate that domestic production tanks will be using the 2A46m5. I can see little reason why Russia would impose export ToT controls on a dated soviet era gun.

ppjg, I was not aware there was an issue with Russia providing 2a46m5 guns. Do you have a source please?

I never left the US, but not for lack of trying. I volunteered for ODS, but they didn't need Patton crewmen. I was gettign ready to ship out to Germany and probably Bosnia when I got out to try and save my marriage. I agree the round includes the weight of the sabot which makes figuring actual...

I was a tanker of both Patton and Abrams tanks. Kunal, where is that information from and does it include the weight of the sabot in the weight of the round? 8.6 is very heavy as the DM-63 is 8.35kg with sabot.

Ok, first off I did not say I would pick the T-90 any day, I said I would prefer the 2A46m5 gun over the Arjuns. The Arjun's mobility, 4 man crew, greater elevation depression, german MTU engine etc are not to be discounted. Kunal, source for 6.8kg at 1650m/s please. That works out to...

Not without modern ammo.... the guns you make are obsolete... Why is the ammunition changing? HESH rounds do not work vs modern armor where spacing, spall liners and the use of different materials prevents the spalling effect HESH works on. This leaves 3 options- saboted rounds, HEAT rounds...

According to Fofanov, the orignal batch would have been 2A46M2, however it is likely that any of the kits made post 2005 would be the M5 gun as production switched over. The differences are small, the big improvement for the T-90M is the improved auto-loader. According to open source material-...

All T-90's except perhaps the very earliest have the 2A46M5. Although not much different from the gun used on the original T-64 and T-72 tanks it is made to much better tolerances, has a longer barrel life round over round (same round in an earlier 2A46 gun) and can handle increased pressures...

No Indian T-90 has the Rusian system, India chose a Swedish APS for all of its T-90's bot the Bishima and the T-90M

The Abrams is about 14 tons heavier than the T-90m. American tons are short tons, not metric this throws people off. Also most of the DU is under the turret front in the form of rods that being incredibly dense tend to deform penetrators, and/or induce sheer forces. The Abrams also has an...
