André Posted May 1, 2001 Share Posted May 1, 2001 I remembered seeing a video from the -45 Berlin battle featuring a huge gun mounted on a tractor. After searching the internet I found out it was the "203mm Soviet Howitzer B-4" I had seen. Does anyone have any more info on this one? Here is a picture: It was indeed used in Berlin, but I want more info. Regards, Heinz Link to comment Share on other sites More sharing options...

offtaskagain Posted May 1, 2001 Share Posted May 1, 2001 It isn't really mounted on a tractor. Those tracks just give it more stability in the mud. But it can be aimed a little bit by rotating the tracks. It also took 2-3 minutes to reload if i remember right, and it took 3 men on the ramrod. The russians liked to bust bunkers and pillboxes with them. Link to comment Share on other sites More sharing options...
Stalin's Organ Posted May 1, 2001 Share Posted May 1, 2001 There were 6 versions - the first 3 were apparently not used by the Germans, but had German reporting designations H503®, H503/1®, H503/2®. These 3 had an L22 barrel, the last 3 versions had L25. All used the same ammo except the H503®, which used a slightly lighter shell (98kg vs 100kg for the others). Weight in action of the first 3 was 15,796 kg(H503®) or 15800 for the other 2, with maximum ranges of 12800 and 16000m respectively. Link to comment Share on other sites More sharing options...
