I know many people hate arty, but for the occasion when we play it would be nice if the game would tell us the arty range of the gun we are using.  I have found player lists on the forums but no official stats in game. Tanks.gg has no real stats for range -- they are all the same for arty, which is not correct.  I found that occasionally an arty gun range will be cripplingly low -- such as the high tier gun on the FV304.  There is no way for the player to know that until playing the tank, unless they find an unofficial list.  Wargaming could you please put range in the gun and tank stats?  Thanks

I don't agree with your "everybody hates arty" supposition, but getting the gun ranges listed in the stats would certainly be a nice thing.

The range is roughly proportional to the following:
([shell velocity in m/s]^2) / (150m/s/s)

For example, a gun with a shell velocity of 200m/s would have an approximate range of 200*200/150=267m. A shell velocity of 500 m/s would be 500*500/150=1,667m.

The actual in-game range varies since the gravitational acceleration is different for different artillery guns, and/or the gun cannot be raised to 45 degrees above horizontal, and/or the target is higher or lower than the SPG (for example the lowest and highest parts of the map "Cliff".

 

IRL, it's v^2 / 9.81m/s/s, at least on level ground and ignoring air resistance and ignoring that trajectories aren't parabolas (which approximates Earth as flat with parallel gravity everywhere) but instead are ellipsis with the center of the Earth as one of the foci AKA an orbit that is mostly underground but would be followed if the Earth were a small black hole with the mass of Earth. Side note, a black hole with the mass of Earth would have a diameter of about 17.7mm, or 0.7 inches. Fun fact, there's a black hole in our galaxy, Sagittarius A*, with a mass of about 5,000,000,000,000,000,000,000,000,000,000,000,000 kg and a diameter of about 5 million miles (the Earth is nearly 100 million miles from the Sun).

Point taken -- I corrected that.

For example, a gun with a shell velocity of 200m/s would have an approximate range of 200*200/100=400m.

The actual range varies since the gravitational acceleration is different for different artillery guns, and/or the gun cannot be raised to 45 degrees above horizontal, and/or the target is higher or lower than the SPG (for example the lowest and highest parts of the map "Cliff".


Thanks for the info. This sounds like real world information from engineering school or the Army?  It is helpful and interesting to know.  But for those of us who got a C in Gunnery class, the game giving us an approximate average range, or "range of range," would still be helpful.  :)  Thanks again.

I edited my post a bit. In-game the shell gravity varies somewhere between 100m/s/s and 200m/s/s, but you can approximate 150m/s/s.

I once again edited my earlier post.
