Range 40 Kilometers,

and at that range accurate within 2 meters,

this is as near as you want to get to the ponty end of Excalibur (XM982, M982 and M982A1), it is a 155 mm, Global Positioning System (GPS)-guided, extended range artillery projectile in use as the Army’s next-generation cannon artillery precision munition, and speaking of accuracy have a look at this,

fired from a Howitzer the .39-caliber artillery has a range of 40 kilometres, the .52-caliber artillery can reach up to 50 kilometres, there are plans in the pipeline to increase the range to 70 kilometres, I just hope Excaliburs sat nav is better than the one we have in the car, or it will be traveling along every narrow lane it can find!
