The M109 Paladin is a self-propelled artillery weapon, first introduced in the early 1960s. It was designed to fire munitions far beyond the range and power of small arms, and it does that job very well. Conventional rounds allow it to blast targets 11 miles away, and rocket-assisted projectiles can hit targets up to 19 miles away.
The U.S. Army is also testing hypervelocity projectiles originally designed for U.S. Navy electromagnetic railguns, that will increase range up to 58 miles.
