The M109A6 Paladin is a further upgrade of the M109 self-propelled howitzer, which was introduced in early 1960s. This M109A6 Paladin self-propelled howitzer entered service with the US Army in 1991. Production ceased in 1999. A total of 950 artillery systems were built for the US Army. Export operators are Israel and Taiwan.

Maximum range of fire is 24 km with standard projectiles and 30 km with rocket-assisted projectiles. Maximum rate of fire is 4 rounds per minute. Sustained rate is one round every three minutes.
