This retains the automatic loading system which allows it to fire three rounds in less than 10 seconds, or six rounds a minute for three minutes (the sustained rate of fire
being two rounds a minute), but all actuators are electric.
Once the SBF has achieved the fire superiority, it is common to return to a sustained rate of fire
on the objective.
The PIM includes a sustained rate of fire
of one round-per-minute and a maximum rate of fire of 4 rpm, said Ed Murray, Department of the Army Systems Coordinator--Artillery.
Moreover the Dana was equipped with an autoloader which rammed round and cartridge at any elevation of the gun, something unique at that time, and thereby provided a high sustained rate of fire
of three rounds per minute for 30 minutes.
A 60mm mortar section can fire 350 rounds in approximately 9 to 10 minutes at a sustained rate of fire
A trained crew can achieve a burst rate of 16 rounds in the first minute followed by a typical sustained rate of fire
of four rounds/min.
