Operated by an 8 to 10-man crew, the triple 7 fires 155mm precision and non-precision munitions.
The non-precision guided munitions have a maximum range of 18.6 miles, while the Excalibur precision-guided rounds have a maximum range of 25 miles and are accurate to within 30 feet.
The howitzer can also fire up to five rounds per minute, or two rounds per minute sustained.

It's fired by the lanyard, held below by Sergeant Greiten, who has completed multiple tours in Iraq and Afghanistan.
Operators move the triple 7 up and down — or to the side — with two wheels, one of which can be seen in the lower left hand corner above.
"It's awesome," Specialist Garcia said about firing the triple 7. "Lima's don't really get you wild-up, but when you get to the hotels, it gets your blood going." Lima's are weaker charges, and hotels are stronger charges.
Garcia deployed to Afghanistan in 2017, and said his crew fired about 300 rounds "at known pools of enemy targets."
Sergeant Shaw, who has served in Iraq and Afghanistan, said the only time it's lowered like that is when the enemy is close, which is not a good position to be in, given that the cannon is meant for support.
Shaw said that his crew once took contact when he was in Afghanistan.
"If you're receiving contact on this howitzer, that means all your front lines are not there anymore, or they've been able to flank the infantry," he said.
But he understandably didn't want to go into details about the incident.
