During the War of 1812, Constitution's battery of guns typically consisted of 30 long 24-pounder (11 kg) cannons, with 15 on each side of the gun deck. Twenty-two more guns were deployed on the spar deck, 11 per side, each a short 32-pounder (15 kg) carronade. Four chase guns were also positioned, two each at the stern and bow.
Constitution’s heavy firepower and strong planking (armor) allowed her to stay in fights and win.
