How much of Constitution is original?

The Naval History and Heritage Command Detachment Boston, the unit charged with overseeing Constitution’s maintenance and repair, estimates that 10 to 15 percent of the ship’s fabric is composed of timber installed between 1795 and 1797. This “original” wood includes the ship’s keel, lower futtocks, and the deadwood at the stem and stern.

How can I find out more about life at sea on Constitution?

The best and most exciting way to discover what life was like on board USS Constitution is to visit the Museum’s new exhibit “All Hands on Deck: A Sailor’s Life in 1812.”

For suggested reading on the topic, please see the Bibliography.

How many guns (and what types) does Constitution carry?

Originally rated as a 44-gun frigate, Constitution typically carried around 54 cannon. During the War of 1812, she mounted thirty 24-pdr long guns on the gundeck and twenty-four 32-pdr carronades on the spar deck, as well as a long 18-pdr “chase” gun forward. In 1814, Capt. Charles Stewart removed four carronades and replaced them with two 24-pdr Congreve “shifting gunades.” She also carried a 12-pdr brass carronade for the launch.

Today all of Constitution’s guns are replicas. All but two of the guns on board were cast in the 1920s and 30s. Two carronades aft on the spar deck were cast in 1983, based on a drawing of the weapons used during the War of 1812. Founder Henry Foxall cast the carronades in 1808, and these were on board when she was recommissioned in 1809. The Navy removed them after the Ship’s World Cruise in the 1840s. The incised “broad arrow” on some of the 24-pounders is a British mark, signifying that the gun was originally property of the (British) Crown. The other mark is called the “royal cipher:” GR for Georgius Rex (King George III). These replicas were cast about 1930, and the cipher/board arrow marks were based on bad information – Constitution’s guns did not carry these marks.

Between 1807 and 1808, Maryland’s Cecil Iron Works cast all of the 24-pounder guns used on board during the War of 1812. Most of them remained until the late 1840s. Constitution’s original (1797) battery was to have been supplied by Hope Furnace in Rhode Island. After running into some casting and boring problems, however, the contractor could not fill the contract by the time the ship was ready to sail in 1798. To complete her battery, the Commonwealth of Massachusetts loaned the Navy 16 18-pound long guns from Fort Independence. These guns might have had the broad arrow, but again, these guns were gone by the War of 1812.

Constitution’s 1812 long guns weighed 5554 pounds exclusive of the carriage and required a crew of 14 men to operate them. The carronades weighed 2222 lbs without the carriage and needed a crew of 4 to 8 men.

What did Constitution look like when she was launched in 1797?

The truth is we really don't know exactly how Constitution looked when first she saw service. While the designer's original draught still exists, there is much additional documentary evidence that makes it clear that the builders did not follow the plans with exactitude. The earliest known artist's rendering was done about 1803 by Michel Felice Cornè; the earliest model dates from 1812. But if we cannot see her directly, we can construct a reasonably good image of her first appearance by extrapolation from the draught, from diary and journal entries, and from newspaper articles of the period.

How did Constitution get the nickname "Old Ironsides"?

Constitution fought the British frigate Guerriere on August 19, 1812. According to American seaman Moses Smith, several British shot entered Constitution's hull. "One of the largest the enemy could command struck us, but the plank was so hard it fell out and sank in the waters. This was afterwards noticed, and the cry arose: 'Huzza! Her sides are made of iron! See where the shot fell out!"

As early as 1813 both the press and the ship's officers used the name "Old Ironsides" in print, and she has been called by that name ever since.
