Well by the time the USS Enterprise was commissioned in 1799 she was the 3rd of her name (a 14 x 6 pounder gun sloop later rated as a Brig) and had a successful career.
The 1799 Enterprise was a schooner, not a sloop. She carried a dozen 6-pounders. For the war against the Barbary pirates her crew was boosted from 70 to 90.
In 1811 and 1812 she was converted to a brig. During the war she carried fourteen short 18-pounders and a pair of long 9-pounders as bowchasers.
