The USS Constitution, or "Old Ironsides," as it is affectionately known, first hit the seas as one of the first six frigates in the newly formed US Navy of 1797.

The Constitution had both 30 24-pound cannons and also speed. Not only was it technologically sound for its time, but it was also simply unparalleled and undefeated in battle.

Famously, in 1812, the Constitution fought against the HMS Guerriere, whose guns could not pierce the heavily armored sides of the Constitution.

The Constitution is still commissioned by the Navy today, considered the oldest commissioned warship afloat in the world, and the only currently commissioned US Navy ship to have sunk an enemy vessel. It is in every way worthy of the title "greatest warship of all time."
