Original six frigates of the United States Navy

The United States Congress authorized the original six frigates of the United States Navy with the Naval Act of 1794 on March 27, 1794, at a total cost of $688,888.82 (equivalent to $13,588,000 in 2022). These ships were built during the formative years of the United States Navy, on the recommendation of designer Joshua Humphreys for a fleet of frigates powerful enough to engage any frigates of the French or British navies, yet fast enough to evade any ship of the line.
