The Java or Guerriere-class frigate was a series of heavy sailing frigates built for the United States Navy during the War of 1812. Designed to shore up the fledgling Navy, the ships had a miserable service life. Of the six initially planned, only three were laid down, and only two entered service. The two ships of the class had a limited role within the Navy, stemming from poor craftsmenship and wood quality due to their war-time construction.
