HMS "Achille" was a 74-gun third-rate ship of the line of the Royal Navy. She was built by Cleverley Bros., a private shipyard at Gravesend, and launched on 16 April 1798. Her design was based on the lines of the captured French ship "Pompée" . She was the fourth Royal Navy ship to be named after the Greek hero Achilles in the French style. Using only the above description and what you know about the world, "HMS "Achille" was launched over 100 years ago." is definitely correct, incorrect, or inconclusive?
