RMS Lusitania in 1915 in color! [AI enhanced & colorized]

RMS Lusitania was a British ocean liner that was sunk on 7 May 1915 by a German U-boat 11 miles (18 km) off the southern coast of Ireland, killing 1,198 passengers and crew. The ship sank within 20 minutes after being torpedoed. The sinking presaged the United States declaration of war on Germany. Although the Lusitania sinking was a major factor in building support for a war, a declaration of war did not take place until nearly two years later, after repeated attacks and German use of unrestricted warfare against American shipping.

Lusitania held the Blue Riband appellation for the fastest Atlantic crossing and was briefly the world's largest passenger ship until the completion of the Mauretania three months later. The Cunard Line launched her in 1906 at a time of fierce competition for the North Atlantic trade. She was sunk on her 202nd trans-Atlantic crossing.[2]

German shipping lines were aggressive competitors for the custom of transatlantic passengers in the early 20th century, and Cunard responded by trying to outdo them in speed, capacity, and luxury. Cunard used assistance from the British Admiralty to build Lusitania, on the understanding that the ship would be available as a light merchant cruiser in time of war. She had gun mounts for deck cannons, but no guns were ever installed [Wikipedia].
