Having cancelled their planned 80,000 ton super-liner Oceanic, White Star Line set about building two smaller 27,000 ton vessels.
The first of the duo was named Britannic, and was launched in 1929. Britannic was incorporated into the Cunard-White Star Line when the two companies merged in 1934.
Britannic's maiden voyage set sail on 28 June 1930 on a journey from London to New York with calls at Glasgow and Belfast. Less than five years later, she made her first voyage for Cunard-White Star, this time routing from Liverpool.
Paired with a near identical sister named Georgic, the ship's enjoyed popularity on the Liverpool to London route until the outbreak of World War II. In August 1939 Britannic was requisitioned for war service, becoming a troop ship for the British government.
Britannic was converted to transport over 3,000 troops per voyage. During her career as a troop ship, she transported over 180,000 troops; sailing more than 370,000 miles.
Britannic was eventually returned to Cunard-White Star in 1947 and refurbished in Liverpool. That same year, Cunard bought out the remaining stock in the line; dropping the White Star name. Regardless of this, the line retained Britannic's name and White Star livery.
The post-war Britannic returned to the Liverpool to New York service, commencing voyages in May 1948. She was successful on this route until 1 June 1950 when she collided with the Pioneer Land while transiting the Ambrose Channel. Fortunately damage was minimal and she was able to complete her voyage.
Britannia made her last Cunard voyage on 25 November 1960. At the completion of her transatlantic crossing, she was destored and prepared for scrapping. Britannic sailed for Inverkeithing on 16 December - drawing to a close the era of the White Star Liners.
