The Galloway Atlantic is a 500 hp V12 aircraft engine that was ordered into production toward the end of World War I. It was developed as a V12 configuration of the inline-six Galloway Adriatic, with two Adriatic cylinder banks mounted on a single crankcase.
The Atlantic saw postwar service in Handley Page V/1500 bombers built by Galloway’s parent company, William Beardmore & Co. In contemporary publications the type was often referred to as the Beardmore, or BHP, Atlantic or 500 hp.
In the United States, Galloway Atlantic engines were fitted to the Remington Burnelli RB-2, which was, at the time, the world’s largest commercial freight aircraft. These engines were also a popular choice for smugglers operating fast boats during the prohibition era.
