5. Pluto
PLUTO stands for “Pipeline under the Ocean”. The Allied troops needed sufficient fuel to operate all their equipment. As a solution to this, they made a network of flexible underwater pipes running from the Isle of Wight to Port-en-Bessin, the connection point between the Gold beaches and Omaha.
The pipes drew petrol from Britain and supplied it to the Allies in Europe, giving them access to enough fuel for their naval craft, aircraft, and terrestrial vehicles. There were initially two PLUTO pipelines and another one was added afterward. This ran from Dungeness, Kent coast to Boulogne France. More of these pipes were added as the Allies advanced further across the region. Each underwater pipeline measured 3 inches wide and was attached to huge floating spools referred to as ‘conundrums’.
